The Street + 

Praed Street is not at any time one of London’s brighter thoroughfares. Certainly it ends upon a note of hope, terminating as it does on the fringe of the unquestioned respectability of Bayswater, but for the rest of its course it is frankly lamentable. Narrow, bordered by small and often furtive shops, above which the squalid looking upper parts are particularly uninviting, it can never have been designed as more than a humble annex of its more prosperous parent, the Edgware Road. And then, for no apparent reason, the Great Western Railway planted its terminus upon it, and Praed Street found itself called upon to become a main artery of traffic. + 

It seems to have done very little to adapt itself to its new role. Beyond an occasional grudging widening, it has left the unending streams of buses, of heavy railway lorries, of hurrying foot passengers, to shift for themselves as best they can. It almost seems as though Praed Street regarded Paddington Station as an intrusion, and those who throng to and from it as unwelcome strangers. It had its own interests long before the railway came⁠—one of the termini of the Grand Junction Canal lies within a few yards of its sombre limits. Praed Street watches with indifference the thronging crowds which pass along, and they in turn take little heed of the uninviting thoroughfare through which their journey leads them. + 

Not that these philosophic reflections occupied the mind of Mr. James Tovey, which was far too full of an acute sense of annoyance and discomfort to find room for any other sensations. Mr. Tovey was not an inhabitant of Praed Street, although he lived in its neighbourhood. There was nothing secretive about Mr. Tovey, you could see his name and occupation painted in bold letters over a shop in Lisson Grove; James Tovey, Fruit and Vegetable Merchant. He was, in fact, a greengrocer, and, years ago, when Mr. Tovey had originally employed a small legacy in the purchase of the business, the sign had read: Tovey, Greengrocer, etc. But it was Mr. Tovey’s proud boast that he always moved with the times, and since his neighbours, the butcher and the grocer, had respectively converted themselves into Meat Purveyors and Provision Dealers, he had abandoned the vulgar term of greengrocer for the more high-sounding appellation. + 

Sunday was a day of strict observance with Mr. Tovey, its presiding deity his own comfort. One can hardly blame him for this indulgence, since the rest of the week left him little leisure for repose. His habit was to rise before six, in order to drive the van to Covent Garden. The van, a secondhand Ford, was the subject of the ribald mirth of his acquaintances. Every nonessential part had long since fallen off, as an aged elm sheds its branches, and the essentials were held together by odd pieces of rope. But to any suggestion of the van’s imperfections, Mr. Tovey merely shrugged his shoulders. “ ’Tisn’t ’er looks as matters,” he would reply. “So long as she does ’er job she’ll do for me.” And perhaps this phrase, applied to things at large, was a complete summing up of Mr. Tovey’s philosophy. + 

He opened the shop as soon as he returned from Covent Garden, and kept it open, winter and summer, till a late hour. Lisson Grove shops late, and it was usually ten o’clock before Mr. Tovey could reckon to get his bit of supper. It was therefore natural that so strenuous a week should be rewarded by a relaxation on Sunday. It was his invariable habit to stay in bed till noon, inhaling the savoury smell of the Sunday joint roasting in the kitchen, and only to rise and put on his best suit when the clock struck that hour. The afternoon was usually devoted to the peaceful somnolence of repletion, or sometimes in summer, if Mrs. Tovey’s legs felt equal to accompanying him, to a walk in the park. And in the evening there were always the thrilling columns of the Sunday paper. + 

Mr. Tovey hated to be disturbed in the evening of this day of rest. Especially on such an evening as the present. The day had been an eminently satisfactory one, from his point of view. The sirloin of beef, carefully selected by Mrs. Tovey from the stock of her friend the Meat Purveyor, over the way, had been of uncommon succulence; the Yorkshire pudding crisped to that exact degree of golden delicacy that Mr. Tovey’s heart desired. True, he had had a slight difference of opinion with Mrs. Tovey, but that had merely given a zest to a day which might otherwise have been uneventful. Mr. and Mrs. Tovey never really quarrelled. For one thing they were neither of them of a quarrelsome disposition, and for another they were both too fond of their own comfort to risk its disturbance by domestic rancour. But sometimes they did not see eye to eye, as in the present case. + 

It had begun when Mr. Tovey had come down to the kitchen, and noticed that only two places had been laid at the table. He had raised his eyebrows and glanced towards the massive form of Mrs. Tovey, bending over the glowing range. + 

“Hullo! Where’s Ivy, then?” he asked, in an almost querulous tone. + 

“Gone out with Ted,” replied Mrs. Tovey quietly, from among the saucepans. “He’s taken her home to dinner, and they’re going on to the pictures afterwards.” + 

Mr. Tovey clicked his tongue, his favourite expression of annoyance. Of course, Ted and Ivy had known one another since they were children. Old Sam Copperdock, Ted’s father, was Mr. Tovey’s oldest friend, and they had been near neighbours ever since the latter, as a newly married man, had bought the greengrocery business. Still, Mr. Tovey didn’t altogether like it. Ivy was twenty now, and young Ted Copperdock only three years older. Just the sort of age when young folks get the bit between their teeth and go and get married without a thought of the future. Old Sam was a thorough good chap, and his son was a very nice lad; Mr. Tovey would not have denied either of these facts for a moment. But Ted’s only prospects lay in his father’s shop in Praed Street, and Mr. Tovey had very different views of his only child’s future, very different. + 

Yet he had never put these views into words. Perhaps he would have found it very difficult to do so, for Mr. Tovey’s vocabulary was strictly limited. But they were there, just the same⁠—had been ever since Ivy’s prowess at school had discovered her to be a “scholar.” From that moment Mr. Tovey had been at great pains to educate his daughter to an entirely different state of life from that which it had pleased God to call her. That she was by now tall, distinctly pretty, and extraordinarily self-possessed was not, one supposes, due to the efforts of Mr. Tovey. But she certainly owed the fact that she was an extremely competent shorthand typist to the pains he had devoted to her education. + 

Mr. Tovey, though naturally he would have been justifiably annoyed at such a suggestion, had an incurably romantic core to his plodding and material mind. Of course, in common with most of his class, he firmly believed that human happiness varied exactly with the social scale. “As happy as a king” was to him no mere catchword. He was convinced⁠—and, to do him justice, he drew considerable satisfaction from the conviction⁠—that the members of the Royal Family were the happiest persons in the land, and that this happiness descended in regular gradation through the ranks of the nobility and gentlefolk until it reached acute misery somewhere in the lower strata of those who dwelt in slums. From this outlook on life it necessarily followed that the more he could enable Ivy to better herself, the happier she must ultimately be. + 

How this betterment was to take place, Mr. Tovey never explained. But sometimes he had a vague intangible dream of Ivy, his Ivy, captivating the heart of some susceptible employer, preferably of the upper classes. His eye, diverted for the moment from the business of wrapping up a parcel of leeks, often caught sight of the pictures in the newspaper which he was using for the purpose. “Lady Mary Mayfair (right) and the Countess of Piccadilly (left) on the lawn at Ascot.” Suppose that one day he should proudly open the paper to find Ivy with a smile like that, gracefully posing under the heading “A leader of Society in the paddock at Goodwood”? After all, why not? + 

But it was not until after the second helping of roast beef and Yorkshire that he made any further remark about his daughter to Mrs. Tovey. “I wouldn’t encourage young Ted to hang around Ivy too much, if I was you,” he said, as he pushed aside his plate. + 

“Encourage? He don’t want no encouraging,” replied Mrs. Tovey briskly. “He just comes in, cheerful like, nods to me, asks after you, says a word or two to Ivy, and away they goes together. Things ain’t the same now as they was when we was their age, Jim.” + 

“No, it’s a fact they ain’t,” agreed Mr. Tovey darkly. + 

“But let ’em alone,” continued Mrs. Tovey. “Ivy’s not the girl to make a fool of herself, you ought to know that by this time. Now you can go and sit in your chair by the fire. It’s not the sort of day for the likes of us to be going out.” + 

Mr. Tovey shook his head, as though unconvinced by his wife’s words, and looked out of the window. Much as he might disagree with her on the subject of their daughter, there was no doubt that she was right about the weather. It was the beginning of November, and the month was doing its best to live up to its reputation. A thin mist, precursor of the fog that must surely follow, filled the narrow streets, and through it filtered a cold raw drizzle, through which a few passing pedestrians hurried, muffled up to their ears. + 

Mr. Tovey grunted, and drew his chair up closer towards the fire. The weather could do what it liked, as long as it cleared up before the next morning. He certainly was not going out into it. He composed himself for his afternoon nap, from which he arose refreshed and eager for the lurid pages of his favourite Sunday paper. He studied this intently for some minutes, then turned animatedly to Mrs. Tovey. + 

“That brute what cut up the young woman he was walking out with is committed for trial at the Old Bailey,” he said. + 

“I reckoned he would be, the dirty brute,” replied Mrs. Tovey, who was almost as keen a criminologist as her husband. “And I’d see he didn’t get off, neither, if I was on the jury.” + 

Mr. Tovey turned and looked at her gravely. “ ’Tis all very well for you to talk like that,” he said reprovingly. “It’s a terrible thing to be on a jury when a man’s life depends on what you says. Nobody knows that better than I do, I’m sure.” + 

“Yes, I remember the state you was in that time,” replied Mrs. Tovey. “Dear, dear, best part of a week you was at it, and Ivy just born and all. What was the chap’s name? I remember he was a doctor who’d killed one of his patients by giving him a dose of something.” + 

“Morlandson, Dr. Morlandson,” said Mr. Tovey. “Lord, whenever I eats anything as disagrees with me I dreams of his face a-looking at us from the dock. Fair gave me the creeps, it did, for a long time after. We found him guilty, and I couldn’t help looking at him when the judge put on his black cap and sentenced him. Ugh!” + 

“But they didn’t ’ang ’im after all,” remarked Mrs. Tovey. + 

“No, he was reprieved, I don’t rightly know why. Because he’d been a big pot in his way, I suppose. Twenty years hard he got, though, and serve ’im right. This bloke I’m telling you about won’t get off so easy, though.” + 

Mr. Tovey returned to the perusal of his paper, and the evening wore on, the silence of the cosy kitchen broken only at intervals by the voice of Mr. Tovey, reading in a halting voice some more than usually spicy extract to his wife. Teatime came and went, and still Ivy made no appearance. It was nearly nine o’clock when Mr. Tovey referred to her absence. “I can’t think where that girl’s got to,” he said irritably. “She’s no call to be out all this time.” + 

“Ted’ll have taken her home to have a bite of supper,” returned Mrs. Tovey equably. “His father likes to have her round there, cheers him up, she does. She’ll be back before long, never you worry.” + 

The reply which sprang to Mr. Tovey’s lips was checked by the urgent ringing of the telephone bell in the shop, separated from the kitchen by a door kept locked on Sundays. + 

“Hullo! What’s that?” he enquired in a startled tone. Mrs. Tovey had already moved towards the door. “I’ll go and see,” she replied shortly. Her husband, listening intently, could hear her steps on the bare boards, the sudden cessation of the ringing as she took up the receiver, her voice as she answered, then a pause. + 

Then he heard her call him from the other room. “Somebody wants to speak to you, Jim.” + 

With a muttered objurgation he dragged himself from his chair and went into the shop. His wife handed him the instrument. “Hullo!” he said and for a moment stood listening. + 

“Yes, I’m James Tovey.” A long pause, while Mrs. Tovey vainly tried to make sense of the faint sounds which reached her ears. “What’s that? Oh! a man, you say, thank the Lord for that! I thought for the moment it might be my daughter, she’s out a bit late tonight. Yes! I’ll be along at once.” + 

He put back the receiver and turned to his wife. “That’s a rum show!” he exclaimed, not without a tremor of excitement in his voice. “St. Martha’s Hospital, that was. There’s a fellow been run over, and they can’t find out who he is. The only thing in his pocket is a bit of paper with my name an’ address on. Now, who the dickens can it be?” + 

“Why, young Alf, as likely as not,” replied Mrs. Tovey unemotionally. “Why ’e ’asn’t been run over afore, goin’ about as he does with his ’ead in the air, is more than I can make out.” + 

Alf was the youth employed by Mr. Tovey to deliver the purchases of such of his customers as did not prefer to carry them home wrapped up in newspaper. But Mr. Tovey shook his head at the suggestion. + 

“Not it! Young Alf lives down Camberwell way, and he’s not likely to be up this way of a Sunday. Give us my coat, missus, and I’ll go along and see who it is.” + 

Mr. Tovey struggled into his coat, and turned the collar well up over his ears. It was a most unpleasant evening to be out in, but, after all, it was worth it. His mind had been steeped in sensation all the afternoon, and now he was himself about to take a leading part in some thrilling tragedy. In imagination he could see the account in the next issue of the Paddington Clarion and Marylebone Recorder. Headlines first: “Fatal Accident. Man crushed to death by Motor Bus.” Then his own name: “The body was identified by Mr. Tovey, the well-known Fruit and Vegetable Merchant of Lisson Grove.” This was fame indeed! + 

He stood at the corner of Lisson Grove for a moment, eyeing the buses as they passed him. Through their streaming window panes he could see that they were all full, a row of dejected looking passengers standing in each one of them. There was nothing for it, he would have to walk. It wasn’t very far, anyhow, not more than half a mile at most. + 

Mr. Tovey stepped out smartly along Chapel Street, across the Edgware Road, and entered Praed Street. Despite the depressing weather, the pavements seemed to be full of people, groups of whom overflowed into the roadway, only to be driven back helterskelter by the menacing onrush of the motorbuses. Mr. Tovey picked his way through the crowd with the consciousness of the importance of his mission. So intent was he upon reaching his goal, and, having played his part, upon regaining the comfort of his own fireside, that he scarcely spared a glance for the lighted window above Sam Copperdock’s shop. Ivy was behind that drawn curtain, no doubt. He might drop in and pick her up on his way home. He certainly could not stop now. + 

With a due sense of dignity he climbed the steps of the main entrance of St. Martha’s, and nodded familiarly to the porter in the hall. “My name’s Tovey,” he said, “you rang me up just now to come and identify an accident case.” + 

The porter looked at him incredulously. “Rang you up? ’Oo rang you up? First I’ve ’eard of it.” + 

Mr. Tovey clicked his tongue impatiently. “Why, not more than a quarter of an hour ago,” he replied. “Man been run over, and you couldn’t find out who he was.” + 

“We ain’t ’ad no accidents brought in the ’ole blessed day,” returned the porter stolidly. “You’ve made a bloomer, you ’ave. Wait ’ere a moment while I goes and sees if anybody knows anything about it. Tobey, did you say your name was?” + 

“Tovey!” replied that individual angrily. The porter turned his back upon him and disappeared, his boots clattering noisily upon the tiled floor. Mr. Tovey, with a sudden reaction from his excited imaginings, stood cold and miserable in the centre of a puddle formed by the drops from his overcoat. + 

After what seemed an interminable time the porter returned. “Somebody’s bin pulling your leg,” he said, with a malicious grin. “We ain’t ’ad no accidents, and nobody ’ere ain’t ever ’eard of you. Didn’t get the name of the ’orspital wrong, did you? Wasn’t St. George’s, was it, or maybe St. Thomas’s?” + 

Mr. Tovey shook his head. “No, it was St. Martha’s, right enough,” he replied. A sudden wave of anger at the hoax which had been played upon him surged through his brain, and without another word he turned and strode out of the hall. It was monstrous that he, a citizen and a ratepayer, should be dragged out into the streets on a fool’s errand like this. With his grievance rankling to the exclusion of every other thought, he pushed his way along Praed Street, his head down, his hands crammed into his overcoat pockets. The drizzle had turned to sleet, and the sting of it on his face added to his ill-humour. + 

Ahead of him was the Express Train, a public-house which had presumably been built and named at the time of the coming of the railway. It was closing time by now, and a stream of gesticulating figures was being disgorged upon the crowded pavement. Mr. Tovey looked up as he heard the turmoil. The cold air and comparative darkness, after the warmth and light of the bar, seemed to have had an unsteadying effect upon the ejected guests. They lurched about the pavement singing snatches of ribald songs, arguing heatedly in loud voices. + 

Mr. Tovey frowned. Nice way to spend a Sunday evening! Thank God, he didn’t live in Praed Street, anyhow. He wasn’t going to be barged off the pavement by a lot of drunken hooligans, not he. Putting his head a trifle further down, like a bull about to charge, he strode straight ahead in an undeviating line. One man lurched into him, another jostled him from behind, and a menacing voice, its effect somewhat marred by a loud hiccup, called out, “ ’ere, ’oo the ’ell d’yer think you’re pushin’?” + 

And then Mr. Tovey, with a queer strangled cry, suddenly collapsed in a heap upon the muddy pavement. + 

The Herbalist + 

It is the proud boast of our modern educationalists that the process of forcing knowledge down unwilling throats, known as compulsory education, has resulted in the triumph of science over superstition. Alchemy and astrology, the magic of the Middle Ages, have given place to chemistry and astronomy, the mysteries of which are displayed before the wondering eyes of the elementary scholar. The Age of Superstition is commonly supposed to have fled before the progress of the Age of Materialism. + 

This supposition is demonstrably false. At no other age in the earth’s history has superstition owned so many votaries. From the most rapt spiritualist to the man who refuses to walk under a ladder, the world is full of people who allow superstition to play an important part in their lives. In the neighbourhood of Praed Street fortune tellers and interpreters of dreams are superstition’s most popular ministers, though it may come as a surprise to many that a brass plate nailed to the door of a house in the Harrow Road advertises the existence of the British College of Astrology. + 

Even alchemy is not without its devotees, although the alchemist has forsaken the more picturesque apparatus of his stock-in-trade. He now owns a small shop, the darker the better, and fills the windows with a curious assortment of dried herbs, each with a notice affixed to it describing its virtues. You may go in and buy two pennyworth of some dried plant with a high-sounding Latin name, the herbalist assuring you that, mixed with boiling water and drunk as tea, it will cure the most obscure disease. If you have sufficient faith, it probably will. + 

But this is the least of the herbalist’s abilities. It is, in fact, merely the outward sign of an inward and spiritual wisdom. You can consult him, in the little back parlour behind the shop, upon all manner of subjects which you do not care to mention to your friends. And, for a consideration, he will give you advice which you may or may not follow. At all events, if the herbalist knows his business, he will contrive to command respect, and, at the same time, earn a surprising number of shillings. + 

The establishment of Mr. Elmer Ludgrove, the herbalist of Praed Street, was almost exactly opposite that of Mr. Samuel Copperdock, who dealt in another herb, namely tobacco. There was a considerable contrast between the two shops; that of Mr. Copperdock was always newly painted, and its windows full of tins and boxes bearing the brightest labels known to the trade. The herbalist’s window, on the other hand, was low and frowning, backed by a matchboard partition which effectually precluded any view into the shop. Between the partition and the glass were displayed the usual bunches of dried plants and dishes containing seeds and shrivelled flowers. The door of the shop closed with a spring, and if you had the curiosity to push this open you found yourself in a dark little room, across the centre of which ran a narrow counter. The noise of your entry would bring Mr. Ludgrove through a second door, shrouded by a heavy curtain, and he would ask you politely what he could do for you. + 

Mr. Ludgrove’s appearance was certainly in keeping with his calling. He was tall and thin, with a pronounced stoop and a deep but not unpleasant voice. But it was his head that you looked at instinctively. Above the massive forehead and powerfully-chiselled features was a wealth of long, snow-white hair, balanced by a flowing beard of the same colour. His eyes, behind his iron-rimmed spectacles, looked at you benignly, but they conveyed the impression that they saw further into your mind than the eyes of the mere casual stranger. If you were a mere customer for some simple remedy, you came away with the pleasant feeling of having been treated with unusual courtesy. If your business was such that Mr. Ludgrove invited you to discuss it with him in the room behind the curtain, you very soon found out that behind Mr. Ludgrove’s impressive presence there lay a wealth of wisdom and experience. + 

Praed Street, which beneath its squalor possesses a vein of native shrewdness, had very soon estimated Mr. Ludgrove’s worth. That neighbourhood had very few secrets, romantic or sordid, which, sooner or later, were not told in halting whispers behind the sound-defying curtain. And, whatever the secret might be, the teller of it never became swallowed up again in the stream of humanity which flowed past Mr. Ludgrove’s door without some grain of comfort, material or moral, which as often as not had cost the recipient nothing. + 

Mr. Samuel Copperdock had from the first taken a great fancy to old Ludgrove, as he called him. When the name had first appeared over the shop, which had stood empty for years, almost opposite his own premises, he had been intrigued at once. Curiosity⁠—or perhaps it was not mere vulgar curiosity, but a thirst for information⁠—was one of Sam Copperdock’s chief characteristics. He must have been one of Mr. Ludgrove’s first customers, if not the very first, for on the very day the herbalist’s shop was opened he had walked across the road, pushed open the door, and thumped upon the counter. + 

He stared quite frankly at Mr. Ludgrove as the latter came into the shop, and opened the conversation without delay. “Look here, you sell medicines, don’t you?” he inquired briskly. + 

Mr. Ludgrove smiled, and with a slight gesture seemed to indicate the long rows of drawers behind the counter. “Yes, if you like to call them such,” he replied gently. “What particular medicine do you require?” + 

“Well, I’m terrible troubled with rheumatics,” said Mr. Copperdock. “Mind, I don’t hold with any of them quack mixtures, but I thought I’d just step across and see if you had anything that was any good.” + 

Mr. Ludgrove smiled. Certainly Mr. Copperdock, short, red-faced, and inclined to stoutness, looked the picture of health. “Rheumatism, eh?” he remarked. “How long have you suffered from it?” + 

Mr. Copperdock laughed. There was something disarming in the attitude of this herbalist fellow. Besides, deception in any form was not Mr. Copperdock’s strong suit. + 

“Well, to tell the truth, I don’t worry much about them rheumatics,” he replied. “I came across neighbour-like, mainly to see what sort of a place you’ve got here.” + 

“I’m sure you’re very welcome,” replied Mr. Ludgrove courteously. The two men leant on the opposite sides of the counter, chatting for a while. At last Mr. Copperdock straightened himself up, half reluctantly. “Well, I must get back to business, I suppose,” he said. + 

“Look here, how serious were you about that rheumatism?” interposed Mr. Ludgrove. “Do you ever feel any twinges of it?” + 

“Oh, sometimes,” replied Mr. Copperdock nonchalantly. “Can’t say as it worries me much, though.” + 

“If you take my advice, you’ll stop it before it gets worse,” said Mr. Ludgrove, opening a drawer and taking from it a scoopful of some parched-looking seeds. “If you put a teaspoonful of these into half a tumbler of boiling water, and drink the liquid twice a day after meals, you won’t have any further trouble.” + 

He had poured the seeds into a paper bag as he spoke, and handed them across to Mr. Copperdock. + 

“How much?” asked the latter rather awkwardly, putting his hand in his trouser pocket. + 

But Mr. Ludgrove waved him away. “Try them first, my dear sir,” he said. “Then, if you find they do you good and you want some more, we’ll talk about payment.” + 

That first introduction had, in the course of years, ripened into friendship. Nearly every morning Mr. Copperdock was in the habit of stepping across the road and having a chat with old Ludgrove. Mr. Copperdock loved somebody to talk to. If you went into his shop to buy a packet of your favourite cigarettes you were lucky if you got out after less than five minutes conversation. In the evening, after the shop was closed, a select company in the saloon bar of the Cambridge Arms gave Mr. Copperdock the opportunities he sought. Mr. Copperdock, who had been a widower for many years, always talked of retiring in favour of his only child Edward. + 

“Does the lad good to be left in charge of the shop for a bit,” was his father’s justification for his morning talk with his friend the herbalist. And Mr. Ludgrove, whose trade was never very brisk in the mornings, always seemed glad to see him. + 

Thus, on the Monday following Mr. Tovey’s adventure it was to Mr. Ludgrove that Sam Copperdock hastened to unbosom himself. He was simply bursting with news, and he watched impatiently until the unlocking of Mr. Ludgrove’s shop door indicated that that gentleman was ready to receive visitors. Then he bustled across the road and into the shop. “Are you there, Ludgrove?” he called out. + 

“Come in, come in, Mr. Copperdock,” replied a welcoming voice from behind the curtain, and the tobacconist, with an air of supreme importance, passed into the inner room. + 

The room was half-parlour, half-laboratory. One side of it was entirely occupied by a long bench, upon which stood a variety of scientific instruments. At the other side, placed round a cheerful fire, were two comfortable armchairs, in one of which sat the herbalist himself. With a hospitable gesture he motioned Mr. Copperdock towards the other, but the tobacconist was too excited to perceive the invitation. + 

“I say, have you heard the news about poor Jim Tovey?” he exclaimed, without preliminary. + 

“My dear sir, I read my paper pretty thoroughly every morning, as you know,” replied Mr. Ludgrove with a glance at the sheet which lay on the table by his side. + 

But Sam Copperdock merely snorted impatiently. “Newspaper!” he exclaimed, “why, the newspapers don’t know nothing about it! I tell you I’ve been up three parts of the night over this affair.” + 

“Indeed? Then you probably know all the details,” replied the herbalist. “If you can spare the time, I should be very interested if you would sit down and tell me all about it.” + 

This was exactly what Mr. Copperdock had meant to do. He sank heavily into the chair with a portentous sigh. “Terrible thing, terrible,” he began, shaking his head. “I’ve known Jim Tovey ever since he first took that shop in Lisson Grove, and to think that a thing like this should happen to him! And his poor daughter Ivy spent the best part of the evening at my place, too.” + 

Mr. Ludgrove, who knew his friend’s methods of expression, was careful not to interrupt, and after a short pause the tobacconist resumed his relation. + 

“First I knew of it was from my boy Ted. You see, it was like this. Ted’s very sweet on Ivy, and a nice girl she is, too. None of your flyaway misses, but a nice steady girl what’ll make her way in the world. Ted brought her to my place for dinner, then they spends the afternoon at the pictures, and comes back for supper. About half-past nine or maybe quarter to ten Ivy says it’s time she was getting home, and she and Ted goes out together. I was thinking Ted was a long time a-seeing of her home, since it was a shocking night, and they weren’t likely to dawdle on the way, when in he comes white as a sheet, and all of a tremble. ‘Dad,’ he says, ‘Ivy’s father’s been murdered.’ + 

“Well, I thought the boy had gone off his head. ‘Murdered?’ I says. ‘Why, what do you mean? Who’d want to murder Jim Tovey, I’d like to know?’ Then after a bit I manages to get the whole story out of him. It seems that when he and Ivy got to Lisson Grove, Jim Tovey was out. He’d been called to St. Martha’s to identify an accident case. He stayed there for a bit, when suddenly the door bell rings. Mrs. Tovey answers it, and in comes a policeman, with a message that Mrs. Tovey and Ivy were wanted at St. Martha’s at once. Mrs. Tovey goes upstairs to put her things on, and Ivy goes with her. Then the policeman asks Ted if he’s a friend of the family, and when he says he is, tells him that poor Jim has just been murdered in this very street, not a couple of hundred yards from where we’re sitting now.” + 

Mr. Ludgrove nodded. “A most extraordinary affair altogether,” he commented. + 

“Ah, you may well call it extraordinary,” agreed Mr. Copperdock significantly, “there’s more in it than meets the eye, that’s what I says. Well, as soon as I hears this I thinks of those two poor women, and off I goes to St. Martha’s to see if I could be of any use. There I finds a police inspector who asks me who I was. When he hears I was Jim Tovey’s oldest friend he tells me all about it. It seems that a policeman who had his eye on the lads coming out of the Express Train⁠—they’re a rough crowd, as you know⁠—saw a man fall down and then heard a lot of hollering. Thinking there was a scrap he went over and found Jim Tovey on the ground with a lot of fellows standing round him. It didn’t take him long to find out that Jim was dead, but nobody seemed to know how it happened. There was a crowd on the pavement outside the pub, and it was a foggy sort of night that you couldn’t see very clearly in.” + 

“I know,” put in Mr. Ludgrove. “I was out about that time myself. I always go for a walk after supper, rain or fine; it’s the only chance of exercise I get.” + 

“Yes, I know you do,” agreed Mr. Copperdock. “I often wonder you don’t catch your death of cold. Well, the policeman calls up the ambulance, and they gets poor Jim round to St. Martha’s. There they very soon finds out what’s the matter. There’s a great long knife, in shape rather like a butcher’s skewer, but without a handle, sticking into him. And the point’s right through his heart.” + 

Mr. Copperdock paused dramatically. There was no doubt that he was thoroughly enjoying himself, and Mr. Ludgrove was far too good a listener to interrupt him. + 

“I took Mrs. Tovey and Ivy home,” he continued, “and the Inspector told me he’d come and have a chat with me later. It was past midnight when he turned up, and then of course he wanted to know all about poor Jim, and whether I knew of anybody who had a grudge against him. He couldn’t have come to a better man, for I know a lot about Jim Tovey that I don’t suppose he ever told anybody else. You’ve heard of the Express Train gang, I suppose?” + 

Mr. Ludgrove nodded. “It consists, I believe, of a number of young men who frequent the racecourses, and who meet in the evenings at the Express Train,” he replied. + 

“They were the fellows outside the pub when poor old Jim was murdered,” continued Mr. Copperdock significantly. “Now the police, who know a lot more than most people give them credit for, know all about that gang. They’d had every man jack of them rounded up before the Inspector came to see me and put them through it. As the Inspector said, if Jim Tovey had been beaten up with bits of iron pipe, or something like that, he could have understood it. But the knife trick didn’t sound like the gang, somehow. None of them had the guts for deliberate murder like that, and there seemed no reason why they should have set upon Jim Tovey. He’d nothing to do with racing, and he wasn’t likely to be carrying a lot of money about with him.” + 

Again Mr. Ludgrove nodded. “I see the point,” he said. + 

“Yes, but you don’t know what I know,” replied Mr. Copperdock darkly. “The leader of the gang is young Wal Snyder. Decent lad he used to be, I knew his father years ago before he died. He and my Ted used to go to school together, and I managed to get him a job as errand boy. Then he got into bad company, run away from his job, and has been hanging about doing nothing ever since. Now, if you please, this young rip had the sauce to walk into Tovey’s shop a few weeks ago, and ask if Miss Ivy was in. Jim asks him what he wants her for, and he says that he knew her as a child, and as she’d turned out such a fine girl he’d like to take her out on the spree one fine evening. Jim tole me he fair lost his temper at that; I don’t know exactly what he said to young Wal, but he let him know pretty straight that if he found him hanging round Ivy he’d put the police on his track. The young scamp cleared out, telling him he’d better look out for himself.” + 

“Ah, this throws a new light upon the matter!” commented Mr. Ludgrove, with polite interest. + 

“Better look out for himself,” repeated Mr. Copperdock with careful emphasis. “A regular threat, mark you. Jim didn’t say anything about Wal to Ivy or her mother, you never know how women will take these things. Of course, I told the Inspector about it, and he took it all down in his book. He’d already seen Wal, together with the rest of the gang. It seems they’d had a pretty good week, and most of ’em confessed they were a bit on, and didn’t remember much after they was chucked out of the pub. But young Wal said he remembered an old chap barging into him⁠—he said he didn’t recognize him⁠—and just behind him was a fellow who looked like a seaman. He couldn’t say much about this other fellow, except that he had a sort of woollen cap covering his head, a fierce-looking black beard, and a great scar right across his cheek. Said he looked like one of them Russian Bolsheviks. Of course, there was a lot of people on the pavement, but he was the only one he noticed.” + 

Mr. Ludgrove smiled. “I am inclined to think that the story does credit to the young man’s imagination,” he said quietly. “I can’t say that I’ve ever seen a Bolshevik sailor wandering about Praed Street on a Sunday evening.” + 

“Nor hasn’t anybody else,” replied Mr. Copperdock scornfully, “what’s more, the policeman, who was on the spot pretty sharp, didn’t see anybody like this man in the crowd. There’s no question but what Wal Snyder invented this story to cover himself. It’s all plain as daylight to me⁠—ah, but there’s one thing I haven’t told you. Remember I said that poor old Jim had been sent for to St. Martha’s to identify an accident case? Well, that was all my eye. There hadn’t been no accident and St. Martha’s hadn’t rung him up at all. It was just a trick to get him out into Praed Street.” + 

“It ought to be possible for the police to trace where the call came from,” suggested Mr. Ludgrove. + 

“Of course. The Inspector told me they’d done that already, but it didn’t get them much further. The call came from one of the boxes at Paddington station, one of them automatic contraptions where you press the button when you’re through. If you’re sharp with the button, there’s nothing to tell the people you’re speaking to that you’re speaking from a box. And, of course, at a place like Paddington there’s no one to see who goes in and out of those boxes.” + 

“I see. And where was Wal Snyder when the call was made?” + 

“Oh, in the Express Train all right. He’d got his alibi fixed up, no fear of that. Put one of his pals on to that job, the cunning young devil. And then, of course, he’d watch till Jim came past the pub on his way home, and the rest was easy.” + 

“And what did your friend the Inspector think of all this?” inquired Mr. Ludgrove. + 

“He didn’t say much,” confessed Mr. Copperdock. “But the police ain’t such fools as you might think. Young Wal Snyder will have to go through it, you mark my words. Well, I’d best be getting back home. You never know when I shan’t be wanted to give evidence or something.” + 

And with that he rose and stalked out of the back room, leaving Mr. Ludgrove with a thoughtful expression on his face. + 

III + 

The Inquest + 

The inquest upon Mr. Tovey, although it was reported at length in all the evening papers, did not throw any further light upon the identity of his murderer. The knife was produced and handed round for examination. There was, however, nothing extraordinary about it, except perhaps its inordinate length and the fact that it had no handle. + 

A cutler, called as an expert witness, identified it as the blade of a paper-cutter’s knife, carefully ground down so as to obliterate the maker’s name and also to produce an edge all the way up as well as at the point. Such blades were usually supplied with a wooden handle, into which they fitted loosely, being secured by means of a setscrew. This witness agreed that knives of this type were rarely seen in ordinary use, but that they were made in considerable quantities for use in certain trades. There would be no difficulty in purchasing one. + 

Wal Snyder, with a mixture of glibness and injured innocence, gave his version of the affair. But the atmosphere of the coroner’s court, so painfully reminiscent of the police court, reduced him in a very short time to stuttering incoherence. Yes, he had caught sight of somebody just as the dead man fell. Hadn’t never seen him before, biggish fellow with a lot of black hair, and an ugly-looking cut across his cheeks, like as if he’d been slashed with a knife. Asked why he thought he was a sailor, Wal replied that he wore a woollen cap and a coat and trousers like the sailors wear. He knew because he had got pals down the West India Dock Road. Asked again if he had any reason to suppose that this was the man who stabbed the deceased, Wal became more confused than ever. Well, then, had he seen him strike the blow? Wal had not, but incautiously advanced the opinion that he looked just the sort of cove who’d do a thing like that. + 

This brought the whole weight of the coroner’s displeasure upon his unlucky head. He was told to stand down and not talk nonsense. Then his appalled ear was assailed by an exact and monotonous catalogue of the misdemeanours committed by himself in particular and the Express Train gang in general; things which he fondly believed were known only to himself and a few chosen associates. They ranged from petty larceny to assault and battery, but the Inspector who recited them seemed to treat them with contempt. He smiled as he replied to the coroner’s questions. + 

“No, sir, I don’t believe any of them have the intelligence or the pluck to plan a murder like this,” he said, “nor do I think that they would be likely to play any of their games outside the Express Train, under the very eyes of the police. In fact, sir, we have no evidence that any of them was in any way connected with the crime.” + 

The constable who had been first on the scene proved an excellent witness, and earned the coroner’s commendation. He had been standing, at about half-past nine on the previous Sunday evening, on the pavement opposite the Express Train. There had been complaints of disorderliness in Praed Street at closing time. There had been a large number of people passing along the pavement, and the sudden surge of twenty or thirty men from the door of the public house caused a few moments confusion. He heard a lot of shouting, then saw a man fall on the pavement. A group immediately gathered round the fallen man and hid him from sight until he pushed them aside. + 

Asked if he could form any estimate of the time which elapsed between his seeing the man fall and his reaching his side, the constable said, it could not have been more than fifteen seconds. He did not see anybody resembling the black haired sailor described by a previous witness, but had there been such a man he would have had ample time to disappear in the crowd in the interval. He could not distinguish faces across the street, it was too foggy. His ambulance training had convinced him that the deceased was dead when he reached him. + 

A house-surgeon at St. Martha’s described the wound. It would not require the exercise of any great force to drive the knife in, but the location of the blow showed a certain knowledge of anatomy. The knife had passed right through the outer clothing of the deceased; it was only when the body was undressed that it was discovered. It seemed difficult to imagine how a man holding a blade without a handle could have driven it in so far. Death from such a wound would be practically instantaneous, but there would be no external hæmorrhage. + 

The coroner, addressing the jury, made it quite plain that although there was no doubt how deceased met his death there was no evidence as to how the blow was delivered. The jury, taking their clue from his remarks, found that the deceased had been murdered by some persons or persons unknown, and added a rider expressing their sympathy with his widow and daughter. + 

Mr. Samuel Copperdock, who had escorted Mrs. Tovey and Ivy to the court, brought them back to his place in Praed Street for tea. In Mr. Copperdock’s mind there still lingered a strong suspicion that Wal Snyder and the Express Train gang were in some way mixed up in the affair. His disappointment that someone had not been brought to book made him unusually silent, and it was not until tea was over, and he and Mrs. Tovey were ensconced in armchairs in his comfortable parlour, that he resumed his accustomed cheerfulness. + 

Mrs. Tovey, a voluminous figure in the deepest of black, had taken the tragedy with her accustomed philosophy. She was not the sort of woman to give way to despair; and all her life she had faced the ups and down of fortune with the same outward placidity. Her inner feelings were her own concern; even her husband had never attempted to probe their depth. Besides, Mrs. Tovey belonged to a class which cannot afford to let sentiment interfere with the practical considerations of the moment. + 

“I shall keep on the business,” she was saying. “ ’Tisn’t as though I’d been left without a penny, in a manner of speaking. Jim had a tidy bit put away; he always used to say he was saving it up for our old age. Then there’ll be the insurance money. Ivy’s a good girl, she hasn’t cost us nothing for the last year or two, and it’s her I’m thinking of mostly. She’ll want a home yet for a bit, and she couldn’t have a better one.” + 

Mr. Copperdock glanced over his shoulder towards the other end of the room, where Ivy and Ted were holding an earnest conversation in low tones. It was Thursday afternoon, early closing day, and the shop below was shut, a circumstance for which Ted appeared devoutly grateful. + 

“I shouldn’t wonder if you lost Ivy before very long,” said Mr. Copperdock slyly. “But she’s a good girl, as you say. But you’ll never manage the business by yourself, Mrs. Tovey. Who’s going along to do the bit of buying of a morning?” + 

“I’ll manage easy enough,” replied Mrs. Tovey confidently. “I shall take young Alf into the shop, and get another lad to drive the van. You’ll find I’ll manage to rub along very comfortable, Mr. Copperdock.” + 

They entered upon an earnest discussion of the science of greengrocery, heedless of the equally earnest discussion which was going on behind their backs. + 

“No, it’s no use, Ted, not yet,” Ivy was saying. “You none of you seem to understand quite. It’s different for Mum; she’s got the business to look after, and she doesn’t think of anything else. I can’t forget how good Dad always was to me, and we just couldn’t do anything he wouldn’t have liked.” + 

“You mean he wouldn’t have liked you to⁠—to walk out with me?” put in Ted, half resentfully. + 

Ivy blushed in spite of herself. “It wasn’t that, exactly,” she replied. “Mind, he never said anything to me, but I’ve got it out of Mum since. He always wanted me to⁠—to get on in the world, and be a credit to the education he’s given me. And I feel that even now he’s dead, I’ve got to try and do what he wanted.” + 

“It isn’t that there’s anybody else?” he suggested with a note of anxiety in his voice. + 

“There isn’t anybody else, Ted,” she replied, looking him straight in the face. “But I’m not going to promise anything until I’ve got over the shock of his being killed like that. Oh, Ted, who can have done it? He hadn’t an enemy in the world, not a real enemy, I mean.” + 

Ted shook his head helplessly. “I can’t make it out,” he replied. “I can’t believe Wal Snyder had anything to do with it. After all, if⁠—if he wanted to be friends with you, it wasn’t the way to go about it.” + 

“Wal Snyder must have known perfectly well that I’d never have had anything to do with him,” exclaimed Ivy indignantly. The disclosure of that episode at the inquest had roused her to a pitch of anger she rarely displayed. “Besides, he’s too much of a worm to do a thing like that. I’d like to see him hanged, just the same.” + 

Ted tactfully disregarded this piece of feminine logic. “It must have been some lunatic, or perhaps, whoever it was mistook your father for someone else,” he replied vaguely. + 

“And sent him that telephone message first,” she struck in, with a touch of scorn. “No, poor Dad was murdered deliberately. Oh, Ted, if only I were a man, and could find out who did it!” + 

Ted, looking at her clenched hands and tear-filled eyes, felt suddenly the urge of a great resolve. “Ivy, if I were to find out who it was, would you marry me?” he exclaimed impulsively. + 

Her eyes dropped before his ardent gaze. “Perhaps,” she murmured. + 

Their further conversation was interrupted by the stately rising of Mrs. Tovey from her chair. + 

“Come along, Ivy,” she said. “It’s time we were getting along home.” + 

Ivy rose obediently, as Mr. Copperdock helped her mother into her cloak. “Ted’ll see you home, Mrs. Tovey,” he said. “I don’t like the thought of your being about the streets alone.” + 

“That’s very kind of you, Mr. Copperdock,” replied Mrs. Tovey. “I really don’t know what I should have done if it hadn’t been for all your goodness. You’ll come back to our place tomorrow and have a bit of something after the funeral?” + 

“I’d be very glad to, Mrs. Tovey,” said Mr. Copperdock. He walked with them as far as the door of the shop, and stood there a few seconds, until he lost sight of Mrs. Tovey’s ample form among the crowd. Then he walked slowly up the stairs, and flung himself into his own particular chair. + 

“I wonder if she suspects anything?” he muttered, with a reflective frown. “I’ll have to go cautious-like, I can see that.” + 

Mr. Copperdock sat for a long time, motionless, his usually cheerful face furrowed in deep thought. He hated being alone at any time, but somehow this evening it was doubly distasteful. Ted was a long time coming back; no doubt Mrs. Tovey, hospitable soul, had asked him to step in. It was no good stepping across to Elmer Ludgrove’s; Thursday afternoon was that gentleman’s busiest day of the week. The herbalist never closed on Thursday. His customers were for the most part people who were engaged in trade, and the weekly half-holiday was their only opportunity for consultations. Also it seemed a long time before it would be his usual hour for going to the Cambridge Arms. Mr. Copperdock consoled himself with the thought that, as one who had actually attended the inquest, he would not lack an attentive audience. + 

In due course Ted came back, with a suppressed light of excitement in his eyes. He said very little until they had finished tea, and then, apropos of nothing in particular, he burst out with the subject which occupied his mind. “I say, Dad, I would like to find out who killed poor old Tovey!” he exclaimed. + 

Mr. Copperdock glanced at him in astonishment. “Would you, my lad?” he replied sarcastically. “Think you’re a sucking Sherlock Holmes, perhaps? You take it from me, if the police can’t lay their hands on the chap, ’tain’t likely you will.” + 

Ted sighed heavily. In his heart of hearts he was of the same opinion himself. But the magnificence of the reward had blinded him to the difficulties which lay in his path. In every thriller which he had ever read the hero had at least the fragment of a clue to work upon. But rack his brains as he would, Ted could not hit upon the faintest idea of how to set about looking for one. + 

His father continued to look at him with a not unkindly smile. “I dessay you think that Ivy would give a lot to know, eh?” he said, his native shrewdness carrying him straight to the point. “Well, I wouldn’t be disheartened if I was you. Women’s queer folk, and they often takes the will for the deed, as the saying is. But you stick to the tobacco trade, my boy, and don’t go trying no detective tricks on your own, or you’ll find yourself in trouble.” + 

It was not until the following evening that Mr. Copperdock had a chance of a word with Mr. Ludgrove. The excitement engendered by Mr. Tovey’s funeral had kept him busy all the morning, and on his return from that ceremony he had found the herbalist’s shop full of people. But as he was coming back from his evening visit to the Cambridge Arms, he overtook Mr. Ludgrove, who was strolling with a leisurely air along the pavement of Praed Street. + 

They were glad to see one another. “I have been hoping for a chance of a chat with you ever since yesterday,” said Mr. Ludgrove. “Of course, I read the report of the inquest in the papers, but naturally I should be interested in a fuller description. As you see, I am on my way home from my usual evening stroll. Would you care to come in for a few minutes?” + 

Mr. Copperdock laid his hand on his friend’s arm. “No, no, you come over to my place,” he replied hospitably. “Ted’s sure to have a decent fire going, and there’s a bottle of whiskey in the cupboard. And it’s rarely enough you find time to come and see me, and that’s a fact.” + 

Mr. Ludgrove agreed, and for the second time the tobacconist went over the story of the inquest. His son listened attentively, not so much to his father’s words as to the comments of the herbalist. He had great faith in Mr. Ludgrove’s wisdom, and he felt that at any time he might suggest some clue which could be followed up. + 

But Mr. Ludgrove disappointed him. “It is really the most remarkable affair,” he said as his friend came to the end of his recital. “I confess that I have puzzled over it more than once since last Monday morning. In fact, I have no doubt that I shall amuse myself by speculating upon it during the weekend.” + 

“Going away?” asked Mr. Copperdock incuriously. + 

Mr. Ludgrove nodded. “I hope to catch the 12:35 from Liverpool Street tomorrow,” he replied. + 

“Weed hunting, as usual?” said Mr. Copperdock facetiously. + 

“If you like to call it so,” answered Mr. Ludgrove. “As you know, I employ most of my weekends looking for our rarer English plants. It has become the custom to sneer at the simple remedies of our ancestors, but I assure you that there are plants growing in the hedgerow, if one can only find them, which will cure almost any human complaint, and it is my favourite practice to seek for them.” + 

Mr. Copperdock shook his head. “Can’t say as I should find much fun in it,” he said. “Too lonely a business altogether. I likes to have someone to talk to when I’m on a holiday. And where might you be going this time?” + 

“A little place I know in Suffolk, not very far from Ipswich. Now why don’t you come with me, Mr. Copperdock? I shall stay at the inn, a most pleasant little place, and we could go out searching for plants together.” + 

But Mr. Copperdock was not to be tempted. “It’s very good of you, I’m sure,” he replied. “But, as a matter of fact, the country isn’t very alive, leastways not at this time of the year. Perhaps I’ll come with you some time in the summer, if you’re going to stay at a decent little pub. Some of them country pubs ain’t half bad if you’re thirsty.” + 

After a little further conversation Mr. Ludgrove took his departure, and Mr. Copperdock, after a final drink, retired to bed. But it is to be feared that his thoughts gave him very little rest. He almost regretted that he had not accepted Ludgrove’s invitation. For it was being slowly borne in upon him that his agitation would drive him to confide in the wisdom of the herbalist. Ludgrove could be trusted not to give him away, and would certainly give him good advice. + 

IV + 

The Poisoned Pipe-Stem + 

Mr. Ludgrove returned from Suffolk by a late train on Sunday night, burdened with a capacious suitcase, which he laid on the bench in the inner room. He made himself a cup of cocoa, and then proceeded leisurely to unpack the case. + 

It contained a carefully arranged mass of plants, which he laid out in rows, attaching to each a label upon which he scribbled its name. He was thus busily engaged, when he was interrupted by a loud knocking upon the door of the shop, which he had locked behind him. + 

The herbalist was not a man who allowed himself to be disturbed by trifles. He merely smiled and glanced at his plants, not a half of which were yet properly classified. Then he went towards the door. It had sometimes happened that one of his clients, in urgent need of his services, had hammered on the door during the hours when the shop was shut. Mr. Ludgrove, if he happened to be within, made a point of answering these summonses. At any hour he was prepared to do what he could to relieve pain or anxiety. + 

The door opened, disclosing a short, stout figure upon the step. The rather austere lines of Mr. Ludgrove’s face widened into a smile of hospitable welcome. + 

“Come in, Mr. Copperdock!” he exclaimed. “I haven’t been back more than a few minutes, but there’s a fire in the back room.” + 

Mr. Copperdock nodded. “Thanks, Ludgrove,” he said, as he came in. “I know you’re just back, I saw you come in. And I thought to myself that this was a very good chance of having a few minutes’ chat with you.” + 

“I’m only too glad you came over,” replied Mr. Ludgrove, leading the way to the back room. “Bring that chair up closer to the fire. I’ve just made myself a cup of cocoa. Will you have one, too? the kettle’s still boiling.” + 

“Not for me, thank you kindly all the same,” said Mr. Copperdock. “Cocoa’s not exactly in my line. A man of my age can’t afford to put on weight, you know.” + 

His eyes strayed towards a cupboard in the corner of the room, the door of which his host had already opened. From it appeared a bottle of whiskey and a siphon, which were placed on the table within reach of Mr. Copperdock’s hand. At a gesture from Mr. Ludgrove, the tobacconist poured himself out a drink and held it to his lips. It was noticeable that his hand trembled slightly as he did so. + 

For a minute or so Mr. Copperdock sat silently in his chair, glancing nervously about the room. It was obvious that he had something on his mind, but could not find the words in which to unburden himself. His host, skilled in the art of encouraging the tongue-tied, appeared not to notice his confusion, and strolled over towards the bench upon which his harvest was laid out. + 

Mr. Copperdock’s eyes followed him. “Hullo, did you bring that lot back with you this time?” he enquired in a tone which he endeavoured to render conversational. + 

“Yes, they’re rather a good collection,” replied Mr. Ludgrove. “There are one or two quite scarce plants among them, of which I have been anxious to secure specimens for a long time. I had a most enjoyable time. You ought to have come with me, Mr. Copperdock.” + 

“I wish I had, I’d have been saved a deal of worry,” said Mr. Copperdock fervently. Then, with scarcely a pause, he added, “Do you know old Ben Colburn?” + 

“The baker at the other end of the street?” replied Mr. Ludgrove. “I always buy my bread at his shop, but I hardly know Ben Colburn himself, I have seen his son Dick several times. Isn’t Dick a friend of your lad’s?” + 

For an instant Mr. Copperdock made no reply. His face grew even redder than usual, and he picked with his fingers at the arms of his chair. Mr. Ludgrove, recognising the symptoms, knew that at last he was approaching the point of this late visit. He walked across the room, sat down in the chair on the opposite side of the fire, and waited. + 

“Old Ben Colburn’s dead,” blurted out the tobacconist at last, as though the words had been torn from his lips. + 

Mr. Ludgrove raised his eyebrows, “Indeed?” he murmured. “Rather a sudden end, surely? I was in the shop on Friday, talking to Dick, and he said nothing of his father being ill.” + 

“No, he wouldn’t,” said Mr. Copperdock grimly, “He wasn’t taken ill until about two o’clock yesterday afternoon, and he was dead by teatime.” + 

“The usual story in such cases, I suppose?” suggested Mr. Ludgrove. “A diseased heart, and a sudden attack ending fatally?” + 

“Worse than that,” replied Mr. Copperdock slowly. Then suddenly he raised his eyes and looked fixedly at his host. “What do you know about young Dick?” he asked. + 

It was the herbalist’s turn to hesitate, “I might reply that I am a customer of his,” he said at last. “It would be the truth, but not the whole truth. To you, I do not mind admitting in the strictest confidence that he has several times come to me for advice. You will forgive me if I am unable to tell you anything further.” + 

Mr. Copperdock nodded. It was well known that Mr. Ludgrove had never divulged even a hint of the curious stories which had been told him in hesitating whispers in the privacy of this very room. It was the certain knowledge that this was so which gave so many of his clients the courage to confess to him their most secret troubles. + 

“Well, put it this way,” said Mr. Copperdock. “You know that young Dick and his father didn’t hit it off quite, don’t you?” + 

“I may as well confess to that knowledge, since neither of them have made any secret of the fact,” replied Mr. Ludgrove. + 

“Old Ben was a bit of a character in his way,” continued Mr. Copperdock. “He used to drop in sometimes at the Cambridge Arms, and I got to know him quite well, in an offhand sort of way. He had the idea that he was the only man in London who could bake bread, and he often used to tell me that he spent all day and half the night in the bakehouse. He said it was the finest one of its size anywhere, and he used to take me round and look at it sometimes. I couldn’t see anything wonderful about it, but that don’t matter. Ever been there yourself?” + 

“Never into the bakehouse. I have been into the shop at least twice a week for the last four years,” replied Mr. Ludgrove. + 

“Well, the bakehouse is away behind, you go up a long passage from the shop to get to it. Old Ben spent most of his time in the bakehouse, leaving the shop to the lad. But he was a suspicious old cove, and he always had it in his mind that Dick was trying to make a bit out of the business. Couldn’t blame him if he had, the old man kept him short enough. But Dick hadn’t much chance. There’s a cash register in the shop, through which every penny of the takings has to pass.” + 

Mr. Ludgrove nodded. “I know, I’ve often noticed it,” he agreed. + 

“Every afternoon between two and three, when he’d had his dinner, old Ben used to come into the shop and sit at the cash register, checking the takings. And he always smoked a pipe while he was doing it. Queer thing he never smoked in the bakehouse, only just this one pipe in the day. He would smoke it through, then refill it and put it on a shelf in the corner of the shop, ready for the next day. I suppose he done the same thing every day for a dozen years or more. Now, you remember that Friday was poor Jim Tovey’s funeral?” + 

“I do,” replied Mr. Ludgrove. “You remember that I came in to see you that same evening.” + 

“So you did. Well, while I was out, Old Ben comes round to my place to buy a pipe. He only kept one going at a time, and when the old one cracked he bought a new one. Always came to me for them, he did. Ted sold him one of the kind he always has, and out he goes. + 

“Mind you, this is what Ted tells me. The rest of the story, Ted told me last night, after I got back from the Cambridge Arms. Seems young Dick had been in when I was over there and told him all about it. Old Ben goes back to his place, fills his new pipe, and puts it on the shelf ready for his usual smoke on Saturday afternoon. Dick swears nobody touched it in the meantime. The old man was very fussy about his pipe, and it was always left alone. + 

“On Saturday, yesterday, that is, Ben comes back from his dinner a little after two, and the first thing he does is to pick up his pipe and light it. All at once he takes it out of his mouth and cusses. Dick asks him what’s the matter, and he says that the mouthpiece is rough and that he’s scratched his tongue on it. They have a look at the pipe together, and the old man finds a tiny splinter of glass stuck to the mouthpiece. He scrapes it off with a knife, lights his pipe again, and Dick goes out to get his dinner, same as he always does when the old man comes into the shop.” + 

Mr. Copperdock paused, and the herbalist, who had been listening attentively, took the opportunity of putting in a question. “Mrs. Colburn has been dead some little time, I believe?” + 

“Yes, ten years or more, if my memory serves me right. Dick and his father lived over the shop, with a charwoman to come in and do for them in the morning. When Dick comes back from his dinner, a little before three, the old man was still sitting at the cash register, and Dick sees at once that something is wrong. The old chap can hardly speak, says his tongue’s very swollen, and that he feels stiff all over. Dick slips out sharp and gets a doctor, and between them they gets Ben upstairs to bed. Doctor, he did what he could, but it wasn’t any use, and poor old Ben dies in two or three hours.” + 

“What an extraordinary thing!” exclaimed Mr. Ludgrove. + 

“That’s what the doctor said. He wanted to find the bit of glass which had scratched old Ben’s tongue, and he and Dick had a hunt for it, but it must have fallen on the floor of the shop. It was only a tiny piece, anyway. Of course they never found it, but the doctor says there must have been some extraordinary powerful poison on it, and I can’t see how a bit of glass like that could get stuck on the mouthpiece of a pipe accidental like.” + 

“Of course, nicotine acts as a poison if it is injected into the blood,” suggested Mr. Ludgrove. “It is just possible that the fragment of glass was harmless enough, but that the nicotine in the pipe found its way into the scratch.” But Mr. Copperdock shook his head. “It was a new pipe, what hadn’t ever been smoked before,” he replied. “Bought at my place the day before, as I told you.” + 

“Did your son examine the pipe before he gave it to Mr. Colburn?” asked Mr. Ludgrove quickly. + 

“That’s just what I asked him, and he says he can’t be sure. Of course, he didn’t see any glass or he’d have given old Ben another pipe. We gets them in dozens, each pipe twisted up in a bit of paper. Ted took the first that came out of the box, tore the paper off it, and handed it to Ben, who put it straight into his pocket. I’ve looked at the rest of the box since, and there’s no sign of any glass on any of them.” + 

“You say that Mr. Colburn filled the pipe as soon as he got home, and put it in the usual place,” said Mr. Ludgrove slowly. “It was lying there until two o’clock on Saturday. Anybody might have tampered with it in the meanwhile. The cash register, and I suppose the shelf where the pipe was kept, is within easy reach of anybody coming into the shop.” + 

“I’m afraid that won’t work,” replied Mr. Copperdock, shaking his head. “There’s not one in a thousand as goes into the shop that know’s the pipe’s there. You didn’t yourself till I told you just now, yet you say you’re a regular customer. No, if that pipe was tampered with, it was somebody on the other side of the counter what did it.” + 

“Then you are quite convinced in your own mind that Mr. Colburn was deliberately murdered?” suggested Mr. Ludgrove. “But what motive could anybody have for desiring his death?” + 

“What motive had anybody for murdering poor old Jim Tovey last week?” retorted Mr. Copperdock. “There’s only one person who gains anything by Ben’s death, and who that is you know as well as I do!” + 

“I can’t help thinking that you are taking too grave a view of the case,” said Mr. Ludgrove. “I admit that it is difficult to account for a piece of poisoned glass finding its way on to Mr. Colburn’s pipe by accident, but murder is a very grave charge, and there is hardly sufficient evidence at the moment to warrant it.” + 

Mr. Copperdock braced himself in his chair as though to give himself the strength to utter his next words. “Ludgrove,” he said impressively. “I know poor Ben Colburn was murdered, same as I know Jim Tovey was murdered. And it was the same hand as struck them both down.” + 

Mr. Ludgrove sank slowly back into his chair, and a faint smile twinkled for a moment at the corner of his lips. But before he could make any remark, Mr. Copperdock, who had been watching him closely, continued. + 

“It’s all very well for you to laugh, but neither you nor any other living soul knows what I do. Now just you listen, and see if I’m not right. Last Wednesday, I was in the Cambridge Arms in the evening, same as I almost always am. In comes old Ben Colburn, and comes straight over to me. He puts his hand in his pocket, and slaps an ordinary bone counter down on the table in front of me. ‘Now then, Sam, what’s the meaning of this little joke?’ he says. + 

“I looks at the counter and I looks at him. ‘What do you mean, what’s the joke?’ I says. + 

“Why, didn’t you send me this?” he says, suspicious like. + 

“I told him I hadn’t, and then he says that it came to him by post that morning, wrapped up in a bit of blank paper. ‘I made sure it was one of your jokes, Sam,’ he says. I picked up the counter and looked at it. On one side it had the figure II drawn on it in red ink. ‘What does it mean?’ I said. ‘That’s just what I want to know,’ says Ben. ‘You shove it in your pocket, Sam, you’re better at finding out that sort of thing than I am.’ So I shoved it in my pocket, and here it is.” + 

Mr. Ludgrove took the counter which the tobacconist handed him and looked at it curiously. It was just as Mr. Copperdock had described it, a white bone counter, about the size of a halfpenny, with the Roman numeral II, carefully traced upon it in red ink. + 

“I never thought about it again, until this afternoon,” continued Mr. Copperdock. “Naturally I didn’t connect it with Ben’s death. Why should I? But today, being Sunday, I went round to see Mrs. Tovey neighbour-like. You see, it was her first Sunday after Jim’s death, and I thought that she and Ivy might get brooding over things.” + 

Mr. Copperdock looked anxiously at his friend as he spoke, but the expression on the herbalist’s face was one of polite interest only. “Very thoughtful of you, I’m sure,” he murmured. “I hope that Mrs. Tovey is not taking her husband’s death too much to heart.” + 

“She’s bearing up as well as can be expected,” replied Mr. Copperdock. “She and I got to talking about Jim, and wondering whoever it could have been that murdered him. She was telling me all about the telephone call, and she went on to say that this was the second queer thing that happened just before he died. Naturally I asked her what the first was, and she told me that on the Friday morning before his death, a typewritten envelope came addressed to him. He opened it, and all there was inside was a white counter with the number I drawn on it in red ink. Now what do you make of that?” + 

Mr. Ludgrove sat silent for a moment under his friend’s triumphant gaze, a thoughtful frown upon his face. “This is most extraordinary,” he said at last. “If your facts are correct⁠—not that I doubt them for a moment, but I know how fatally easy it is to find presages after the event⁠—it means that both Mr. Tovey and Mr. Colburn received, a couple of days or so before their respective deaths, a white counter bearing a numeral in red ink. It is almost certain that both counters were sent by the same person, and, if they were intended as a warning, we may infer, as you said, that both men were murdered by the same hand.” + 

Mr. Copperdock nodded rather impatiently. “Just what I told you, all along,” he said. + 

“But, my dear sir, look at the difficulties which that theory entails,” objected Mr. Ludgrove. “We are agreed that it is impossible to think of any motive for the murder of Mr. Tovey, and I at least am inclined to say the same regarding the murder of Mr. Colburn. Yet now we are faced with the problem of finding a man who had a motive for murdering both of them. By the way, do you happen to know if they were ever associated in any way?” + 

“Never!” replied Mr. Copperdock emphatically. “Although they’d both lived in these parts most of their lives, I don’t suppose they even knew one another by sight.” + 

“The fact that they had nothing in common makes it all the more puzzling,” said Mr. Ludgrove reflectively. “But perhaps you have thought of a way out of the difficulty?” + 

A cloud came over Mr. Copperdock’s naturally cheerful face, and there was a marked hesitancy in his tone as he replied. “Aye, I have thought of something, and it’s that that’s been worrying me. Mind, I don’t believe it myself, but I’m in mortal fear lest someone else should see it too.” + 

“I think I can guess what you mean,” said Mr. Ludgrove gently. “I know as well as you do that it isn’t true, but we’re both of us too well aware of the mischief that can be caused by whispering tongues to treat it as unimportant. You mean that young Colburn was not on good terms with his father, that he and your son are great friends, and that your son sold Mr. Colburn the pipe which is supposed to have been the agency of his death.” + 

“I do mean that,” replied Mr. Copperdock deliberately. “I mean too that Ted is very sweet on Ivy Tovey, and that poor old Jim wasn’t very keen on the idea. Now you see the sort of lying whispers that might get about if all this was known. And I’m blest if I see what I can do about it.” + 

“I think you told me that you had some conversation with a Police Inspector last week on the subject of Mr. Tovey’s murder?” suggested Mr. Ludgrove. + 

“That’s right,” replied Mr. Copperdock. “Very decent sort of chap he was, too. What about him?” + 

“Do you know where and how to get hold of him?” + 

“Yes, he left me his card. I’ve got it at home somewhere.” + 

“Well, Mr. Copperdock, if you will take my advice you will go and see him, and tell him everything you know, as you have just told me. It’s all bound to come out, sooner or later, and if you have already informed the police, your position will be all the stronger. Don’t you agree?” + 

“Yes, I suppose I do,” replied Mr. Copperdock reluctantly. “But it seems terrible, like giving evidence against my own flesh and blood.” + 

“On the contrary, you will be doing the very best for your son. A frank statement of facts is always the best defence of the innocent. Tell your friend the Inspector everything, not forgetting the curious incident of the numbered discs. He will know better than I do what advice to give you in the matter. And, if you feel that I can be of the slightest assistance to you, do not hesitate to come to me at once.” + 

After some further discussion Mr. Copperdock agreed to follow his friend’s advice, and, after a parting drink, went home, somewhat comforted. The herbalist, having locked the door behind him, returned to the interrupted classification of his plants. But, from the slight frown which passed across his face from time to time, one might have guessed that he was thinking more of his conversation with Mr. Copperdock than of the specimens before him. + 

Inspector Whyland + 

The death of Mr. Colburn, following so closely upon that of Mr. Tovey, caused a distinct sensation in Praed Street and its immediate neighbourhood. Suspicion was, so to speak, in the air, and anybody known to have been intimate with either of the dead men was looked at askance, and became the subject of whispered comment when their backs were turned. Not that this floating suspicion actually settled down upon any individual head. But Praed Street discovered an uneasy feeling that the two inexplicable deaths of which it had been the scene indicated that it harboured a murderer. + 

On the Wednesday morning following Mr. Ludgrove’s visit to Suffolk, a man walked into his shop and rapped upon the counter. The herbalist emerged from the back room at the summons, and, as was his habit, glanced gravely at his customer. He saw before him a youngish man, immaculately dressed, who immediately turned towards him interrogatively. “Mr. Ludgrove?” he said. + 

The herbalist bowed. “That is my name,” he replied. “Can I be of any service to you?” + 

The stranger placed a card upon the counter, with an apologetic gesture. “I’m Detective Inspector Whyland, attached to the F Division,” he said. “And if you could spare me a few minutes, I should be very grateful. I’m awfully sorry to have to intrude in business hours.” + 

“Oh, pray do not apologize, I am rarely very busy in the morning,” replied Mr. Ludgrove courteously. “Perhaps you would not mind coming through this door. We shall be able to talk more privately.” + 

Inspector Whyland accepted the invitation, and sat down in the chair offered him. Mr. Ludgrove having pressed him to smoke, sat down in the opposite chair, and looked at him enquiringly. + 

“I daresay that you can guess what I have come to talk about,” began the Inspector, with a pleasant smile. “I may as well confess at once that I want your help. We policemen are not the supermen which some people think we ought to be, and most of us are only too anxious to ask for assistance wherever we are likely to get it. And I personally am under a debt of gratitude to you for persuading Mr. Copperdock to unburden himself to me.” + 

Mr. Ludgrove smiled. “Oh, he told you, did he?” he replied. “It was much the best thing he could do. I hope he convinced you, as he certainly did me, that both he and his son were completely innocent of any knowledge of these queer happenings.” + 

It was the Inspector’s turn to smile. “He did. I don’t think that Mr. Copperdock is of the stuff of which deliberate murderers are made, and from what I have seen of the son, I fancy the same applies to him. But may I, since you appear to be pretty intimate with Mr. Copperdock, ask you one or two questions about him? You needn’t answer them unless you like.” + 

“Most certainly I will answer them to the best of my ability,” replied Mr. Ludgrove gravely. + 

“Thank you. In the first place, can you suggest why he is so obviously confused when any reference is made to the Tovey family? I understand that his son and Tovey’s daughter are⁠—well, great friends, but that could hardly account for his manner.” + 

Again Mr. Ludgrove smiled, this time with genuine amusement. “My dear sir, haven’t you guessed the reason? I did, some days ago. Mrs. Tovey is, I believe, a very charming woman, and by no means too old to consider the possibility of marrying again. Mind you, Mr. Copperdock is convinced that his secret is safely locked in his own breast, and I should forfeit his friendship if he had any inkling that I shared it.” + 

Inspector Whyland laughed with an obvious air of relief. “Oh, that’s the way the wind blows, is it?” he said. “You may rest assured that I shall be the soul of discretion. I had an uncomfortable feeling that he knew something that he did not care to tell me. Now, if I may trouble you with another question, what do you know of the relations between the Copperdocks and the Colburns?” + 

This time Mr. Ludgrove shook his head. “Nothing at first hand,” he replied, “only what Mr. Copperdock has told me, which is doubtless the same as what he told you.” + 

“You will forgive my pressing the point, Mr. Ludgrove,” persisted the Inspector. “But I gather from Mr. Copperdock’s remarks that you are to some extent in the confidence of young Colburn.” + 

Mr. Ludgrove looked him straight in the face. “Inspector Whyland,” he said gravely, “I should like you fully to realize my position. Many of the inhabitants of this part of London believe, rightly or wrongly, that my experience of the world is greater than theirs. Consequently they frequently seek my advice upon the most personal and intimate matters. I have been the recipient of many confidences, which it has been my invariable rule never to mention to a third person. Dick Colburn has consulted me more than once, and it is only because I believe it to be in his interest that I am prepared to break my rule in his case.” + 

“I fully appreciate your motives, Mr. Ludgrove,” replied the Inspector. “I will make no use of anything you care to tell me without your permission.” + 

“Thank you, Inspector,” said Mr. Ludgrove simply. “Dick Colburn informed me some months ago that he found it very difficult to get on with his father. His chief complaint was that although he performed the whole work of the shop, his father treated him as though he were still a child, and refused to allow him any share of the profits of the business. I advised him to persuade his father to admit him into partnership, and if he proved obdurate, to announce his intention of seeking work elsewhere. I think it is only fair to add that the lad came to see me yesterday evening, in order to assure me that he had no share in his father’s death.” + 

Inspector Whyland shrugged his shoulders. “In spite of appearances I am inclined to believe him,” he replied wearily. “Frankly, Mr. Ludgrove, I am completely at a loss. As you know, the jury at the inquest on Mr. Colburn returned an open verdict, but I think there can be very little doubt that he was deliberately murdered. We can rule out suicide, people don’t take such elaborate steps to kill themselves. And the circumstances seem too remarkable to be accidental, which brings us back to Mr. Copperdock and his remarkable story of the numbered discs. What do you make of that, Mr. Ludgrove?” + 

“Very little, although I have puzzled over it a good deal, since I heard it,” replied the herbalist. “Of course, it is possible that the receipt by Mr. Colburn of the one you have doubtless seen had nothing whatever to do with his death, and that the combined imagination of Mr. Copperdock and Mrs. Tovey evolved the first out of something equally harmless. Mrs. Tovey is the only person who claims to have seen it, I understand.” + 

“And yet her accounts of it are remarkably consistent,” said the Inspector. “I went to see her and introduced the subject as tactfully as I could. She described the incident in almost exactly the same words as Mr. Copperdock used, and added that her husband, attaching no importance to it, threw counter, envelope and all into the fire. Her daughter, Ivy, was not present at the time. And yet, if we apply the obvious deduction to the sending of these numbered counters, what possible motive could anybody have for murdering two peaceful and elderly tradesmen, apparently strangers to one another, or, still more, for warning them first? It only adds another problem to this extraordinary business.” + 

“Are you going to make the story of the numbered counters public?” asked Mr. Ludgrove. + 

“One of my reasons for coming to see you was to ask you to say nothing about it,” replied the Inspector. “We have decided that there is nothing to be gained by letting it be known. Bone counters of this size are very common, and we are not likely to learn where these particular ones originated. On the other hand, the minute the story becomes known, there will be an epidemic of counters bearing the number III in red ink. The Post Office will be overwhelmed by envelopes containing them, and every one of the recipients will come clamouring to us for protection. You may think this is an exaggeration. But you have no idea of the effect of crime upon some people’s mentality.” + 

Mr. Ludgrove laughed softly. “I think I have,” he replied. “I haven’t been a sort of confidential adviser to the poorer classes all these years for nothing. Nearly everybody who has been in this room for the last week has had definite knowledge of the murderer of Mr. Tovey, for which knowledge they seem to think it is my duty to pay a large sum of money. When I tell them to go to the police their enthusiasm evaporates with amazing rapidity. And since you people offered a reward for Wal Snyder’s sailor, the whole neighbourhood appears to have seen him.” + 

“So I imagine,” said the Inspector. “There is usually a queue at the police station waiting to claim the reward. But what could we do? I confess I was very sceptical about the existence of this man; but I’ve bullied the wretched Wal half a dozen times, drunk and sober, and he sticks to the story. ‘S’welp me, it’s as true as I’m standing here,’ he says, ‘a big tall bloke, dressed like a sailor, with a black beard, an ugly gash on his cheek, and a woollen cap.’ We had no option but to advertise for such a man.” + 

“Well, I hope you’ll find him, Inspector,” remarked Mr. Ludgrove. “But you’ll forgive my saying that I have grave doubts about it. Even Mr. Copperdock, who spends a large part of his time watching the people who pass his shop, has never seen anybody answering his description. And again I find it difficult to imagine a black-bearded sailor with a scar having a grudge against Mr. Tovey. Besides, he doesn’t sound the sort of person to deliver numbered counters in typewritten envelopes.” + 

The Inspector rose from his chair with a smile. “It is a maxim of the police never to admit defeat,” he said. “I am immensely obliged to you for your courtesy, Mr. Ludgrove. Perhaps if you hear of anything which has any possible bearing on the case you will send for me?” + 

The herbalist willingly consenting to this, Inspector Whyland took his departure. He had scarcely been gone five minutes before Mr. Ludgrove, who had returned to the back room, heard Mr. Copperdock’s voice in the shop. + 

“Come in, Mr. Copperdock,” called the herbalist genially. + 

The curtain was furtively drawn aside, and Mr. Copperdock came in, a look of deep anxiety upon his face. “That was Inspector Whyland in here just now, wasn’t it?” he enquired. + 

“It was,” replied Mr. Ludgrove. “We had quite a long chat.” Then, with a sudden change of manner, he laid his hand on his friend’s shoulder. “Look here, Mr. Copperdock,” he said earnestly, “get out of your head all idea that the police have any suspicions of you or your son. I can assure you that they have not, and that your straightforwardness in going to them and telling them all you know has impressed them greatly in your favour.” + 

“Thank God for that!” exclaimed the tobacconist fervently. “I’ve been terrible worried these last few days. I’ve laid awake at nights and puzzled over it all again and again. I’ve even given up going to the Cambridge Arms of an evening. I sort of feel that the fellows there don’t talk to me quite in the way they did.” + 

“Oh, nonsense!” exclaimed Mr. Ludgrove. “You mustn’t let this prey on your mind. We all know as well as you do that you have done nothing to reproach yourself with. Now I must ask you to excuse me, for I think I hear a customer in the shop.” + 

As the days went by, and no further developments took place, Mr. Copperdock’s face regained its accustomed cheerfulness, and he resumed his visits to the Cambridge Arms. The newspapers found fresh sensations with which to fill their columns, and even Praed Street, in the stimulus to trade furnished by the approach of Christmas, began to forget the strange occurrences of which it had been the scene. Ted Copperdock developed a new smartness of appearance and carefulness of speech, no doubt the results of his frequent enjoyment of Ivy’s company. It was only natural that on Sundays, when the young people were out at the Pictures, Mr. Copperdock should walk over to Lisson Grove to console Mrs. Tovey’s loneliness. Only Mr. Ludgrove, as he regretfully explained to his friends, found himself too busy to spend one of those weekends in the country which he so much enjoyed. + 

Indeed, it was not until the weekend before Christmas that he found an opportunity for leaving the shop for more than an hour or two at a time. He confided his intentions to Mr. Copperdock on the Friday. “I have just heard that a plant of which I have long been in search is to be discovered in a spot not far from Wokingham,” he said. “The nearest Inn appears to be at a village called Penderworth. I propose to go there tomorrow and spend the afternoon and Sunday searching for the herb. As I mean to come up by an early train on Monday, I have taken the liberty of telling Mrs. Cooper, who comes in every weekday to tidy my place up, that I have left the key with you. I suppose that it is no use asking you to come with me?” + 

Mr. Copperdock fidgeted uncomfortably. “Leave the key by all means,” he replied heartily. “I’ll look after it for you. Sorry I can’t come with you, but you see about Christmas time I⁠—we⁠—there’s a lot of folk comes to the shop and I can’t very well leave Ted alone.” + 

“I quite understand,” said Mr. Ludgrove, without a smile. “I shall leave Waterloo at 1:30 tomorrow, and reach that station again just before ten on Monday. If Mrs. Cooper has finished before then, she will bring you back the key.” + 

His arrangements thus made, the herbalist closed his shop at noon on Saturday, and, equipped with a suitcase which he always took with him, took the Tube to Waterloo station. On arrival at Wokingham, he hired a car to drive him to the Cross Keys at Penderworth. It was after three o’clock when he arrived, and after securing a room, writing his name and address in the register, and arranging for some supper to be ready for him at half-past seven, he went out again immediately, a haversack slung over his shoulder, and an ordnance map in his hand. + 

It was after seven when he returned, his boots covered with mud, and his haversack bulging with a miscellaneous collection of plants. A fine drizzle had come on during the afternoon, and he was very wet. But trifles like these never dampened his spirits, and he made remarkable headway with the cold beef and pickles produced for his delectation. His meal over, he made his way to the smoking-room fire, and, spreading a newspaper on the table, began to examine the contents of his haversack. + 

The rain, which by this time was falling steadily, seemed to have kept the regular customers of the Cross Keys at home. The smoking-room was empty, but for Mr. Ludgrove; and the landlord, after leaning idly against the bar at one end of the room, and staring inquisitively at his solitary guest, could restrain his curiosity no longer. Lifting the flap, he walked across the room, with the ostensible object of making up the fire. + 

Mr. Ludgrove looked up at his approach. “Good evening,” he said pleasantly. + 

“Good evening, sir,” replied the landlord, glancing at the plants laid out on the newspaper. “You’ve been having a walk round the country this afternoon, then.” + 

“Yes, and a very pleasant country it is for one of my interests,” said Mr. Ludgrove. “I have secured several very interesting specimens, and I hope to find others tomorrow.” + 

“Ah!” exclaimed the landlord. “Flowers and that aren’t much in my line. I’ve got a bit of garden, but it’s mostly vegetables. Pity the rain came on like it did.” + 

“Oh, I don’t mind the rain,” replied Mr. Ludgrove. “Walking about the country as I do, I am compelled to take the weather as it comes. I can only get away from London during the weekends.” + 

“I see you come from London by what you wrote in the book,” said the landlord slowly. “It’s Praed Street you lives in, isn’t it?” + 

Mr. Ludgrove smiled. The eagerness in the landlord’s voice was very transparent. “Won’t you sit down and have a drink with me?” he said. “Yes, I live in Praed Street. Perhaps you saw in the paper that we had some very unusual happenings there a few weeks ago.” + 

“I did, sir, and it was seeing you came from there made me think of them,” replied the landlord. He went back to the bar and got the drinks, which he brought to the fire. It immediately appeared that his interest in crime, as reported in the newspapers, was at least as keen as that of the late Mr. Tovey. But never before had it been his fortune to meet one who had personally known the victims of two unsolved murders. + 

“It’s a queer thing,” he said, “but a couple of days or so before this Mr. Tovey was murdered, I was polishing the glasses behind the bar in this very room, when I looked out of the window and sees a sailor, big chap he was, walking past. I didn’t rightly catch sight of his face, but he was carrying a bag and going towards London. Looked as if he was on the tramp, I thought. I never thought about it again till I sees the police advertising for this sailor chap, then, of course, I tells the constable at the Police Station up the village. I never heard whether they traced him or not.” + 

“You didn’t notice if he had a black beard or a scar?” suggested Mr. Ludgrove mildly. + 

“No, I didn’t see his face,” replied the landlord, with an air of a man brushing aside an irrelevant detail. “But that’s just like the police. You give ’em a bit of valuable information, and they hardly ever says thank you for it.” + 

The landlord, warming to his work, and finding Mr. Ludgrove an excellent listener, developed theory after theory, each more farfetched than the last. It was not until the clock pointed to closing time, that he rose from his chair with evident reluctance. “You mark my words, there’s more in it than meets the eye,” he said darkly, as he leant over the table, “as my old dad, what kept this house afore I did, used to say, if there’s anything you can’t rightly understand, there’s bound to be a woman in it. Look at the things what you sees in the papers every week. How do you know that these two poor chaps as were killed wasn’t both running after the same woman? And if she was married couldn’t ’er ’usband tell you something about why they was murdered? You think it over, sir, when you gets back to London.” + 

And the landlord, nodding his head with an air of superlative wisdom, disappeared in the direction of the taproom. By the time he returned, Mr. Ludgrove had collected his belongings and retired to bed. + 

By the following morning the rain had ceased, and Mr. Ludgrove was enabled to pursue his explorations in comfort. He went out directly after breakfast and returned to the Inn in time for lunch. In the afternoon he followed a different direction, arriving back shortly after dark. When he repaired to the smoking-room after supper, he found that his fame as a personal acquaintance of the murdered men had preceded him. Mr. Ludgrove was before all things a student of human nature, and he seemed almost to enjoy taking part with the leading men of Penderworth in an interminable discussion of the unsolved crimes. Perhaps he reflected that the looker-on sees most of the game, and that these men, viewing the circumstances from a distance, might have hit upon some point in the evidence which had escaped the observers on the spot. + 

At all events, he went to bed on Sunday night with the remark that he had thoroughly enjoyed his visit to Penderworth. A car had been ordered to take him to Wokingham station early on Monday morning. His first act upon reaching the platform was to buy a paper and open it. Across the top of the centre page lay spread the ominous headline: + 

Another tragedy in Praed Street + 

VI + 

A Middle-Aged Poet + 

Mr. Richard Pargent’s public was a very limited one. A few lines of type, of unequal length, would appear from time to time in one of the ultra-artistic magazines, and would be hailed by critics of the new school as yet another deadly blow at the shackles which have hitherto fettered the feet of the muse of poetry. The general public found them incomprehensible, which was perhaps a fortunate circumstance for Mr. Pargent’s reputation. + 

But, in spite of Mr. Pargent’s extreme literary modernity, his surroundings and circumstances were typically mid-Victorian. His age was between fifty and sixty, and he lived with his sister Clara in a tall, narrow house in Bavaria Square, Bayswater. It was, as a matter of fact, the house in which he and his two sisters had been born. On their parents’ death he and Miss Clara Pargent had elected to remain where they were and keep house together. Miss Margaret, younger and more adventurous, had taken unto herself a companion⁠—of the female sex⁠—and migrated to a house in the little town of West Laverhurst, in Wiltshire. + 

It will be gathered from this that the Pargent family were not dependent upon Mr. Richard Pargent’s literary earnings. Each member of it was comparatively well off, and lived according to the standards of mid-Victorian comfort. In their own phrase, they knew quite a number of nice people, and sometimes they found it difficult to make time in which to perform all their social duties. As a consequence, they had little opportunity left for doing anything useful. + 

Although many years had elapsed since Miss Margaret had shaken the dust of Bayswater off her feet and retired to the intellectual wilderness of West Laverhurst, her brother and sister had never completely recovered from the shock of such a revolutionary proceeding. Never before, within the memory of man, had any member of the Pargent family done anything but what was expected of them. And even now, when any of their friends asked after Miss Margaret, they replied with an almost imperceptible hesitation, with the apologetic smile we adopt when speaking of anyone who exhibits such remarkable eccentricity. + 

Not that Miss Margaret’s departure had entirely broken the bonds which united the family. She and Miss Clara exchanged letters every day, although it must exceed the comprehension of ordinary mortals what they found to write about. Further than this, West Laverhurst was the object of a regular fortnightly pilgrimage on the part of Richard Pargent. Every other Saturday he caught the 10:45 at Paddington, which reached West Laverhurst at 12:25, giving him ample time to lunch with his sister and catch the 3:10 up, which deposited him at Paddington at 4:55. Miss Clara always had tea ready for him in the drawing-room in Bavaria Square. A No. 15 bus from Paddington took him almost to his door. + 

The Saturday before Christmas happened to be the occasion for one of these fortnightly visits. It was usual for Mr. Pargent to walk the short half mile which separated West Laverhurst from his sister’s house, but, the afternoon being wet and Mr. Pargent very careful of his health, he asked Miss Margaret to requisition a car to drive him to the station. He arrived there in plenty of time, and in due course the 3:10 came in punctually. Mr. Pargent took a corner seat in a first-class non-smoking carriage, and immediately became immersed in a book which he had brought with him for the purpose of reading in the train. He inwardly congratulated himself upon having secured a seat in an empty carriage. + 

The 3:10 up from West Laverhurst stops twice before reaching Reading, and then runs fast up to London. The stop at Reading is a somewhat long one, owing to the fact that tickets are collected there. On this particular afternoon, the train had run into the station a minute or two before time, and the stop was even longer than usual, giving a tall man in a rather tight-fitting overcoat ample time to walk leisurely the whole length of the train and select an empty first-class smoking carriage close to the engine. The train started at last, Mr. Pargent being left in undisputed possession of his compartment. + 

The train arrived at Paddington punctually at five minutes to five. Mr. Pargent had observed that the rain was falling more heavily than ever, but, from his long experience of Paddington station, he knew how to reach the stopping place of the No. 15 bus, keeping under cover nearly all the way. He had only to follow the subway which leads to the Underground booking-office, and then climb the stairway which leads into Praed Street. The No. 15 bus stops nearly opposite on the further side of the street. + 

The passenger who had got in at Reading seemed to know his way about as well as did Mr. Pargent. This man, who somehow vaguely suggested a retired ship’s officer, had an iron-grey beard and a curious patch of crimson, such as is popularly known as a port-wine mark, on his left cheek. He walked slowly down the subway, so slowly that Mr. Pargent overtook him before he reached the foot of the stairway. The two ascended it together, only a few steps separating them, Mr. Pargent leading. + 

The mouth of the stairway was blocked, as it so often is in wet weather, by a knot of people unfurling their umbrellas and waiting for an interval in the traffic to dash across to the refuge in the middle of the road. Mr. Pargent unfolded his umbrella like the rest, and seizing his opportunity, ran for the island. The interval was a narrow one; an almost unceasing stream of buses and taxis was pouring down Praed Street. Only two or three followed Mr. Pargent’s example, among them the Reading passenger. In the blinding rain and the flurry of the traffic nobody noticed a swift movement of the latter’s arm, nor did they watch him as he left the refuge immediately and gained the far side of the road. + 

The clock above the entrance of the station showed it to be exactly five o’clock. The Reading passenger glanced at it, walked swiftly a few yards westward up Praed Street, then, seizing his opportunity, crossed the road again. This brought him to the slope leading to the departure platform of Paddington station. He hurried through the booking office on to No. 1 platform, at which stood the 5:50 train for Bristol, which stops for the first time at Reading. He showed the ticket collector a third-class single ticket for Reading, and the man hastily opened a carriage door and pushed him in. “Near shave that, sir!” he remarked. + 

The passenger was far too short of breath to do anything but nod his head in reply. He sank down exhausted upon the seat as the guard blew his whistle and the train drew out of the station. There were only two men beside himself in the carriage, and they, with true British indifference, took no further notice of him. The train had nearly reached Reading when he walked down the corridor to the lavatory. He did not return to the carriage, but stepped straight from the corridor to the platform as the train came to rest. He mingled unnoticed with the stream passing the barriers. He noticed that the hands of the clock pointed to ten minutes to six. + 

Meanwhile Mr. Pargent had stood for an instant upon the refuge in the middle of Praed Street, a puzzled expression on his face. An approaching taxi-driver noticed his swaying form and swerved sharply, just in time to avoid him as he crashed forward into the roadway. The taxi-driver’s action caused a sudden check to the traffic, and for an instant there was a chaos of skidding vehicles, screeching brakes, and blasphemous language. Then the nearest drivers jumped from their seats and clustered round the prone form. A majestic policeman, setting a calm and undeviating course through the tumult, knelt down and turned the body over. Mr. Pargent was dead. + 

The newspaper which Mr. Ludgrove bought at Wokingham station and read carefully during his journey to Waterloo contained nothing more than a bare statement that the famous poet, Richard Pargent, had fallen dead in Praed Street, and that, upon the body being conveyed to the mortuary, a blade was found in it, with the point entering the heart. Round these facts a formidable structure of conjecture and reminiscence was built up. There was an obituary notice, in which Mr. Pargent’s Christian names and the titles of his published works were incorrectly stated. There was a résumé of the case of Mr. Tovey, and a photograph of Praed Street, with heavy black crosses marking the places where the murders had taken place. Finally there was a leading article, in which the responsibility for the murders was ingeniously fixed upon the Government, which in consequence came in for severe criticism. In fact, the murder of Mr. Pargent was evidently the topic of the day. + 

Mr. Ludgrove sat with his haversack beside him on the carriage seat, even his beloved plants unheeded. He read every bit of the paper over and over again, seeking for some clue which might account for the crime. The description ended with the words “the police are, however, in possession of a clue, the nature of which they are not at present prepared to divulge, but which, they are confident, will lead to startling developments in the near future.” Mr. Ludgrove smiled rather cynically as he read them. They seemed to him to have a somewhat familiar ring. + 

He had the paper in his hand as he walked into Mr. Copperdock’s shop to get his key, and his friend caught sight of it. “So you’ve seen the news, then?” he said excitedly. + 

Mr. Ludgrove nodded gravely. “I have been reading the account as I came up in the train,” he replied. + 

“We didn’t know a thing about it till eight o’clock on Saturday evening,” continued Mr. Copperdock eagerly. “I was just going across to the Cambridge Arms when Inspector Whyland came in and asked me casual-like what I’d been doing all the afternoon. As a matter of fact neither Ted nor I had hardly left the shop, and so I told him. It wasn’t till then that he let on that three hours before a gentleman had been murdered not a hundred yards away, exactly the same as poor Tovey. Then I remembered that a customer had told me something about an accident outside Paddington station, but, being busy, I hadn’t taken any heed of it. And, that reminds me, the Inspector left a message for you, asking if you would let him know when you got back. I’ll ring him up from here if you like, I’ve got his number.” + 

“I wish you would, I have no telephone, as you know,” replied Mr. Ludgrove. “Has Mrs. Cooper brought my key back yet?” + 

Mr. Copperdock felt in his pocket and handed the herbalist a Yale key. “She brought it in ten minutes ago. She was terribly upset, and talked about our all being murdered in our beds next. It’s a terrible thing to have happened just before Christmas like this. People will be afraid to go out of doors after dark.” + 

Mr. Ludgrove nodded rather absently, and took the key which his friend offered him. “You’ll let Inspector Whyland know I’m back?” he said, and, without awaiting Mr. Copperdock’s reply, he left the shop, crossed the road, and entered his own premises, a thoughtful frown upon his face. + 

Inspector Whyland lost no time in acting upon Mr. Copperdock’s message. The murder of Mr. Richard Pargent, following so soon upon that of Mr. Tovey, and perpetrated by the same method, had made a great sensation, not only among the public, but, which was far more important to the Inspector, at Headquarters. He had been given a pretty direct hint that unless he could find some clue within the next few days, the case would be taken out of his hands and given to some more capable officer. All the machinery at the disposal of the police had been put into action, but so far without the slightest result. And in Inspector Whyland’s despair it seemed to him that the only hope left of gaining any information was through the herbalist, with his peculiar inner knowledge of the inhabitants of the district. + 

He arrived to find Mr. Ludgrove busily engaged in writing up descriptions of his botanical trophies in a large manuscript book. The herbalist greeted him warmly, and invited him to a seat in the best chair. The two sat for a moment in silence, until the Inspector spoke abruptly. + 

“Look here, Mr. Ludgrove, what do you know about this man who’s been killed?” + 

“Richard Pargent?” replied the herbalist quietly. “I know nothing about him personally. I have seen his name mentioned once or twice as a writer of verse, but I doubt if I should have remembered it had it not been recalled to me by what I read in the papers this morning.” + 

“Do you know anything about this poetry of his?” continued the Inspector. + 

Mr. Ludgrove smiled. “I am no judge of poetry,” he replied. “But I can hardly imagine that it was bad enough to inspire anyone with a desire to murder him.” + 

Inspector Whyland shrugged his shoulders impatiently. “That’s just it!” he exclaimed. “There doesn’t seem to have been anything about the man to provide a motive for his murder. Look here, Mr. Ludgrove, you’re not the sort of man to go round spinning yarns to your friends. I’ll make a bargain with you. You get to know all sorts of things that never come to our ears. Tell me your honest opinion about these murders, and I’ll tell you what we’ve found out so far.” + 

For a moment Mr. Ludgrove made no reply. When at length he spoke it was with a deep note of earnestness in his voice. “I am honoured by your confidence, Inspector. As you have guessed, I have been very much concerned by these murders. I have feared that they would be traced to one or other of my clients, some of whom, I regret to say, have little respect for the law. I know much of the inner history of Praed Street and its neighbourhood, and I regret to say that much of it is almost incredibly sordid. I refer of course to its underworld, and not to its respectable inhabitants, who are greatly in the majority. But of two facts I can assure you. The first is that in all my experience I have never heard of a crime committed by any of the class to which I refer except for some specific purpose, either gain or revenge, and the second is that none of them would resort to murder except perhaps in a sudden access of passion.” + 

The Inspector nodded. “That’s very much my own experience of regular crooks,” he replied. “But you say you’ve thought a lot about this business. Haven’t you any theory of your own?” + 

“The only theory I can form is that the murders are the work of some irresponsible maniac,” said Mr. Ludgrove quietly. + 

“Would an irresponsible maniac have put a piece of poisoned glass on the end of Colburn’s pipe?” countered the Inspector quickly. “No, I am afraid that theory won’t do, Mr. Ludgrove.” + 

“I think it is the only theory which fits in with the assumption that these three men were all murdered by the same hand,” replied the herbalist. + 

“Yet I don’t think you can get away from that assumption,” said Inspector Whyland. “I don’t mind telling you something that worries me a bit, since it’s bound to come out at the inquest. One of the first things we found when we searched Pargent’s pockets in the mortuary was this.” + 

He put his hand in his pocket, then held it out with extended palm toward Mr. Ludgrove. + 

The herbalist leant forward with an exclamation of surprise. “Ah, a white counter with the figure III drawn on it in red ink!” he exclaimed. “Do you know, Inspector, I wondered if anything of the kind had been found. That is really interesting.” + 

“Interesting!” grumbled the Inspector. “Aye, the reporters will find it interesting enough, you may bet. We couldn’t keep it dark, even if we wanted to. This fellow Pargent got it by post on Saturday morning. He told his sister, Miss Clara, that it must be a secret token from some admirer of his work. He was so pleased about it that he took it down to Penderworth to show his other sister. It was on his way back from there that he was killed. Oh yes, it’s interesting enough. We shall have to say that Tovey and Colburn got counters like this, and then there’ll be a fearful outcry against us for keeping it dark. ‘Had the police not displayed this criminal reticence, the victim would have understood the purport of the warning and adequate measures could have been taken to protect him.’ Oh yes, I know what’s coming all right.” + 

Inspector Whyland gazed savagely at the counter for a few seconds, then continued abruptly. + 

“Fortunately the envelope in which this one came had been kept. The counter was wrapped up in a piece of cheap writing paper, and put in a square envelope of the same quality. The address was typewritten. Our people at the Yard are trying to trace the machine it was done with. I wish them joy of the job. They can tell the make all right; but there must be thousands of them scattered through London.” + 

“If you don’t mind my suggesting it, it doesn’t follow that because Mr. Pargent received a counter he was murdered by the same hand that killed Mr. Tovey or Mr. Colburn,” said the herbalist quietly. + 

Inspector Whyland glanced at him quickly. “No, it doesn’t exactly follow,” he agreed. “But we’ll return to that later. I want to show you something else first. Look here.” + 

This time he produced from his pocket a paper packet, which he proceeded to unroll. From it he withdrew two sinister-looking blades, each stained a dull brown. + 

“These are the knives with which Tovey and Pargent were killed,” he said. “Don’t touch them, but tell me if you can tell one from the other.” + 

Mr. Ludgrove adjusted his spectacles, and bent over the knives. They were exactly similar, thin, with an extremely sharp point, about half an inch wide and eight inches long. Neither of them showed any sign of having ever possessed a handle. + 

“No, I can see no difference between them,” agreed Mr. Ludgrove. “I admit that they strengthen the supposition that Mr. Tovey and Mr. Pargent died by the same hand. But, admitting that this was the case, it only bears out my theory that the murders were the actions of a maniac. If they were not, if both men were killed with some definite motive, you have to discover some connection between them. Yet they moved in entirely distinct orbits, and, I should imagine, had nothing whatever in common.” + 

Inspector Whyland shook his head with a tolerant smile. “Theory’s all very well in its way, Mr. Ludgrove,” he said, as he replaced the knives in his pocket. “I can’t waste my time establishing connections. There’s evidence enough here to convince a jury that the same man killed all three of them. And I don’t fancy it’ll be very long before I lay hands upon him.” + 

“I sincerely hope your expectations will be realized, Inspector,” replied the herbalist, in a tone of faint irony which was lost upon Whyland. “I suppose it is indiscreet to ask whether you have any suspicions? I confess that for my part I am entirely at a loss. What about young Snyder, for instance?” + 

“Master Wal Snyder is out of this,” returned the Inspector shortly. “He was pinched a week ago for picking pockets in a tube lift, and is safely under lock and key. But I don’t mind telling you in confidence, Mr. Ludgrove, that I know the murderer lives somewhere in this district.” + 

Mr. Ludgrove lifted his eyebrows in real or assumed astonishment. “Indeed?” he exclaimed. “That is indeed a great step forward. Pray, how did you come to that conclusion?” + 

If the Inspector perceived the irony in his tone, he paid no heed to it. “Well, it’s pretty obvious,” he replied. “All three men were murdered in Praed Street, to begin with. Then, there’s another thing. The envelope in which the counter was sent to Pargent bore the postmark of this district, London, W.2. You can’t get away from it, everything points to the murderer living somewhere about here.” + 

Again Inspector Whyland paused. Then suddenly he rose and stood over the herbalist where he sat in his chair. “There’s another thing, Mr. Ludgrove,” he said, almost menacingly. “You said just now that it didn’t follow that because Pargent received a counter he was killed by the same man that murdered the other two. Do you see where that leads you? If the third counter was sent by a different hand, it can only have been sent by one of the very few who knew of the receipt of the first two. And all of them live in this district, you will remember.” + 

Mr. Ludgrove gazed up at him in mock alarm. “They do, indeed,” he replied. “It makes my blood run cold to think that I am one of them. Really, I am quite relieved to think that I have an alibi in the case of this last murder, at least.” + 

Inspector Whyland laughed shortly. “Oh, for that matter, I’m as much under suspicion as you,” he said. “But, you see, there are some people we know who couldn’t produce an alibi for the time when any of the murders were committed.” + 

And with that he turned abruptly on his heel and strode out of the room. + 

VII + 

The Black Sailor + 

That afternoon Inspector Whyland wrote in his report: “I had a long interview with Ludgrove. He is a shrewd fellow, and not easy to get anything out of. I am pretty sure that he has no definite knowledge on this matter, but he admits himself that some of his customers are not above petty crime, and it seems to me that he is the most likely man to hear any underground rumours that may be flying about. + 

“I managed to convey to him a pretty broad hint that I suspected one of his friends. I did this with a double motive. On the one hand, if he thinks that Copperdock or one of the others had anything to do with it, he will probably pass the hint on, and somebody may try to make a bolt for it, which would give them away. On the other hand, if he is convinced of their innocence, he will be all the more anxious to pass on to me any information he may get and which may tend to clear them. It is just a chance, but it may lead to something useful.” + 

The inspector’s strategy was indeed that of forlorn hope. Rack his brains as he would, interrogate as he might everyone who could possibly throw light upon the murder of Richard Pargent, he found himself up against a stone wall. Nobody could swear to having seen and recognized the victim from the time he entered the train at West Laverhurst until he had been seen to stagger and fall on the refuge in Praed Street. The ticket collector at Reading was almost positive about him, but, as he explained, he saw so many passengers in the course of his day’s work that he could not be sure of any particular one, unless there was something very remarkable about him or her. All he knew for sure was that if this was the gentleman, he was alone in the carriage when the train left Reading. + 

Nobody at Paddington had noticed him among the streams flowing from the arrival platforms, and it was impossible to establish whether or not he had left the station alone. The taxi-driver who had seen him fall had not seen the blow struck, could not even say whether anyone else had been standing on the refuge with him or not. It was a nasty, skiddy evening, and dark at that. He had enough to do to watch the traffic without worrying about people on refuges. It wasn’t until he had seen the poor man stagger into the road almost under his front wheels that he had even noticed him. And then his attention was fully occupied in pulling up and trying to avoid collisions. + 

Finally, neither of the Miss Pargents could throw the faintest glimmer of light upon the affair. Their brother was not the type of man to have secrets from his family. Both sisters appeared to know the inner history of every moment of his life since infancy, and insisted upon dispensing the knowledge at great length. As to his having an enemy in the world, the thing was absurd. He was a very retiring man, who lived only for his work, and had never sought adventure beyond the narrow bounds of the family circle. Inspector Whyland came away from his last interview with the sisters⁠—for Miss Margaret had been prevailed upon to come up to London⁠—convinced that it would have been impossible for the dead man to have embarked upon any clandestine enterprise without the knowledge of one or other of them. + 

He was equally unsuccessful in finding any link between Richard Pargent and any of the inhabitants of Praed Street. Their names were utterly unfamiliar to either of the sisters, and Mr. Pargent’s only connection with Praed Street appeared to be that he occasionally passed along it in a bus. Inspector Whyland was convinced that the same hand that had struck down Mr. Tovey, had killed Richard Pargent, and probably Mr. Colburn, though the receipt of the counter was the only link in the latter case. But what could be the motive for the murder of these three men, so entirely disconnected from one another? And, if one adopted the theory of a homicidal maniac, the difficulty was scarcely diminished. Homicidal maniacs either kill indiscriminately, or, as in the classic case of Jack the Ripper, they attack a certain class or type. Yet the receipt of the numbered counters implied some process of definite selection. Upon what possible grounds could such a selection be based? + 

The inquest helped the authorities not at all. Nothing beyond what Inspector Whyland already knew was elicited, and the only fresh sensation which it provided was the disclosure of the fact that each of the three victims had received a numbered counter. Whyland’s forecast of the results of this were proved to have been only slightly exaggerated. Most of the newspapers of the day following the inquest appeared with leading articles discussing the wisdom of official secrecy upon such a matter. A large number of practical jokers despatched counters bearing the number IV to their friends, many of whom arrived hotfoot at Scotland Yard demanding instant police protection. The fatal counter became for the moment a national symbol. The Opposition newspapers contained cartoons depicting the Prime Minister opening an envelope labelled “Public Opinion,” and containing a numbered counter. An enterprising Insurance Company issued a poster upon which appeared an enormous representation of the counter, and under it the words, “You need not fear this if you are insured with the Gigantic.” To find one in one’s Christmas pudding was an omen of bad luck for the ensuing year. Then, having played its part as a nine days’ wonder, the vogue of the numbered counter ceased as suddenly as it had begun. + 

Meanwhile, the police had been by no means idle. To Inspector Whyland it had always seemed that the focus of the whole business had lain in Mr. Copperdock’s shop. Mr. Copperdock had been an intimate friend of Mr. Tovey’s; Ted Copperdock was on familiar terms with Dick Colburn. It had been through Mr. Copperdock that he had first learned of the receipt of the numbered counters; the pipe which had been responsible for Mr. Colburn’s death been bought at Mr. Copperdock’s shop. Inspector Whyland began to regard the three victims as represented by the extremities of the letter Y, which, although they are not connected to one another, are each connected to a central point. But Mr. Copperdock was the central point, this graphic representation was incomplete until the connection between Richard Pargent and Mr. Copperdock could be established. And, try as he would, Inspector Whyland could find absolutely no link between the two. + 

Nevertheless, Whyland determined to make a very thorough investigation into Mr. Copperdock’s habits and associates. He was rewarded by the discovery of two very interesting facts. A representative of Scotland Yard, announcing himself as an agent of the Planet Typewriter Company, the manufacturers of the machine owned by Mr. Copperdock, and used by his son for writing business letters, called at the tobacconist’s shop, ostensibly for the purpose of inspecting the machine. He succeeded in carrying away with him a specimen of its work, which was submitted to experts. They reported that, although there were no perceptible peculiarities in any of the letters which would enable them to identify this specimen with the address on the envelope sent to Richard Pargent, there was, on the other hand no discrepancy between the two types, and that therefore the envelope might well have been typed on Mr. Copperdock’s machine. + 

This, though disappointingly inconclusive, was to Whyland’s ideas a point to be remembered should any corroborative evidence come to light. Among the circle in whose actions he found himself interested, the Copperdocks were the only people who possessed a typewriter at all. As a matter of fact, Mr. Copperdock had only purchased it quite recently, at the instance of Ted, who while stoutly maintaining that no respectable tradesman could be without one, had been suspected by his shrewd father of less disinterested motives. Certainly it had seemed only natural that, the machine once purchased, the expert Ivy should come in of an evening and show Ted how to work it; but Mr. Copperdock had a way of winking at his son behind her back which made that ingenuous youth blush most embarrassingly. + 

The second curious fact was discovered by Inspector Whyland almost by accident. In his study of Mr. Copperdock and his associates, he had taken to frequenting the saloon bar of the Cambridge Arms, carefully choosing such times as Mr. Copperdock was busy in the shop. There was nothing in any way suspicious about the Cambridge Arms; it lay in one of the streets which run southwards from Praed Street, and was consequently almost hidden in a backwater. Its remarkably cosy little saloon bar was patronized chiefly by the neighbouring small tradesmen, and its habitués were all well-known to the proprietor, with whom Whyland soon became on confidential terms. + 

A couple of days after the inquest on Richard Pargent, Whyland turned into the Cambridge Arms just as its doors were opened, at five o’clock. The proprietor met him with a smile, and, having executed his order, leant over the bar and entered into conversation. + 

“I never thought, when I opened up last Saturday, that that poor fellow was being murdered at that very minute,” he began. “Just about five o’clock, wasn’t it, sir?” + 

Whyland nodded. “The clock was striking five as they picked him up,” he replied. + 

“I remember the evening well,” continued the proprietor. “Though it wasn’t until nigh upon seven that I heard anything about it. I says to my wife it was that wet and foggy that even our regulars wouldn’t be in till later. But there you are, you never can tell. I hadn’t opened this bar, not more than five minutes, when in comes one of my best customers, Sam Copperdock, the tobacconist. You may have met him here, sir?” + 

Whyland nodded non-committally, and the landlord proceeded. + 

“I was a bit surprised to see him, sir, because Sam doesn’t usually come along until eight, unless it happens to be Thursday, when he closes early. ‘Hullo, Sam, you’re on time tonight,’ I says, jocular like. ‘Oh, I’ve only come in for a drink,’ he says; ‘The bottle’s empty at home, and I couldn’t scrounge one from old Ludgrove opposite, he’s away.’ He has a double, and goes back to his shop. The bar was pretty nigh empty till about seven, when a fellow comes in and tells me about the murder.” + 

Inspector Whyland deftly turned the conversation. He knew that if he questioned the man his suspicions would be aroused, and this he was anxious to avoid. Without any appearance of haste he finished his drink and left the premises. Once round the corner, he walked swiftly to the spot where Richard Pargent had been murdered, counting his paces as he went. + 

Could Mr. Copperdock have committed the murder? It was quite possible. If he had left his shop a few minutes before five, he would have had plenty of time to reach the exit from Paddington station, plunge the knife into his victim, and be at the Cambridge Arms at five minutes past. But, if he were the criminal, a thousand puzzling questions presented themselves. How did he know that his victim would be arriving at Paddington at 4:55 that evening? Above all, why should Mr. Copperdock, the tobacconist, have any grudge against Mr. Pargent, the minor poet? And then again, Whyland was convinced that the murderer of Richard Pargent had been the murderer of James Tovey. But, at the moment when Tovey had been killed, Mr. Copperdock was in his sitting-room with his son and the murdered man’s daughter. The riddle appeared to be insoluble. + 

Whyland turned abruptly, boarded a bus, and took a ticket to Oxford Circus. Here he dismounted, and turned into the first picture-house which presented itself. He had discovered long ago that this was the surest way of securing freedom from interruption. Here for a couple of hours he sat motionless, neither seeing the pictures nor attentive to the strenuous efforts of the orchestra. And as he sat, a new theory slowly unfolded itself in his brain. + 

Samuel Copperdock, whom he had studied so carefully, did not appear to him to be a deliberate criminal. He was not of the type which harbours revenge, and he did not seem either clever or painstaking enough to work out the details of a premeditated murder. Although, if it were true that he had formed a design to marry Mrs. Tovey, the murder of Mr. Tovey might be said to be advantageous to him, it was inconceivable that he had had any hand in it. He could not have struck the blow himself, and, since he was not a rich man, it was difficult to see what inducement he could offer to a hired assassin. In all human probability, Mr. Copperdock was innocent of the murder of James Tovey. + 

But, on the other hand, this murder, followed so closely by the mysterious death of his other acquaintance, Colburn, had made a great impression upon him. He had thought and talked of little else, and, as it happened, he had known every detail. He had seen the knife with which James Tovey had been killed; he, in common with very few others, had known of the receipt of the marked counters. Suppose that the crimes had had such a powerful effect upon his imagination that he had felt an irresistible impulse to imitate them? Such things were known, were in fact a commonplace of the criminal psychologists. + 

Upon this assumption, the rest was easy. Mr. Copperdock had learnt by some accident that this man Richard Pargent would arrive at Paddington at 4:55 on Saturday, and had selected him as a likely victim. His imitative faculty fully developed, he had sent him the numbered counter, and had purchased a knife similar to the one which he had already seen. Then, just before the train was due, he had left his shop, met his victim, committed the crime, had a drink to steady his nerves, and then come home. + 

The theory was plausible, but Inspector Whyland knew well enough that so far he had not a fragment of real evidence with which to support it. But, unless he were to adopt the suggestion of Mr. Ludgrove, that some homicidal maniac was responsible, Whyland could see no alternative. The lack of motive was so extraordinarily puzzling. The murders had been utterly purposeless, and the only possible theory could be one which took full account of this fact. And then again, how account for the despatch of the numbered counters? If the murders had been inspired by irresponsible impulse, what had been their object? + 

Still deep in thought, Inspector Whyland left the picture-house and walked slowly back to the police station through the less frequented streets. It was a little past eight on a typical December evening, with a light wet mist which magnified the outlines of the passersby and covered the pavements with a shining dampness. But the weather never had much effect upon Whyland, and, beyond a passing reflection that on such an evening murder in the streets of London was not, after all, an enterprise presenting any great difficulties to a determined man, he paid no great attention to it. + 

He reached the police station without adventure, ordered a modest supper, and sat down to deal with the mass of reports which awaited him. He was thus engaged when a sergeant entered the room, with the message that a man giving the name of Copperdock wished to speak to him on the telephone. He rose, walked to the instrument, and picked up the receiver. “Inspector Whyland speaking,” he said coldly. + 

“Is that you, Inspector?” came an excited voice, which Whyland recognized at once. “Can you come and see me at once? I’ve something very important to tell you.” + 

Whyland hesitated for a moment. Whatever it was that Mr. Copperdock had to say to him, a visit to his house could afford him an excellent opportunity for keeping his eyes open for some clue in support of his theory. “Yes, I’ll come along straight away,” he replied. With a word to the sergeant, he left the station and walked rapidly to Praed Street. + 

It was about a quarter to ten when he arrived and rang the bell outside Mr. Copperdock’s shop. The tobacconist was obviously awaiting him, and the door was opened immediately. With a brief word of greeting, Mr. Copperdock led the way upstairs to the sitting-room. Then, shutting the door carefully behind him, he turned dramatically, “I’ve seen that there black sailor!” he exclaimed in a hoarse whisper. + 

Inspector Whyland looked at him sharply. When the reward had originally been offered, he had been overwhelmed by a flood of people who had claimed to have seen the “black sailor,” but of late this elusive figure had ceased to occupy the popular imagination. Was this a vindication of his theory, showing that Mr. Copperdock’s brain was completely under the influence of the crime? + 

“You have seen the black sailor? Sit down and tell me all about it, Mr. Copperdock,” he replied gravely. + 

But Mr. Copperdock was far too excited to sit down. “I see him plain as I see you now,” he exclaimed. “Just after I left the Cambridge Arms⁠—” + 

But Inspector Whyland put out his hand and forced him gently into the nearest chair. “Now, look here, Mr. Copperdock, if your information is to be of any use to me, you must tell it to me in the proper order. Begin by telling me how you spent the evening.” + 

“Soon as I shut up shop at eight o’clock, I goes off to the Cambridge, same as I always does,” replied the tobacconist protestingly. “Ted went out too, he’s taking Ivy to the pictures, and they won’t be back for an hour or so yet. I has a couple there, sitting in front of the fire, and it wasn’t until nigh on closing time that I left. There wasn’t anybody there as was coming home my way, so I starts off home alone. And I hadn’t gone more than a hundred yards when I runs slap into the black sailor!” + 

“What do you mean when you say you ran into him?” interrupted Whyland. + 

“Just what I says. I saw someone come round the corner, and before I could move we ran into one another. He was a great big fellow, and I could see him perfectly plain, we was right under the lamp. He bent down and looked straight at me, and you could have knocked me down with a feather. It was the black sailor, all right. He was muffled up in a great heavy coat, but I could see his beard, and his woollen cap, and a great red scar down the right side of his face. He glared at me as though he were going to hit me, and I hollered out, being sure he was going to do me in. Then all at once he turns his back and walks off at a tremendous pace. After a bit I follows him, hoping to meet a copper. But he suddenly turns in to the Edgware Road, and by the time I gets there I’d lost him.” + 

“H’m,” said Inspector Whyland. “That must have been nearly an hour ago now.” He paused for a moment, then, realizing that in Mr. Copperdock’s present excited state it would be impossible to get anything coherent out of him, he rose and took his leave. + 

“Well, good night, Mr. Copperdock,” he said abruptly. “It’s a pity you didn’t catch your man. I’d better get back to the station and warn my people to look out for him.” + 

As he left the shop, he noticed that Mr. Ludgrove’s door stood open, and as he crossed the road, the herbalist himself appeared in the entrance. “Good evening, Inspector,” he said politely. + 

Obeying a sudden impulse, Whyland stopped and returned the greeting. “Good evening, Mr. Ludgrove,” he replied. “May I come in for a moment?” + 

“By all means, come along,” replied the herbalist, leading the way into his sanctum. “I do not drink much myself, but perhaps you will take some refreshment yourself?” + 

He busied himself with a bottle and a glass, while the Inspector drew up a chair to the blazing fire. Then, when his host had seated himself, Whyland glanced at him with a slight smile playing about his lips. + 

“Our friend Mr. Copperdock has seen the black sailor,” he remarked. + 

“Seen the black sailor!” exclaimed the herbalist incredulously. “When and where⁠—if I may ask?” + 

“Listen, and I’ll tell you all about it,” replied Whyland. “About an hour ago outside the Cambridge Arms.” + 

Mr. Ludgrove laughed softly at something in the tone of the Inspector’s voice, then suddenly became serious. + 

“I do not think that I should place too great importance upon this incident,” he said. “Mr. Copperdock is a most excellent person, and I have the greatest respect for him. But I have often suspected that his visits to the Cambridge Arms have⁠—shall I say, a pernicious effect upon the accuracy of his observations.” + 

“He seemed a bit excited, certainly,” replied Whyland. “But he was quite positive that he had seen the man.” + 

Mr. Ludgrove shook his head. “Now, this is strictly between ourselves, Inspector,” he said. “I make an invariable practice of taking a walk every evening, as soon as my clients give me the opportunity. This evening I went out soon after eight, and walked in the direction of Hyde Park. As it happened, I was returning past the Cambridge Arms, when I saw a figure which was unmistakably that of Mr. Copperdock leave the entrance of that house. I hastened my steps to overtake him, when suddenly he stopped, shouted, and after a moment or two, set off in the direction of Edgware Road. I could not imagine what was the matter, since but for us two the road was deserted as far as one could see for the mist. I was within twenty or thirty yards of him, and I certainly saw no black sailor.” + 

It was Inspector Whyland’s turn to smile significantly. “It does not altogether surprise me to learn that Mr. Copperdock suffers from hallucinations,” he said. + 

At No. 407, Praed Street + 

Although the unexplained murders which had taken place in Praed Street were soon forgotten by the general public, their shadow hung heavily over the neighbourhood in which they had been committed. The fact that the three deaths had taken place within comparatively few hundred yards of one another could not fail to have its effect upon the local imagination. A very noticeable change came over the usual cheerful and careless life of Praed Street. The evening pavements were no longer blocked by a strolling, noisy crowd. Women and children were rarely to be seen abroad after dark. Even men, traversing the street upon their lawful occasions, had a way of keeping close to the inner side of the pavements, and crossing the road upon the approach of any unfamiliar form. + 

Christmas passed in this atmosphere of intangible fear; the old year died and the new year came in with a welcome spell of clear and frosty weather. But, in spite of the fact that no further tragedies occurred, the shadow still lay heavily upon the district. Ludgrove, listening to the whispered and entangled stories of his clients, became more and more certain that, even in the hidden depths of the underworld, there was no knowledge of the agency by which the crimes had been committed. + 

Had such knowledge existed, it must inevitably have been divulged to him. The police, under the direction of Inspector Whyland, were engaged in passing a fine-toothed comb through the Paddington district, and the minor offenders disturbed in this process were as concerned as a colony of ants unearthed by a spade. Mr. Ludgrove was visited furtively late at night by anxious people seeking advice how to conceal the evidence of their misdemeanours from the prying eyes of the police. He questioned each of these closely, but the more he did so the more he became convinced that none of them had the slightest inkling of the perpetrator of the murders. + 

Another section of his clients, however, equally furtive and mysterious, had clues in plenty, which they seemed to think entitled them to some reward. These, after assuring themselves that no one could overhear them, would produce an incoherent story of how one of their neighbours must be the criminal. He had been heard to utter threats that he would do someone in some day, he had been in Praed Street on the night when Mr. Tovey was murdered, in the neighbourhood of Paddington station when Mr. Pargent was killed. Others, again, had met a muffled figure brandishing a knife, or had seen a dark man with a beard standing in the shadow thrown by a projecting wall. Two or three searching questions were always sufficient to prove that their suspicions were baseless. + 

The murders in Praed Street were thus peculiar in the annals of crime. In nearly every case of a crime being committed, there are others besides the criminal who know all the facts. The police know this, but their great difficulty is to secure evidence sufficiently convincing to lead to a conviction. There is a certain esprit de corps in the constant strife between the professional criminal and the police, and those who know are careful to keep their knowledge to themselves. But in this case, had there been any of the inhabitants of the district in the secret, Mr. Ludgrove would have obtained some hint of it. It seemed conclusive that the criminal was either working alone and independently, or came from some other district. + 

This was the state of affairs towards the end of January. The police were completely baffled; Inspector Whyland, although he still favoured the theory he had evolved in the picture-house, had failed to find any evidence upon which he could act. He hardly knew whether to attribute Mr. Copperdock’s story of his meeting with the black sailor to pure hallucination, or to an attempt to divert suspicion from himself. In either case, it could be made to fit in with the theory that he had murdered Richard Pargent under the influence of what the psychologists called an imitative complex. Whyland redoubled his activities, and a most accurate watch was kept upon Mr. Copperdock’s movements. A month had elapsed since the murder of Richard Pargent when Mr. Jacob Martin, the prosperous wine merchant of the Barbican, opening his morning post in his comfortable office, came upon a typewritten envelope, marked “Private and Confidential.” He ripped it open with the paper cutter which lay upon his desk, and unfolded the letter it contained. It also was typewritten, on plain paper. Only the signature “John Lacey” was in ink. + 

Mr. Martin, a portly, grey-haired man of between fifty and sixty, read the letter through twice, with a gathering frown upon his face. He had prospered exceedingly since the day when he had first set up in business for himself as a wine merchant, so much so that his competitors wondered at his success. There had, from time to time been rumours, quickly suppressed, to the effect that Mr. Martin had other means of livelihood than his ostensible business. But Mr. Martin was a remarkably astute man, and had hitherto managed to avoid undue inquisitiveness. + 

And now, like a bolt from the blue, came this extraordinary letter. Confound John Lacey, and his prying habits, whoever he might be. That little cellar under the back office! How well he remembered it. It had been the scene of many most profitable transactions, had harboured treasures for which the police of two continents had searched in vain. For Mr. Martin was a receiver of stolen goods, not a mere general practitioner of the art, but a specialist whose services were utilized only by the aristocracy of thieves, and whose particular function was turning into cash only the most valuable jewellery. + 

With an exclamation of annoyance Mr. Martin turned once more to the letter. “Dear Sir, I venture to address you upon a subject which will no doubt interest you,” it ran. “I have recently acquired a lease of the premises No. 407, Praed Street, which I understand, were in your occupation up till some fifteen years ago. Since you vacated them, these premises have been occupied by a clothier, who did not require the extensive cellarage, which was boarded up. In the course of certain alterations which I am having made to the premises, the entrance to the cellars has once again been opened. In the course of my investigations I have made a most interesting discovery in the small cellar beneath the back office. + 

“I should perhaps report this discovery to the authorities, but I have thought it best to consult you upon the matter before doing so. This letter should reach you by the first post tomorrow (Saturday) morning. I should be glad if you could make it convenient to meet me on the premises at 2 p.m. that day, when the workmen who are at present employed there will have gone. I can then show you my discovery, and we can consult upon the most suitable steps to be taken in the matter. Should you not find this convenient, I shall assume that the subject does not interest you, and shall report the matter forthwith to the police. Yours faithfully, John Lacey.” + 

A blackmailing letter, without a doubt, Mr. Martin could see at a glance. But what on earth could the fellow have discovered? Fifteen years ago, when Mr. Martin moved from Praed Street to the Barbican, he had taken the utmost care to destroy every trace of the purpose to which that little cellar had been put. He racked his brains to try and think of anything that could possibly have been overlooked, but without success. Even those ingeniously contrived recesses in the walls had been torn out, leaving nothing but the bare brick. Mr. Martin had done the work with his own hands, not caring to trust anyone else with so delicate a matter. Yet, after all, in spite of all his care, he must have left some clue, which this infernal fellow Lacey had somehow blundered upon. + 

He brushed aside as absurd the suggestion that “Lacey” could conceal the identity of one of those with whom he had done business, who knew the secret of the cellar and had adopted this clumsy plan to blackmail him. The circle of his secret clients was a very narrow one; he knew them all and was well aware that blackmail was neither in their line nor in their interest. The expert in acquiring jewellery concentrated upon his particular art; he did not descend to blackmail, especially of the one man through whose agency he was able to dispose of his spoil. No, there was no doubt about it, a slip had been made, a slip which had lain undiscovered all these years, through the circumstance that his successor, the clothier, had found no use for the cellars and had boarded up the entrance to them. + 

There was nothing for it but to carry out the suggestion contained in the letter, and meet the man in Praed Street at two o’clock. He must find out the nature of this mysterious discovery, and take steps to ensure that all evidence of it be securely destroyed. Lacey, of course, would demand some compensation for holding his tongue. The sum he demanded would depend upon the importance of what he had found. Well, they would discuss terms, alone in that empty house, in the very cellar which Mr. Martin remembered so well. + 

Mr. Martin stroked his chin reflectively. What sort of fellow was this Lacey, he wondered? He himself was a powerful man, proud of his own powers of intimidation. It ought to be simple enough for him to destroy the evidence first then to tell Lacey to go to the devil and do his worst. He unlocked a drawer of his desk and drew from it a small automatic pistol, which he slipped into his pocket. It was with a smile that he remembered that Praed Street had recently acquired a sinister reputation. Well, if any accident should happen⁠— + 

Mr. Martin’s office closed at one o’clock on Saturdays. He left a few minutes before that hour, having put John Lacey’s letter in his pocket and examined the mechanism of his automatic. Then he consumed a hasty lunch at a chophouse nearby, and walked down the street to Aldersgate Metropolitan station, where he took a ticket to Paddington. He emerged into Praed Street at about five minutes to two, and began to walk along that thoroughfare in the direction of Number 407. + 

Praed Street, at this time on a fine afternoon, wore its usual air of busy activity. The exodus from central London was still at its height, the crowds still passed along in bus or taxi towards the portals of Paddington station. On the other hand, the inhabitants of the neighbourhood, released from work, were beginning their weekend shopping. The pavement was crowded, and Mr. Martin, who had some distance to walk to his destination, looked about him curiously. Since he had put up his shutters for the last time, fifteen years ago, he had rarely revisited Praed Street, and even then he had only traversed it in a taxi, going to or from Paddington. The street had changed a little since he had been an inhabitant of it. Certainly there were fresh names over many of the shops, and, here and there, there had been alterations to the buildings he remembered. He glanced at a board on the opposite side of the street. Elmer Ludgrove. That was new since his day. The rather musty-looking shop was conspicuous among its neighbours by being closed. Praed Street, as a rule, does most of its business on Saturday afternoon. + 

Mr. Martin walked on a step or two, then hesitated for an instant. So Sam Copperdock, from whom he bought his cigarettes in those early days, was still here. Mr. Martin had long ago abandoned cigarettes for cigars, but he felt a momentary impulse to go in and renew the old acquaintance. Sam Copperdock had been a good customer of his, he remembered. Many a bottle of whiskey had he sold him. But on second thoughts he refrained. Perhaps it would be just as well, in the light of what might happen during the next half hour or so, that his visit to Praed Street remained unsuspected. + 

Mr. Martin walked on, and in a few minutes found himself outside Number 407. It was much as he remembered it, but that it was lying empty, and showed signs of being refitted for a new tenant. The windows were almost obscured with patches of whitewash, but peering through them he could see trestles, timber, shavings, all the litter which betrays the presence of the carpenter. So far, then, the letter was correct. Mr. Martin, after a furtive glance round about him, walked up to the door and tried it. It was locked. + 

He drew out his watch and consulted it. It was nearly five minutes past two, but he remembered that he had noticed that morning that it was a trifle fast. Lacey, whoever he was, would doubtless be along in a moment. Mr. Martin hoped he would be quick; he had no wish to be recognized outside the premises by any of his old acquaintances. A sudden thought struck him. Perhaps Lacey was already inside, waiting for him. There was an electric bellpush by the side of the door. Mr. Martin pressed it firmly, but could hear no answering ring above the roar of the traffic. Then all at once he became aware that a small girl was standing by his side, looking up at him with an appraising expression. + 

As he turned to look at her, she made up her mind and spoke. “Is your name Mr. Martin?” she asked. + 

Mr. Martin frowned down at her. “What’s that got to do with you?” he replied. + 

“ ’Cos if you are, Dad told me to give you the key,” she continued, quite unabashed. “And there’s a message from Mr. Lacey that you’re to go in and wait for him, as he’ll be a few minutes late.” + 

“Oh, I see,” said Mr. Martin with a smile. “Yes, my dear, I am Mr. Martin. How did your father come to have the key?” + 

She jerked her head towards a sweet shop two or three doors away. “We lives there,” she replied curtly. “Mr. Briggs the builder, what’s working here, leaves it with us because he’s my uncle. His men come and get it in the morning. And Mr. Lacey, him what’s coming here, telephoned just now to say you was coming to see the drains and I was to give you the key.” + 

“Oh yes, that’s right,” said Mr. Martin, completely reassured. “Thank you, my dear, I’ll see that either Mr. Lacey or myself brings you back the key so that your uncle’s men may get in on Monday morning. That’s the shop, there, isn’t it?” + 

He waited until the child had disappeared into the shop, then opened the door of Number 407 with the key which she had given him, walked in and closed the door behind him. Here he paused for a moment, thinking rapidly. He felt that he was up against a brain as agile as his own, and that the coming interview would demand all his skill if he were to bring it to a favourable issue. This man Lacey had taken steps to advertise the fact that Mr. Martin had entered the premises, obviously as a precaution against foul play. His automatic would be of no use to him, he would have to rely upon his brains instead. + 

Then suddenly it flashed upon him that he had been given a very fortunate opportunity. It was not to be supposed that Lacey had left his discovery, whatever it was, lying about the cellar in full view of the workmen who had been there that morning. But, if he could have a quiet look round by himself, he might gain some clue to the nature of the discovery, and so be prepared to meet Lacey when he arrived. + 

Mr. Martin was not anxious for Lacey to come upon him unawares while he was searching the cellar. Fortunately, the possibility of such an event could easily be guarded against. He bolted the door top and bottom, and noticed with satisfaction that the bolts were brand new, evidently part of the alterations which the new tenant was making to the premises. Then, after glancing round the ground floor, and making sure that nobody was hidden there, he made his way to the top of the stairway which led down to the cellars. The upper part of the house had no connection with the shop, and was approached by a separate entrance. + 

He saw at once that the letter had been correct as to the alterations being made. During his tenancy the cellars had been lighted by gas, but now electric light was being installed throughout. Mr. Martin could see the run of the wires and the fittings for the lamps, but he noticed that the lamps themselves had not yet been inserted. This fact did not worry him. He had a box full of matches in his pocket, and one of these he lit as he cautiously descended the stairs. The builders’ litter was here, as everywhere, and he picked his way among it until he stood in the main vault below the shop. It smelt close and musty, as though it had only recently been opened up after a long period of disuse. Mr. Martin, holding a lighted match above his head, glanced rapidly round. Nothing had been altered here since he remembered it, except that a new brass switch stood behind the door, and two empty lamp sockets projected downwards from the ceiling. + 

The way to the little cellar below the back office lay along a narrow passage, and this Mr. Martin followed, striking a fresh match as he went. Every detail came back to him, as though he had last passed this way yesterday, instead of fifteen years ago. The door of the little cellar closed with a spring; as he pushed it open the spring creaked with a note which he remembered so well, and the door closed behind him with the same muffled bang. Again he raised his match and looked around him anxiously. The cellar appeared to be the same as he had left it, even to a mildewed packing case against the wall, which had sometimes been used as a table. Only here, as in the larger cellar, the electricians had been at work. There was a lamp holder on the ceiling, but this time it held a lamp. It was evidently by the light of this lamp that Lacey had made his discovery. There was no reason why he should not use it too. + 

The match had burnt down very near his fingers, but as he dropped it he caught sight of the switch. Without troubling to light another match he groped his way towards it and turned it on. There was a flash and a sharp report, but the cellar remained in complete darkness. Mr. Martin, with a gasp, leapt for the door in sudden panic. Someone hidden in the cellar must have fired at him. Then, after a moment, the absurdity of the idea forced itself upon him. The report had not been nearly loud enough for a pistol, and the cellar was far too small to conceal anybody. With a short laugh, but with trembling fingers, he felt for his matchbox and struck a light. + 

Then at once he saw what had happened. The globe had burst as he turned on the current, and only the butt remained in the holder. He turned to look at the switch, and then for the first time he noticed that something white was hanging from it by a string. He bent down and held his match close to it. It was a white counter, bearing the figure IV in red ink. + 

With a sudden access of fear he clutched at it, in order to examine it more closely. The string broke, and he stared at the counter in his hand, fascinated. He began to realize his position. He had been lured to this empty house, and the assassin was no doubt even now in the passage outside, waiting to plunge his deadly knife into him as he emerged. Thank heaven, he had brought his automatic with him! + 

Mr. Martin was no coward. His plan of defence was quickly made. Throwing the match away, he took his stand on the far side of the cellar, facing the door, his automatic in his hand. If his assailant came in, he would hear the creak of the spring, and could fire before the man could reach him. + 

For a second or two he waited, tense and with ears strained for the slightest sound. It was very quiet in the cellar; the rumble of the traffic in Praed Street came to him but faintly. Then, all at once, he caught his breath as a pungent and unfamiliar smell reached him. Suddenly he found himself choking, dizzy, his senses leaving him. An overpowering impulse to escape from the cellar swept through him, drowning his fear of what might be awaiting him outside. He staggered towards the door, his hands clawing wildly over its damp surface. There used to be a string by which one pulled it open, but Mr. Martin could not find it. Vainly he strove against the awful numbness which closed in upon him. He must find the string, must⁠— + 

With a crash Mr. Martin fell down at the foot of the door. The little cellar resumed its accustomed silence. + 

A Strange Affair + 

It was not until shortly after eight o’clock on Monday morning that Inspector Whyland, who had arrived early at the police station, received the startling intelligence that there was a dead man lying in the cellar of Number 407, Praed Street. He immediately jumped into a taxi, and was met in the doorway of the empty house by a man who introduced himself as Mr. Houlder, the builder who was carrying out certain alterations for the new tenant, Mr. Lacey. + 

“My men found him when they came in this morning,” he said. “They telephoned to me and I told them to fetch a policeman. He rang you up, I understand. I think I can explain how the man got in, and who he is.” + 

“Thanks very much, Mr. Houlder,” replied Whyland. “I think we’ll have a look at him first, if you don’t mind. Will you lead the way?” + 

They descended to the cellar together, Mr. Houlder leading the way with an electric torch. As they arrived at the passage leading to the small cellar, a constable appeared and saluted. + 

“Ah, you’re in charge here, I suppose?” said the Inspector. “You haven’t touched anything, I hope?” + 

“Not since I’ve been here, sir, but I understand that the body was moved accidentally before I came, I’ve got the man who found him here, sir.” + 

A man, who had been hidden in the gloom behind the policeman, came forward at this. He explained that he was the electrician who had been wiring the cellars. He had very nearly finished the job on the previous Saturday, and had left about noon. The carpenters were still working on the ground floor when he left. He returned just before eight this very morning, found the carpenters already at work, and went down to the cellars to put the finishing touches to the job. The door of the small cellar appeared to be jammed, and he pushed against it to open it. When he had got it open far enough to squeeze through, he found the body of a man lying against it. He had immediately run upstairs and told the foreman, and had waited there till the constable came and asked him to show him the body. + 

Inspector Whyland dismissed Mr. Houlder and the electricians, and went on into the cellar with the constable. “There’s something queer about this business, sir?” said the latter, as soon as they were alone. “I had a look round while I was waiting for you, and the first thing I saw was one of them white counters, same as the others had. There it lies, sir, I didn’t touch it.” + 

They were in the cellar by now, and Whyland glanced at the counter, lying in the beam of light which the constable had thrown upon it. “With the figure IV on it, I’ll wager,” he muttered. “Yes, I thought so. We’ll try for finger marks, but I’ll bet it’s no good. Now, let’s have a look at this dead man.” + 

The constable turned his lamp on the prostrate form, and Whyland knelt down and gazed at it intently. The body was lying doubled up as it had fallen, and was quite cold. + 

“H’m,” said Whyland, rising to his feet. “We can’t do much more till the doctor comes. You don’t know who he is, I suppose?” + 

“Mr. Houlder said he believed his name was Martin, sir,” replied the constable cautiously. + 

“Well, you stay here till the doctor comes. I’ll go and have a chat with Houlder. Just throw your light over the floor for a minute. Hullo, what’s this?” + 

He strode across the cellar and carefully picked up a small automatic. “Hasn’t been fired,” he muttered. “Now I wonder who that belongs to? Just see if you can spot anything else. Don’t touch it, if you do.” + 

He went upstairs again, and drew Mr. Houlder aside into a quiet corner. Mr. Houlder’s story was a very simple one. His foreman had orders to leave the key to the house with Mr. Briggs, the confectioner, three doors off. Mr. Briggs was Houlder’s brother-in-law. The reason for this arrangement was that whoever came on the scene first could get the key and start work. On Saturday the key had been left as usual, about 12:30. + 

On Saturday evening, about nine o’clock, Mr. Briggs had come to his place and told him that Mr. Lacey, who knew about the key arrangement, had rung him up to say that a Mr. Martin was coming to inspect the drains. Mr. Lacey was to have met him at two o’clock, but would be delayed. Would Mr. Briggs keep a lookout for him and give him the keys. Mr. Briggs had promised to do so, and his daughter Marjorie had seen Mr. Martin, who had promised to bring back the keys, but had not done so. Mr. Briggs had forgotten all about them until the evening, and then, finding that the door of Number 407 was securely locked, had supposed that Mr. Martin had gone away with the keys in his pocket. Mr. Houlder had agreed with this theory, and had given Mr. Briggs a duplicate key which he happened to have. + 

The foreman had called on Mr. Briggs, and had been given the duplicate key. But when he came to try the door, it would not open. He made several attempts but, finding them unavailing, desisted and made his way through a window at the back. He then discovered that the door was bolted on the inside, a circumstance which puzzled him tremendously. Shortly afterwards the electrician arrived, and his thoughts were diverted into other channels. + 

Inspector Whyland spent a few minutes talking to the foreman, who confirmed the latter part of Houlder’s story, and had barely finished his enquiries when the doctor arrived. The two went down to the cellar together, and the doctor, without wasting words, proceeded to examine the body, Whyland watching him intently. + 

“Poisoned!” pronounced the doctor, after a short interval. “Prussic acid, by all signs of it, but I can’t be sure till I’ve made a postmortem. You’ll have him taken to the mortuary, of course? Queer place to choose for suicide. How did he get in here?” + 

Inspector Whyland shook his head. “I don’t think it’s a case of suicide, doctor. Look here!” + 

He pointed to the numbered counter. The doctor glanced at it and sniffed contemptuously. “You fellows have got counters on the brain since that business last month,” he said. “How do you know he didn’t put it there himself to throw you off the scent? It’s not uncommon for suicides to try and make their deaths look like murder. You’ll find there’s some question of insurance behind it. Well, I’ll be along at the mortuary and let you know the result of the P.M.” + 

The doctor bustled away, and Whyland, having made arrangements for the removal of the body, made a very careful examination of the cellar. This done, he sent the constable for the electrician, and asked him to look round and see if he could find anything which had not been there when he left on Saturday. + 

The man looked about him carefully, and suddenly pointed to the ceiling with an exclamation of astonishment. “Why, there’s the butt of a broken lamp in that holder, sir,” he said. “I didn’t put no lamps in before I left. That’s one of the things I came here to do today.” + 

“Well, take it out and put in a fresh lamp,” replied Whyland. “I didn’t know the current was on. We’ll be able to see what we’re doing.” + 

The electrician obeyed him, and no sooner had he put the new lamp in the holder than the cellar was flooded with light. “Hullo!” he exclaimed. “The switch is on. I’ll swear I left it off on Saturday. Why, that’s queer! This isn’t the butt of an ordinary lamp at all. Looks to me like one of them electric detonator things, made to go into a lamp-socket. And it’s gone off, too. You can see where it’s blackened, sir.” + 

“Was the current on on Saturday?” asked Whyland, quickly. + 

“Yes, sir, I connected up in the morning,” replied the electrician. “Somebody must have put that thing in the lamp-holder, then turned the switch on. Well, that’s a rum go, and no mistake.” + 

Whyland, having cautioned the man to say nothing until the inquest, left the house and walked into the confectioner’s shop. Here he interviewed Mr. Briggs and his daughter Marjorie, and obtained from them the story of Mr. Martin’s arrival at Number 407, and of the telephone message from Mr. Lacey. By this time the body had been conveyed to the mortuary, and Whyland set to work to examine the contents of the dead man’s pockets. His most interesting discoveries were the letter which he had received on Saturday morning and the missing key of Number 407. + 

The doctor arrived and performed his postmortem, which confirmed the suspicions he had already formed. “Prussic acid, right enough, and a pretty powerful dose by the look of it. The queer thing about it is that he seems to have died from breathing the vapour rather than from swallowing the stuff. Looks as if he’d uncorked a bottle of the strong acid and sniffed at it. You didn’t see anything of the kind lying about the cellar, I suppose?” + 

Whyland shook his head. “No, I didn’t,” he replied. “The only thing I found lying about was a loaded automatic which hadn’t been fired.” + 

“What did I tell you?” said the doctor triumphantly. “Suicide, without a doubt. He took a pistol with him in case the stuff didn’t act. You’re suggesting that anybody murdered a powerful man like that by making him inhale prussic acid against his will, are you? Why, the idea’s absurd.” + 

Inspector Whyland left the mortuary in a very thoughtful frame of mind, and returned to the police station. Here he set the telephone to work and invoked the aid of his colleagues. By the middle of the afternoon he had collected some interesting information respecting both Martin and Lacey, upon which he began to build up his own theory as to the former’s death. + 

Mr. Martin had carried on a wine merchant’s business at 407, Praed Street, until fifteen years before. He had then moved to the Barbican, where he employed two clerks and a couple of packers. He had never married, and lived at a boarding house in Streatham. He had more than once gone away for the weekend without notice, and his absence had therefore caused no concern. He was not known to have any enemies, although more than once there had been some unsavoury rumours in circulation as to his dealings with girls whom he had engaged as his secretaries. His movements on Saturday morning were traced from the time he left his office to his reaching Aldersgate station. Finally, as a result of the hint contained in the letter signed John Lacey, the police had searched his office, and had found there certain papers which threw a flood of light upon a long sequence of jewel robberies extending back for the last twenty years. + 

Mr. Lacey was the owner of a group of grocer’s shops scattered about West London. He had acquired the lease of Number 407, when the premises were given up by the late tenant, a clothier. He had never heard of Mr. Martin, and had certainly never written to him. He always signed himself John R. Lacey, and the signature on the letter found on Mr. Martin’s body bore no resemblance whatever to his handwriting. He had only once entered the cellars of Number 407, and had made no discoveries there of any kind. On Saturday he had left Liverpool Street at ten o’clock, to stay with his brother in Ipswich, and had not returned until the first train on Monday morning. He had sent no telephone message to Mr. Briggs, nor had he made any appointment with anybody to inspect the drains of Number 407. He had no key of the premises, having given the only two which so far as he knew existed to Houlder, the builder. He was utterly unable to throw any light whatever upon the incident, since more than a week had passed since he had visited Praed Street. + 

Two other facts did Inspector Whyland discover. The first, which did not astonish him, was that the letter signed John Lacey had in all probability been typed upon the same machine as had been the envelope in which the numbered counter had been sent to Richard Pargent. The second, which was distinctly perplexing, was that the call to Mr. Briggs had been made from a call-box at Aldersgate station, apparently at the very time when Mr. Martin was known to have been there. Lastly, the automatic was identified as the property of Mr. Martin, and a fingermark on the counter corresponded to an imprint taken from the dead man’s hand. + 

The significance of the curious butt found by the electrician in the lamp-holder was not so clear. It seemed reasonable to assume that nobody but the dead man had entered the premises after they had been locked by the foreman on Saturday morning. Whyland had examined all the doors and windows very carefully, and had satisfied himself that they bore no signs of violence. He could account for both keys, and although it was possible that a third key existed, it seemed unlikely that anyone had used it between 12:30 and two. Again, since the door had been found bolted on Monday morning, it was probable that the dead man had bolted it behind him, and that he was alone in the house when he died. The foreman had assured him that he had found the windows fastened inside, and that it was only by the use of a special tool that he had been enabled to open the one at the back. It looked very much as if Martin had himself fixed the butt in the lamp-holder. But why? + 

Certainly it looked very like a case of suicide. But against this theory was the letter found in the dead man’s pocket and the numbered counter. Martin himself might have deposited the latter, as the doctor had suggested, but would he have gone so far as to write a letter which must certainly put the police on the alert when it was found? It seemed highly improbable. Inspector Whyland felt convinced that the death of Mr. Martin was merely another link in the mysterious chain of murders in Praed Street. + 

The evening papers were, of course, full of it, though naturally somewhat guarded. “Another tragedy in Praed Street. City man found poisoned in Empty House”⁠—such was the general trend of their headlines. And Praed Street, which had begun to breathe again during the respite of the past month, felt once more the cold touch of almost superstitious horror. The killer was abroad again, unknown, unrecognized, and no man could tell when he might feel the dread hand of death upon his shoulder. + 

Inspector Whyland, walking through Praed Street that evening about ten o’clock, heard a cheerful voice bid him good evening, and turned to find Mr. Ludgrove by his side. + 

“Hullo, Mr. Ludgrove!” he exclaimed. “I called at your place just now, and found it shut up. I thought you were away.” + 

“I have been taking my usual evening stroll,” replied the herbalist. “Won’t you come in? I’m on my way home now.” + 

With scarcely a moment’s hesitation, Whyland accepted the invitation. There was always the chance that the herbalist might make some suggestion which would throw light on this latest problem. He waited until they were seated in the familiar back room before he asked the inevitable question. “You’ve heard what happened here this morning, I suppose?” + 

“I have, indeed,” replied Mr. Ludgrove gravely. “The papers contain little beyond the bare facts, but I gather that this unfortunate Mr. Martin was undoubtedly murdered?” + 

“I’m afraid so,” replied the Inspector. “And I fancy by the same hand which committed the previous murders. We found a typed letter on him, suggesting that he should call at Number 407, which had been posted in this district, and there was a counter bearing the number IV lying by his side. You don’t happen to know anything about this Mr. Martin, I suppose?” + 

Mr. Ludgrove shook his head. “I understand that he left Praed Street fifteen years ago,” he replied. “That was long before I came here. In those days I was leading a very quiet life in Devonshire.” He paused, and a curious look of sadness came into his eyes, as of some painful memory. Then he continued briskly, as if ashamed of his momentary lapse. “I daresay that Mr. Copperdock remembers him, he has a wonderful memory for everybody who has ever lived in the neighbourhood.” + 

Inspector Whyland’s eyes contracted slightly as he replied. “Yes, he remembers him all right. They did a certain amount of business together, he tells me. In fact, Mr. Copperdock is the only person about here who will admit to knowing anything about this fellow Martin.” + 

“Well, I suppose that we are all under suspicion once more,” said Mr. Ludgrove, with a kindly smile. “No, Inspector, it’s no use protesting; I know exactly how I should look at the matter if I were in your place. Until you have some definite clue to the perpetrator of the crimes, the whole neighbourhood is equally guilty in your eyes. I may say that I left here about one o’clock on Saturday, caught the 1:55 from Fenchurch, spent the day in Essex, and did not return until after dark. Not, I gather, that an alibi is much use in this case, since it appears that this Mr. Martin was alone in the house, in any event.” + 

“I wish everybody in Praed Street would deal with me as frankly as you have, Mr. Ludgrove,” replied Whyland. “There seems to be a sort of dread in the minds of most of them that the police will in some way take advantage of everything they say. Take Copperdock, for example. I’ve been talking to him, and he tells me he was at the Cambridge Arms for half an hour or so some time between one and two. Yet neither he nor his son will tell me exactly what time he left his shop or returned to it. They didn’t notice, they say.” + 

“Mr. Copperdock is not blessed with a very exact mind,” said Mr. Ludgrove soothingly. “You remember the curious incident of his meeting with the black sailor some time ago. By the way, I suppose that rather intangible person has not yet appeared in connection with the present case, has he? Although nearly everybody whom I have seen this evening has some theory to account for the facts, I have so far heard no reference to the black sailor.” + 

Inspector Whyland smiled as he rose to take his departure. “I’m so certain that the black sailor will never be found that I would willingly double the reward out of my own pocket,” he said. “He’s a myth, originating in the fertile imagination of that young scoundrel Wal Snyder. Well, good night, Mr. Ludgrove. Let me know if you hear any useful hint, won’t you?” + 

It was not until he was some yards down the street that he laughed shortly to himself. “That old chap suspects Copperdock as much as I do,” he muttered. “But if it is Copperdock, what the devil is his game, I wonder?” + 

At Scotland Yard + 

The experts to whom the curious device found by the electrician in the little cellar had been sent duly made their report. In their opinion, the butt was all that remained of an ingenious poison-bomb. The original machine consisted of a socket made to fit into an ordinary lamp-holder, but the place of the filament had been taken by a piece of fine wire, round which had been wrapped a thread of guncotton. Attached to the socket, and in contact with the guncotton, had been a sealed celluloid bulb containing pure prussic acid. + 

The action of such a bomb would be perfectly simple. It had only to be placed in a lamp-holder, and the switch turned on. The current would heat the fine wire, and so ignite the strand of guncotton. This in turn would set fire to the celluloid bulb, and its contents would be released in the form of vapour. Although some of this vapour would become ignited, enough would be available to permeate the atmosphere of a room far larger than the small cellar. And, of course, the inhalation of the vapour would rapidly produce death. + 

This opinion, the report stated, was purely speculative, since only the socket of the bomb remained for examination. Inspector Whyland, after consultation with his Chief at Scotland Yard, decided that it had better not be made public. The idea, though it was probably correct, was hypothetical, and altogether too vague to be put before a coroner’s jury. It certainly strengthened Whyland’s conviction that Mr. Martin had been murdered, for no man would go to the trouble of constructing an elaborate poison-bomb with which to kill himself when he might just as easily have inhaled the acid outright. When the electrician left the cellar on the Saturday the bomb had not been there. Whyland was convinced that the man was speaking the truth upon this point. The only two alternatives remaining were that somebody had entered the house between the departure of the foreman and the arrival of Mr. Martin, or that Martin had placed the bomb in position himself. The field of speculation opened by these alternatives was so vast and barren of any clue that their exploration must be a matter of considerable time. + 

As a matter of fact, the Assistant Commissioner was by no means convinced that Mr. Martin had been murdered. “We all know what a difficult job you’re up against in trying to trace the murders of these two fellows, Tovey and Pargent,” he said to Whyland in an interview to which he had summoned him, “But don’t you think you’re rather too much inclined to see the hand of the murderer in everything that happens in that district? Now, honestly, assuming that Martin was murdered, have you the slightest clue which could possibly lead to the conviction of the murderer?” + 

“No, sir, I haven’t,” replied Whyland. “But I’ve got my suspicions of this man Copperdock, whom I’ve mentioned to you.” + 

“Suspicions aren’t evidence,” said the Assistant Commissioner shortly. “Bring home the original murders to him by all means and then perhaps you’ll be able to link him up with the death of this man Martin. At present, so far as I can see, you’ll find it difficult to convince a jury that Martin was murdered. That poison-bomb theory is a bit farfetched, you must admit.” + 

“It is, rather, sir,” agreed Whyland. “Still we’ve got the letter and the numbered counter⁠—” + 

“It’s just that letter that worries me,” interrupted the Chief. “It was through the letter that you discovered that Martin was a receiver of stolen goods⁠—a very smart piece of work, Whyland, upon which I congratulate you. But, until we have rounded them all up, we don’t want the gentlemen with whom Martin dealt to become aware of our knowledge. If the existence of that letter becomes known, they’ll tumble to it at once. I should very much prefer the letter to be kept secret, for the present, at all events.” + 

The Assistant Commissioner paused, and Whyland glanced at him quickly. “I see no reason why it should be mentioned at the inquest, sir,” he said. “Nobody knows of its existence outside of the police.” + 

“Then I should be inclined to say nothing about it,” remarked the Assistant Commissioner. “Nor, I imagine, will it be necessary to bring into prominence the hypothesis of the poison-bomb, or the fact that you have any suspicions of foul play. I am not suggesting that you should wilfully mislead the coroner, mind. But it is usually a mistake to volunteer information when no useful purpose can be served by so doing.” + 

So it happened that the doctor’s evidence at the inquest remained unchallenged. The theory was that Martin, having decided to take his own life, was attracted to his old premises knowing them to be empty. In order to obtain access, he telephoned himself from Aldersgate station to Mr. Briggs, using Mr. Lacey’s name. Having thus secured the key, he bolted the door behind him to prevent any interruption, then went into the cellar and inhaled the vapour of prussic acid. The automatic he had brought with him in the case the poison should prove ineffective. The numbered counter, which he had also brought with him, as the fingermarks upon it showed, merely emphasized the morbid state of mind which had prompted him to the deed. + 

The jury returned a verdict of suicide during temporary insanity, in accordance with this theory, and, to all outward appearances the case of Mr. Martin was disposed of. But Inspector Whyland, although relieved to feel that yet another unsolved crime had not been added to his already mounting debit account, knew well enough at heart that once again his mysterious adversary had scored a point against him. But again, there was this insoluble riddle of motive. It was possible to suggest more than one motive for the murder of Mr. Martin. He might, for instance, have fallen out with one of the jewel thieves with whom he had such intimate relations. Or again, his dealings with women might have been at the bottom of it. But, assuming one of these suppositions to be correct, how was the death of Mr. Martin to be linked with the previous murders? Or were they indeed all the work of separate persons, who imitated one another’s methods with a view to confusing the issue? + 

Inspector Whyland recalled his mind from such unprofitable speculations. He felt that the solution of the whole mystery lay close under his hand, if he could but devise the means to unearth it. Somehow Mr. Copperdock’s name always came up in connection with these murders. He had been Tovey’s most intimate friend. The pipe which had been the cause of Colburn’s death had been bought at his shop. He must have been within a few yards of the scene when Pargent was murdered. And Whyland had no doubt that he would discover some point of contact between Mr. Copperdock and the present case. + 

He was not disappointed. It came out, in the course of a conversation between him and Houlder, the builder. It seemed that Houlder, who was an occasional frequenter of the Cambridge Arms, had mentioned, early in the month, that a new tenant had taken Number 407, and that he had got the job of altering the premises for him. Mr. Copperdock had displayed great interest in this remark, and as a result Houlder had invited him to come and look over the place. Mr. Copperdock had accepted, and he and Houlder had been over every inch of it. This might have been pure curiosity on Mr. Copperdock’s part, but at least the fact was significant. Inspector Whyland stored it in the mental pigeonhole which already contained the note that Martin and Copperdock had done considerable business together in the past. + 

Thus, putting the case mathematically, Mr. Copperdock was the highest common factor of the terms representing the four dead men. Inspector Whyland had spent much time and care in investigating their histories and their actions, and he could find no other factor common to them all. They had been, so far as he had been able to ascertain, complete strangers to one another, and they could never consciously have met one another. The only characteristics which they had in common were that they had all received counters numbered in the order of their deaths, that they were all males, and that their ages had all been over fifty. + 

Naturally, the mind of Praed Street was not greatly relieved by the verdict on the death of Mr. Martin. Violent death was becoming far too frequent an incident for any of the local community to feel safe. Men wondered when it would be their turn to find the fatal counter, and how they should ward off the death which so swiftly followed. It was not as though one could tell exactly what one had to guard against. The knife had been used twice, certainly, but poison in one form or another had accounted for two of the deaths. + 

The numbered counters were the characteristic feature of the case which appealed most strongly to the popular imagination. Inexplicable murders were common enough, even murders in which no motive or criminal had ever been found. But a series of murders, each prefixed by a definite warning, were an entirely novel sensation. The theory of the counters was publicly discussed from every possible point of view, without any really satisfactory theory being arrived at. Quite a large proportion of the population of London opened their morning papers in expectation of finding news of the delivery of counter number V. + 

The news, when it came, illustrated the hold which the subject had upon men’s minds, and the moral effect which it has produced. Mr. Ludgrove read the story as he consumed his frugal breakfast, and he was not surprised to hear Mr. Copperdock’s voice in the shop a few minutes later. + 

“Come in, Mr. Copperdock,” he called, and the tobacconist, paper in hand, the light of excitement in his eyes, entered through the curtained door. + 

“Have you seen this about this old chap Goodwin?” he enquired, without preliminary. + 

“I have indeed,” replied Mr. Ludgrove gravely. “I imagine that the whole thing was an utterly heartless practical joke. I only hope the police will be able to trace the sender.” + 

“Aye, practical joke, maybe, but it killed him all the same,” said Mr. Copperdock doubtfully. “Fancy an old chap like that, what couldn’t have had more than a year or two to live! The paper says that he couldn’t even walk from one room to another, had to be wheeled in a chair. This daughter of his what was looking after him says here that the doctor had told her that any shock might be fatal. Wonder if she sent it herself, being tired of waiting for his money? Listen, this is what she says: ‘My father’s chief amusement was to read the papers. He took the keenest interest in every item of news, and often discussed them with me. We often talked about the murders which have taken place recently in Praed Street, and my father always maintained that the curious episode of the numbered counters proved that they were not the work of a maniac.’ ” + 

“Yes. It is easy to understand what a shock the receipt of the counter must have been to him,” replied Mr. Ludgrove reflectively. “It would be interesting to know who, besides his daughter, knew of this passion for news on his part. I see by the account in my paper that three letters arrived for him by the morning post, and that his daughter brought them in to him on his breakfast tray. He opened the first one, and a counter numbered V fell out of it.” + 

“Then he fell back on his pillow and never spoke again,” put in Mr. Copperdock excitedly. “The shock killed him right enough, as the doctors had said it would. I wouldn’t like to be in the shoes of the person what sent it him.” + 

Mr. Ludgrove glanced at his friend sharply. “I cannot understand it, except upon the assumption of a practical joke, and a particularly cruel one at that,” he said. “Here was this Mr. Goodwin, a retired manufacturer, who had been living in this house at Highgate for many years past. All his acquaintances knew that his heart was very seriously affected, and that he had only a short time to live. Of course, we know nothing of his past history, but, whatever motive there may have been, to murder a man in his condition would merely be to anticipate the course of nature by a few months. And, in our experience, the receipt of the counter has always been followed by violent death. I say we know nothing about him; I certainly do not. I suppose that you have never heard of him before, have you, Mr. Copperdock?” + 

Mr. Copperdock shook his head. “Never!” he replied emphatically. “Seems to me it’s just like that poet chap, Pargent. Somebody sends him the counter, and his number’s up. Well thank heaven, it didn’t happen in Praed Street, this time.” + 

It was not long after Mr. Copperdock’s departure that Inspector Whyland came in to see the herbalist. He said nothing, but glanced at Mr. Ludgrove enquiringly. + 

“Yes, I’ve seen it in the paper,” said Mr. Ludgrove. “As a matter of fact, I’ve just been discussing it with Mr. Copperdock. He came over here as soon as he read about it.” + 

“Oh, he did, did he?” replied Whyland. “And what do you make of it, may I ask?” + 

Mr. Ludgrove shrugged his shoulders. “I know no more than what the paper contains,” he said. “It looks to me like a practical joke. I shouldn’t wonder if some idiot derives amusement from sending these counters broadcast. I daresay he gets the names of people to send them to from the telephone directory.” + 

“Practical joke? H’m,” said Whyland. “Mind, I’m not denying that a lot of fools do send out these counters to their friends. The Yard has had dozens of cases reported to them. I always said that would happen as soon as people heard about them. But in this case I have seen the envelope in which the counter was sent. It was typed on the same machine as the others, and it was posted in this district, exactly as the others were. Your practical joker has followed his original model pretty closely, don’t you think?” + 

The ardent seekers after sensation redoubled their eagerness for news of the next counter. Although opinion on the whole followed Mr. Ludgrove in attributing the counter sent to Mr. Goodwin to some irresponsible practical joker, the fact that death had undoubtedly followed its receipt caused many to shake their heads knowingly. If Mr. Martin’s death had been due to suicide, and Mr. Goodwin’s to a practical joke, how would the original sender of the counters number his next one? It was not to be supposed that he would claim credit for these spurious imitations of his work. If the next number were to be VI, public opinion was quite prepared to credit him with having compassed the last two deaths. But most people anticipated that it would bear the number IV. + 

The fact that such discussion was possible showed clearly that the theory of the existence of some mysterious assassin had captured the popular imagination. There was really no reason why any murderer should not send a numbered counter to his prospective victim, but people argued, quite correctly, that murders were far more often the result of sudden impulse than of deliberate intention. It was for this reason that the “counter deaths” as they were sometimes called, attracted so much attention. Yet the weeks drew into months, and the cold winds of spring took the place of the misty drizzle of winter, without any news of another numbered counter being received. The armchair criminologists gave it as their opinion that the last had been heard of them, that the mysterious criminal had either fulfilled his vengeance or had died unrecognized in some lunatic asylum. The murders in Praed Street were added to the long list of undiscovered crimes, and slowly they began to be forgotten. + 

One evening towards the end of April, Mr. Copperdock was sitting in the herbalist’s back room, enjoying a generous whiskey and soda. He was on his way home from the Cambridge Arms, and, seeing his friend’s door still open, had looked in for a chat. The night was warm, one of those nights which London sometimes experiences in early spring, conveying the promise, so rarely fulfilled, of a fine summer. + 

The liquor which he had consumed made Mr. Copperdock even more communicative than usual. Some reference to his son had led him on to speak of Ivy, and thus, by a simple association of ideas, to the murder of Mr. Tovey. + 

“You know, Ludgrove, that fellow Whyland always suspected me of having to do with that business,” he said. “I don’t believe he’s satisfied yet, between ourselves. At one time he was always hanging about, coming into my place at all hours, and asking all sorts of questions. I used to see chaps lounging about outside, and sometimes they followed me when I went out. It was jolly uncomfortable, I can tell you.” + 

Mr. Ludgrove smiled. “I don’t suppose you were any more under suspicion than the rest of us,” he replied. “Whyland had an idea that somebody in this neighbourhood was responsible, and I don’t know that I don’t agree with him. He came in here, too, and asked questions, for that matter. For all I know he may have suspected me.” + 

But Mr. Copperdock shook his head. “No, Ludgrove, that won’t do,” he said. “There was something about the way he spoke to me that gave him away. He still comes in sometimes, and asks me all sorts of questions about those poor fellows who were killed. Very often they’re the same things as he’s asked before. Trying to catch me out, I suppose. And he’s always asking if I’ve ever seen the black sailor again.” + 

“I suppose you really did see him?” asked Mr. Ludgrove casually. + 

“See him? I saw him as plain as I see you now,” replied Mr. Copperdock, with some indignation. “What would I want to say I’d seen him for if I hadn’t? I wish now I’d never said anything about it. I wouldn’t have, but I thought it would be doing Whyland a good turn.” + 

“Well, it’s all over now,” said Mr. Ludgrove soothingly. “We haven’t had any of these mysterious deaths for nearly three months now. I don’t expect that Inspector Whyland will worry his head about the matter much longer.” + 

“I hope he won’t,” replied Mr. Copperdock truculently. “I’ll give him a piece of mind if he comes round worrying me much more. I’m as respectable a man as any in this street, I’d have him know.” + 

He finished his drink, and rose to go. Mr. Ludgrove saw him off the premises, then settled himself down once more in his chair to read. + 

Five minutes later he heard a heavy step hurrying through the shop, and the form of Mr. Copperdock appeared unceremoniously through the curtain that covered the door of the inner room. Mr. Ludgrove rose to his feet in concern. The tobacconist’s face was deathly pale, and his hands were trembling violently. He staggered across the room, and sank down into the chair he had so lately quitted. + 

He held out one shaking hand open towards the herbalist. “Here, look at this!” he exclaimed in a queer hoarse voice. + 

The herbalist bent over the outstretched hand. In the palm of it lay a white counter, upon which the figure VI had been roughly drawn in red ink. + 

XI + 

The Sixth Counter + 

Mr. Ludgrove looked at the counter and then raised his eyes to Mr. Copperdock’s face. The tobacconist was staring at him with an expression of complete bewilderment and terror, very different from his truculent demeanour of a few minutes earlier. The herbalist checked the slow smile which had begun to twitch the corner of his lips, and sat down quietly opposite Mr. Copperdock. + 

“Where did you find this?” he asked. + 

“On my bed, after I left you just now,” replied the tobacconist. “It wasn’t there when I went out to the Cambridge Arms this evening, I’ll swear. I always goes upstairs to have a wash before I goes out, and I’d have been bound to have seen it. It’s that black sailor. I always thought he’d get me.” + 

“Well, he hasn’t got you yet,” said Mr. Ludgrove soothingly. “Now that you have been warned, we can take the proper precautions. How do you suppose this counter came into your room?” + 

Mr. Copperdock shook his head helplessly. “It beats me,” he replied. “I locked the door behind me when I went out, and nobody couldn’t have got in till I went back just now, seeing as I had the key in my pocket all the time.” + 

“You locked the door when you went out? Was Ted out, too, then?” + 

“Yes, Ted and I went out together, about half-past eight. He was going to spend the evening with the Toveys. I don’t expect him back till nigh on eleven. I goes round to the Cambridge Arms, where I stays until I comes in to you just now. And when I gets back, there was this counter, right in the middle of my bed. I just picks it up and comes over to you. I daren’t stay no longer in the house alone.” + 

“You didn’t notice if anything else in the house had been disturbed, I suppose?” + 

“I didn’t stop to look. It gave me such a turn seeing that thing there, I didn’t hardly know what I was doing.” + 

“Well, you’d better stay here until your son comes back,” said Mr. Ludgrove. “It is very nearly eleven now. I suppose you shut the door behind you when you came over here? How will Ted get in?” + 

“We both has our keys,” replied Mr. Copperdock. “Ted’s a good boy. I wouldn’t have minded so much if he’d been there.” + 

“Well, I’ll go to the door and watch for him,” said Mr. Ludgrove cheerfully. “You’ll be all right here, Mr. Copperdock.” + 

“Don’t you go no further than the door!” exclaimed the tobacconist fearfully. “For all I know that black sailor chap may be on the lookout, and seen me come across here. He’ll get me, for sure.” + 

“He won’t get you here, I promise you,” said Mr. Ludgrove reassuringly. He mixed a strong whiskey and water, and placed it in the trembling hand of his guest. “You drink this while I go into the shop and keep an eye open for your son.” + 

Mr. Ludgrove had not been at his post for many minutes before Ted came swinging along the opposite pavement. He stopped at the sound of the herbalist’s voice, and crossed the road towards him. In a few whispered words Mr. Ludgrove acquainted him with what had happened. + 

Ted said nothing, but jerked his elbow upwards and winked suggestively. + 

“No, I don’t think so,” said Mr. Ludgrove. “But you had better come in and talk to him.” + 

The two entered the back room together, and Mr. Copperdock looked up anxiously as they came in. + 

“Ah, Ted, my boy, I’m glad to see you,” he said dolefully. “The black sailor’s on my track, and he’ll get me, for sure.” + 

“Nonsense, Dad,” replied Ted heartily. “Somebody put that counter on your bed for a joke; one of your pals at the Cambridge Arms, I’ll be bound. You come along home with me, and we’ll soon find out who it was.” + 

But Mr. Copperdock shook his head. “I wouldn’t go into that house again not tonight, no, not if you was to pay me,” he replied firmly. “I’d sooner go and spend the night at the police station.” + 

“You needn’t do that,” said Mr. Ludgrove. “You can spend the night here on my bed upstairs. I have no objection to sleeping on the chair.” + 

“I daren’t be left alone,” lamented Mr. Copperdock. “Anybody might have seen me cross the road and come in here. Do you think Inspector Whyland would send a couple of coppers along if Ted was to ring him up? I’d feel a lot safer if they was about.” + 

“I hardly think he would,” replied Mr. Ludgrove. “But if you like we will spend the night together in this room. You can have one chair, and I will have the other. I can put a mattress on the floor for Ted if he cares to join us.” + 

“Not I, I’m going home to bed,” put in Ted heartily, with a wink at the herbalist. “Somebody ought to be on guard over at our place in case the black sailor breaks in, you know, Dad.” + 

Rather reluctantly Mr. Copperdock agreed to this arrangement. After a few more minutes’ conversation, Ted went home, and the two settled themselves down in the chairs. A further strong whiskey and water produced its effect upon Mr. Copperdock, and he was very soon dozing restlessly. To Mr. Ludgrove sleep seemed an unnecessary luxury. He moved quietly over to his bench, and spent the greater part of the night absorbed in his herbs and his microscope, apparently entirely oblivious of the presence of his guest. The only sign he manifested of interest in his affairs was to pick up the counter and examine it very carefully through a powerful lens. + 

It was not until seven o’clock in the morning that he gently shook the sleeping form. Mr. Copperdock woke with a start, and stared about him with puzzled eyes. + 

“I’ve got a cup of tea ready for you, Mr. Copperdock,” said the herbalist. “I thought it was time to wake you, as Mrs. Cooper will be here presently, and if she found you here she might talk. We don’t want that, do we?” + 

The tobacconist rose stiffly to his feet and shook himself. “Very kind of you, I’m sure, Ludgrove,” he said. “Yes, I remember. What did you do with that counter?” + 

“I have it here,” replied the herbalist. “You are still quite sure that you found it on your bed last night? It wasn’t by any chance slipped into your pocket by somebody at the Cambridge Arms?” + 

“As sure as I live. I found it on my bed, same as I told you,” affirmed Mr. Copperdock earnestly. “I wasn’t tight last night, if that’s what you’re getting at.” + 

“No, no, of course not,” replied Mr. Ludgrove soothingly. “Now, shall we go across and see if your son heard anything during the night?” + 

Mr. Copperdock agreeing, they crossed the road to the tobacconist’s shop, and let themselves in. Ted was still asleep, and they had some difficulty in waking him. When they had done so, he reported that he had had a good look round the place before he went to bed, and had found nothing unusual. After that⁠—well, he had gone to sleep, and had heard nothing until they had awakened him. + 

The light of morning appeared to have instilled rather more courage into Mr. Copperdock’s heart. He announced his determination to carry on business as usual, but insisted that Inspector Whyland should be communicated with and told of his discovery of the numbered counter. It was about ten o’clock when Whyland arrived in Praed Street, but instead of going straight to Copperdock’s shop, he went first to the herbalist’s. + 

“What’s this story about Copperdock having found a numbered counter?” he asked, as soon as they were safely hidden in the back room from prying ears. + 

Mr. Ludgrove recounted his experiences of the past night, and as he came to a conclusion Whyland laughed contemptuously. “Is this another of Copperdock’s hallucinations, like that meeting of his with the black sailor?” he enquired. + 

“Not altogether,” replied Mr. Ludgrove with a smile. “The counter is real enough, at all events. He left it here last night. Here it is.” + 

Whyland examined the counter in silence. He had very little doubt that Mr. Copperdock had staged the whole affair, had written the figure VI upon it in red ink himself, and had placed it on his bed. But why? What was his game? Was this a feeble scheme to draw suspicion from himself? The series of murders appeared to have come to an end. What was the point of reviving the memory of them like this? + 

Mr. Ludgrove broke in upon his meditations. “I took the liberty of examining it under a powerful glass,” he said, nodding his head towards the bench. “It seems to be an ordinary bone counter and the figure VI has been drawn upon it with a steel pen and red ink.” + 

“Just as the others were,” agreed Whyland. “I’ll keep this counter, if you don’t mind. I want to add it to my collection. Now I suppose I had better step across and see Copperdock. I should like you to come with me, if you can spare the time.” + 

“I think I can risk shutting the shop for a few minutes,” replied the herbalist. “I get very few customers in the morning. Most of the people who require my services are at work all day.” + 

“Dishonest work, I’ll be bound,” said Whyland chaffingly. “Well, come along, then.” + 

They went across to Mr. Copperdock’s shop together, and were shown by the tobacconist into the room behind the shop, which was used as an office. At one side was a table upon which stood a Planet typewriter, at the other a desk. Inspector Whyland seated himself at the latter, selected one of the pens before him, and dipped it into an inkpot, which happened to contain red ink. + 

“Now then, Mr. Copperdock,” he said. “Tell me exactly what happened yesterday evening.” + 

The tobacconist immediately launched into an account of his adventure. Whyland listened patiently, occasionally making a brief note with the pen. “You say that nobody could have entered the house while you were out?” he asked, as Mr. Copperdock came to the end of his story. + 

“Quite impossible,” replied Mr. Copperdock emphatically. “There’s only one door, with a spring lock which catches when you shuts it.” + 

“H’m. I’d like to have a look round, if you don’t mind,” said the Inspector. + 

He examined the house carefully. On the ground floor was the shop, and behind it the office and a little kitchen containing a gas stove. The windows of these did not open, and were high up in the wall, and covered with a stout iron grating. There was no back entrance. From a narrow passage a staircase ran up to the first floor, upon which were two bedrooms, occupied respectively by Mr. Copperdock and his son, and a sitting-room. The bedrooms were over the shop, and looked out upon Praed Street. The sitting-room was at the back, and looked out over an enclosed yard, belonging to a transport contractor, and used for storing vans at night. The windows on the first floor were obviously inaccessible without the aid of a ladder. Above the first floor were a couple of attics, lighted only by skylights, which were closed and padlocked. From the cobwebs which covered them, it was obvious that they had not been opened for a long time. + 

Inspector Whyland returned to the first floor. “Were these windows closed and fastened while you were out last night?” he enquired. + 

“The sitting-room was,” replied Ted, who had followed them upstairs. “I looked at it when I came in. It hasn’t been touched since.” + 

Whyland looked at it, and satisfied himself that it showed no signs of having been forced. “What about the bedroom windows?” he asked. + 

“Both Dad’s and mine were open at the top,” replied Ted. “But nobody could have got in through them, unless they had put up a ladder in the middle of Praed Street.” + 

“Even the black sailor isn’t likely to have done that,” observed Whyland sarcastically. “Well, Mr. Copperdock, the best advice I can give you is not to go about alone at night too much. I’ll have a man watch outside the premises for a bit, if that’s any comfort to you. But, if you ask me, I don’t think you’re in any immediate danger.” + 

It seemed that the Inspector was right. Several days passed without anything untoward happening to Mr. Copperdock. The tobacconist resumed his normal routine, with the modification that he took care never to be alone. His son walked with him as far as the Cambridge Arms, and one at least of his cronies there walked back with him to the shop. Mr. Ludgrove, watching with some amusement, recognized every night the watcher that Whyland had promised to provide. It struck him that the man’s instructions were probably to keep an eye on Mr. Copperdock’s movements rather than to provide for his safety. But upon the tobacconist, who, now he had got over his fright, appeared to regard himself as something of a hero, the man’s presence produced an impression of importance and of security. + 

The only aspect of the incident which appealed to Whyland was the counter itself. He had submitted it to the experts at Scotland Yard, together with the notes which he had made in red ink in Mr. Copperdock’s office, and they had given it as their opinion that the figure upon it had been drawn with the same ink as that in which the notes had been written, and by a similar pen. Further, this pen and ink corresponded with those which had been used on the previous counters, in the cases in which they had been preserved. The more the Inspector considered it, the more convinced he became that Mr. Copperdock was at the bottom of the business. But how to bring it home to him? That was the difficulty. + 

Mr. Copperdock had found the numbered counter on Tuesday evening. On the following Saturday Ted had arranged to take Ivy to a dance, from which he was not likely to return until after midnight. It had been suggested that Mr. Copperdock, in order that he should not be left alone, should spend the time between the closing of the Cambridge Arms and the return of his son in Mr. Ludgrove’s sanctum. + 

But, deriving courage from the fact that four days had elapsed without anything happening, Mr. Copperdock refused to consider any such proposal. He must have detected the general scepticism with which his story of the finding of the counter had been received, and had resolved to say no more about it. He went to the Cambridge Arms at his usual hour, stayed there until closing time, and was then accompanied home by two friends of his, who lived in the Edgware Road, and who had to pass the door on their way home. He invited these two to come in and have a last drink with him, and they accepted, on the grounds that it was a beautiful night, and very thirsty work walking. + 

The story of the finding of the counter was by this time familiar to all the clientele of the Cambridge Arms, each individual member of which suspected some other member of having somehow conveyed it into Mr. Copperdock’s possession. It was absurd to think, as one of them remarked in his absence, that anybody could have a grudge against Sam Copperdock. Somebody must be pulling his leg, that was the only possible explanation. It was with some considerable interest, therefore, that his two friends followed the tobacconist as he took them into his bedroom and showed them the exact place where he found the counter. + 

It was not until nearly eleven that Mr. Copperdock’s party broke up. Inspector Whyland’s deputy, strolling past on the other side of the road, noticed the parting on the doorstep, and observed that after the departure of his friends, Mr. Copperdock shut the door of his shop. A few minutes later he saw a light switched on in one of the front rooms upstairs. This he knew, from his experience of previous nights, was the signal that Mr. Copperdock was going to bed. + 

Mr. Ludgrove, since the tobacconist had refused his offer of hospitality, spent the evening by himself. The room above his shop was littered with innumerable boxes containing all manner of dried herbs and similar items of the stock-in-trade of his calling. He spent several hours between that room and his sanctum. His work bench became strewed with specimens to which from time to time he affixed labels with high-sounding names. The door of his shop was ajar until about half-past ten, up till which hour an occasional customer interrupted his labours. After that time it was closed, and he was able to devote his whole attention to his plants. + 

He was still working at midnight. He appeared to require very little sleep, and rarely went to bed before the early hours of the morning. He had just brewed himself a cup of his favourite cocoa, when suddenly he heard a violent hammering upon the door of the shop. Instinctively he glanced at the clock upon the mantelpiece. The hands pointed to twenty minutes past twelve. + 

Surely no customer could be seeking admittance at such an hour! Besides, the knocking was clamorous, insistent, not in the least like the furtive taps which usually proclaimed the visit of some client, anxious to hide his errand under the cover of darkness. With a shrug of his shoulders Mr. Ludgrove put down his cup and went to the door. He drew back the bolts and put out his head, to find Ted Copperdock standing on the pavement outside. + 

The young man gave him no chance to ask questions. He threw out his hand and caught Mr. Ludgrove by the arm, as though to drag him forcibly into the street. “For God’s sake come and see Dad!” he exclaimed. + 

“Why, what has happened?” enquired Mr. Ludgrove quickly. + 

“I don’t know, he’s dead, I think,” replied Ted incoherently. “I’ve just come back and found him. Something terrible’s happened⁠—” + 

Mr. Ludgrove was not the man to be carried off his feet by a sudden crisis. “Certainly, Ted, I’ll come over,” he said quietly. “But you appear to want a doctor rather than me. You probably know that a detective has been patrolling the streets for the last few nights. I think I see him coming towards us now. You go and fetch the doctor, while he and I attend to your father.” + 

Ted, after a moment’s hesitation, ran off down the road, and Mr. Ludgrove walked swiftly towards the advancing figure, which he had already recognized. “Something has happened to Mr. Copperdock,” he said as he reached him. “I have sent his son for a doctor, and said that you and I would go in.” + 

“Something happened, eh?” replied the man, as the two strode swiftly towards the door of the tobacconist’s shop. “You don’t know what it is, I suppose? I’ve had my eye on the place all the evening, and there’s been nobody near it between eleven, when two fellows whom Copperdock took in came out, and five minutes ago, when his son let himself in with a key. And there’s been a light in the front window upstairs all that time.” + 

“No, I know nothing,” replied Mr. Ludgrove anxiously. They had reached the shop by this time. The door had been left open by Ted in his haste to call the herbalist, and they hurried on through the shop and up the staircase to the first floor. The door of Mr. Copperdock’s bedroom stood open, and they rushed in together. On the threshold they halted, moved by a simultaneous impulse. Before them, in the middle of the floor, lay Mr. Copperdock, stripped to the waist, with an expression of innocent surprise upon his face. + 

XII + 

A Hypodermic Needle + 

For a moment the two men stood still, rooted to the ground with horror. Then Mr. Ludgrove stepped forward and fell on his knees by Mr. Copperdock’s side. He put his finger on his wrist for a moment, then slowly rose to his feet and shook his head. + 

“Dead?” said the detective enquiringly. “By jove, this is a bad business. Will you stay here for a moment while I go down into the shop and telephone? I’ll ring up the station and get them to send for Whyland. Don’t touch anything, whatever you do.” + 

Mr. Ludgrove nodded. He stood motionless in the doorway when voices below proclaimed the arrival on the scene of Ted and the doctor. The detective, who had sent his message, came upstairs with them, and the three joined Mr. Ludgrove. + 

The doctor took in the situation at a glance. Mr. Copperdock was lying on his back, his legs drawn up close to his body. The doctor examined him in silence for awhile, then beckoned to the detective. + 

“I don’t understand this at all,” he said. “I shall have to make a more thorough examination than is possible while he is lying in this position. I’m afraid there’s nothing to be done. I don’t want to move him until your Inspector comes. He won’t be long, I suppose?” + 

“He’s living close to the station,” replied the detective. “They’ve sent a man with a motorcycle and sidecar round to fetch him and bring him here. It oughtn’t to take him more than a few minutes. I’d rather you waited, if you don’t mind.” + 

The doctor nodded and continued his examination, while the other three stood where they were, looking keenly about them. It was obvious that when death overtook Mr. Copperdock he had been preparing for bed. His coat, waistcoat, shirt and vest lay on a chair, and the basin on the washing stand was half full of soapy water. A towel lay on the floor near it. + 

The minutes seemed to pass with leaden slowness until a faint throbbing reached their ears, which rapidly grew in intensity until it resolved itself into the sound of a motorcycle. The noise ceased suddenly as it reached the door, and in a few seconds Inspector Whyland appeared, half dressed, with a stern expression on his face. + 

“How did this happen, Waters?” he enquired sharply, turning to the detective. + 

“I don’t know, sir,” replied the latter. “I’ve been watching the house all the evening⁠—” + 

“Well, never mind, you can tell me about that later,” interrupted Whyland. “Good evening, doctor. Can you tell me what this man died of?” + 

“No, I can’t” replied the doctor. “It looks as if he had been bitten by a snake, or something of that kind. I was waiting till you came to make a thorough examination.” + 

“Right. Stand fast a minute while I look round.” He made a swift survey of the room, then, taking a piece of chalk from his pocket, marked on the carpet the position in which the body was lying. + 

“Now then, doctor, I’m ready,” he said. “What do you want to do?” + 

“I want him laid on his side, if you’ll bear a hand,” replied the doctor. “That’s right. Hullo, look at that!” + 

They had moved Mr. Copperdock’s body until his back was visible. There, just below the left shoulder-blade, was an almost circular patch, covered with a curious white powdery incrustation. In the centre of this patch was an angry looking purple spot. + 

The doctor bent over this and uttered an exclamation of amazement. Opening the case which he had laid down by his side he took from it a pair of forceps, and applied them to the spot on Mr. Copperdock’s back. From this he withdrew something, which he carried over to the light, and beckoned to Whyland to inspect. + 

“See that?” he said. “That’s the end of a fine hypodermic needle. I’m beginning to see what happened, now. He was injected with some powerful toxic agent by means of a hypodermic syringe, the needle of which broke off in the process. The nature of the poison we shall be able to determine by an examination of this fragment. But I don’t understand that white incrustation. Let me have another look at it.” + 

He selected a small phial from his case, put the fragment of the needle into it, and labelled it. Then he turned once more to Mr. Copperdock’s body, and examined the patch once more with a lens. Finally he removed some of the white powder and put it in another phial, which he also sealed and labelled. + 

Then he beckoned Whyland aside, and the two conversed for a moment in low whispers. + 

“This is really most extraordinary,” said the doctor. “This man undoubtedly died from an injection of poison administered hypodermically. You remember the case of Colburn, the baker, last year?” + 

“Yes, I remember it well,” replied Whyland. “What about it, doctor?” + 

“Well, of course, I can’t say definitely as yet,” replied the doctor guardedly. “But it seems to me that the symptoms in the two cases are remarkably similar. I would go so far as to hazard the opinion that the same poison was employed in both cases. Now, in the present case, you, I take it, are chiefly interested in the agency by which the poison was administered. Well, it is possible that in this case it was self-administered. One can just manage to run a hypodermic needle into oneself below the left shoulder-blade. Here’s a syringe. There’s no needle in it. Hold it in your left hand. That’s right. Now, see if you can press the nozzle against your back in the place corresponding to the spot on Mr. Copperdock’s body.” + 

Whyland obeyed, and after some fumbling contrived to reach the exact spot. “Yes, it can be done, but it’s precious awkward,” he remarked, handing the syringe back. + 

“Exactly,” agreed the doctor. “That may account for the needle having broken off. Mind, I’m only suggesting a possibility, not laying down a theory. That’s your job. Now we come to the white incrustation round the puncture. Unless I’m greatly mistaken, it is potassium carbonate. Should it prove to be so, the fact would be of considerable significance.” + 

“Why?” enquired Whyland. “I’m afraid I don’t quite follow you, doctor.” + 

“Potassium carbonate has no particular properties of its own,” replied the doctor. “But, if a piece of caustic potash had been applied to the puncture, say an hour or two ago, it would by now have been converted into potassium carbonate. You see what this suggests. Caustic substances are employed to burn out poisoned surfaces. In this case, caustic potash may have been employed in an attempt to counteract the poison. Of course, it would be ineffectual, as it had been injected far too deeply. But that it has been so applied I am pretty certain. You can see for yourself that the skin shows traces of burning under the incrustation. Whether the same hand that injected the poison applied this ineffectual antidote, I cannot say.” + 

Whyland nodded, and then a sudden thought struck him. “But look here, if he injected the poison himself, the syringe ought to be lying about somewhere!” he exclaimed. “How long would it take for the poison to act, doctor?” + 

The doctor shook his head. “I can’t say, since I do not yet know its nature,” he replied. “If it was the same as was employed in Colburn’s case, we can make a rough guess, however. A very small quantity, applied to a scratch in his tongue, caused death in two hours and a half. We may assume that very much larger quantity would be contained in a syringe, and it was driven well into the tissues. Death might well have occurred within a few minutes. But in any case, there would have been time to dispose of the syringe.” + 

The doctor turned and pointed to the window. “That’s open at the top, as you see, and the curtains do not meet by a couple of feet or more. He could have thrown it out there without the slightest difficulty.” + 

Whyland turned to the three men, who had been standing by the door. “Slip down below, Waters, and search the pavement and roadway outside this window for a hypodermic syringe,” he said. “Sharp, now! Mr. Ludgrove, come to this window for a moment; you know this street better than I do. That’s your place opposite, isn’t it? What’s behind that window over the shop?” + 

“A room I use for storing herbs in,” replied Mr. Ludgrove. “As it happens, I have been in there once or twice this evening.” + 

“You didn’t see anything of what was happening in here, I suppose?” asked Whyland quickly. + 

“No, I did not,” replied Mr. Ludgrove. “I was only in the room for a moment or two, selecting bundles of herbs to take downstairs. I did happen to notice about eleven o’clock that there was a light in here, but that was all.” + 

“What about the windows to the right and left of your place?” + 

“I believe that they belong to offices occupied only in the daytime. I do not think it at all likely that anyone could have overlooked this room from them at night.” + 

“No,” agreed Whyland. “We’re not likely to be lucky to find an actual witness. All right, Mr. Ludgrove, thank you. Now, young man, do you know if your father possessed a hypodermic syringe?” + 

Ted Copperdock, thus addressed, shook his head. “I don’t think so, Inspector,” he replied. “But I shouldn’t know one if I saw it. There’s a cupboard over there by the washing stand where he kept a lot of bottles of stuff.” + 

Whyland strode over to the cupboard and opened it. It contained about a dozen bottles of various sizes, each half full of some patent medicine or other. But of a hypodermic syringe, or even any caustic potash, there was no trace. + 

“If he did it himself he must have thrown the syringe away,” muttered Whyland. “Waters ought to find it; there isn’t a lot of traffic along here at this time of night. Well, doctor, I don’t think we need keep you out of bed any longer. I’ll have the body taken to the mortuary, and perhaps you’ll ring me up at the station later in the morning?” + 

The doctor nodded, picked up his bag, which contained the broken needle and the sample of the incrustation, and left the house. When he had gone, Whyland turned once again to Ted. + 

“Can you suggest any reason why your father should wish to take his life?” he enquired. + 

“No, Inspector, I can’t,” replied Ted frankly. “The business is doing very well, and father was only saying the other day that we’d got a tidy bit put away in the bank. I keep the books myself, and I know everything’s all right.” + 

“I see. No money troubles, in fact. You don’t know of any disappointment which he may have experienced, or anything like that?” + 

A faint smile passed across Ted’s face. “I don’t think he had any disappointment, Inspector,” he replied. “In fact, I should say it was rather the other way.” + 

“What do you mean?” said Whyland sharply. + 

“Why, he always reckoned that nobody knew, but I fancy that we all guessed sharp enough. He’s hinted to me once or twice lately that he wasn’t too old to marry again. And⁠—well, from what her daughter lets drop, Mrs. Tovey wouldn’t mind. He went round there pretty often, and she always seemed glad to see him.” + 

Whyland shot a quick glance at Mr. Ludgrove. It was from him that he had first learnt of this attachment. Ludgrove nodded almost imperceptibly, and Whyland turned once more to Ted. + 

“There was nothing preying on his mind, was there?” he asked. + 

“Well, I’ve thought sometimes that he fair had the wind up about this black sailor,” replied Ted reluctantly. “I never knew what to make of that. He told me one day that he’d met him coming out of the Cambridge Arms, but I never could quite believe it somehow.” + 

“As it happens, I share your scepticism,” said Whyland. “Mr. Ludgrove here was in the street at the time, and saw your father come out of the Cambridge Arms. There was nobody but himself and your father in sight, he assures me.” + 

“That is so,” assented Mr. Ludgrove gravely. + 

“Well, I’m not surprised,” said Ted. “It’s a funny thing, but these things always happen when he’d been to the Cambridge Arms of an evening. It was when he came home from there that he found that counter the other day?” + 

“Have you ever seen your father definitely under the influence of liquor?” asked Whyland. + 

“Why no, not to say actually squiffy. He’d talk freer than usual, and imagine all sorts of yarns about things that never happened. I think he got the black sailor on his brain sometimes. When he first got the counter he made up his mind that the black sailor was going to get him. But the last day or two he’s been much more cheerful. Of course, it’s possible that this evening, when he was alone, it got on his mind again.” + 

The conversation was interrupted by the return of Waters, the detective. “I’ve searched as best I can for that syringe, sir, and I can’t find it,” he reported. “I’ll have another good look as soon as it gets light, if you like, sir.” + 

“Yes, do,” replied Whyland. “Now, you were supposed to be watching this place all the evening. What time did Mr. Copperdock come in?” + 

“Between nine and ten, sir. Two fellows came with him, and the three stood talking at the door for a minute or two. Then they all went in, and the door was shut behind them. It was close on eleven when it opened again, and the two men came out. Mr. Copperdock came downstairs with them, I saw him just inside the door talking to them. Then they went away, and the door was shut again. A few minutes after they had gone I saw a light come on in this room.” + 

“You can’t see into the room from the opposite pavement, I suppose?” + 

“Only a bit of ceiling, sir. I noticed the window was open at the top, and the curtains not properly drawn, like you see them now, sir. They’ve never been properly drawn since I’ve been watching the house. The next thing that happened was that Mr. Copperdock’s son came along at about a quarter past twelve, and let himself in with a key.” + 

Inspector Whyland turned to Ted. “What time did you go out?” he asked. + 

“About eight o’clock. Dad was just getting ready to go round to the Cambridge Arms.” + 

“Where were you between eight and a quarter past twelve?” + 

“With Miss Tovey,” replied Ted, readily enough, but with an awkward blush. “We went to a dance, then we had some supper. After that I saw her home, and stayed there a few minutes. I walked home from Lisson Grove, found Dad like this, and ran straight across to fetch Mr. Ludgrove.” + 

“Nobody but you and your father had a key to the premises, I suppose?” + 

“No. One of us always came down to let the charwoman in in the morning.” + 

“You are perfectly certain, Waters, that nobody came to the house between eleven and a quarter past twelve?” enquired Whyland. + 

“Certain, sir. I was in the street outside all the time, and never took my eyes off the place.” + 

“Very well. You stay here with the body. I’ll arrange for it to be taken to the mortuary as soon as I can. As for you, young man, you had better go to bed and try to get some sleep. We shall want you in the morning. Mr. Ludgrove, if you’ve nothing better to do, I should like you to come round the house with me. I want to make certain that nobody can have broken in.” + 

Mr. Ludgrove nodded, and the two left the room together. Whyland examined the sitting-room window. It was shut and fastened, and bore no traces of violence. Then they went downstairs and looked over the ground floor, without discovering anything in any way out of the ordinary. + 

When they reached the office behind the shop, Whyland closed the door and sank wearily into a chair. “Well, Mr. Ludgrove, what do you make of it?” he said. + 

“I couldn’t help overhearing snatches of your conversation with the doctor,” replied the herbalist. “I confess that I cannot understand why, if Mr. Copperdock wished to poison himself with a hypodermic injection, he should select his back for the purpose, unless he had some confused idea of a lumbar puncture. Yet, on the other hand, he is not likely to have let someone else drive a needle into him without a struggle, and of that there is no trace, so far as I could see.” + 

“And how did that person get in?” put in Whyland quickly. “That is, if both Waters and young Ted are telling the truth. Waters is a good man, and I haven’t the least reason to suspect him. But it’s just possible that he was dozing somewhere between eleven and twelve, and that Ted came home before he said he did. His father wouldn’t be surprised to see him, and he might have walked up behind him and jabbed the needle in. Then, when his father found out what he’d done, he got a bit of caustic potash from somewhere and clapped it on. I know there are lots of difficulties, but at least it’s possible. At all events, I can’t think of another alternative to the suicide theory.” + 

“The case is extraordinarily puzzling,” said Mr. Ludgrove sympathetically. “If you feel disposed to discuss it, Inspector, I suggest that you do so in comfort over at my place. I can make you a cup of cocoa, or, if you prefer it, I can supply you with something stronger. I always kept a bottle of whiskey in reserve for poor Mr. Copperdock.” + 

“Well, it’s very good of you, Mr. Ludgrove,” replied Whyland gratefully. “What’s the time? After two? I want to stay about here until it’s light. I’ll just tell Waters where I’m to be found in case he wants me. Then I shall be very glad to accept your kind hospitality.” + 

He left the room and returned after an absence of a couple of minutes. “I can’t make it out,” he said. “Waters swears he never had his eyes off the place. Still, it won’t do any harm to make enquiries into young Ted’s movements and verify his statement. It beats me, but then everything Copperdock did was a puzzle. His name seemed to crop up in connection with each of these deaths, somehow. Then there was that yarn about the black sailor, the counter which he said he found on his bed, and now his amazing death. Well, I’m ready to go across if you are, Mr. Ludgrove.” + 

The two passed through the shop into the road. As they crossed it, Mr. Ludgrove uttered an exclamation of surprise. “Why, the door of my shop is open!” he said. “I must have forgotten to shut it in my haste when Ted Copperdock came over for me.” + 

“Let’s hope no inquisitive visitor has been in to have a look round while we’ve been over the way,” replied Whyland. + 

Mr. Ludgrove smiled. “He will have found very little of value to reward him if he has,” he said. “No, I’m not afraid of burglars. In any case, it’s a very old-fashioned lock which anyone could force without any difficulty.” + 

They had reached the door by now, and Mr. Ludgrove pushed it open. “Come along, Inspector, we’ll go into the back room,” he said, leading the way. + 

At the door of the inner room he paused, and switched on the light. At a first glance, the room appeared to be exactly as he had left it to answer Ted’s urgent summons. Then suddenly he clutched Whyland’s arm, and pointed straight in front of him with a shaking finger. + 

On the mantelpiece, propped conspicuously against the clock so that it could not fail to attract attention, was a white bone counter, upon which the figure VII had been carefully traced. + 
