II
Jupiter is a ball of luminous clouded marble, gigantic in the sky of Ganymede. Its light is a queer, pale glow that lacks the warm brilliance of sunlight. When the titanic planet lifts over the horizon, gravity seems to shift, and the ground feels unstable beneath your feet.
Jupiter was rising now. Oretown lay ugly and desolate in the strange dawn. Across the plain where the spaceship had landed a string of truck-cats, big silvery desert freighters, stood motionless, ready to start the trip. There were signs of activity. At the central port of the Hunter stood a lanky, gray-haired man with a clipped, stiff Van Dyke. Behind him was Captain Brown.
Garth, his medical kit strapped to his back, ploughed through the light film of snow that lay over the sand. He was shivering in his thin garments, wishing he had a drink. Neither Brown nor his companion saw Garth’s approach. The gray-haired man was speaking.
“—time to start. If this guide of yours doesn’t show up, we’ll have to wait till we find another.”
“He’ll show up,” Brown said. “I only gave him ten bucks.”
Garth reached the foot of the ramp leading up to the port-valve. “ ’Morning. Am I late?”
There was no answer. He climbed the slope, slippery with snow despite the skid-treads, and stopped before the two men. Brown nodded at him.
“Here’s our guide, Commander Benson.”
Benson scowled incredulously under tufted brows. “What the devil! You—you’re an Earthman!”
“Sure,” Garth said. “What about it?”
The Commander glanced at Brown. “I expected a native. I didn’t know—” He left the sentence hanging. “You can’t wear those rags, man. Captain, break out some clothes for him.” Without another look at Garth, Benson hurried down the ramp, shouting orders to someone below.
Brown grinned at the other. “Come on inside,” he urged, and, in a lower tone, “He’s the big shot. You know enough to keep your mouth shut—eh?”
Garth nodded. Brown peered at him sharply.
“You need coffee. I’ll lace it. Come along.” He took Garth to the galley, and, presently, supplied food, drink, and clothing. He lit a cigarette, idly watching the smoke sucked into the air-conditioning grill.
“Benson’s a tough egg,” he said at last. “If he had the slightest idea we were figuring on—what we’re figuring on, there’d be trouble. The Commander never takes chances. We’ve got to give him the slip, somehow.”
Garth gulped coffee. “How many men do you have?”
“Ten.”
“Not many.”
“Fully armed, though. There are sixty in the expedition altogether, but I could only feel sure of ten. Some of them I planted myself.”
Garth took the cigarette Brown handed him. “Thanks … I know Chahnn pretty well. Once we get there, we can get away from the others.”
“How?”
“Underground passages—not well known. We’ll come out about thirty miles from Chahnn, and from there it’s another twenty to the Black Forest.”
“The last lap on open ground?”
“Yeah.”
“Not so good. If Benson misses us, he’ll have planes out scouting. I’ve a hunch he’s suspicious already.”
“If he catches up with us, so what? There’ll be other chances.”
“That’s what you think,” Brown said grimly. “I told you Benson was a tough egg. He’d clap us all in the brig and we’d end up with prison sentences on Earth—hazarding the success of a planetary expedition, they call it. So you see why we’ve got to find this treasure, whatever it is.”
“Then you don’t know either, eh?”
“Maybe I’ve a few ideas. … Finished? Let’s go, then.” Brown came to his feet.
Garth followed Brown out of the ship, pondering. The Ancients had, admittedly, been an incredibly advanced race. Any treasure they thought worth guarding would be plenty valuable. Gold? Gems? They seemed trivial, compared to the tremendous scientific powers of the Ancients. And unimportant as well, while the Silver Plague raged over Earth.
They moved along the string of truck-cats, each loaded with the necessary equipment, and reached the first. Commander Benson was already there, talking to the pilot. He looked around.
“Ready? What’s your name—Garth? All right, get in.”
The front compartment of the truck-cat was roomy enough. Paula Trent, Garth saw, was already there. She gave no sign that she noticed him. He shrugged and found a seat, and Captain Brown dropped beside him, impassive as ever.
The pilot came in. “Sit up here, next to me, buddy,” he ordered. “I’ll need your help wrestling this tank through the arroyos.”
Benson himself was the last man to enter. He slid the door shut and nodded.
“Warm her up.”
Beside the driver, Garth could not see the others, nor could he hear their conversation as the motors coughed and snarled into life. The truck-cat lurched forward on her caterpillar treads. The pilot looked inquiringly at Garth.
“Where’ll I head? West? What about these quicksands I’ve been hearing about?”
“Steer for that mountain peak ’way over there,” Garth told him. “It’s easy to see the sinkholes. They’re big grey patches on the sand, with no snow on ’em.”
The roar of the engine died into a monotonous murmur. It was possible to hear the conversation in the rear of the compartment. Commander Benson was talking.
“—atomic power. It must have been that; there’s no other answer. All we need to know is the nature of the booster charge.”
“I don’t get it,” Paula said. “Booster charge?”
“As far as our physicists know, atomic power’s possible if there’s a known way to start it and control it. Earth’s reserves are nearly exhausted. Oil, coal—used up almost completely. And Earth needs power plenty bad, to maintain civilization.”
“The other planets have fuel.”
“Spaceshipping’s too expensive. It’s prohibitive, Paula. Unless a new power source is found very soon, Earthmen may have to migrate to another world—and our civilization’s so complex that that’s nearly impossible. Maybe we can find the answer in Chahnn this time. It was one of the biggest cities of the Ancients.”
“I’ve never seen it,” Captain Brown said.
Benson grunted. “I did, once. Years ago. Tremendous! The scientific achievements they must have had! And nobody knows what happened to the Ancients. They just vanished, and their machines kept running till they’d used up their power—and stopped. So there’s no trace left. We’ve located the fuel chambers, but in every case they’ve been empty. Experiments have been made—unsuccessfully.”
“You still think my translation of the Harro Panel was wrong, eh?” Paula put in.
“I do,” Commander Benson said. “It was a variable cipher. No one else agrees with you that it was a code map.”
“Ever heard of a double code?”
“I’m sorry,” Benson said shortly. “We’ve settled all this. The Black Forest is impassable. We can’t risk our chance of success on a wild goose chase.”
Beside the pilot, Garth’s mouth twisted sardonically. He had an idea, now, what Carver Brown and Paula were after. The secret of the Ancients’ power-source. Well, it might be found in the Black Forest. Anything might. Including the lost race of the Zarno, and. … His eyes went hard. Not yet would he let himself believe Doc Willard was still alive. The most he could hope for was an answer to that question—the tormenting problem of whether or not he had killed Willard.
Lost in his absorption, he snapped out of it scarcely in time as the truck-cat skidded on slick ice.
“Hard left! Sand the treads!” Instinctively his hand flashed to the right lever, releasing a sprinkling of sand that provided traction. He held it down while the pilot fought the wheel. They lurched, swung half around, and found level surface again. Through the window Garth could see a twenty-foot-wide funnel, sloping down to a black hole at the center.
“What was it?” the pilot asked.
“Creethas, the natives call ’em, but that doesn’t mean much. Six-foot insects. Poisonous. They dig traps like antlions on Earth, pits with sloping sides. Once you skid on the ice, you slip on down to the hole at the bottom.”
“Dangerous?”
“Not to us, in here. But we might have damaged the engine.”
“Keep your eyes open after this, Garth,” Commander Benson said sharply.
“Okay.” Garth was silent. The truck-cat drove on, leading the procession.
The vehicles were fast. On level ground they raced, hitting eighty m.p.h. sometimes. By Jupiter-set they had reached Chahnn. Paula, for one, was disappointed.
“I expected a city,” she told Garth as they stared around at the mile-square block of black stone, raised a few feet above ground level, its surface broken by a few structures oddly reminiscent of the subway kiosks of two centuries ago.
“It’s all underground,” Garth said. He was feeling shaky, needing a shot or two of liquor. But there was none. In lieu of it, he borrowed a cigarette from the girl and idled about, watching the men make camp.
The roomy truck-cats provided accommodations for sixty men without crowding. It wasn’t necessary to set up tents. Indeed, in that icy air, only “warmer” tents, heated by induced current in their metallic fabric, would have been feasible. The trucks, however, could be heated easily and were air-conditioned. Garth walked over to a kiosk and peered into the black depths. Chahnn lay below, the gigantic, complicated city of the Ancients.
Through Chahnn was the road to the Black Forest—the only road they could use, under the circumstances.
Garth shivered and went in search of Brown. He was feeling shakier than ever. Vividly in his mind was a picture he did not want to remember—a man stretched on an altar, a knife at his breast. …
He found Brown beside one of the trucks, looking into the darkness.
“Captain—”
“Huh? Oh, Garth. Say, Paula—Miss Trent took a flashlamp and went down into Chahnn to do a bit of exploring. I was thinking of going after her. Any danger down there?”
Garth shook his head. “It’s a dead city. She’ll be okay.”
“Unless she gets lost.”
“She won’t. There are markers pointing to the outlets. How about a drink? I could use one.”
Scowling, Brown nodded and pushed Garth into the truck. “I bunk in here, with the Commander. You’ll have to find a place with the men, somewhere. Oh, by the way—” He pushed folded slips into Garth’s hand. “Here’s the rest of that forty. And here’s a drink.”
Garth gulped brandy better than any he had tasted in years. He didn’t bother with a glass. Brown watched him with an almost imperceptible curl of the lip.
“Thanks. … When do I get that ten thousand?”
“When we’re back here. I don’t trust you quite enough to let you have it now.”
Garth wiped his mouth with the back of his hand, considered, and drank again. “I won’t run out on you. You’re after that Ancients’ power-source, aren’t you?”
Brown’s eyes narrowed a bit. “Any of your business?”
“Not in the way you mean. But I know the Black Forest. I might be able to give you some ideas, if I’m not left too much in the dark. Still, I can guess a little. I know you expect to run into the Zarno.”
“Yeah?”
Garth made an impatient gesture. “Hell, why did you want me as a guide? It wasn’t only because I knew the Forest. I can speak the Ancient Tongue—the same language the Zarno are supposed to use. You’ll want me to palaver with them.”
“Maybe.” Brown went to the back of the truck and found a fresh pack of cigarettes. “We can talk about that later.”
“We ought to talk now. I know what sort of equipment you’ll need in the Forest. If you run out on Benson half-equipped, it’ll be just too bad.”
The door swung open, admitting a blast of frigid air. Commander Benson stepped in, his lips tight and hard, his eyes blazing. Brown, at the end of the chamber, swung around, a sudden, surprised tenseness in his attitude.
“I don’t think you’ll do any running out on me, Captain,” Benson said.
Brown flashed Garth a glance. “Damn you,” he half-whispered. He took a step forward, tigerishly menacing.
Benson pulled a gun from his pocket. “Don’t move,” he said. “Hold it—right there. I thought you’d given up that crazy idea you and Paula had, but apparently—” He shrugged. “Well, I’ll have to put you and the girl under guard. No one in this outfit’s heading for the Black Forest if I can help it.”
Brown’s hand hovered in midair.
“Don’t try it,” Benson said. “Keep your gun where it belongs. The sound of a shot wouldn’t help you any.” He stepped back, his mouth opening in a shout that would summon others.
Brown, at the other end of the truck, could not have reached him in time, but the Commander had forgotten or ignored Garth. That was a mistake. Garth was only a few feet from Benson, and he galvanized into unexpected action. He sprang, one hand clamping over the gun, the other, clenched, driving in a hard, short jab at Benson’s chin.
There was strength in that punch, and it connected at the right point. Had Garth not been gripping the Commander’s hand, the latter would have gone backward, out of the truck.
“Knockout!” Brown said tonelessly. He was suddenly beside Garth, yanking Benson forward. “Shut the door. Quick.”
Garth obeyed. Turning, he saw the Captain kneeling beside Benson’s motionless form. After a moment Brown looked up.
“He’ll come out of it soon. Maybe too soon. Get me those straps from the corner.”
Garth did that, and then had another drink. He felt lousy. He watched Brown bind the Commander and thrust the lax figure out of sight, under a bunk.
“That does it,” Brown said, rising. “We’re in the soup now. But—it was lucky you hit him when you did.”
“What now?”
“We start for the Black Forest before Benson wakes up. I’m second in command. I’ll get my own men, and we’ll jump the gun.” Brown’s eyes were excited.
“Equipment?”
“We’ll take what we can. Weapons, mostly. Stay with me.”
They went out of the truck into the soft light of four moons, two large, two tiny. Fourfold shadows paced them over the icy slick. Garth hurried off to find his medical kit. By the time he returned, Brown had mustered his men and was waiting. He gave Garth a brief glance.
“Okay. Morgan—” He turned to a giant in uniform. “I’ll be back in a couple of hours. As soon as we find Miss Trent. Bye.”
“Bye, sir.”
Garth led the way into one of the kiosks. Lamps were flashed on. A spiral ramp led steeply down.
In an undertone Brown said, “I told Morgan Commander Benson sent me to find Paula Trent—that she was lost in the city. So we’re safe till—”
“We’re safe till we leave the underground passage,” Garth said. “After that, twenty miles across open ground. Has Benson got planes?”
“Portable ones, yeah.”
“Then we’d better do that twenty miles at night.”
The ramp ended. Before them was a gigantic room where their tiny lamps were lost. Here and there enigmatic shadows loomed, the dead, fantastic machines of the Ancients that had once made Chahnn alive and powerful.
Garth went directly to an opening in the wall, Brown and his ten men following, and entered a short tunnel. At one spot he paused, ran his finger over a panel of smooth metal, and pressed. A black oval opened silently.
“Here’s the way. They won’t follow us beyond this point.”
Brown nodded. “Sampson, get the men inside. Wait here for me. I’ll be back as soon as I can.”
A burly, beak-nosed fellow with a cast in one eye and flaming red hair saluted casually. “Right. Come on, boys. Hop through. Mind your packs.”
Garth stared at Brown. “What d’you mean? Where—”
The Captain said, “We’re taking Paula Trent with us.”
“No! It’s nearly suicide for us—she couldn’t make it at all.”
“She’s tougher than you think. Besides, she’s got the map. And she’s an archaeologist. I can’t read the Ancients’ lingo. Can you?”
Garth shook his head. “I can speak it, that’s all. But—”
“If we find what we’re after, we’ll need Paula Trent. She’s down here somewhere. Let’s go find her.”
“I tell you—”
Brown brought out a gun and leveled it.
“Find her. Or I’ll find her myself, and we’ll head for the Black Forest without you. Because you’ll be dead. I haven’t come this far to let you stop me. And chivalry looks a bit funny on a guy like you.”
Sudden murder-light flared in the pale eyes.
“Find her!” Brown whispered. “And—fast!”
