The little piece which follows this preface accordingly takes the form of a farcical comedy, because it is a contribution to the very extensive dramatic literature which takes as its special department the gallantries of married people. The stage has been preoccupied by such affairs for centuries, not only in the jesting vein of Restoration Comedy and Palais Royal farce, but in the more tragically turned adulteries of the Parisian school which dominated the stage until Ibsen put them out of countenance and relegated them to their proper place as articles of commerce. Their continued vogue in that department maintains the tradition that adultery is the dramatic subject par excellence, and indeed that a play that is not about adultery is not a play at all. I was considered a heresiarch of the most extravagant kind when I expressed my opinion, at the outset of my career as a playwright, that adultery is the dullest of themes on the stage, and that from Francesca and Paolo down to the latest guilty couple of the school of Dumas fils, the romantic adulterers have all been intolerable bores. + 
