One afternoon he came to me with quivering sides, and told me that an idea for a little shilling book had occurred to him. It was that a Radical Prime Minister and a Conservative working man should change into each other by supernatural means, and the working man be confronted with the problem of governing, while the Prime Minister should be as comically out of place in the East End environment. He thought it would make a funny 'Arabian Nights' sort of burlesque. And so it would have done; but, unfortunately, I saw subtler possibilities of political satire in it, nothing less than a _reductio ad absurdum_ of the whole system of Party Government. I insisted the story must be real, not supernatural, the Prime Minister must be a Tory, weary of office, and it must be an ultra-Radical atheistic artisan bearing a marvellous resemblance to him who directs (and with complete success) the Conservative Administration. To add to the mischief, owing to my collaborator's evenings being largely taken up by other work, seven-eighths of the book came to be written by me, though the leading ideas were, of course, threshed out and the whole revised in common, and thus it became a vent-hole for all the ferment of a youth of twenty-one, whose literary faculty had furthermore been pent up for years by the potential censorship of a committee. The book, instead of being a shilling skit, grew to a ten-and-sixpenny (for that was the unfortunate price of publication) political treatise of over sixty long chapters and 500 closely printed pages. I drew all the characters as seriously and complexly as if the fundamental conception were a matter of history; the outgoing Premier became an elaborate study of a nineteenth-century Hamlet; the Bethnal Green life amid which he came to live was presented with photographic fulness and my old trick of realism; the governmental manoeuvres were described with infinite detail; numerous real personages were introduced under nominal disguises; and subsequent history was curiously anticipated in some of the Female Franchise and Home Rule episodes. Worst of all, so super-subtle was the satire, that it was never actually stated straight out that the Premier had changed places with the Radical working man, so that the door might be left open for satirically suggested alternative explanations of the metamorphosis in their characters; and as, moreover, the two men re-assumed their original _rôles_ for one night only with infinitely complex effects, many readers, otherwise unimpeachable, reached the end without any suspicion of the actual plot--and yet (on their own confession) enjoyed the book!
