Next there was to be considered a combination of these things--the factor of money-plus-time. Say he had drawn one hundred pounds or five hundred pounds from the bank--for all I knew it might have been either, or more, or less. Well, we all know that a sum that was sufficient for a man in 1910 does not go very far in 1920. There has been a war.... So was he haunting expensive places, having (as might have been said of anybody but him) "a short life and a gay one," or would he be found spinning out his Bradburys as long as possible on a modester scale? Nay, was he even living on his capital at all? Was it not possible that he had found employment of some kind? If so, of what kind? They ask few questions about identity at the dock-gates; was that it, and was he to be looked for in a workman's early-morning tram? Or had he, a man without a shred of paper to be his warranty, managed to talk somebody into something bigger, and was he one of these ephemeral Business Bubbles, lording it for a few months in somebody else's car and floating the higher because of the hotness of the air inside him? I did not think, by the way, that either of these last two things was very likely; but nothing was more impossible than anything else, and I am merely trying to show the size of the haystack in which we must hunt for our needle. The merest glance at the problem made it plain that the only starting point was his last actually-known age--thirty-five. All else was the blindest guesswork. And it was equally plain that the best likelihood of finding him lay in the chance that he would more or less repeat (or seek to repeat) his former experiences at that age. Past associations might pull him, he might frequent some places rather than others, some persons or class of persons rather than others. The question was, could his life at thirty-five be so reconstructed that this hope should not be too slender? That was my idea, and I began to ransack my memory in search of indications that might further it.
