But he was not free from Julia Oliphant and myself, for we knew all about it. His own brother he might fool, had he had one; he might delude the nurse who had rocked him as a child were she still alive; but us he could not deceive. With us his unimaginable alibi would not serve nor his unique anonymity go down. If he wished to know us, he could come up to us (but to us only) with a proffered hand and an ordinary "How do you do." But if he did not wish to know us he had us to fear. We knew his secret.

But nobody else—nobody in the whole round world else.

That, in its essence, and speaking very roughly, was the position; but it is worth examining a little more particularly. I will leave aside for the moment such questions as why we wanted to find him, whether we ought to try to find him, whether, if a man chose to expunge his identity like that he had not a perfect right to do so. I will assume that he was to be sought and found. On that assumption I reasoned as follows:

Here—somewhere—was a man of unknown age and uncertain personal appearance. When last seen he was, and looked, thirty-five, but he may now be, and look, any age up to, or rather down to, sixteen. That depended entirely on the rate of those backward jerks of which he himself had failed to find the ratio. But where begin to look for him? At what Charing Cross or Clapham Junction, where all the world passes sooner or later, wait for him? What tube station watch? Round what street corner lurk? Examine it, I say, a little more closely.

And take first his two scales of time. As a matter of incontrovertible fact he was living in the year 1920. In the year 1920 a big and handsome and athletic man was living a daily life, presumably somewhere in London. But for him that year was 1910, and continually, day by day and hour by hour, he must be struggling to reconcile those two periods. It could make no difference that he knew that he was living in both years simultaneously. A hundred times a day he might say to himself, "I quite understand; this is both 1910 and 1920; I've got them perfectly clear and separate in my head." But the hundred-and-first time would catch him tripping. He would stumble over some sudden and unexpected trifle. Let me make this clear by means of a small incident that happened to myself. Not long ago I walked into Charbonnel's for a cup of tea, and was passing through the shop on the ground floor and about to mount the stairs when I was politely fetched back. I was told, with a smile that might have been given to a man just returned from Auckland or Mesopotamia, that the upper room had been closed for some time. I had not been in Charbonnel's since the early days of the war, and was looking, in 1920, for a Charbonnel's that had ceased to exist.

So Derwent Rose, however much he was on his guard, would once in a while find himself looking for something that no longer existed.

Next, there was the question of money—common money, and how much of it he had got. Obviously, and supposing he was to be found, it was no good looking for him in places where he could not possibly afford to be. He would be found in a cheaper place or a more expensive one according to the state of his purse. I had no means of knowing how much money he had withdrawn from the bank. I had never known much about his finances except that sometimes he had been hard-up, at others comparatively "flush," but that he had never, as far as I knew, borrowed. Thus the vulgarest of all considerations had an important bearing on our very first step: Where to look for him?

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.
