in a moment, a wildly speculative hypothesis had assumed a high degree of probability.

      "When Mr. Stephen was gone, Jervis and I looked over the chambers thoroughly; and then another curious fact came to light. On the wall were a number of fine Japanese colour-prints, all of which showed recent damp-spots. Now, apart from the consideration that Jeffrey, who had been at the trouble and expense of collecting these valuable prints, would hardly have allowed them to rot on his walls, there arose the question: How came they to be damp? There was a gas stove in the room, and a gas stove has at least the virtue of preserving a dry atmosphere. It was winter weather, when the stove would naturally be pretty constantly alight. How came the walls to be so damp? The answer seemed to be that the stove had not been constantly alight, but had been lighted only occasionally. This suggestion was borne out by a further examination of the rooms. In the kitchen there were practically no stores and hardly any arrangements even for simple bachelor cooking; the bedroom offered the same suggestion; the soap in the wash-stand was shrivelled and cracked; there was no cast-off linen, and the shirts in the drawers, though clean, had the peculiar yellowish, faded appearance that linen acquires when long out of use. In short, the rooms had the appearance of not having been lived in at all, but only visited at intervals.

      "Against this view, however, was the statement of the night porter that he had often seen a light in Jeffrey's sitting-room at one o'clock in the morning, with the apparent implication that it was then turned out. Now a light may be left in an empty room, but its extinction implies the presence of some person to extinguish it; unless some automatic device be adopted for putting it out at a given time. Such a device—the alarm movement of a clock, for instance, with a suitable attachment—is a simple enough matter, but my search of the rooms failed to discover anything of the kind. However, when looking over the drawers in the bedroom, I came upon a large box that had held a considerable quantity of hard stearine candles. There were only a few left, but a flat candlestick with numerous wick-ends in its socket accounted for the remainder.

      "These candles seemed to dispose of the difficulty. They were not necessary for ordinary lighting, since gas was laid on in all three rooms. For what purpose, then, were they used, and in such considerable quantities? I subsequently obtained some of the same brand—Price's stearine candles, six to the pound—and experimented with them. Each candle was seven and a quarter inches in length, not counting the cone at the top, and I found that they burned in still air at the rate of a fraction over one inch in an hour. We may say that one of these candles would burn in still air a little over six hours. It would thus be possible for the person who inhabited these rooms to go away at seven o'clock in the evening and leave a light which would burn until past one in the morning and then extinguish itself. This, of course, was only surmise, but it destroyed the significance of the night porter's statement.

      "But, if the person who inhabited these chambers was not Jeffrey, who was he?

      "The answer to that question seemed plain enough. There was only one person who had a strong motive for perpetrating a fraud of this kind, and there was only one person to whom it was possible. If this person was not Jeffrey, he must have been very like Jeffrey; sufficiently like for the body of the one to be mistaken for the body of the other. For the production of Jeffrey's body was an essential part of the plan and must have been contemplated from the first. But the only person who fulfills the conditions is John Blackmore.

      "We have learned from Mr. Stephen that John and Jeffrey, though very different in appearance in later years, were much alike as young men. But when two brothers who are much alike as young men, become unlike in later life, we shall find that the unlikeness is produced by superficial differences and that the essential likeness remains. Thus, in the present case, Jeffrey was clean shaved, had bad eyesight, wore spectacles and stooped as he walked; John wore a beard and moustache, had good eyesight, did not wear spectacles and had a brisk gait and upright carriage. But supposing John to shave off his beard and moustache, to put on spectacles and to stoop in his walk, these conspicuous but superficial differences would vanish and the original likeness reappear.

      "There is another consideration. John had been an actor and was an actor of some experience. Now, any person can, with some care and practice, make up a disguise; the great difficulty is to support that disguise by a suitable manner and voice. But to an experienced actor this difficulty does not exist. To him, personation is easy; and, moreover, an actor is precisely the person to whom the idea of disguise and impersonation would occur.

      "There is a small item bearing on this point, so small as to be hardly worth calling evidence, but just worth noting. In the pocket of the waistcoat taken from the body of Jeffrey I found the stump of a 'Contango' pencil; a pencil that is sold for the use of stock dealers and brokers. Now John was an outside broker and might very probably have used such a pencil, whereas Jeffrey had no connection with the stock markets and there is no reason why he should have possessed a pencil of this kind. But the fact is merely suggestive; it has no evidential value.

      "A more important inference is to be drawn from the collected signatures. I have remarked that the change in the signature occurred abruptly, with one or two alterations of manner, last September, and that there are two distinct forms with no intermediate varieties. This is, in itself, remarkable and suspicious. But a remark made by Mr. Britton furnishes a really valuable piece of evidence on the point we are now considering. He admitted that the character of the signature had undergone a change, but observed that the change did not affect the individual or personal character of the writing. This is very important; for handwriting is, as it were, an extension of the personality of the writer. And just as a man to some extent snares his personality with his near blood-relations in the form of family resemblances, so his handwriting often shows a subtle likeness to that of his near relatives. You must have noticed, as I have, how commonly the handwriting of one brother resembles that of another, and in just this peculiar and subtle way. The inference, then, from Mr. Britton's statement is, that if the signature of the will was forged, it was probably forged by a relative of the deceased. But the only relative in question is his brother John.

      "All the facts, therefore, pointed to John Blackmore as the person who occupied these chambers, and I accordingly adopted that view as a working hypothesis."

      "But this was all pure speculation," objected Mr. Winwood.

      "Not speculation," said Thorndyke. "Hypothesis. It was ordinary inductive reasoning such as we employ in scientific research. I started with the purely tentative hypothesis that the person who signed the will was not Jeffrey Blackmore. I assumed this; and I may say that I did not believe it at the time, but merely adopted it as a proposition that was worth testing. I accordingly tested it, 'Yes?' or 'No?' with each new fact; but as each new fact said 'Yes,' and no fact said definitely 'No,' its probability increased rapidly by a sort of geometrical progression. The probabilities multiplied into one another. It is a perfectly sound method, for one knows that if a hypothesis be true, it will lead one, sooner or later, to a crucial fact by which its truth can be demonstrated.

      "To resume our argument. We have now set up the proposition that John Blackmore was the tenant of New Inn and that he was personating Jeffrey. Let us reason from this and see what it leads to.

      "If the tenant of New Inn was John, then Jeffrey must be elsewhere, since his concealment at the inn was clearly impossible. But he could not have been far away, for he had to be producible at short notice whenever the death of Mrs. Wilson should make the production of his body necessary. But if he was producible, his person must have been in the possession or control of John. He could not have been at large, for that would have involved the danger of his being seen and recognized. He could not have been in any institution or place where he would be in contact with strangers. Then he must be in some sort of confinement. But it is difficult to keep an adult in confinement in an ordinary house. Such a proceeding would involve great risk of discovery and the use of violence which would leave traces on the body, to be observed and commented on at the inquest. What alternative method could be suggested?

      "The most obvious method is that of keeping the prisoner in such a state of debility as would confine him to his bed. But such debility could be produced by only starvation, unsuitable food, or chronic poisoning. Of these alternatives, poisoning is much more exact, more calculable in its effect and more under control. The probabilities, then,
