Apart from the central mystery of Manderson’s having arisen long before his usual hour to go out and meet his death, there were two minor points of oddity about this affair which, I suppose, must have occurred to thousands of those who have read the accounts in the newspapers: points apparent from the very beginning. The first of these was that, whereas the body was found at a spot not thirty yards from the house, all the people of the house declared that they had heard no cry or other noise in the night. Manderson had not been gagged; the marks on his wrists pointed to a struggle with his assailant; and there had been at least one pistol-shot. (I say at least one, because it is the fact that in murders with firearms, especially if there has been a struggle, the criminal commonly misses his victim at least once.) This odd fact seemed all the more odd to me when I learned that Martin the butler was a bad sleeper, very keen of hearing, and that his bedroom, with the window open, faced almost directly toward the shed by which the body was found.
The second odd little fact that was apparent from the outset was Manderson’s leaving his dental plate by the bedside. It appeared that he had risen and dressed himself fully, down to his necktie and watch and chain, and had gone out of doors without remembering to put in this plate, which he had carried in his mouth every day for years, and which contained all the visible teeth of the upper jaw. It had evidently not been a case of frantic hurry; and even if it had been, he would have been more likely to forget almost anything than this denture. Anyone who wears such a removable plate will agree that the putting it in on rising is a matter of second nature. Speaking as well as eating, to say nothing of appearances, depend upon it.
Neither of these queer details, however, seemed to lead to anything at the moment. They only awakened in me a suspicion of something lurking in the shadows, something that lent more mystery to the already mysterious question how and why and through whom Manderson met his end.
With this much of preamble I come at once to the discovery which, in the first few hours of my investigation, set me upon the path which so much ingenuity had been directed to concealing.
I have already described Manderson’s bedroom, the rigorous simplicity of its furnishing, contrasted so strangely with the multitude of clothes and shoes, and the manner of its communication with Mrs. Manderson’s room. On the upper of the two long shelves on which the shoes were ranged I found, where I had been told I should find them, the pair of patent leather shoes which Manderson had worn on the evening before his death. I had glanced over the row, not with any idea of their giving me a clue, but merely because it happens that I am a judge of shoes, and all these shoes were of the very best workmanship. But my attention was at once caught by a little peculiarity in this particular pair. They were the lightest kind of lace-up dress shoes, very thin in the sole, without toecaps, and beautifully made, like all the rest. These shoes were old and well worn; but being carefully polished, and fitted, as all the shoes were, upon their trees, they looked neat enough. What caught my eye was a slight splitting of the leather in that part of the upper known as the vamp—a splitting at the point where the two laced parts of the shoe rise from the upper. It is at this point that the strain comes when a tight shoe of this sort is forced upon the foot, and it is usually guarded with a strong stitching across the bottom of the opening. In both the shoes I was examining this stitching had parted, and the leather below had given way. The splitting was a tiny affair in each case, not an eighth of an inch long, and the torn edges having come together again on the removal of the strain, there was nothing that a person who was not something of a connoisseur of shoe-leather would have noticed. Even less noticeable, and indeed not to be seen at all unless one were looking for it, was a slight straining of the stitches uniting the upper to the sole. At the toe and on the outer side of each shoe this stitching had been dragged until it was visible on a close inspection of the join.
These indications, of course, could mean only one thing—the shoes had been worn by someone for whom they were too small.
Now it was clear at a
