Staggered as I had been by Thorndyke’s astonishing statements, I could not repress a grin at the inspector’s artless question. But the grin faded rather abruptly as Thorndyke replied in matter-of-fact tones: “A detailed description is, of course, impossible. I can only sketch out the probabilities. But if you should happen to meet with a negro--a tall negro with a bandaged head or a contused wound of the scalp and a swollen leg--you had better keep your eye on him. The leg which is swollen is probably the left.” The inspector was thrilled; and so was I, for that matter. The thing was incredible; but yet I knew that Thorndyke’s amazing deductions were the products of perfectly orthodox scientific methods. Only I could form no sort of guess as to how they had been arrived at. A negro’s blood is no different from any other person’s, and certainly affords no clue to his height or the condition of his legs. I could make nothing of it; and as the dialogue and the inspector’s note-takings brought us to the little town hall in which the inquest was to be held, I dismissed the puzzle until such time as Thorndyke chose to solve it. When we entered the town hall we found everything in readiness for the opening of the proceedings. The jury were already in their places and the coroner was just about to take his seat at the head of the long table. We accordingly slipped on to the two chairs that were found for us by the inspector, and the latter took his place behind the jury and facing us. Near to him Mr. Foxley and Miss Markham were seated, and evidently hailed our arrival with profound relief, each of them smiling us a silent greeting. A professional-looking man sitting next to Thorndyke I assumed to be the medical witness, and a rather good-looking young man who sat apart with a police constable I identified as Robert Fletcher. The evidence of the “common” witnesses who deposed to the general facts, told us nothing that we did not already know, excepting that it was made clear that Fletcher had left his uncle’s house not later than seven o’clock and that thereafter until the following morning his whereabouts were known. The medical witness was cautious, and kept an uneasy eye on Thorndyke. The wound which caused the death of deceased might have been inflicted by himself or by some other person. He had originally given the probable time of death as six or seven o’clock on Wednesday evening. He now admitted--in reply to a question from Thorndyke--that he had not taken the temperature of the body, and that the rigidity and other conditions were not absolutely inconsistent with a considerably later time of death. Death might even have occurred after midnight.
