“Well, then, here was a crucial fact. The mark of a left hand on a left hand proved the presence of a second person, and at once raised a strong presumption of homicide, especially when considered in conjunction with the unaccountable state of the body. During the evening, a visitor had come and gone, and on him--Bilsky--the suspicion naturally fell. But Mrs. Manford unwittingly threw an entirely new light on the case. You remember she told us that her husband had opened a new bottle of hair dye on the very morning before the explosion and had applied it with unusual care. Then his hair was dyed. But the hair of the corpse was not dyed. Therefore the corpse was not the corpse of Manford. Further, the presumption of murder applied now to Manford, and the body almost certainly was that of Bilsky.” “How did you deduce that the hair of the corpse was not dyed?” I asked. “I didn’t deduce it at all. I observed it. You remember a little patch of hair above the right ear, very much singed but still recognizable as hair? Well, in that patch I made out distinctly two or three white hairs. Naturally, when Mrs. Manford spoke of the dye, I recalled those white hairs, for though you may find silver hairs among the gold, you don’t find them among the dyed. So the corpse could not be Manford’s and was presumably that of Bilsky. “But the instant that this presumption was made, a quantity of fresh evidence arose to support it. The destruction of the body was now understandable. Its purpose was to prevent identification. The parts destroyed were the parts that had to be destroyed for that purpose: the face was totally unrecognizable, and the right hand and right foot were burnt and shattered to fragments. But these were Bilsky’s personal marks. His right hand was mutilated and his right foot deformed. And the fact that the false teeth found were undoubtedly Manford’s was conclusive evidence of the intended deception. “Then there were those very queer financial transactions, of which my interpretation was this: Manford borrowed two thousand pounds from Clines. With this he opened an account in the name of Elliott. As Elliott, he lent himself two thousand pounds--with which he repaid Clines--subject to an insurance of his life for that amount, taken out in Elliott’s name.” “Then he would have gained nothing,” I objected. “On the contrary, he would have stood to gain two thousand pounds on proof of his own death. That, I assumed, was his scheme: to murder Bilsky, to arrange for Bilsky’s corpse to personate his own, and then, when the insurance was paid, to abscond--in the company of some woman--with this sum, with the valuables that he had taken from Bilsky, and the five hundred pounds that he had withdrawn from the bank.
