“Motive by itself, however strong, is not enough; and the ferrule evidence is rather slender. It may have been dropped previously.”
“Walter Brooklyn had not been to Liskeard House for more than a week before the murder, and the ferrule was on his stick only three days before.”
“I allow you that point. But, even if his stick was in the garden, it does not follow that he was there. He may have lost it earlier. Prinsep may have had it for all we know. Moreover, what of the evidence which seems to show that Prinsep murdered George Brooklyn? He was seen in the garden just before eleven o’clock. The cigar-holder which he habitually used, and had been using that very evening, was found broken on the spot where the murder was done. Moreover, I have in my possession now a far more decisive piece of evidence. You told me that you were sure the finger-prints on the stone club found in the garden were those of Prinsep. You were perfectly correct. The Finger-Print Department has compared them with the impressions of John Prinsep’s hands, and these coincide beyond a doubt with the marks left on the stone. You have not yet seen the reproductions, inspector. Here they are.”
The superintendent took some papers and photographs from a drawer, and handed them across the table to the inspector, who pored over them for some time without speaking. Finally, he said, with something of a sigh,—
“There can be no doubt they are the same. And, as you say, this throws a quite new light on one of the murders. It seems to prove that George Brooklyn was killed by Prinsep.”
“I do not regard it as proof positive: but it is certainly very strong evidence, especially as the marks on the club are just where a man would take hold in order to deal a smashing blow. The murderer used both hands, you notice. The prints are quite distinct for both the thumbs.”
“Yes, that is clear enough, although none of the impressions is quite complete. Somehow a part of the marks had got rubbed off before the club was properly examined.”
“These accidents will happen. It is only fortunate that the marks were not destroyed beyond hope of identification. Perhaps you yourself, inspector, or one of your subordinates, handled the club carelessly. Or perhaps some one else handled it before you came on the scene.”
“No. I was most careful, and no one touched it after I appeared except myself. The sergeant did not allow it to be touched at all until I arrived. Miss Cowper, who first discovered the body, told me she had not even noticed the weapon, much less handled it. She was too upset to notice anything except the body.”
“Well, I suppose it does not greatly matter, as the identification of the prints is still quite clear. There remains, of course, the bare possibility that, while Prinsep did handle the club, he did not actually kill George Brooklyn. But it is certain that the club was the weapon used. The fragments of hair clotted with blood which are still on it came quite definitely from the head of the deceased. The only doubt in my mind is whether Prinsep was a powerful enough man to strike such a blow. But I suppose we must take it that he was. It was a terrific blow, I understand from the medical evidence.”
