The Gloved Hand

by Burton Egbert Stevenson

"Certainly;" and, a moment later, with the prints spread out before us, Sylvester was showing me their points of similarity.

Godfrey came forward while he was talking and stood looking over his shoulder.

I had heard of finger-print identification, of course, many times, but had made no study of the subject, and, I confess, the blurred photographs which Sylvester offered for my inspection seemed to me mighty poor evidence upon which to accuse a man of murder. The photographs showed the prints considerably larger than life-size, but this enlargement had also exaggerated the threads of the cloth, so that the prints seemed half-concealed by a heavy mesh. To the naked eye, the lines were almost indistinguishable, but under Sylvester's powerful glass they came out more clearly.

"The thumb," said Sylvester, following the lines first to the right and then to the left with the point of a pencil, "is what we call a double whorl. It consists of fourteen lines, or ridges. With the micrometer," and he raised the lid of a little leather box which stood on the table, took out an instrument of polished steel and applied it to one of the photographs, "we get the angle of these ridges. See how I adjust it," and I watched him, as, with a delicate thumbscrew, he made the needle-like points of the finder coincide with the outside lines of the whorl. "Now here is a photograph from the other robe, also showing the thumb," and he applied the machine carefully to it. "It also is a double whorl of fourteen lines, and you see the angles are the same. And here is the print of the right thumb which your client made for me." He applied the micrometer and drew back that I might see for myself.

"But these photographs are enlarged," I objected.

"That makes no difference. Enlargement does not alter the angles. Here are the other prints."

He compared them one by one, in the same manner. When he had finished, there was no escaping the conviction that they had been made by the same hand—that is, unless one denied the theory of finger-print identification altogether, and that, I knew, would be absurd. As he finished his demonstration, Sylvester glanced over my shoulder with a little deprecating smile, as of a man apologising for doing an unpleasant duty, and I turned to find Swain standing there, his face lined with perplexity.

"You heard?" I asked.

"Yes; and I believe Mr. Sylvester is right. I can't understand it."

"Well," I said, "suppose we go and have some lunch, and then we can talk it over," and thanking Sylvester for his courtesy, I led Swain away. Godfrey fell into step beside us, and for some moments we walked on in silence.
