"You perhaps are not acquainted with the fact, but the markings of the veins in the back of the hand are peculiar to each individual—as infallible, indestructible, and ineffaceable as finger prints or the shape of the ear. It is a system invented and developed by Professor Tamassia of the University of Padua, Italy. A superficial observer would say that all vein patterns were essentially similar, and many have said so, but Tamassia has found each to be characteristic and all subject to almost incredible diversities. There are six general classes—in this case before us, two large veins crossed by a few secondary veins forming a V with its base near the wrist.
"Already my suspicions had been aroused. I sketched the arrangement of the veins standing out on that hand. I noted the same thing just now on the hand that manipulated the fake apparatus in the laboratory. Despite the difference in make-up Scott and Prescott are the same.
"The invisible rays of the ultra-violet light may have blinded Mr. Haswell, even to the recognition of his own daughter, but you can rest assured, Prescott, that the very cleverness of your scheme will penetrate the eyes of the blindfolded goddess of justice. Burnham, if you will have the kindness to summon the police, I will take all the responsibility for the arrest of these people."
THE SILENT BULLET
BY ARTHUR B. REEVE
"Detectives in fiction nearly always make a great mistake," said Kennedy one evening after a conversation on crime and science. "They almost invariably antagonize the regular detective force. Now in real life that's impossible—it's fatal."
"Yes," I agreed, looking up from reading an account of the failure of a large Wall Street brokerage house, Kerr Parker & Co., and the peculiar suicide of Kerr Parker. "Yes, it's impossible, just as it is impossible for the regular detectives to antagonize the newspapers. Scotland Yard found that out in the Crippen case."
"My idea of the thing, Jameson," continued Kennedy, "is that the professor of criminal science ought to work with, not against, the regular detectives. They're all right. They're indispensable, of course. Half the secret of success nowadays is organization. The professor of criminal science should be merely what the professor in a technical school often is—a sort of consulting engineer. For instance, I believe that organization plus science would go far toward clearing up that Wall Street case I see you are reading."
I expressed some doubt as to whether the regular police were enlightened enough to take that view of it.
"Some of them are," he replied. "Yesterday the chief of Police in a Western city sent a man East to see me about the Price murder—you know the case?"
