work with, not against, the regular detectives. They’re all right. They’re indispensable, of course. Half the secret of success nowadays is organisation. 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 organisation 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?”
Indeed I did. A wealthy banker of the town had been murdered on the road to the golf club, no one knew why or by whom. Every clue had proved fruitless, and the list of suspects was itself so long and so impossible as to seem most discouraging.
“He sent me a piece of a torn handkerchief with a deep blood-stain on it,” pursued Kennedy. “He said it clearly didn’t belong to the murdered man, that it indicated that the murderer had himself been wounded in the tussle, but as yet it had proved utterly valueless as a clue. Would I see what I could make of it?
“After his man had told me the story I had a feeling that the murder was committed by either a Sicilian labourer on the links or a negro waiter at the club. Well, to make a short story shorter, I decided to test the blood-stain. Probably you didn’t know it, but the Carnegie Institution has just published a minute, careful, and dry study of the blood of human beings and of animals.
“In fact, they have been able to reclassify the whole animal kingdom on this basis, and have made some most surprising additions to our knowledge of evolution. Now I don’t propose to bore you with the details of the tests, but one of the things they showed was that the blood of a certain branch of the human race gives a reaction much like the blood of a certain group of monkeys, the chimpanzees, while the blood of another branch gives a reaction like that of the gorilla. Of course there’s lots more to it, but this is all that need concern us now.
“I tried the tests. The blood on the handkerchief conformed strictly to the latter test. Now the gorilla was, of course, out of the question—this was no Rue Morgue murder. Therefore it was the negro waiter.”
“But,” I interrupted, “the negro offered a perfect alibi at the start, and—”
“No buts, Walter. Here’s a telegram I received at dinner: ‘Congratulations. Confronted Jackson your evidence as wired. Confessed.’”
“Well, Craig, I take off my hat to you,” I exclaimed. “Next you’ll be solving this Kerr Parker case for sure.”
“I would take a hand in it if they’d let me,” said he simply.
That night, without saying anything, I sauntered down to the imposing new police building amid the squalor of Center Street. They were very busy at headquarters, but, having once had that assignment for the Star, I had no trouble in getting in. Inspector Barney O’Connor of the Central Office carefully shifted a cigar from corner to corner of his mouth as I poured forth my suggestion to him.
“Well, Jameson,” he said at length, “do you think this professor fellow is the goods?”
I didn’t mince matters in my opinion of Kennedy. I told him of the Price case and showed him a copy of the telegram. That settled it.
“Can you bring him down here tonight?” he asked quickly.
I reached for the telephone, found Craig in his laboratory finally, and in less than an hour he was in the office.
“This is a most bating case, Professor Kennedy, this case of Kerr Parker,” said the inspector, launching at once into his subject. “Here is a broker heavily interested in Mexican rubber. It looks like a good thing—plantations right in the same territory as those of the Rubber Trust. Now in addition to that he is branching out into coastwise steamship lines; another man associated with him is heavily engaged in a railway scheme from the United States down into Mexico. Altogether the steamships and railroads are tapping rubber, oil, copper, and I don’t know what other regions. Here in New York they have been pyramiding stocks, borrowing money from two trust companies which they control. It’s a lovely scheme—you’ve read about it, I suppose. Also you’ve read that it comes into competition with a certain group of capitalists whom we will call ‘the System.’
“Well, this depression in the market comes along. At once rumours are spread about the weakness of the trust companies; runs start on both of them. The System,—you know them—make a great show of supporting the market. Yet the runs continue. God knows whether they will spread or the trust companies stand up under it tomorrow after what happened today. It was a good thing the market was closed when it happened.
“Kerr Parker was surrounded by a group of people who were in his schemes with him. They are holding a council of war in the directors’ room. Suddenly Parker rises, staggers toward the window, falls, and is dead before a doctor can get to him. Every effort is made to keep the thing quiet. It is given out that he committed suicide. The papers don’t seem to accept the suicide theory, however. Neither do we. The coroner, who is working with us, has kept his mouth shut so far, and will say nothing till the inquest. For, Professor Kennedy, my first man on the spot found that—Kerr Parker—was—murdered.
“Now here comes the amazing part of the story. The doors to the offices on both sides were open at the time. There were lots of people in each office. There was the usual click of typewriters, and the buzz of the ticker, and the hum of conversation. We have any number of witnesses of the whole affair, but as far as any of them knows no shot was fired, no smoke was seen, no noise was heard, nor was any weapon found. Yet here on my desk is a thirty-two-calibre bullet. The coroner’s physician probed it out of Parker’s neck this afternoon and turned it over to us.”
Kennedy reached for the bullet, and turned it thoughtfully in his fingers for a moment. One side of it had apparently struck a bone in the neck of the murdered man, and was flattened. The other side was still perfectly smooth. With his inevitable magnifying-glass he scrutinised the bullet on every side. I watched his face anxiously, and I could see that he was very intent and very excited.
“Extraordinary, most extraordinary,” he said to himself as he turned it over and over. “Where did you say this bullet struck?”
“In the fleshy part of the neck, quite a little back of and below his ear and just above his collar. There wasn’t much bleeding. I think it must have struck the base of his brain.”
“It didn’t strike his collar or hair?”
“No,” replied the inspector.
“Inspector, I think we shall be able to put our hands on the murderer—I think we can get a conviction, sir, on the evidence that I shall get from this bullet in my laboratory.”
“That’s pretty much like a story-book,” drawled the inspector incredulously, shaking his head.
“Perhaps,” smiled Kennedy. “But there will still be plenty of work for the police to do, too. I’ve only got a clue to the murderer. It will take the whole organisation to follow it up, believe me. Now, Inspector, can you spare the time to go down to Parker’s office and take me over the ground? No doubt we can develop something else there.”
“Sure,” answered O’Connor, and within five minutes we were hurrying down town in one of the department automobiles.
