very glad to know you," said Forrester. "Now, may I inquire how you happened to call on me?"
"Sure thing," returned Humphrey. "You see, our police reporter informed us that you had been to the detective bureau today – that you had received one of those notices from the 'Friends of the Poor.' Owing to the death of a prominent man like Mr. Nevins, which is attributed to these people, our paper is going to run a special feature article tomorrow morning, reviewing the whole history of this affair. Naturally, we want to know all the details of each case, and what every one connected with it has to say. As you seem to be the latest victim, we are interested in the particulars of your case, and your personal views regarding it."
"I am afraid," declared Forrester, "that the details of one case correspond very closely to those of any other case. I have merely received a warning to put ten thousand dollars in a certain tree by midnight Saturday or take the consequences."
"You're quite right," agreed Humphrey. "The method in each case is the same. But the outcome is not always the same. What do you propose doing in the matter?"
"Well, for one thing," asserted Forrester, "I do not intend to pay!"
"That's the stuff!" approved Humphrey. "If everyone would fight, we'd soon put those fellows out of business. But," he added, leaning confidentially toward Forrester, "how do you propose to fight them?"
"That," said Forrester, "is a question I have not entirely settled as yet. As you know, I went to the detective bureau this afternoon."
"Poof!" grunted Humphrey, leaning back and flicking the ashes from his cigar.
"And I have also engaged a private detective," added Forrester.
"Who?" queried Humphrey.
"A man named Green – Benjamin F. Green."
"There are detectives – and there are detectives," commented Humphrey. "Green falls in the first class."
"I think I get your meaning," smiled Forrester, "and I am inclined to agree with you. That, in fact, is the great problem which confronts me now – how to get a good detective at work on the case. Any suggestions, Mr. Humphrey?"
"I'm a better knocker than I am a suggester," explained Humphrey. "I can tell you the faults of detectives as easily as I could run over my A-B-Cs. I'll admit, though, that there are some good ones. Sooner or later one of them will get on this case and solve it. I wouldn't care to take the responsibility of recommending anyone."
"I know you came here for an interview, Mr. Humphrey," said Forrester, "and I realize how dangerous it is to tell all your plans to a man who is seeking news. But on the other hand, I have a very high opinion of the ability and cleverness of newspaper men. That is why I am going to take you into my confidence."
"I'm enjoying it," assured Humphrey, selecting and lighting another cigar.
"The fact is," announced Forrester, "I am thinking of becoming a detective in this matter myself. The question is, can I do it – have I the ability to be a detective?"
"Why not?" queried Humphrey.
"Well, what, in your opinion, makes a good detective?"
"Brains!" shot back Humphrey. "Look here, Mr. Forrester. As a reporter I can scent the biggest story ever scooped up by a Chicago newspaper. A rich man, in the face of dangerous threats, turning detective and running down a criminal band which has defied the best efforts of the police department. All I ask is that you give me the dope first!"
"Then I may count on you to keep my plans quiet and give me a certain amount of assistance?" questioned Forrester.
"You bet!" exclaimed Humphrey. "To tell you the truth, you've actually got me going. I can see real possibilities to the idea. Now, look here, Mr Forrester; my paper assigned the 'Friends of the Poor' story to me the first time the matter came up. They have kept me at it since because I was familiar with the details. I don't pretend to have any detective instincts, but just my share of common sense, and I have thought the whole matter over pretty carefully. The police, of course, would laugh at any theories from me, but you, perhaps, might like to hear my ideas on the subject."
"Go ahead," urged Forrester.
"In my opinion," Humphrey explained, "the police have fallen down so far on this case because they are sticking too close to the rules. The average city detective becomes familiar with the ways of the average thug-type of criminal. Give him an ordinary murder, burglary, or blackmailing case and he knows just about where to go to get his hands on the people he wants. But when a different class of criminal begins to operate, the average detective cannot see the new conditions. He goes floundering along the same old lines and lets real clues slip through his fingers."
Humphrey paused to relight his cigar.
"Go on," again urged Forrester. "I am learning something."
"Now," continued Humphrey, "the crooks that compose the 'Friends of the Poor' have been operating for about one year. In that time they have received various sums running from ten thousand to twenty-five thousand dollars. I venture to say that in one year's time they have taken in pretty close to two hundred thousand dollars! Now, I ask you, Mr. Forrester; if you were taking in that amount of money, where would you have your hangout? In some West Side saloon or tenement, or in a high class neighborhood – perhaps even in some fine hotel? Do you get my thought, Mr. Forrester?"
"I think I do," said Forrester.
"All right, then," went on Humphrey. "I happen to know what the police are doing in this matter. They are dividing their time between watching an old oak up on the North Shore, and rummaging around West Side dives. Somewhere, in between, our men sit laughing at them!"
"I am strongly inclined to believe you are right, Mr. Humphrey," assented Forrester. "But the important question is: How are we going to locate that place which lies in between?"
"That's where you come in," maintained Humphrey. "That's where your money, social position, training and brains are going to enable you to give the ordinary detectives the go-by. When you mentioned becoming a detective, an idea hit me with an awful wallop. Now, Mr. Forrester, you're an engineer."
"How did you know that?" queried Forrester.
"We usually look up a man before we interview him. We know all about you."
"I see," smiled Forrester. "Well, then, as an engineer how am I going to solve this problem in crime?"
"By triangulation!" exclaimed Humphrey.
Forrester laughed. "Now you have got me guessing, Mr. Humphrey. As a civil engineer I have used triangulation in my surveying work on many occasions, but how I can apply it to a criminal problem is beyond me."
"Well," explained Humphrey, "the first thing to do in a criminal case is to take a good survey of the problem and the ground it covers – just as you do when you build a bridge, a dam, or open up a mine. The higher type of criminal investigator usually falls back upon his study and knowledge of criminology, which is a broader and more scientific development of the ordinary facts with which the city detective starts to work. What I am going to suggest to you is a new branch of criminology. For want of a better name at this time we'll call it Engineering-Criminology. I am not an engineer myself, and what I know about surveying and triangulation could be put into a thimble, but I think I know enough to give you an idea of what I mean.
"As I said before, the detectives are wallowing around in the mire of the lower West Side – they are in the valley, so to speak. Now, if you, as an engineer, were about to survey a certain unknown and inaccessible territory, you'd go up on the nearest high hill and pick out two other prominent points in the landscape, so as to form a triangle. Then you'd take sights, or whatever you would call it, from one point to another. A little figuring would give you the exact distance from one point to another, and a lot of information about the lay of the land in between. Am I not right?"
"You've put it very roughly, but I think I can see what you are driving at," returned Forrester.
"Continue the idea a little further, Mr. Forrester," went on Humphrey. "If you were making a mine survey you would first lay out your boundaries,
