CHAPTER II.
Difficulties.—Blind Trails and False Scents.—A Series of Illustrations showing the Number of Officious People and Confidence Men that often seek Notoriety and Profit through important Detective Operations.
The art of detecting crime cannot be learned in a day, nor can the man of business understand, without previous experience in the habits of criminals, the expedients which the boldest class of law-breakers adopt; hence none but skilled detectives can hope to cope with them. Yet often my clients insist on some certain method of procedure wholly contrary to my judgment and experience, until the total failure of their plan convinces them that there can be but one thoroughly successful mode of detection, namely, to submit the case to a skilled detective of character and standing, and allow him to act according to his judgment.
The range of investigation in such a case as this robbery will often extend from New York to San Francisco, and unless one mind gathers up the clues, classifies the information, and determines the general plan, there will be continual error and delay. Such a state of affairs frequently occurred during this operation, and much time and money were spent upon matters too trifling even for consideration.
The principal of a detective agency, from his long experience with criminals, learns the earmarks of different classes of men, and he is often able to determine the name of the guilty party in any given robbery by the manner in which the job was done. He can readily see whether a novice in crime was engaged, and also whether any collusion existed between the parties robbed and the criminals; and so, when he sees the traces of a bold, skillful, and experienced man, he knows that it is useless to track down some insignificant sneak-thief, simply because the latter happens to have been in the vicinity. Yet, neither will he slight the smallest clue if there is a bare chance that any valuable fact may be obtained from it. But the sine qua non is that he, and he alone, shall direct the whole affair. A divided responsibility simply doubles the criminal's opportunities for escape.
Among the many difficulties of the detective's work, none are more embarrassing than the early development of false clues. In the stories heretofore published, the direct steps leading to the detection and arrest of the criminals have been related, without referring to the innumerable other investigations, which were progressing simultaneously, and which, though involving the expenditure of much thought, time, and money, proved after all to be of no value whatever in developing any evidence in the case. In this operation, such instances were of frequent occurrence, and I propose to mention a few of them to show how wide is the range of the detective's inquiries, and also the annoying delays to which he is often subjected by the inconsiderate zeal and interference of outside parties. These latter may be—indeed, they generally are—well meaning people, anxious to serve the cause of justice; though, on the other hand, they are sometimes spiteful meddlers, striving to fix suspicion upon some personal enemy.
The plan of detection which alone can insure success, must be one which neither forgets nor neglects anything. In investigating any alleged crime, the first questions to be considered are: 1. Has any crime been perpetrated, and, if so, what? 2. What was the object sought thereby?
The matter of time, place, and means employed must then be carefully noted, and finally we come to consider: 1. Who are the criminals? 2. Where are they now? 3. How can they be taken?
The fact that a crime has been committed is generally apparent, though there have been cases in which the determination of that point requires as much skill as the whole remainder of the operation. Such was the case in the detection of Mrs. Pattmore's murder, related in my story of "The Murderer and the Fortune Teller." The object of a crime is also sometimes obscure, and, where such are the circumstances, the detection of the criminal is apt to be one of the most difficult of all operations. Having once solved these two difficulties satisfactorily, however, and having observed the relative bearings of time, place, and means to the crime itself, the question of individuals is the important one to be determined. It often happens that there is no concealment of identity, the problem to be solved being simply the way to catch the guilty parties; but, on the other hand, the greatest skill, experience, patience, and perseverance are sometimes required to discover, first of all, the persons engaged in the crime. Indeed, an operation is often divisible into two distinct methods of action, the first being to find out the identity of the criminals, the second to follow up and capture them.
In the course of a blind trail, such as we were obliged to travel in the case of this express robbery, it was impossible to know whence the men had come or whither they had gone; hence, I was forced to take up every trifling clue and follow it to the end. Even after I was satisfied in my own mind of the identity of the criminals, the agents and officers of the express company were continually finding mares' nests which they wished investigated, and the operation was sometimes greatly hindered on this account. As an example of the number of discouragements which the detective must always expect to encounter, I propose to mention some of the false scents which we were forced to follow during this operation.
