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.
Three or four days after William's arrival in Union City, he was informed by the superintendent of the express company having charge of the operation, that there was a young man in Moscow who could give important information relative to the first robbery at that place. This young man, Thomas Carr by name, was a lawyer who had once had fine prospects, but he had become very dissipated, and he finally had been taken seriously ill, so that he had lost his practice. On recovering his health he had reformed his habits, but he had found great difficulty in winning back clients, and his income was hardly enough to support him. On learning that this impecunious lawyer had valuable information, William strongly suspected that it would amount to little more than a good lie, invented to obtain money from the express company; nevertheless, he sent for the young man and heard his story.
According to Carr, a man named John Witherspoon had visited him about six weeks before, and had asked him whether he would like to get a large sum of money. Carr replied affirmatively, of course, and wished to know how it could be obtained. Witherspoon had said that the express company could be robbed very easily by boarding a train at any water-tank, overpowering the messenger, and making him open the safe. Witherspoon also had said that he and several others had robbed a train at Moscow some weeks before, and that they had got only sixteen hundred dollars, but that they should do better next time. He had asked Carr to go to Cairo and find out when there would be a large shipment of money to the South; then Carr was to take the same train and give a signal to the rest of the party on arriving at the designated spot.
On hearing Carr's story, William sent him back to Moscow with instructions to renew his intimacy with Witherspoon, and to report any news he might learn at once; in case it should prove to be of any value, the company would pay him well for his services. It is hardly necessary to add that Mr. Carr, having failed to get, as he had hoped, a roving commission as detective at the company's expense, was not heard from again, his bonanza of news having run out very quickly on discovering that no money was to be paid in advance.
The next case was a more plausible one, and William began its investigation with the feeling that something might be developed therefrom. It was learned that a former express messenger named Robert Trunnion, who had been discharged several months before, had been hanging around Columbus, Kentucky, ever since. While in conversation with the clerk of a second-class hotel, Trunnion had spoken of the ease with which a few determined men could board an express car, throw a blanket over the messenger's head, and then rob the safe. The clerk said that Trunnion had made the suggestion to him twice, and the second time he had given Trunnion a piece of his mind for making such a proposition. Trunnion had then said he was only fooling, and that he did not mean anything by it. William learned that Trunnion was then engaged in selling trees for a nursery at Clinton, Kentucky, and that he was regarded as a half-cracked, boasting fool, who might be anything bad, if he were influenced by bold, unscrupulous men. William therefore paid a visit to Mr. Trunnion, whom he found to be a very high-toned youth, too fiery-tempered and sensitive to submit to any questioning as to his words or actions. In a very brief space of time, however, his lordly tone came down to a very humble acknowledgment that he had used the language attributed to him; but he protested that he had meant nothing; in short, his confession was not only complete, but exceedingly candid; he admitted that he was a gas-bag and a fool, without discretion enough to keep his tongue from getting him into trouble continually; and, having clearly shown that he was nowhere in the vicinity of either robbery, he asked humbly not to be held responsible for being a born idiot. William was satisfied that the fellow had told the truth, and, after scaring him out of all his high-toned pride, he let him go, with a severe lecture on the danger of talking too much.
On the nineteenth of November, when the identity of the robbers had been fully established, William was called away to Iuka, Mississippi, on information received from Mr. O'Brien, the general superintendent of the express company, that a man named Santon had seen the leader of the party in that place, just a week before. Santon represented that he knew the man well, having been acquainted with him for years in Cairo, and that he could not be mistaken, as he had spoken with him on the day mentioned. William found that the man Santon was a natural liar, who could not tell the truth even when it was for his interest to do so. The descriptions of the various robbers had been scattered broadcast everywhere, and none of them were represented as over thirty-five years of age; yet Santon said that his man was over fifty years old, and that he had been a pilot on the Mississippi for years. This was a case—not an infrequent one, either—where people talk and lie about a crime for the sole purpose of getting a little temporary notoriety.
