The police in various cities having been communicated with to no purpose, Mr. Stone finally decided to do a thing the like of which no newspaper proprietor, perhaps, ever undertook before—that is, start on a personal search for McCoy and his associates. With Frank Murray, one of the best detectives in Chicago, and other detectives, he went to Galesburg, where the gang was said to have a sort of headquarters. The party found there none of the men they were after, but they learned that "Thatch" Grady, a notorious criminal with whom "Butch" McCoy was known to be in relations, was in Omaha. So they hurried to Omaha, but only to find that Grady had gone to St. Louis. Then to St. Louis went Mr. Stone and his detectives, hot on the scent, and spent several days in that city searching high and low.
The method of locating a criminal in a great city is as interesting as it is little understood. The first step is to secure from the local police information as to the favorite haunts of criminals of the class under pursuit, paying special regard in the preliminary inquiries to the possibility of love-affairs; for thieves, even more than honest men, are swayed in their lives by the tender passion, and are often brought to justice through the agency of women. With so much of such information in their possession as they could gather, Mr. Stone and his detectives spent their time in likely resorts, picking up acquaintance with frequenters, and, whenever possible, turning the talk adroitly upon the man they were looking for. It is a mistake to suppose that in work like this detectives disguise themselves. False beards and mustaches, goggles and lightning changes of clothing, are never heard of except in the pages of badly informed story-writers. In his experience of over twenty-five years Mr. Murray never wore such a disguise, nor knew of any reputable detective who did. In this expedition the detectives simply assumed the characters and general style of the persons they were thrown with, passing for men of sporting tastes from the East; and, having satisfied the people they met that they meant no harm, they had no difficulty in obtaining such news of McCoy and the others as there was. Unfortunately, this was not much.
After going from one city to another on various clues, hearing of one member of the gang here and another there, and in each instance losing their man, the detectives finally brought up in New Orleans. They had spent five or six weeks of time and a large amount of money, only to find themselves absolutely without a clue as to the whereabouts of the men they were pursuing. They were much discouraged when a telegram from Mr. Pinkerton told them that "Butch" McCoy was back in Galesburg, where they had first sought him. Proceeding thither with all despatch, they traced McCoy into a saloon, and there three of them,—John Smith, representing the Rock Island Railroad; John McGinn, for the Pinkerton Agency; and Frank Murray, working for Mr. Stone,—with drawn revolvers, captured him, in spite of a desperate dash he made to escape.
McCoy's capture was the occasion of much felicitation among the people interested in the matter. Mr. St. John and Mr. Stone were confident that now the whole mystery of the express robbery could be solved and the murderer convicted. But McCoy showed on trial that he had left New Orleans to come North only the night before the murder and had spent the whole of that night on the Illinois Central Railroad. It also appeared that McCoy's associate, Connors, was in jail at the time of the robbery, and that the man "Jeff" was dead. Thus the whole Plunkett story was exploded.

Some time before this the man who had ridden on the free pass, and given the detectives so much trouble, had been accidentally found by Jack Mullins, a brakeman on conductor Danforth's train. He proved to be an advertising solicitor, employed by no other than Mr. Melville E. Stone, who would have given a thousand dollars to know what his agent knew; for the advertising man had seen the conductor bring out the valise containing the all-important fragment of the draft. But he had not realized the value of the news in his possession, and Mr. Pinkerton took good care to keep him from that knowledge. One hint of the truth to the "Daily News" people, and the whole story would have been blazoned forth in its columns, and the murderer would have taken warning. Not until he had seen the man safely on a train out from Chicago did Mr. Pinkerton breathe easily; and it was not until months later that Mr. Stone learned how near he came to getting a splendid "scoop" on the whole city and country.
The identification of the pass-holder removed the last possibility that the valise had been taken into the train by any of conductor Danforth's passengers. And yet the valise was there! How came it there? In the course of their examination two of the passengers had testified to having seen Schwartz enter the toilet-room during the run. Brakeman Jack Mullins stated that he had been in the same room twice that night, that the second time he had noticed the valise, but that it was not there when he went in first. Other witnesses in the car were positive that the person who entered the room last before the time when Mullins saw the valise was Schwartz. Thus the chain of proof was tightening, and Mr. Pinkerton sent for Schwartz.
After talking with the brakeman in a semi-confidential way for some time, the detective began to question him about Watt, his fellow-trainman. Schwartz said he was a good fellow, and, in general, spoke highly of him. Mr. Pinkerton seemed to hesitate a little, and then said:
"Yes, sir."
