At this time female detectives were unheard of. I told her it was not the custom to employ women as detectives, but asked her what she thought she could do.

She replied that she could go and worm out secrets in many places to which it was impossible for male detectives to gain access. She had evidently given the matter much study, and gave many excellent reasons why she could be of service.

I finally became convinced that it would be a good idea to employ her. True, it was the first experiment of the sort that had ever been tried; but we live in a progressive age, and in a progressive country. I therefore determined at least to try it, feeling that Mrs. Warne was a splendid subject with whom to begin.

I told her to call the next day, and I would consider the matter, and inform her of my decision. The more I thought of it, the more convinced I became that the idea was a good one, and I determined to employ her. At the time appointed she called. I entered into an agreement with her, and soon after gave a case into her charge. She succeeded far beyond my utmost expectations, and I soon found her an invaluable acquisition to my force.

The Vice-President placed such full reliance in me that I had no hesitation in giving him the above sketch of Kate Warne, and advising that she be sent to Jenkintown, accompanied by a young lady who should have no direct connection with the case, but simply act as Kate's companion and friend. I knew this would greatly increase the expenses, but, as he well knew, we were now dealing with an uncommonly smart man and woman, and in order to succeed, we must be sharp indeed!

As I had previously said, when a person has a secret, he must find some one in whom to confide, and talk the subject over with him. In this case Maroney had evidently confided the secret of the robbery to his wife, and now, while they were apart, was the time to draw it out. What was wanted was a person who could ingratiate herself into the confidence of Mrs. Maroney, become her bosom friend, and so, eventually, be sure of learning the secret of her overwrought mind, by becoming her special confidante.

I also suggested the propriety of placing a handsome, gentlemanly man at Jenkintown, who should be provided with a span of horses and a handsome carriage, and deport himself generally as a gentleman of leisure. His duties would be to get up a flirtation with Mrs. Maroney, prevail on her to drive out with him, and, if possible, entice her to quiet, little fish-suppers, where he could ply her with champagne, and, under its exhilarating influence, draw from her portions of her secret. A woman of Mrs. Maroney's stamp, while separated from her husband, would most likely desire gentlemen's company, and as she, like most of her class, would put up with none but the handsomest, it was necessary to select as fine a looking man to be her wooer as could be found. She seemed to have already provided herself with a lover, in the person of Hastenbrook, and it was necessary to get some one able to "cut him out."

The company had a gentleman in their employ, named De Forest, whom I thought admirably adapted for this purpose, and if the Vice-President would allow me, I would assign to him the task of becoming Mrs. Maroney's lover. The instructions I would give him would be few and simple, and he need know nothing of the case, further than that he was to go to Jenkintown with a carriage and span of horses, make himself acquainted with Mrs. Maroney, and report daily all that took place.

I had already given Mr. Bangs entire charge of the detectives employed in the case, so that he would remain in Philadelphia, while I would keep up a constant communication with him by telegraph and mail.

The Vice-President coincided with me in all my plans, and said the Adams Express were going to let me have my own way, and that they had unbounded confidence in me. I felt that their placing such entire confidence in a young man like me was indeed flattering, and I was determined to prove to them that their confidence was not misplaced. Having made all necessary arrangements in Philadelphia, I left for Chicago to prepare Mrs. Warne and her friend for the case.
