With regard to the moral influence of their duties, I say boldly that it is in no respect different from that of any other position where women are thrown upon their own resources. It is an unfortunate fact in our social system, that no single woman or widow, dependent upon herself for support, can escape a loss of caste and position by working in the great field of business where she comes in competition and contact with men; but, aside from this general prejudice, there is nothing in the detective's duties to make her profession less respectable and honorable than there is in the duties of a lady cashier, book-keeper, copyist, or clerk. The detective's temptations are no greater than those of any of the foregoing who mingle with men in their daily business; while, on the other hand, the safeguards of their virtue are much more numerous, since all the detectives of my agency know that their conduct is under constant surveillance.

There are instances of frequent occurrence where great criminals are successful in hiding all traces of their guilt so effectually as to make their conviction impossible without the aid of the female detective. Most of these men have wives or mistresses in whom they confide to a great extent. The testimony of these women, then, become the sole means by which to convict the criminals, and their testimony can be obtained in only one way—a female detective makes their acquaintance, wins their confidence, and draws out the story of the crime. Such an instance is given in "The Expressman and the Detective," hitherto published.

I have in my employ several ladies of unquestionable purity of life, who are also among the most successful operators on my whole force. I take pleasure in offering this tribute to their ability, and their spotless characters.

The next day the Captain called to see me, and said that, according to my advice, he had quarreled with Annie about Pattmore, and had worked himself into a great rage. Finally, he had torn up and burned his will, saying that he should immediately make another, leaving everything to Lucy.

"So far, so good," said I; "she now will have no motive for poisoning you, so you can rest in peace."

The Captain stated further that he had deposited in bank a few hundred dollars which he had brought with him, so that he felt comparatively safe for the present.

That evening Miss Seaton reported that Mrs. Thayer had left the house shortly after the Captain. Miss Seaton had followed her to the post-office, where Mrs. Thayer had deposited a letter, and had received another at the ladies' window. She had immediately torn it open, read it hastily, and crumpled it in her hand, while slowly walking home. I was very anxious to know to whom she had written, and also who had written to her. I immediately wrote to Miller to watch Pattmore's mail, and to learn whether there were any letters in it from Chicago. If so, I wished him to obtain a view of the handwriting, and, if possible, to get possession of the letters themselves long enough to take copies of them.

The next morning Captain Sumner came in again, but he had nothing to report.

"Does Annie write much?" I asked.
