"Is it possible that he has so much influence as that?" I asked.

"Oh, yes," said the Captain; "he is a brilliant speaker, and a very agreeable man socially, so that he makes many friends. He is such a wily scoundrel that I fear we shall have great difficulty in tracing any crime directly to him. I do not care whether he is convicted or not, provided I can rescue Annie from his clutches. He has apparently cast a spell over her, and she is wholly controlled by him."

"If that is the fact, we must use strategy, and undermine his plot with a deeper one. I will accept a retainer from you, Captain, and then we will proceed to work up the case."

The financial part of the arrangement having been adjusted, I gave the Captain some advice as to what he should do. I told him that he must place implicit confidence in me, and not try to interfere in any manner with my plans. If he could not do this, I should withdraw at once. He must come in to see me often and keep me well informed; but he must not expect me to tell him about my plans, any further than I should see fit. I should try to show Pattmore's villainous character to Annie, and if I could gather sufficient evidence that he had poisoned his wife, I should bring him to justice. I then told the Captain that he ought to have a quarrel with Annie, at the end of which he should burn his will in her presence, and leave her; on going out, he should tell her that he intended immediately to deposit his ready money in bank, and make a will wholly in favor of Lucy. This would prevent Annie from again attempting his life, as she would have nothing to gain by his death.

The Captain was satisfied to accept my conditions, and he said that he had full confidence in my ability. All that he desired was to save Annie from the power of Pattmore, and from the ruin which would inevitably result from their further intercourse. He then went home to have his quarrel with his sister.

I determined to send a detective named Miller, to Greenville, to obtain board at the Pattmore House, and, if possible, to become intimate with the proprietor. This part of my plan would require prompt action, as Pattmore might succeed in removing all evidences of his guilt. I therefore, sent for Mr. Miller, and went over all the facts of the case with him, giving him full instructions as to his duties. He was to hail from Bangor, Maine, and to represent that he wished to start in the lumber business in Greenville, if the prospects were good. I told him to post himself thoroughly upon the qualities and prices of all kinds of lumber, lath, shingles, etc., and to read up the local history of Bangor. To make matters easier for him, I gave him a letter of introduction to a lumber dealer in Greenville, with whom I was well acquainted. The next day, Miller was ready, and he took passage to Buffalo by steamer, going thence to Greenville by rail. He then took a room at the Pattmore House, and soon became acquainted with the proprietor.

The same day that I gave Miller his instructions, I sent for Miss Seaton, one of the detectives in the female department, and ordered her to make arrangements to take board in the same house with Captain Sumner and Mrs. Thayer. Miss Seaton was a brunette, about twenty-seven years of age; she was of agreeable appearance and pleasing manners; she had been a school teacher, and was a good judge of human nature. Mrs. Warne, the superintendent of the female department, said that Miss Seaton was very sharp, and that nothing could escape her piercing black eye. She was to cultivate Mrs. Thayer's acquaintance, and endeavor to win her confidence. This would probably be a difficult task; but I told Miss Seaton to be patient and discreet, and not to be discouraged, if she should not be immediately successful. By pretending to be in poor health, she could obtain Mrs. Thayer's sympathy, and their progress toward intimacy would be accelerated. Miss Seaton immediately moved to the City Hotel, whence she set out to look for a boarding place. By a curious coincidence, she could not satisfy herself until she came to the house where Mrs. Thayer was boarding on the North side. There she found a pleasant room adjoining Mrs. Thayer's, and it suited her exactly. That evening at supper, she was introduced to her fellow boarders, of whom there were only three besides the Captain and his sister.

The employment of female detectives has been the subject of some adverse criticism by persons who think that women should not engage in such a dangerous calling. It has been claimed that the work is unwomanly; that it is only performed by abandoned women; and that no respectable woman who becomes a detective can remain virtuous. To these theories, which I regret to say are quite prevalent, I enter a positive denial. My experience of twenty years with lady operatives is worth something, and I have no hesitation in saying that the profession of a detective, for a lady possessing the requisite characteristics, is as useful and honorable employment as can be found in any walk of life.

Previous to the early part of 1855, I had never regularly employed any female detectives; nor were women engaged in that capacity in any part of the Union. My first experience with them was due to Mrs. Kate Warne, an intelligent, brilliant, and accomplished lady. She offered her services to me in the early spring of that year, and, in spite of the novelty of her proposition, I determined to give her a trial. She soon showed such tact, readiness of resource, ability to read character, intuitive perception of motives, and rare discretion, that I created a female department in the agency, and made Mrs. Warne the superintendent thereof.

The work of my female detectives is generally light. Zeal and discretion are the principal requisites, though conscientious devotion to duty, and rigid obedience to orders, are also essential. They are expected to win the confidence of those from whom information is desired, and to lose no opportunity of encouraging them to talk about themselves.
