"In my hand? Oh, just a private note I got in the same mail."

"Just look at it before you go," I suggested.

Harcout stopped in the door, examined the letter, pulled another from the inside of the envelope, and blurted out sheepishly: "Ah, bless my soul!—Pinkerton, this is just what I wanted. Here, quick, read them both."

I took the letters as Harcout sat down and fanned himself with his glove, and saw that they were dated from Rochester on the previous day. The first one was from Lyon, in which he stated that he had received the enclosed letter in the morning, probably shortly after Fox had strolled out Lake View Avenue, also expressing a desire that Harcout should submit it to me for advice as to the best course to be pursued, and have the reply telegraphed. The enclosed letter was from Le Compte to Lyon, insisting that he should immediately come to his rooms to receive information of the greatest importance. I did not let Harcout know that I had any information concerning Le Compte, but I saw that that portion of Fox's report which stated that he had followed Le Compte to the Arcade the previous evening, where the latter had anxiously inquired for mail, and after that had taken a peep into Lyon's offices, agreed with Lyon's letter as to the time when Le Compte probably expected an answer from him.

I was at loss to know what the dapper little fellow was driving at—whether he and Mrs. Winslow were after further blackmail, or whether he had secured some confession from her while she was lavishing her favors and money upon him, which the treacherous little villain was endeavoring to make bring a good price through Lyon's superstitious faith in the power of those who claimed supernatural powers and a profession of Spiritualism.

I at once decided to go to Rochester and interview this new apparition in the field in company with Lyon, and accordingly told Harcout that I would do so, and would immediately telegraph to Lyon to that effect; upon which he trotted away, announcing his determination to also telegraph, so that Lyon might see that he was "attending closely to our case," as he termed it.

As soon as he had left, I indicted a dispatch to Lyon, asking him to make an appointment with Le Compte for an interview on the next afternoon, when I would be there to accompany him; and after getting my supper, took the evening train and arrived at Rochester the next noon.

After taking dinner at the Waverley, I immediately proceeded to Lyon's offices. He seemed worried and anxious to see me, and felt extremely alarmed about the whole matter, having as yet kept it from his attorney. I had him send a message for him at once, and in a few minutes we were all three in consultation. His attorney, a Mr. Balingal, thought we were doing just right, and, on leaving, privately informed me that in no event should I allow any person that professed mediumistic powers to remain with Lyon alone, as he would be certain to do something which would in some way compromise the case.

A few minutes after Lyon's attorney had left, we took different routes, arriving at the hallway leading to Le Compte's rooms on State street at about the same time, ascending the staircase together. A negro, who had borne a second and a more imperative message to Lyon, was in waiting at the top, and smilingly showed us along the hall in the direction of Number 28, which afterwards proved to be Le Compte's seance-room. The little fellow himself here stepped out of an adjoining room with a very insinuating smile upon his face, which suddenly changed to a look of disappointment as he saw that Mr. Lyon had rather solidly-built company.
