One day in the spring of ‘93, soon after Miss Williams’ trunks, containing her theatrical costumes, had been brought to our rooms in the block in Chicago, returning from the city one afternoon, I met upon the stairway leading to my office a jauntily dressed young man, whom, as I passed, I asked to cease smoking his cigarette within the building, and a few minutes later was being saucily laughed at in my office by Miss Williams. So clever had the deception been, both in clothing and change in facial expression by aid of her color box, that upon her wishing to do so, I allowed her to accompany me upon a trip to Aurora, Ill., and later to St. Joseph, Mich., costumed in this manner. That both of these trips, made under these circumstances, actually occurred, I am able to prove by competent and disinterested persons, and I feel sure that Miss Williams was in Toronto, probably meeting the children at Hamilton, and returning with them, and keeping one with her while the other was killed; and next day, while I must necessarily have been hundreds of miles away, inasmuch as I registered at Prescott at 4 P. M., she, if any one, met Hatch near this house, disguised in this manner. On August 15th, Mr. Cops, a Fort Worth attorney, obtained permission of the District Attorney to interview me, and, after questioning me for a time, said he would like to tell me his theory of how I had killed my Chicago victims, which was that while they were in my office I had in some way induced them to step inside the vault and then caused their death by suffocation. He said, “Why, Holmes, it is the plainest case I ever heard of, even the footprints of one of them are to be seen upon the door, where in their desperation they had tried to make their escape.” I asked him when he believed the last of these deaths had occurred there. He replied, “Probably in July, 1893. In fact, if you could show me that Minnie Williams was alive after that date, I would be much inclined to believe that she was alive now and that she killed her sister, as you say, for, if alive, only that could have been a sufficient motive to induce her to conceal her whereabouts for so long from her Texas friends.” I said, “Will you grant me that I am not guilty of taking life there since I left Chicago about January 1, 1894, for Texas.” He replied, “Yes, I think that would be safe from the evidence I have gathered in Chicago.” I said, “In August, 1893, a fire occurred in the building, causing the destruction of many valuable letters and papers, and upon the building being repaired I bought this vault, in October or November, 1893, from a safe and vault company whose offices were one block west of La Salle street, between Madison and Adams, in Chicago. The purchase was made in the name of the Campbell-Yates Company, and in December, 1893, it was put in place and plastered by a workman named Kriss.
