We were standing directly in the light of an eastern window. Deception was impossible, even if I had felt like employing it. In Sinclair's interests, if not in my own, I resolved to be as true to our host as our positions demanded, yet, at the same time, to save Gilbertine as much as possible from premature if not final suspicion. I therefore replied: "That is a question I can answer as well as Sinclair." (Happy was I to save him this cross-examination.) "While he was showing this toy, Mrs. Armstrong came into the room and proposed a stroll, which drew all of the ladies from the room and called for his attendance as well. With no thought of the danger involved, he placed the trinket on a high shelf in the cabinet, and went out with the rest. When he came back for it, it was gone." The usually ruddy aspect of my host's face deepened, and he sat down in the great armchair which did duty before his writing-table. "This is dreadful," was his comment, "entailing I do not know what unfortunate consequences upon this household and on the unhappy girl--" "Girl?" I repeated. He turned upon me with great gravity. "Mr. Worthington, I am sorry to have to admit it, but something strange, something not easily explainable, took place in this house last night. It has only just come to light; otherwise, the doctors' conclusions might have been different. You know there is a detective in the house. The presents are valuable and I thought best to have a man here to look after them." I nodded; I had no breath for speech. "That man tells me," continued Mr. Armstrong, "that just a few minutes previous to the time the whole household was aroused last night, he heard a step in the hall overhead, then the sound of a light foot descending the little staircase in the servants' hall. Being anxious to find out what this person wanted at an hour so late, he lowered the gas, closed his door and listened. The steps went by his door. Satisfied that it was a woman he heard, he pulled open the door again and looked out. A young girl was standing not very far from him in a thin streak of moonlight. She was gazing intently at something in her hand, and that something had a purple gleam to it. He is ready to swear to this. Next moment, frightened by some noise she heard, she fled back and vanished again in the region of the little staircase. It was soon, very soon after this that the shriek came. Now, Mr. Worthington, what am I to do with this knowledge? I have advised this man to hold his peace till I can make inquiries, but where am I to make them? I can not think that Miss Camerden--" The ejaculation which escaped me was involuntary. To hear her name for the second time in this association was more than I could bear. "Did he say it was Miss Camerden?" I hurriedly inquired as he looked at me in some surprise. "How should he know Miss Camerden?"
