"In the kitchen," repeated the detective. "I at once drew up the blinds, and looked out. The window opened directly on the fire escape, with nothing opposite but the roofs of some low houses. Pulling out my magnifying glass, I crawled out. I soon satisfied myself that the stairs leading up and down had not been recently used; on the other hand, I was equally sure that someone had very lately been out on the small landing. So I sat down there and looked about me. I could see nothing. At last, by peering through the bars of the iron flooring, I thought I could discern a small brown object, caught in between the slats of the landing below. I climbed down there mighty quick, I can tell you, and in a moment held the butt end of a cigar in my hand. It was, as I had suspected, from the delicate odor it had left behind, one which had cost about fifty cents. I now extended my search downward, and examined every window-sill, every crevice, till I reached the basement, and, as a result of my hunt, I collected five cigar stumps, all of the same brand. From the number, I concluded that whoever had been in the apartment had been there a considerable time. From his only smoking in the kitchen or on the fire-escape, I gathered that he was anxious to leave no traces of his presence; and lastly, from the quality of his cigars, I judged him to be a man of means. So you see I had discovered, even without your assistance, that, although Miss Derwent may have told us the truth, she certainly had not told us all of it." I nodded gloomily. "What you tell me of this dark-haired woman is still more puzzling," the detective continued. "She has covered up her tracks so well that not only did I find no trace of her, but no one, not even yourself, saw her either enter or leave the building. And I should never have dreamed of her existence if I had not noticed your surprise when Miss Derwent lifted her veil. Now, the first thing to be done is to try and find this strange couple, and we will begin by tracing the man whom you saw leaving the Rosemere with a market-basket. It will be easy enough to find out if he is nothing but a local tradesman, and if he is _not_, then in all probability he is the man we want. The detective who is watching Miss Derwent----" "A detective watching Miss Derwent!" I exclaimed. "Why, yes. What did you expect? I sent one down with her to the country yesterday." Perhaps I ought to have been prepared for it, but the idea of a common fellow dogging May Derwent's footsteps, was quite a shock to me, so I inquired, with considerable ill-humor: "And what does he report?" "Nothing much. The young lady returned to her mother, as she said she would, and since then has kept to her room, but has refused to see a doctor." "Have you discovered yet who the dead man really is?" I asked, after a slight pause.
