Subsequent inquiries made by Scotland Yard through the authorities in India established the fact that the sapphire eye of the image in Tibet had been stolen; that Mr. Ratcliffe was in Tibet at the time; and that not long after the tragedy in Blenheim Square the jewel was restored to its place with much rejoicing and religious enthusiasm. I was not disposed to like Professor Quarles nor to believe in him altogether. I found it easy to see the charlatan in him, yet the fact remained that he had solved the problem. Certainly he was interesting, and, besides, there was his granddaughter, Zena. If only for the sake of seeing her, I felt sure I should have occasion to consult Christopher Quarles again. CHAPTER II THE IDENTITY OF THE FINAL VICTIM I soon fell into the habit of going to see Professor Quarles. As an excuse I talked over cases with him, but he seldom volunteered an opinion, often was obviously uninterested. Truth to tell, I was not there for his opinion, but to see his granddaughter. A detective in love sounds something like an absurdity, but such was my case, and, since Zena's manner did not suggest that she was particularly interested in me, my love affair seemed rather a hopeless one. My association with Christopher Quarles has, however, led to the solution of some strange mysteries, and, since my own achievements are sufficiently well known, I may confine myself to those cases which, single-handed, I should have failed to solve. I know that in many of them I was credited with having unraveled the mystery, but this was only because Professor Quarles persisted in remaining in the background. If I did the spade work, the deductions were his. They were all cases with peculiar features in them, and it was never as a detective that Quarles approached them. He was often as astonished at my acumen in following a clew as I was at his marvelous theories, which seemed so absurd to begin with yet proved correct in the end. Perhaps his curious power was never more noticeable than in the case of the Withan murder. A farmer returning from Medworth, the neighboring market town, one night in January, was within a quarter of a mile of Withan village when his horse suddenly shied and turned into the ditch. During the afternoon there had been a fall of snow, sufficient to cover the ground to a depth of an inch or so, and in places it had drifted to a depth of two feet or more. By evening the clouds had gone, the moon sailed in a clear sky, and, looking round to find the cause of his horse's unusual behavior, the farmer saw a man lying on a heap of snow under the opposite hedge. He was dead--more, he was headless.
