Again I detected the appeal to a hidden Audience; and there was something very uncanny in the idea. The house now was deathly still; the ringing had entirely subsided. In the upper corridor my companion, who seemed to be well acquainted with the position of the switches, again turned up all the lights, and in pursuit of the strange comedy which he saw fit to enact, addressed me continuously in the loud and unnatural voice which he had adopted as part of his disguise. We looked into a number of rooms all well and comfortably furnished, but although my imagination may have been responsible for the idea, they all seemed to possess a chilly and repellent atmosphere. I felt that to essay sleep in any one of them would be the merest farce, that the place to all intents and purposes was uninhabitable, that something incalculably evil presided over the house. And through it all, so obtuse was I that no glimmer of the truth entered my mind. Outside again in the long, brightly lighted corridor, we stood for a moment as if a mutual anticipation of some new event pending had come to us. It was curious--that sudden pulling up and silent questioning of one another; because, although we acted thus, no sound had reached us. A few seconds later our anticipation was realized. From the direction of the stairs it came--a low wailing in a woman's voice; and the sweetness of the tones added to the terror of the sound. I clutched at Smith's arm convulsively whilst that uncanny cry rose and fell--rose and fell--and died away. Neither of us moved immediately. My mind was working with feverish rapidity and seeking to run down a memory which the sound had stirred into faint quickness. My heart was still leaping wildly when the wailing began again, rising and falling in regular cadence. At that instant I identified it. During the time Smith and I had spent together in Egypt, two years before, searching for Karamaneh, I had found myself on one occasion in the neighbourhood of a native cemetery near to Bedrasheen. Now, the scene which I had witnessed there rose up again vividly before me, and I seemed to see a little group of black-robed women clustered together about a native grave; for the wailing which now was dying away again in The Gables was the same, or almost the same, as the wailing of those Egyptian mourners. The house was very silent, now. My forehead was damp with perspiration, and I became more and more convinced that the uncanny ordeal must prove too much for my nerves. Hitherto, I had accorded little credence to tales of the supernatural, but face to face with such manifestations as these, I realized that I would have faced rather a group of armed dacoits, nay! Dr. Fu-Manchu himself, than have remained another hour in that ill-omened house. My companion must have read as much in my face. But he kept up the strange and, to me, purposeless comedy when presently he spoke.
