Fighting down the terror that had risen in my heart and threatened to annihilate me, I once more commenced my circuit of the walls, but again without success. I counted my steps backward and forward in the hope of locating my position. I went straight ahead on the chance of striking the doorway haphazard, but it was always with the same unsatisfactory result. Against my better judgment I endeavoured to convince myself that I was really in no danger, but it was useless. At last my fortitude gave way, a clammy sweat broke out upon my forehead, and remembering that Pharos was in the building, I shouted aloud to him for help. My voice rang and echoed in that ghastly chamber till the reiteration of it well-nigh drove me mad. I listened, but no answer came. Once more I called, but with the same result. At last, thoroughly beside myself with terror, I began to run aimlessly about the room in the dark, beating myself against the walls and all the time shouting at the top of my voice for assistance. Only when I had no longer strength to move, or voice to continue my appeals, did I cease, and falling upon the ground rocked myself to and fro in silent agony. Times out of number I cursed myself and my senseless stupidity in having left the hotel to follow Pharos. I had sworn to protect the woman I loved, and yet on the first opportunity I had ruined everything by behaving in this thoughtless fashion. Once more I sprang to my feet and once more I set off on my interminable search. This time I went more quietly to work, feeling my way carefully and making a mental note of every indentation in the walls. Being unsuccessful, I commenced again, and once more scored a failure. Then the horrible silence, the death-like atmosphere, the flapping of the bats in the darkness, and the thought of the history and age of the place in which I was imprisoned, must have affected my brain, and for a space I believe I went mad. At any rate, I have a confused recollection of running round and round that loathsome place and of at last falling exhausted upon the ground, firmly believing my last hour had come. Then my senses left me and I became unconscious. How long I remained in the condition I have just described I can not say. All I know is that when I opened my eyes I found the chamber bright with the light of torches, and no less a person than Pharos kneeling beside me. Behind him, but at a respectful distance, were a number of Arabs, and among them a man whose height could scarcely have been less than seven feet. This was evidently the individual who had met Pharos at the entrance to the Pyramid.
