Then it occurred to me that the Arabs might be ready to meet and attack me at the entrance upon any evidence of my probable escape from the binding cords, as would be furnished by any decided agitation of the rope which they probably held. This, of course, was taking for granted that my place of confinement was indeed Khephren's Temple of the Sphinx. The direct opening in the roof, wherever it might lurk, could not be beyond easy reach of the ordinary modern entrance near the Sphinx; if in truth it were any great distance at all on the surface, since the total area known to visitors is not at all enormous. I had not noticed any such opening during my daytime pilgrimage, but knew that these things are easily overlooked amidst the drifting sands. Thinking these matters over as I lay bent and bound on the rock floor, I nearly forgot the horrors of abysmal descent and cavernous swinging which had so lately reduced me to a coma. My present thought was only to outwit the Arabs, and I accordingly determined to work myself free as quickly as possible, avoiding any tug on the descending line which might betray an effective or even problematical attempt at freedom.
