How I arrived gaily at this monstrous conclusion seems to me now a mystery; but the truth is that from a conversation one brings away a general idea that is larger than the words actually heard and spoken. I have reported, naturally, but a fragment of what passed between us in language, and of what was suggested--by gesture, expression, silence--merely perhaps a hint. I can only assert that this troubling verdict remained a conviction in my mind. It came upstairs with me; it watched and listened by my side. That mysterious Third evoked in our conversation was bigger than either of us separately; it might be called the spirit of ancient Egypt, or it might be called with equal generalisation, the Past. This Third, at any rate, stood by me, whispering this astounding thing. I went out on to my little balcony to smoke a pipe and enjoy the comforting presence of the stars before turning in. It came out with me. It was everywhere. I heard the barking of dogs, the monotonous beating of a distant drum towards Bedraschien, the sing-song voices of the natives in their booths and down the dim-lit streets. I was aware of this invisible Third behind all these familiar sounds. The enormous night-sky, drowned in stars, conveyed it too. It was in the breath of chilly wind that whispered round the walls, and it brooded everywhere above the sleepless desert. I was alone as little as though George Isley stood beside me in person--and at that moment a moving figure caught my eye below. My window was on the sixth story, but there was no mistaking the tall and soldierly bearing of the man who was strolling past the hotel. George Isley was going slowly out into the desert. There was actually nothing unusual in the sight. It was only ten o’clock; but for doctor’s orders I might have been doing the same myself. Yet, as I leaned over the dizzy ledge and watched him, a chill struck through me, and a feeling nothing could justify, nor pages of writing describe, rose up and mastered me. His words at dinner came back with curious force. Egypt lay round him, motionless, a vast grey web. His feet were caught in it. It quivered. The silvery meshes in the moonlight announced the fact from Memphis up to Thebes, across the Nile, from underground Sakkhâra to the Valley of the Kings. A tremor ran over the entire desert, and again, as in the dining-room, the leagues of sand went rustling. It seemed to me that I caught him in the act of disappearing.
