I think the very boldness of the trick made for its success. Surely by now all the Scorpion's slaves knew of Stephen Costigan's rebellion, knew that he was marked for death. And the very fact that I came there, inviting doom, confused the doorman. The door opened and I entered. The man who had admitted me was a tall, lank Chinaman I had known as a servant of Kathulos. He closed the door behind me and I saw we stood in a sort of vestibule, lighted by a dim lamp whose glow could not be seen from the street for the reason that the windows were heavily curtained. The Chinaman glowered at me undecided. I looked at him, tensed. Then suspicion flared in his eyes and his hand flew to his sleeve. But at the instant I was on him and his lean neck broke like a rotten bough between my hands. * * * * * I eased his corpse to the thickly carpeted floor and listened. No sound broke the silence. Stepping as stealthily as a wolf, fingers spread like talons, I stole into the next room. This was furnished in Oriental style, with couches and rugs and gold-worked drapery, but was empty of human life. I crossed it and went into the next one. Light flowed softly from the censers which were swung from the ceiling, and the Eastern rugs deadened the sound of my footfalls; I seemed to be moving through a castle of enchantment. Every moment I expected a rush of silent assassins from the doorways or from behind the curtains or screens with their writhing dragons. Utter silence reigned. Room after room I explored and at last halted at the foot of the stairs. The inevitable censer shed an uncertain light, but most of the stairs were veiled in shadows. What horrors awaited me above? But fear and the elixir are strangers and I mounted that stair of lurking terror as boldly as I had entered that house of terror. The upper rooms I found to be much like those below and with them they had this fact in common: they were empty of human life. I sought an attic but there seemed no door letting into one. Returning to the first floor, I made a search for an entrance into the basement, but again my efforts were fruitless. The amazing truth was borne in upon me: except for myself and the dead man who lay sprawled so grotesquely in the outer vestibule, there were no men in that house, dead or living.
