Four raps on the under side of the floor, and a moment later I stood in the idol-room. I gasped in amazement—the fact that across a table from me sat Kathulos in all his horror was not the cause of my exclamation. Except for the table, the chair on which the Skull-face sat and the altar—now bare of incense—the room was perfectly bare! Drab, unlovely walls of the unused warehouse met my gaze instead of the costly tapestries I had become accustomed to. The palms, the idol, the lacquered screen—all were gone.
"Ah, Mr. Costigan, you wonder, no doubt."
The dead voice of the Master broke in on my thoughts. His serpent eyes glittered balefully. The long yellow fingers twined sinuously upon the table.
"You thought me to be a trusting fool, no doubt!" he rapped suddenly. "Did you think I would not have you followed? You fool, Yussef Ali was at your heels every moment!"
An instant I stood speechless, frozen by the crash of these words against my brain; then as their import sank home, I launched myself forward with a roar. At the same instant, before my clutching fingers could close on the mocking horror on the other side of the table, men rushed from every side. I whirled, and with the clarity of hate, from the swirl of savage faces I singled out Yussef Ali, and crashed my right fist against his temple with every ounce of my strength. Even as he dropped, Hassim struck me to my knees and a Chinaman flung a man-net over my shoulders. I heaved erect, bursting the stout cords as if they were strings, and then a blackjack in the hands of Ganra Singh stretched me stunned and bleeding on the floor.
Lean sinewy hands seized and bound me with cords that cut cruelly into my flesh. Emerging from the mists of semi-unconsciousness, I found myself lying on the altar with the masked Kathulos towering over me like a gaunt ivory tower. About in a semicircle stood Ganra Singh, Yar Khan, Yun Shatu and several others whom I knew as frequenters of the Temple of Dreams. Beyond them—and the sight cut me to the heart—I saw Zuleika crouching in a doorway, her face white and her hands pressed against her cheeks, in an attitude of abject terror.
"I did not fully trust you," said Kathulos sibilantly, "so I sent Yussef Ali to follow you. He reached the group of trees before you and following you into the estate heard your very interesting conversation with John Gordon—for he scaled the house-wall like a cat and clung to the window-ledge! Your driver delayed purposely so as to give Yussef Ali plenty of time to get back—I have decided to change my abode anyway. My furnishings are already on their way to another house, and as soon as we have disposed of the traitor—you!—we shall depart also, leaving a little surprize for your friend Gordon when he arrives at five-thirty."
My heart gave a sudden leap of hope. Yussef Ali had misunderstood, and Kathulos lingered here in false security while the London detective force had already silently surrounded the house. Over my shoulder I saw Zuleika vanish from the door.
I eyed Kathulos, absolutely unaware of what he was saying. It was not long until five—if he dallied longer—then I froze as the Egyptian spoke a word and Li Kung, a gaunt, cadaverous Chinaman, stepped from the silent semicircle and drew from his sleeve a long thin dagger. My eyes sought the timepiece that still rested on the table and my heart sank. It was still ten minutes until five. My death did not matter so much, since it simply hastened the inevitable, but in my mind's eye I could see Kathulos and his murderers escaping while the police awaited the stroke of five.
The Skull-face halted in some harangue, and stood in a listening attitude. I believe his uncanny intuition warned him of danger. He spoke a quick staccato command to Li Kung and the Chinaman sprang forward, dagger lifted above my breast.
