They had seen us! Fu-Manchu's guttural voice spoke shortly—and our screw began to revolve again; we leaped ahead into the bank of darkness. Faint grew the light of the police launch—and was gone. But I heard Ryman's voice shouting.

"Full speed!" came faintly through the darkness. "Port! Port!"

Then the murk closed down, and with our friends far astern of us we were racing deeper into the fog banks—speeding seaward; though of this I was unable to judge at the time.

On we raced, and on, sweeping over growing swells. Once, a black, towering shape dropped down upon us. Far above, lights blazed, bells rang, vague cries pierced the fog. The launch pitched and rolled perilously, but weathered the wash of the liner which so nearly had concluded this episode. It was such a journey as I had taken once before, early in our pursuit of the genius of the Yellow Peril; but this was infinitely more terrible; for now we were utterly in Fu-Manchu's power.

A voice mumbled in my ear. I turned my bound-up face; and Inspector Weymouth raised his hands in the dimness and partly slipped the bandage from his mouth.

"I've been working at the cords since we left those filthy cellars," he whispered. "My wrists are all cut, but when I've got out a knife and freed my ankles—"

Smith had kicked him with his bound feet. The detective slipped the bandage back to position and placed his hands behind him again. Dr. Fu-Manchu, wearing a heavy overcoat but no hat, came aft. He was dragging Karamaneh by the wrists. He seated himself on the cushions near to us, pulling the girl down beside him. Now, I could see her face—and the expression in her beautiful eyes made me writhe.

Fu-Manchu was watching us, his discolored teeth faintly visible in the dim light, to which my eyes were becoming accustomed.

"Dr. Petrie," he said, "you shall be my honored guest at my home in China. You shall assist me to revolutionize chemistry. Mr. Smith, I fear you know more of my plans than I had deemed it possible for you to have learned, and I am anxious to know if you have a confidant. Where your memory fails you, and my files and wire jackets prove ineffectual, Inspector Weymouth's recollections may prove more accurate."

He turned to the cowering girl—who shrank away from him in pitiful, abject terror.
