A moment's silence, a groan, then:

"Petrie, I have dragged you into this. God forgive me—"

"Dry up, Smith," I said slowly. "I'm not a child. There is no question of being dragged into the matter. I'm here; and if I can be of any use, I'm glad I am here!"

He grasped my hand.

"There were two Chinese, in European clothes—lord, how my head throbs!—in that office door. They sand-bagged us, Petrie—think of it!—in broad daylight, within hail of the Strand! We were rushed into the car—and it was all over, before—" His voice grew faint. "God! they gave me an awful knock!"

"Why have we been spared, Smith? Do you think he is saving us for—"

"Don't, Petrie! If you had been in China, if you had seen what I have seen—"

Footsteps sounded on the flagged passage. A blade of light crept across the floor towards us. My brain was growing clearer. The place had a damp, earthen smell. It was slimy—some noisome cellar. A door was thrown open and a man entered, carrying a lantern. Its light showed my surmise to be accurate, showed the slime-coated walls of a dungeon some fifteen feet square—shone upon the long yellow robe of the man who stood watching us, upon the malignant, intellectual countenance.

It was Dr. Fu-Manchu.

At last they were face to face—the head of the great Yellow Movement, and the man who fought on behalf of the entire white race. How can I paint the individual who now stood before us—perhaps the greatest genius of modern times?
