"There was a woman at this strange gathering, Petrie. Heaven only knows who she really is. According to Fu-Manchu she is that woman of mystery concerning whose existence strange stories are current in the East; the future Empress of a universal empire! But of course I decline to accept the story, Petrie! if ever the Yellow races overran Europe, I am in no doubt respecting the identity of the person who would ascend the throne of the world!"

"Nor I, Smith!" I cried excitedly. "Good God! he holds them all in the palm of his hand! He has welded together the fanatics of every creed of the East into a giant weapon for his personal use! Small wonder that he is so formidable. But, Smith—who is that woman?"

"Petrie!" he said slowly, and I knew that I had betrayed my secret,
"Petrie—where did you learn all this?"

I returned his steady gaze.

"I was present at the meeting of the Si-Fan," I replied steadily.

"What? What? You were present?"

"I was present! Listen, and I will explain."

Standing there in the hallway I related, as briefly as possible, the astounding events of the night. As I told of the woman in the train—

"That confirms my impression that Fu-Manchu was imposing upon the others!" he snapped. "I cannot conceive of a woman recluse from some Lamaserie, surrounded by silent attendants and trained for her exalted destiny in the way that the legendary veiled woman of Tibet is said to be trained, traveling alone in an English railway carriage! Did you observe, Petrie, if her eyes were oblique at all?"

"They did not strike me as being oblique. Why do you ask?"
