If only I could have addressed this utterly mysterious stranger, have uttered some word of commonplace, I felt that the spell might have been broken. But, for some occult reason, in no way associated with my first rebuff, I found myself tongue-tied; I sustained, for an hour (the longest I had ever known), a silent watch and ward over my reason; I seemed to be repelling, fighting against, some subtle power that sought to flood my brain, swamp my individuality, and enslave me to another's will.

In what degree this was actual, and in what due to a mind overwrought from endless conflict with the Yellow group, I know not to this day, but you who read these records of our giant struggle with Fu-Manchu and his satellites shall presently judge for yourselves.

When, at last, the brakes were applied, and the pillars and platforms of the great terminus glided into view, how welcome was the smoky glare, how welcome the muffled roar of busy London!

A huge negro—the double of the man I had overthrown—opened the door of the compartment, bestowing upon me a glance in which enmity and amazement were oddly blended, and the woman, drawing the cloak about her graceful figure, stood up composedly.

She reached for a small leather case on the rack, and her loose sleeve fell back, to reveal a bare arm—soft, perfectly molded, of the even hue of old ivory. Just below the elbow a strange-looking snake bangle clasped the warm-flesh; the eyes; dull green, seemed to hold a slumbering fire—a spark—a spark of living light.

Then—she was gone!

"Thank Heaven!" I muttered, and felt like another Dante emerging from the Hades.

As I passed out of the station, I had a fleeting glimpse of a gray figure stepping into a big car, driven by a black chauffeur.
