Great as was my mental disturbance, I managed to grasp the purpose of this device. The very extremity of my danger found me cool. I fastened the manacles, which so recently had confined my own wrists, upon the slim wrists of Kâramanèh. A faint and muffled disturbance, doubly ominous because there was nothing to proclaim its nature, reached me from some place below, on the ground floor.

"Tie something around my mouth!" directed Kâramanèh with nervous rapidity. As I began to look about me: "Tear a strip from my dress," she said; "do not hesitate—be quick! be quick!"

I seized the flimsy muslin and tore off half a yard or so from the hem of the skirt. The voice of Dr. Fu-Manchu became audible. He was speaking rapidly, sibilantly, and evidently was approaching—would be upon me in a matter of moments. I fastened the strip of fabric over the girl's mouth and tied it behind, experiencing a pang half pleasurable and half fearful as I found my hands in contact with the foamy luxuriance of her hair.

Dr. Fu-Manchu was entering the room immediately beyond.

Snatching up the bunch of keys, I turned and ran, for in another instant my retreat would be cut off. As I burst once more into the darkened room I became aware that a door on the farther side of it was open; and framed in the opening was the tall high-shouldered figure of the Chinaman, still enveloped in his fur coat and wearing the grotesque cap. As I saw him, so he perceived me; and as I sprang to the window, he advanced.

I turned desperately and hurled the bunch of keys with all my force into the dimly seen face....

Either because they possessed a chatoyant quality of their own (as I had often suspected), or by reason of the light reflected through the open window, the green eyes gleamed upon me vividly like those of a giant cat. One short guttural exclamation paid tribute to the accuracy of my aim; then I had the crossbar in my hand.

I threw one leg across the sill, and dire as was my extremity, hesitated for an instant ere trusting myself to the flight....

A vice-like grip fastened upon my left ankle.

Hazily I became aware that the dark room was become flooded with figures. The whole yellow gang were upon me—the entire murder-group composed of units recruited from the darkest places of the East!
