The din of distant drumming came to my ears.

"Where in Heaven's name are we?" hissed Smith in my ear; "that is a tom-tom!"

"S-sh! S-sh!"

The little hand grasping mine quivered nervously. We were near a door or a window, for a breath of perfume was wafted through the air; and it reminded me of my other meetings with the beautiful woman who was now leading us from the house of Fu-Manchu; who, with her own lips, had told me that she was his slave. Through the horrible phantasmagoria she flitted—a seductive vision, her piquant loveliness standing out richly in its black setting of murder and devilry. Not once, but a thousand times, I had tried to reason out the nature of the tie which bound her to the sinister Doctor.

Silence fell.

"Quick! This way!"

Down a thickly carpeted stair we went. Our guide opened a door, and led us along a passage. Another door was opened; and we were in the open air. But the girl never tarried, pulling me along a graveled path, with a fresh breeze blowing in my face, and along until, unmistakably, I stood upon the river bank. Now, planking creaked to our tread; and looking downward beneath the handkerchief, I saw the gleam of water beneath my feet.

"Be careful!" I was warned, and found myself stepping into a narrow boat—a punt.

Nayland Smith followed, and the girl pushed the punt off and poled out into the stream.

"Don't speak!" she directed.
