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. My brain was fevered; I scarce knew if I dreamed and was waking, or if the reality ended with my imprisonment in the clammy cellar and this silent escape, blindfolded, upon the river with a girl for our guide who might have stepped out of the pages of "The Arabian Nights" were fantasy--the mockery of sleep. Indeed, I began seriously to doubt if this stream whereon we floated, whose waters plashed and tinkled about us, were the Thames, the Tigris, or the Styx. The punt touched a bank. "You will hear a clock strike in a few minutes," said the girl, with her soft, charming accent, "but I rely upon your honor not to remove the handkerchiefs until then. You owe me this." "We do!" said Smith fervently. I heard him scrambling to the bank, and a moment later a soft hand was placed in mine, and I, too, was guided on to terra firma. Arrived on the bank, I still held the girl's hand, drawing her towards me. "You must not go back," I whispered. "We will take care of you. You must not return to that place." "Let me go!" she said. "When, once, I asked you to take me from him, you spoke of police protection; that was your answer, police protection! You would let them lock me up--imprison me--and make me betray him! For what? For what?" She wrenched herself free. "How little you understand me. Never mind. Perhaps one day you will know! Until the clock strikes!" She was gone. I heard the creak of the punt, the drip of the water from the pole. Fainter it grew, and fainter. "What is her secret?" muttered Smith, beside me. "Why does she cling to that monster?"
