I was assisted from the step on to the pavement--and I heard the car being driven back. Having slowly counted thirty I opened my eyes, and looked about me. This, and not the fevered moment when first I had looked upon the room with the golden door, seemed to be my true awakening, for about me was comprehensible world, the homely streets of London, with deserted Portland Place stretching away on the one hand and a glimpse of midnight Regent Street obtainable on the other! The clock of the neighboring church struck one. My mind yet dull with wonder of it all, I walked on to Oxford Circus and there obtained a taxicab, in which I drove to Fleet Street. Discharging the man, I passed quickly under the time worn archway into the court and approached our stair. Indeed, I was about to ascend when some one came racing down and almost knocked me over. "Petrie! Petrie! Thank God you're safe!" It was Nayland Smith, his eyes blazing with excitement, as I could see by the dim light of the lamp near the archway, and his hands, as he clapped them upon my shoulders, quivering tensely. "Petrie!" he ran on impulsively, and speaking with extraordinary rapidly, "I was detained by a most ingenious trick and arrived only five minutes ago, to find you missing, the window wide open, and signs of hooks, evidently to support a rope ladder, having been attached to the ledge." "But where were you going?" "Weymouth has just rung up. We have indisputable proof that the mandarin Ki-Ming, whom I had believed to be dead, and whom I know for a high official of the Si-Fan, is actually in London! It's neck or nothing this time, Petrie! I'm going straight to Portland Place!" "To the Chinese Legation?" "Exactly!" "Perhaps I can save you a journey," I said slowly. "I have just come from there!" CHAPTER XXVIII THE MANDARIN KI-MING Nayland Smith strode up and down the little sitting-room, tugging almost savagely at the lobe of his left ear. To-night his increasing grayness was very perceptible, and with his feverishly bright eyes staring straightly before him, he looked haggard and ill, despite the deceptive tan of his skin. "Petrie," he began in his abrupt fashion, "I am losing confidence in myself." "Why?" I asked in surprise. "I hardly know; but for some occult reason I feel afraid." "Afraid?" "Exactly; afraid. There is some deep mystery here that I cannot fathom. In the first place, if they had really meant you to remain ignorant of the place at which the episodes described by you occurred, they would scarcely have dropped you at the end of Portland Place." "You mean ...?" "I mean that I don't believe you were taken to the Chinese Legation at all. Undoubtedly you saw the mandarin Ki-Ming; I recognize him from your description." "You have met him, then?" "No; but I know those who have. He is undoubtedly a very dangerous man, and it is just possible----" He hesitated, glancing at me strangely.
