I overtook him as he threw wide the door of my dispensing room. Through he ran and opened the door at the other end. I followed him out, closing it behind me. The smell from some tobacco plants in a neighbouring flower-bed was faintly perceptible; no breeze stirred; and in the great silence I could hear Smith, in front of me, tugging at the bolt of the gate. Then he had it open, and I stepped out, close on his heels, and left the door ajar. "We must not appear to have come from your house," explained Smith rapidly. "I will go along to the high-road and cross to the common a hundred yards up, where there is a pathway, as though homeward bound to the north side. Give me half a minute's start, then you proceed in an opposite direction and cross from the corner of the next road. Directly you are out of the light of the street lamps, get over the rails and run for the elms!" He thrust a pistol into my hand and was off. While he had been with me, speaking in that incisive impetuous way of his, his dark face close to mine, and his eyes gleaming like steel, I had been at one with him in his feverish mood, but now, when I stood alone in that staid and respectable by-way, holding a loaded pistol in my hand, the whole thing became utterly unreal. It was in an odd frame of mind that I walked to the next corner, as directed, for I was thinking, not of Dr. Fu-Manchu, the great and evil man who dreamed of Europe and America under Chinese rule, not of Nayland Smith, who alone stood between the Chinaman and the realization of his monstrous schemes, not even of Karamaneh, the slave girl, whose glorious beauty was a weapon of might in Fu-Manchu's hand, but of what impression I must have made upon a patient had I encountered one then. Such were my ideas up to the moment that I crossed to the common and vaulted into the field on my right. As I began to run toward the elms I found myself wondering what it was all about, and for what we were come. Fifty yards west of the trees it occurred to me that if Smith had counted on cutting Forsyth off we were too late, for it appeared to me that he must already be in the coppice. I was right. Twenty paces more I ran, and ahead of me, from the elms, came a sound. Clearly it came through the still air--the eerie hoot of a nighthawk. I could not recall ever to have heard the cry of that bird on the common before, but oddly enough I attached little significance to it until, in the ensuing instant, a most dreadful scream--a scream in which fear and loathing and anger were hideously blended--thrilled me with horror. After that I have no recollection of anything until I found myself standing by the southernmost elm. "Smith!" I cried breathlessly. "Smith! my God! where are you?"
