She slipped from her place, kissed me on both eyes, and ran across to the door of the inner room. She looked back at me only for a moment, opened her lips, said nothing, and disappeared, closing the door softly behind her. I mixed myself the stiffest whisky and soda I had ever concocted in my life, lit a cigar from a box I found on the sideboard, and sat down to watch the clock. At five minutes to three, I was walking up and down the room with my overcoat on. At a minute to the hour, as I stood with my eyes glued to the clock, the inner door softly opened. Naida stood framed upon the threshold. There was a look of distress upon her face. "Monsieur Maurice," she said, "I had made up my mind to say nothing, but that was wrong. You are a very honourable young man and I have not met many. It has been promised to me that no harm shall come to you, but yet--go warily to the lift." She disappeared and closed the door. For the first time she locked it. Somehow, I felt, as I stepped out into the corridor, that the dangers which might be waiting for me were small things. I stood for several seconds, looking up and down. To reach the lift I had to traverse the whole of the corridor, turn to the left and pass along another shorter one. I stepped out carelessly enough, and then--the scantily lit passage seemed suddenly filled with whispering voices, with eyes peering at me from mysterious corners; the soft carpets behind me were reverberant with muffled and stealthy footsteps. I was acutely conscious of the presence of danger. As I neared the corner of the corridor every nerve of my body was bristling with apprehension. Before I turned, I paused for a moment and looked behind. There was only a single electric lamp burning, but I could see dimly along the empty space to the end. There was no sign of any moving figure, nor any sound. Then I turned the corner to find myself suddenly seized in a pair of giant arms, the dull flicker of upraised steel before my eyes, the sallow, brutelike face, the black, flaming eyes of the man who had watched me from the lounge, within an inch or two of me. I had no chance to call out. My assailant's left hand was upon my throat. I could see him gathering strength to drive that knife down into my heart. My brain was perfectly active. I waited with tense muscles for the terrible moment, meaning to fling myself on one side in the hope that I might escape mortal injury from that first blow, at any rate. And then I saw something loom up behind. I saw an arm raised even higher than my captor's, and I heard the wickedest sound in life--the crash of dull metal into a man's skull. The grasp upon my throat was instantly relaxed, doors were thrown open along the corridor, and I sank back into a momentary fit of unconsciousness. * * * * *
