I replaced my matches in my pocket and returned to the front of the cab, making a gesture as of one raising a glass to his lips and jerking my thumb across my shoulder in the direction of my unseen fare. "Oh, that's it!" said the constable, and moved off. Never in my whole career have I been so glad to see the back of any man! I drove on slowly. The point for which I was making was only some three hundred yards further along, but I had noted that the constable had walked off in the opposite direction. Therefore, arriving at my destination--a vacant wharf open to the road--I pulled up and listened. Only the wash of the tide upon the piles of the wharf was audible, for the night was now far advanced. I opened the door of the cab and dragged out "Le Balafre." Right and left I peered, truly like a stage villain, and then hauled my unpleasant burden along the irregularly paved path and on to the little wharf. Out in mid-stream a Thames Police patrol was passing, and I stood for a moment until the creak of the oars grew dim. Then: there was a dull splash far below ... and silence again. Gaston Max had been consigned to a watery grave! Returning again to the garage, I wondered very much who he had been, this one, "Le Balafre." Could it be that he was "The Scorpion"? I could not tell, but I had hopes very shortly of finding out. I had settled up my affairs with my landlady and had removed from my apartments all papers and other effects. In the garage I had placed a good suit of clothes and other necessities, and by telephone I had secured a room at a West-End hotel. The cab returned to the stable, I locked the door, and by the light of one of the lamps, shaved off my beard and moustache. My uniform and cap I hung up on the hook where I usually left them after working hours, and changed into the suit which I had placed there in readiness. I next destroyed all evidences of identity and left the place in a neat condition. I extinguished the lamp, went out and locked the door behind me, and carrying a travelling-grip and a cane I set off for my new hotel. Charles Malet had disappeared! CHAPTER IV I MEET AN OLD ACQUAINTANCE On the corner opposite Dr. Stuart's establishment stood a house which was "to be let or sold." From the estate-agent whose name appeared upon the notice-board I obtained the keys--and had a duplicate made of that which opened the front door. It was a simple matter, and the locksmith returned both keys to me within an hour. I informed the agent that the house would not suit me.
