Five minutes after he had gone, I left my room and strolled to the head of the stairs. As I had expected, a gentleman was seated upon the lounge that faced the door of the elevator, I could not see his face for it was concealed behind a newspaper. But I marked one incongruous circumstance in his apparel. He wore evening dress, and ordinary street boots of black leather. I am afraid I was so vulgar as to permit myself the indulgence of a wink. I passed him and leisurely descended the first flight of stairs. Of a sudden I stopped, and turning about ran upstairs again at the top of my speed, taking three steps at a time. My gentleman had already begun to descend the stairs. I passed him without a glance, swearing in a low but audible key at my forgetfulness. In another moment I was back in my room pressing the electric button. "So!" thought I, "they have employed a detective to shadow me. Well, we shall see!"
Presently a knock sounded on the door, and the waiter entered, who had shown Sir Charles out.
"Shut it," I said. He obeyed.
"What is your name?" I demanded.
"Martin, sir."
"Well, look here, Martin," said I, "my old friend Sir Charles Venner has just bet me a hundred pounds that I cannot succeed in getting out of this hotel in some disguise, without his suspecting me, during the next half hour. Now he is waiting in the vestibule, is he not?"
The waiter grinned. "No, sir, just inside the coffee room door; I was wondering what he wanted. He gave me half a crown, sir."
"Half a crown!" I sneered. "Look here Martin——" I took Sir Charles' own roll from my pocket and selected two brand new five pound notes. "Now Sir Charles thinks himself very smart, and he fancies he can see through a disguise in a second. But I reckon a bit on my smartness too, for when I was a young man before I made a fortune out of mining I was on the stage. With your help, my man, I'll do Sir Charles up, do him brown—and these notes will be yours for helping me!"
Martin's eyes almost burst out of their sockets. "All right, sir!" he cried excitedly. "What do you want me to do?"
"Exchange clothes with me for ten minutes. Here are the notes, my man—I'll pay you beforehand. All I'll have to do to win my bet is to slip out of the house and return. Hurry up, Martin!"
