"You took me for another person," I said, preparing to pass on. At that moment I could have sworn--I would have given one hundred to one twice over--that he was going to say Yes. To my intense astonishment, he did not. With a very visible effort he said, "No!" "Eh! What?" I exclaimed. I had taken a step or two. "No, sir." "Then what is it?" I said. "What do you want, my good fellow?" Watching his shuffling, indeterminate manner, I wondered if he were sane. His next answer reassured me on that point. There was an almost desperate deliberation about its manner. "My master wishes to see you, sir, if you will kindly walk in for five minutes," was what he said. I should have replied, "Who is your master?" if I had been wise; or cried, "Nonsense!" and gone my way. But the mind when it is spurred by a sudden emergency often overruns the more obvious course to adopt a worse. It was possible that one of my intimates had taken the house, and said in his butler's presence that he wished to see me. Thinking of that I answered, "Are you sure of this? Have you not made a mistake, my man?" With an obstinate sullenness that was new in him he said, No, he had not. Would I please to walk in? He stepped briskly forward as he spoke, and induced me by a kind of gentle urgency to enter the house, taking from me with the ease of a trained servant my hat, coat, and muffler. Finding himself in the course of his duties he gained more composure; while I, being thus treated, lost my sense of the strangeness of the proceeding, and only awoke to a full consciousness of my position when he had softly shut the door behind us and was in the act of putting up the chain. Then I confess I looked round a little alarmed at my precipitancy. But I found the hall spacious, lofty, and dark-panelled, the ordinary hall of an old London house. The big fireplace was filled with plants in flower. There were rugs on the floor and a number of chairs with painted crests on the backs, and in a corner was an old sedan chair, its poles upright against the wall. No other servants were visible, it is true. But apart from this all was in order, all was quiet, and any idea of violence was manifestly absurd. At the same time the affair seemed of the strangest. Why should the butler in charge of a well-arranged and handsome house--the house of an ordinary wealthy gentleman--why should he loiter about the open doorway as if anxious to feel the presence of his kind? Why should he show such nervous excitement and terror as I had witnessed? Why should he introduce a stranger?
