My American acquaintance having returned to his seat and having added a very little water to the whisky went on:

“Now, sir,” said he, “my name is Colin Camber, formerly of Richmond, Virginia, United States of America, but now of the Guest House, Surrey, England, at your service.”

Taking my cue from Mr. Camber’s gloomy but lofty manner, I bowed formally and mentioned my name.

“I am delighted to make your acquaintance, Mr. Knox,” he assured me; “and now, sir, to answer your question. When you came in a few moments ago you glanced at me. Your eyes did not open widely as is the case when one recognizes, or thinks one recognizes, an acquaintance, they narrowed. This indicated retrospection. For a moment they turned aside. You were focussing a fugitive idea, a memory. You captured it. You looked at me again, and your successive glances read as follows: The hair worn uncommonly long, the mathematical brow, the eyes of a poet, the slight moustache, small mouth, weak chin; the glass at his elbow. The resemblance is complete. Knowing how complete it is myself, sir, I ventured to test my theory, and it proved to be sound.”

Now, as Mr. Colin Camber had thus spoken in the serious manner of a slightly drunken man, I had formed the opinion that I stood in the presence of a very singular character. Here was that seeming mésalliance which not infrequently begets genius: a powerful and original mind allied to a weak will. I wondered what Mr. Colin Camber’s occupation might be, and somewhat, too, I wondered why his name was unfamiliar to me. For that the possessor of that brow and those eyes could fail to make his mark in any profession which he might take up I was unwilling to believe.

“Your exposition has been very interesting, Mr. Camber,” I said. “You are a singularly close observer, I perceive.”

“Yes,” he replied, “I have passed my life in observing the ways of my fellowmen, a study which I have pursued in various parts of the world without appreciable benefit to myself. I refer to financial benefit.”

He contemplated me with a look which had grown suddenly pathetic.

“I would not have you think, sir,” he added, “that I am an habitual toper. I have latterly been much upset by—domestic worries, and—er—” He emptied his glass at a draught. “Surely, Mr. Knox, you are going to replenish? Whilst you are doing so, would you kindly request Mrs. Wootton to extend the same favour to myself?”

But at that moment Mrs. Wootton in person appeared behind the counter. “Time, please, gentlemen,” she said; “it is gone half-past two.”
