Paul Campenhaye, Specialist in Criminology

It was the fourth day of October, 19—, and three o’clock in the afternoon. Killingley, my clerk, had just come back from his lunch. I heard him moving about in his room—the first of the three rooms in which I carried on my business in Jermyn Street. As for myself, I was reading a new essay on certain characteristics of Napoleon Bonaparte; it was clever and, in many respects, original, and I had no wish to be disturbed. But just then the outer bell rang.Killingley came in a moment later.“A lady wishes to see you, sir,” he said.“In the usual way, Killingley,” I said, rising.Now, I had a habit, during the comparatively short time in which I carried on the business, of taking care to see my clients before they saw me. I have said that I occupied three rooms; the first was used by Killingley as a sort of office, and contained himself, an American roll-top desk, a typewriter, and Killingley’s collection of light literature; the second was fitted up as a luxurious waiting-room; the third was my own apartment. And between it and the second was a cunningly-devised and quite secret arrangement by which I, unseen, could take minute stock of any person who called upon me. Often I kept clients waiting impatiently in that room while I watched and studied them; I was all the more ready for them when I admitted them to my presence.
