Although the man's back was turned toward me, I was uncomfortably conscious that he was watching me. How he could possibly be watching me while I stood directly behind him, I did not ask myself; yet, nevertheless, instinct warned me that I was being inspected; that somehow or other the man was staring at me as steadily as though he and I had been face to face and his faded, sea-green eyes were focussed upon me. It was an odd sensation which persisted in spite of logic, and of which I could not rid myself. Yet the little waitress did not seem to share it. Perhaps she was not under his glassy inspection. But then, of course, I could not be either.
