"Well, one night, Auguste, the headwaiter--you remember him, he used to get smuggled cigarettes for us; that made him suspicious; always thought everybody was a spy--pointed out a man sitting just outside the room on one of the leather-covered seats. Auguste said he came every evening and got as close as he could to our table without attracting attention; close enough, however, to hear every word that was said. If I knew the man it was all right; if I didn't know him, he suggested that I keep an eye on him. "I looked around, and saw a heavy-featured, dull-looking man about twenty-five, dressed in a good suit of well-cut clothes, shiny stove-pipe silk hat, high collar with a good deal of necktie, a big pearl pin, and a long gold watch-chain which went all around his neck like an eye-glass ribbon. He had a smooth-shaven face, two keen eyes, a flat nose, square jaw, and a straight line of a mouth. "I didn't know the man, didn't want to know him, fellows in silk hate not being popular with us, and I didn't keep an eye on him except long enough to satisfy myself that the man was only one of those hungry travellers who was adding to his stock of information by picking up the crumbs of conversation which fell from the tables, and not at all the kind of a person who would hold me or anybody else up in a _sotto portico_ or chuck me over a bridge. Then again, I was twenty pounds heavier than he was, and could take care of myself. "Some nights after this I was dining alone, none of the boys having shown up owing to a heavy rain, when Auguste nudged me, and there sat this stranger within ten feet of my table. He dropped his eyes when he saw me looking at him, and began turning the sheets of a letter he had in his hand. I was smoking one of Auguste's cigarettes, and checking the mènu with a lead-pencil, when it slipped from my hand and rolled between the man's feet. He rose, picked up the pencil, laid it beside my plate, and without a word returned to his seat, that same curious, inquisitive, hungry look on his face you saw a moment ago on that fellow's who has just gone out. Auguste, of course, lost all interest in my dinner. If he wasn't after me then he was after him; both meant trouble for Auguste. "I shifted my chair, opened the 'Gazetta' to serve as a screen, and looked the fellow over. If he were following me around to murder me, as Auguste concluded--he always had some cock-and-bull story to tell--he was certainly very polite about it. I could see that he was not an Italian, neither was he a German nor a Frenchman. He looked more like a well-to-do Dutchman--like one of those young fellows you and I used to see at the Harmonie Club in Dordrecht, or on the veranda of the Amstel, in Amsterdam. They look more like Americans than any other people in Europe.
