He was a man, apparently of middle age, of middle height, clean-shaven, with good but undistinguished features, dark eyes, very clear and very bright, which showed, indeed, but little need of the pince-nez which hung by a thin black cord from his neck.

His clothes, however, were also American in cut.

His boots were narrow and of unmistakable shape.

He ate his sandwich with suspicion, and after his first sip of coffee ordered a whiskey and soda.
