Melville Davisson Post,
The Sleuth of St. James's Square
“ If a man was a tanner, and especially a foreign, hand-workin' tanner, what would his markin's be? “'I tried to remember everybody that I'd ever seen handlin' a hide, and all at once I recollected that the first thing a dago shoemaker done when he picked up a piece of leather was to smooth it out with his thumbs. An' I said to myself, now that'll be what a tanner does, only he does it more.... he's always doin' it. Then I asks myself what would be the markin's?' “The hobo paused, his mouth open, his head twisted to one side. Then he jerked up as under a released spring. ”
