"It was really done as an experiment," he said. "I am not a card-sharper
by profession, as some of you already know. But in the course of certain
investigations not connected with the matter I now have in hand, I
picked this thing up, and, being something of a specialist in certain
forms of cheating, I made up my mind to try my hand at this and prove

take it--on behalf of these other gentlemen also, that your action was a
most dastardly piece of impertinence, to give it its tamest name.
