"Lost sight of it! Confound it, you have to look at it and see what it is."
"Oh, you want me to look at the front of it!"
"Why, of course! Now then, pick a card."
"All right. I've picked it. Go ahead." (Shuffle, shuffle, shuffle—flip.)
"Say, confound you, did you put that card back in the pack?"
"Why, no. I kept it."
"Holy Moses! Listen. Pick—a—card—just one—look at it—see what it is—then put it back—do you understand?"
"Oh, perfectly. Only I don't see how you are ever going to do it. You must be awfully clever."
(Shuffle, shuffle, shuffle—flip.)
"There you are; that's your card, now, isn't it?" (This is the supreme moment.)
