The Devil’s Dream by Theodore L. DeLand Jr.

DeLand was a prolific inventor of card tricks. As shown on the front cover, the additional title of this trick is What Science Can Do with a Pack of Cards. Neither title gives clues as to the nature of the trick. This folded card is the secret to the trick, but the audience is not aware of its existence. The magician shows a pack of cards and allows a spectator to cut them as many times as they wish. You say that you are going into another room and the door should be locked. You ask the audience to shout out the names of a few cards once you are out of the room. On returning, you are able to give the location of the cards called out, for example “You will find the King of Spades 16 cards from the top of the pack.”
