This is a real worker. No more crazy peek devices, impression pads or special pens. Just someone's thought.
A business card is chosen from a stack, and a spectator writes down a name, shape, number - anything on the back of the card, out of view of the magician.
The card is then inserted into an envelope - and can be held by the spectator. With no folds, tears, devices or gimmicks, you've already divined their thought using the devil's peek.
From Nathan Kranzo's 'Boondock Mental', Devil's Peek is a best-kept secret, direct from a real performer's working repertoire.
