The performer Kreskin, the self-styled ""mentalist,"" has been touring TV prime-time shows with mind reading, suggestion (he's nervous about the word ""hypnotism,"" now banned from TV), and take-a-card magic. His acts are truly marvelous, and no one is more aware of this than Mr. Kreskin -- like all the greats in the trade he flaps his ego but buttons his beak when it comes to telling how. What went on before his mother returned home to find her other son levitated three feet off the floor in a lotus position we'll never know. As for the mind reading, Kreskin bobs in and out of theory while reminding the reader that his demonstrations prove not so much the scientific possibilities of ESP but ""the particular skills of the performer."" This is mainly a parade of successful exhibitions and anecdotes about Kreskin and the celebrities he has amazed. You won't learn a thing but you'll gawk just the same.
