Kennedy is one of the best up-and-coming UK mentalists. This book, his first, is loaded with sage wisdom about using off-the-cuff performances to build your reputation and get jobs. Ken speaks from experience, and his essays are spot-on. He then outlines his impromptu routine, which--if memory serves me--has five effects. They are all at least good, a couple are excellent, and one, his Window of Opportunity peek, I think is fantastic. I always keep a few of the specially folded business cards with me to do it and have, in fact, expanded his original presentation. While it's a tad more complicated than Acidus Novus, the Corinda peek, or that cool billet opening thing that Richard Osterlind has demonstrated on a couple of his DVDs, a few days of practice idly doing the move with my left hand was more than enough time to get pretty good at it. It's a worker.
I'm fairly sure that the title The Impromtu Mystifier is a tip of the hat to the great Bob Cassidy and his The Impromptu Psychic. While that work may have more routines, I think that this book is the better value for its outstanding advice on mentalism in general--and that great peek.
