The Q&A Predates every other form of mentalism routine by thousands of years. In it, you will find the origins of what today we think of as mind reading, psychometry and prediction.
Between the covers of this book, you'll find not only psychological techniques and philosophies for what constitutes a believable performance of the Q&A but also multiple physical techniques developed through trial and error over a period of thirty years.
Welcome to the world of multidimensional Q&A.
