If you want an insane amount of brain gymnastics, this is it

I took one look at the puzzles in this book and was scared to death! :) If you want an insane amount of brain gymnastics, this is the book for you. Features code-breaking puzzles, memory tests, word games, and the rest of the normal MENSA stuff. In this book you pretend you're a detective or spy.
