This is a great collection of puzzles from the Master Of It All. However, the book is exactly what is says it is: It is a collection of Martin Gardner's puzzles previously published in Scientific America. That means if you have followed Gardner's column over the years, you will have seen many of these puzzles already. And precisely because they're the "best," chances are you still remember them. Of course my favorite (a monk leaves his monastery and goes up the mountain...) is in there, as are a number of other favorites.
