All the characters in these puzzles make clear statements about themselves and others, but it is not clear whether or not they are telling the truth. Anyone could be lying. As always, a good logical puzzle is one which it is possible to unravel by thinking logically. The problem is to decide which person to believe. Altogether there are 85 original puzzles in this book ranging in standard from fairly easy to quite demanding. There are also some curious paradoxical pictures which raise questions which are rather hard either to answer or to ignore. Answers are provided, and also some excellent suggestions for techniques you might use to solve the problems. Not just a puzzle book - it's a "how-to" book too!
