"Great Lateral Thinking Puzzles" by Paul Sloane and Des MacHale is a book of puzzles consisting of strange sounding situations drawn from real life. The puzzles have a logical explanation that readers have to figure out. There are four groups of puzzles: Tempting Puzzles; Intriguing Puzzles; Grisly Puzzles; and Diabolical Puzzles. The easiest puzzles are in the Tempting Puzzles section and the Diabolical section has the most difficult puzzles. The grisly puzzles all feature deaths, accidents, or mutilations. After the puzzle section is the clue section, which contains either hints or yes or no questions for each puzzle. After the clue section is the answer section. There are also two WALLY tests (World Association for Laughter, Learning, and Youth) (one easy and the other more difficult) which are trick questions designed to fool readers.
