Henry Dudeney (1847–1930) had a talent for finding solutions to problems that seemed unsolvable. This unique book presents 110 of his puzzles — not as individual problems but as incidents in connected stories. The first 31 problems are posed by the pilgrims in Chaucer's Canterbury Tales; additional puzzles are presented using different characters in other venues. Many require only the ability to exercise logical or visual skills; others offer a stimulating challenge to the mathematically advanced. In all cases, solutions are provided at the end.
