The Missing Dollar puzzle from Martin Gardner's Aha! Gotcha book series
by Mark Frauenfelder from on (#1A8Q6)
Martin Gardner wrote Aha! Gotcha: Paradoxes to Puzzle and Delight and Aha! Insight in the early 1980s and I love them both. Both books have excellent brain teasers with charming illustrations. They are both out of print, which is criminal, but Amazon has used copies for $0.01 (plus $3.99 s&h).
