Lateral Thinking Puzzlers

Logic is not enough! To unravel a lateral puzzle, you have to train your brain to think differently. Ranging from (relatively) easy to fiendishly hard, these classic conundrums - almost 100 of them - require mental agility. Can you figure out these problems from only the vaguest details and yes-or-no questions? It's challenging, imaginative fun. This is a revised edition with entirely new illustrations.
