Get mentally fit by exercising your brain on these incredible thinking puzzles! Tricky and challenging, they demand a flexible thought-process and an ability to see beyond the obvious. Are you up to the task? For example: While in his local pub, J.P. comes back from the rest room and sees someone stealing his wallet. Instead of confronting the thief, J.P. just stands there and watches him spend the cash. Can you explain this passive response? (Answer: J.P is a counterfeiter who wanted the wallet snatched; he could then check and see if the money could pass as genuine.) Try to figure this one out: Jim develops an elaborate plan to escape from prison. He succeeds, and actually phones the prison guards to tell them where he is. But they don't bring him back to prison! Why? (Jim wasn't a convict, but someone hired by authorities to test their security system.) Yet another treacherously difficult puzzle deals with a "wonder woman" who can move a two-ton piece of equipment with no help (she's an astronaut in a ship with zero gravity, where objects are weightless). If you're having trouble, clue pages will help you on your way! Sterling 96 pages, 100 b/w illus., 5 3/8 x 8 1/4.
