When a local potato chip tycoon invites area kids to an all-day puzzle hunt, Winston Breen is psyched. But it turns out the day is not all fun and games. Their teacher is being overly competitive, the puzzles are hard (even for Winston), and someone in the contest is playing dirty in order to win the fifty-thousand-dollar grand prize! Trying to stop the mystery cheater before it’s too late takes an already tough challenge to a whole new level. . . .

Perfect for fans of The Westing Game, exciting mysteries, and, of course, puzzles!
