About This Book

Horrible Harry knows he's the world's second-best detective (second only to Sherlock Holmes, of course), but the rest of the kids in Room 3B aren't as sure. So he's determined to prove himself by solving the latest mystery at South School: a cafeteria contest has just begun, and Harry wants to figure out how to win it. He knows Mrs. Funderburke, the cafeteria lady, is using a special mathematical code—the Fibonacci sequence—to decide each day's winners, but can he crack the code before Mary tattles on him? Or will Harry's private-eye days come to a horrible end?
