Charlie Collier is back solving mysteries out of his parents' garage, and this one's a doozey!

Actually, there may be more than just one mystery out there to solve. There's Charlie's friend Sherman's brother, who is missing. And then there's a series of robberies in town involving masked teenagers. Could they be related?  Charlie has to get himself in a heap of trouble--like getting thrown in juvie!--to figure out what's going on.

Filled with action, adventure, humor and brain teasers, this is perfect for an older elementary school or young junior high school mystery fan.
