The bungled bike burglaries

Seventh grader Gabby St. Claire is determined to bring a bike burgler to justice -- and not just because mean girl Donabell Bulluck is strong-arming her into it. But each new clue brings its own set of trouble. As if that's not enough to handle, Gabby finds evidence of a decades-old murder within the contents of the time capsule, but no one seems to take her seriously.
