A Snitch in the Snob Squad

There are mysterious goings-on at Montrose Middle School. Someone has been snitching money from teachers' desks. Who could it be? Max, whose bad-girl reputation seems to stick to her like slime? Our heroine Jenny's new boyfriend, Kevin, who all of a sudden has money enough to shower Jenny with expensive gifts? Or Ashley, the snotty principal's daughter, who's been acting awfully suspicious lately (so what else is new)? Maybe it's all of them. Or none of them. Whoever the thief is had better take cover because the Snob Squad is on the case.
