Twelve-year-old Howard Wallace lives by his list of rules of private investigation. He knows more than anyone how to work with what hes got: a bathrobe for a trench coat, a makeshift office behind the school equipment shed, and not much elseleast of all, friends. So when a hot case of blackmail lands on his desk, hes ready to take it on himself . . . until the new kid, Ivy Mason, convinces him to take her on as a junior partner. As they banter through stakeouts and narrow down their list of suspects, Howard starts to wonder if having Ivy as a sidekick and a friend is such a bad thing after all.
