Angie's older sister is a police officer, working hard to solve two crimes. First, a gang of teenagers is robbing homes in the area and there's also a ring of counterfeiters at work. Angie's goal is to solve one or both cases so her sister can get promoted to sergeant. She and her friend Jess patrol the neighborhood on the lookout for suspicious activity. They get more than they bargained for.
Sobol, author of the wildly popular Encyclopedia Brown books, tries his hand with a female heroine and a mystery that's longer than a chapter. He does marginally well with this venture, although young children reading this book might get in quite a bit more trouble than Angie does if they try to emulate her. ( )

This is a cute book about Angie, an amateur detective, written by the author of Encyclopedia Brown. I have fond memories of this book- first time I ever saw my name on a book. ( )
