This is a very silly, funny book about a pair of twins who are the children of crooks. Their parents are raising them to be crooks, but Billy and Jillian want to be good, and have to be sneaky to do so. This story involves the theft of a naughty monkey, crazy disguises, and a lot of smelly trouble at the zoo. The writing is clever and readers will find the dialogue funny. Beginning readers will really enjoy this chapter book, which comes with some activities, jokes and a song at the end. December 2014 review by Carol Schramm.
