Claudeline Feng LeBernardin learns what it really means to be bad in this “sharp, fun, and optimistic” (Kirkus Reviews) Edgar Award–nominated mystery reminiscent of Harriet the Spy.

Claudeline Feng LeBernardin is very good at being bad. Her Grandpa Si was a real-life gangster, and Claude always thought she’d take over the family business when he was gone. Instead, Claude’s dad is in charge—and she’s sure he’s running things into the ground. She wants to step in, but her parents are keeping secrets and her partner in crime, Fingerless Brett, is suddenly on the straight and narrow.

Then, when a very strange character by the name of Alma Lingonberry shows up in the neighborhood, Claude gets closer to the crime life than ever. Before long, she’s swept up in a maddening mystery that’s got her wondering: What does it really mean to be bad?
