The Frog Who Croaked

Gr 3–6—Followers of Krosoczka's "Lunch Lady" series (Knopf) will be delighted to discover the author's foray into the realm of chapter books. This CSI-style mystery revolves around two platypus police officers. When rookie detective Rick Zengo is teamed up with veteran Corey O'Malley, the relationship is off to a rocky start. The two are assigned to investigate a missing local teacher and an illegal fish trade, and all signs point to the docks. Early clues indicate Frank Pandini, Jr.'s businesses, but Pandini is supposedly an up-and-up businessman (panda) trying to improve his family's reputation. Exuberant Zengo wants to make a name for himself on the Platypus Police Squad and not follow in his legendary grandfather's shadow, but his inexperience threatens the investigation. Details such as the cops using boomerangs to capture the bad guys and the local hangout serving root-beer floats make the mystery delicious fun. Burgeoning with detective clichés, affable characters, and lots of cartoon art, the book will be popular with Krosoczka's fans and amateur sleuths not ready for a darker thriller.—Michele Shaw, Quail Run Elementary School, San Ramon, CA
