Judy Moody is in a mood—a sleuthing, Nancy Drew kind of mood. So what’s a WBMS (world’s best mystery solver) to do? Go find a mystery, that’s what! And she doesn’t have to snoop for long: when Mr. Chips, a beloved crime-dog-in-training, goes missing, Judy Drewdy and her chums, agents Dills Pickle (Frank), Spuds Houdini (Rocky), and James Madagascar (Stink) find themselves smack-dab in the middle of a real life, scare-your-pants-off whodunit. Was Mr. Chips stolen by dirty dognappers? And why are chocolate-chip cookies disappearing all over town? Watch out for red herrings—along with clever references to classic Nancy Drew mysteries—as Eagle Eye Moody and company are hot on the case!
