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 - and clever references to classic Nancy Drew mysteries - as Eagle Eye Moody and company are hot on the case!
