Ex-cop Andrew Yancy got fired after assaulting his girlfriend’s husband with a vacuum cleaner attachment. Now he's on “roach patrol” as a restaurant inspector, but he gets his chance at redemption when Sheriff Sonny Summers tells him to take a shark-bitten arm reeled in by a fisherman to Miami. DNA testing identifies the limb as belonging to Nick Stripling, whose boat was wrecked at sea. Stripling’s daughter claims her stepmother murdered her father, and if Yancy can prove it, he can get his old job back. Add a voodoo witch and a deranged monkey, and you have another zany Florida Hiaasen adventure.
