When murder turns out to be the special of the day at her friend's seafood restaurant, bicycle shop owner Mackenzie "Mac" Almeida and her fellow book club sleuths have to net a killer . . . From clam chowdahs to oysters on the half-shell, Tulia Peters' Lobstah Shack offers locals and tourists in Westham, Massachusetts, some of Cape Cod's most amazing cuisine. But when the body of Annette DiCicero is discovered in the kitchen's walk-in freezer-with a custom-made claw-handled lobster pick lodged in her neck-spoiled appetites are the least of Tulia's worries. After a heated public argument with Annette, Tulia is a person of interest in the police's homicide investigation. To clear Tulia's name, Mac and the Cozy Capers Book Group snoop into Annette's personal life. Between her temperamental husband, his shady business partner, and two women tied to Annette's past life as "Miss New Bedford", there are now several suspects and multiple motives. And they're getting crabby about Mac intruding on their affairs . . .
