The busy summer tourist season is winding down in Busman's Harbor, Maine, but Julia Snowden senses trouble simmering for the Snowden Family Clambake Company. Shifty David Thwing—the 'Mussel King' of upscale seafood restaurants—is sniffing around town for a new location. But serving iffy clams turns out to be the least of his troubles . . .



When Thwing is found sleeping with the fishes beneath a local lobsterman's boat, the police quickly finger Julia's brother-in-law Sonny as the one who cooked up the crime. Sure, everyone knows Sonny despised the Mussel King . . . but Julia believes he's innocent. Proving it won't be easy, though. It seems there's a lot more than murder on the menu, and Julia needs to act fast . . .
