The Snowden Family Clambake Company has a beloved reputation in Busman's Harbor, Maine. Almost as famous is the sleuthing ability of proprietor Julia Snowden, which is why an oyster farmer seeks her out when she's in trouble.

When Andie Greatorex is robbed of two buckets of oyster seed worth $35,000, she wonders if somebody's trying to mussel her out of business. Could it be a rival oyster farmer, a steamed former employee, or a snooty summer resident who objects to her unsightly oyster cages floating on the beautiful Damariscotta River? There's also a lobsterman who's worried the farm's expanding lease will encroach on his territory and Andie's ex-partner, who may come to regret their split. Before Julia can make much headway in the investigation, Andie turns up dead, stabbed by a shucking knife. Now it's up to Julia to set a trap for a cold and clammy killer . . .
