It's particularly quiet on Martha's Vineyard this summer, since a shadowy figure called "the Silencer" began his covert campaign of destruction -- disabling the audio systems in the homes and vehicles of selfish, music-blasting islanders. A respite from the unwanted noise suits fishing enthusiast, former cop, and sometime investigator J.W. Jackson just fine -- until a gargantuan new Chappaquiddick mansion is vandalized and a night watchman is thrown to his death off a nearby cliff. Hired by the aristocratic mother of the most likely suspect to help prove her son's innocence, J.W. starts to explore some mysterious connections linking the Vineyard's most prominent families. But digging up the dirty secrets of the island elite may only inflame a murderer who's not done killing -- and hasten J.W.'s own journey to the graveyard.
