The Vineyard's criminal du jour, "the Silencer," is loved by many and hated by some for his campaign to destroy the audio systems in music-blasting party houses and open-windowed vehicles. Owners of said houses and vehicles feel both fear and hate, while some residents who seek silence silently cheer. J.W. Jackson, former cop and now a part-time investigator, finds it difficult to get too excited about the Silencer's crimes. J.W.'s a classical music man himself, which may explain his reluctance to take the so-called crimes very seriously. The fun stops, however, when someone is killed—a night watchman is thrown over a cliff near a large new Chappaquiddick mansion. Who will be next?
