On a tiny island off Paradiso, Florida, in 1970, neighbors gather to toast two new arrivals: shy Catherine and her taciturn husband, Dr. Frank Overbrook, who is taking over an old friend's medical practice. It's an intimate welcoming for the newlyweds, who have abandoned city life for swaying palms and an ocean breeze. But the morning after is anything but peaceful when Frank is found dead on the beach.
Detective Quentin Jones has his eyes on the island's residents and the welcome party's guest list. There's the retiring doctor and host, as well as his nurse. Volatile marrieds Miriam and her husband, David, constantly at each other's throats. The Carters, a strangely antisocial young couple. And Sylvie, a blind sculptor to whom Quentin lost his heart years ago.
