A compromised homicide detective must confront his professional and personal risks when a woman is murdered on Nantucket Island in a gripping novel by the author of Cold Island. Detective Tommy Kelly has been exiled to Nantucket as the island’s lone state trooper—punishment for professional misconduct that left him isolated, bitter, and relegated to traffic violations. For a homicide detective, there isn’t much to do in a place others call paradise. Until a young woman is found floating in the harbor in Pocomo. The case forces Tommy to partner again with NPD detective Jo Harris, reopening wounds from their shared past and reminding him of everything he destroyed. Keeping things professional and by the book, they quickly identify the victim—a house cleaner—and close in on their prime suspect. But the investigation takes an unexpected turn. So does Tommy’s judgment when he reignites an affair with a married college acquaintance. As Tommy and Jo follow an unexpected twist in the case, they discover that beneath Nantucket’s pristine beaches and old-money elegance, something dark is festering. And it’s about to surface.
