In Broken Harbour, a ghost estate outside Dublin, two children and their father are dead. The mother is on her way to intensive care. Scorcher Kennedy is given the case because he is the Murder squad's star detective. At first he and his rookie partner, Richie, think this is a simple one. But there are too many inexplicable details and the evidence is pointing in two directions at once. Scorcher's personal life is tugging for his attention. Seeing the case on the news has sent his sister Dina off the rails again, and she's resurrecting something that Scorcher thought he had tightly under control: what happened to their family at Broken Harbour, back when they were children.
