In Broken Harbour, a ghost estate outside Dublin - half-built, half-inhabited, half-abandoned - 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: Pat Spain was a casualty of the recession, so he killed his children, tried to kill his wife Jenny, and finished off with himself. But there are too many inexplicable details and the evidence is pointing in two directions at once.
