Detective Joe Cashin, recovering from injury in his coastal hometown of Port Monro, investigates the beating death of wealthy local benefactor Charles Bourgoyne. Cashin keeps digging and finds that the real motive lies in Bourgoyne's own buried past as an abuser of vulnerable boys.
Once a piece of physical evidence fits a suspect the community is already primed to blame, the investigation stops looking for disconfirming facts. Stolen property proves only possession, not the crime. But when possession lines up with existing prejudice, it is treated as a confession, and institutions become invested in the story being true.
A wealthy, philanthropic victim gets his reputation protected by everyone who benefited from him: family, police, developers and local institutions. Asking who gains from the victim's good name reveals what an investigation is being steered away from.
A detective who comes home, damaged and sidelined from the central institution, holds a double position. He has local knowledge and trust that outside police lack. His marginal standing also frees him from the career pressures and loyalties, such as the union and the brass, that push colleagues toward the official story. Being wounded and peripheral becomes the condition that makes seeing clearly possible.
