Only the Dead — Ben Sanders

When a failed witness protection operation ends in multiple homicides, evidence suggests the crime is linked to a series of violent robberies in Auckland City. For Detective Sergeant Sean Devereaux, solving the case is proving next to impossible. His own superiors in the police department are refusing to cooperate with his investigation. After Devereaux shoots a suspect in a botched surveillance job, he is forced to start providing the answers rather than demanding them. With his career on the line and old demons threatening to consume his very sanity, Devereaux is running out of time as he succumbs to a nightmare world of extreme brutality, where bad and desperate men stalk both sides of the legal divide.
