These Dark Things — Jan Merete Weiss

When a beautiful college student is found murdered in the catacombs beneath a monastary, Captain Natalia Monte of the Carabinieri is assigned to investigate. Could the killer be a professor the student had been sleeping with? A blind monk who loved her? Or perhaps a member of the brutal Napali criminal organization, the Camorra? As Natalia pursues her investigation, the crime families of Naples go to war over garbage-hauling contracts; and all across the city heaps of trash pile up, uncollected. When one of Natalia's childhood friends is caught up in the violence, her loyalties are tested, and each move she makes threatens her own life and the lives of those she loves.
