Plot
It is Logan McRae's first week back after being on sick leave for a year; courtesy of Angus Robertson (The Mastrick Monster) who carved him up with a knife. Someone is kidnapping children, murdering them and mutilating them afterwards. The local paper screams about police incompetence and is gunning for McRae's boss, Detective Inspector David Insch. McRae discovers that someone is leaking the stories to a journalist, Colin Miller, who inadvertently disrupts Grampian Polices' plans to apprehend the killer by revealing their plan to wait out in a secluded location which the killer thinks is safe.

McRae discovers that Miller's source is none other than his ex-girlfriend, Isobel McAlister, the police pathologist, who is now living with Miller and tells him about her day to unwind.

Meanwhile, the local council worker who removes all the dead animals from the roads (affectionately called "Roadkill") is found to have a dead girl in his tip and another dead girl is discovered on the local rubbish dump.
