Karen Pirie is the latest series from World Productions, who were behind hits such as Line of Duty and Bodyguard. Based on Val McDermid's novel The Distant Echo, the first episode sees DS Karen Pirie tasked with reopening an historic murder investigation that has been the subject of a provocative true crime podcast.
When teenager Rosie Duff was found brutally murdered in the Scottish university town of St Andrews in 1996, suspicion fell on the three drunken students who were discovered at the scene of the crime, claiming to have found her body.
