Karen Pirie plot
Karen is a young woman with a smooth talk and a sharp mind. After her promotion to Police Scotland's Historic Cases Unit, she must reopen the investigation into an unsolved murder. A young barmaid had been stabbed to death in 1995 and the three students who found the body were originally suspected. Despite the police investigation, they were never charged at the time. As she conducts her investigation, she will soon realize that the original investigation was full of errors. Those discoveries will bring her into conflict with the same officers who originally worked on the case.
