A skeletal body is unearthed in a wooded area of Peterborough, Cambridgeshire. DI James Bliss, together with DC Penny Chandler, investigate the case and discover that the young, female victim had been relocated from its original burial site. A witness is convinced that a young female was struck by a vehicle back in the summer of 1990, and that police attended the scene. However, no record exists of either the accident or the reported victim. As the case develops, two retired police officers are murdered. The two are linked with others who were on duty at the time a road accident was reported. As Bliss and Chandler delve deeper into the investigation, they start to question whether senior officers may have been involved in the murder of the young women who was buried in the woods. As each link in the chain is put under duress, so is Bliss who clashes with superiors and the media. When his team receives targeted warnings, Bliss will need to decide whether to drop the case or to pursue those responsible. Will Bliss walk away in order to keep his career intact or will he fight no matter what the cost? And is it possible the killer is much closer than they imagined?
