When a man dies falling from a bridge Joe discovers the deceased and his girlfriend were implicated in a baby's disappearance three years previously. Foul play is suspected when the man's post-mortem reveals injuries consistent with a recent fight, and deeper delving suggests someone still believes the couple were responsible for the missing child. Elsewhere, Peggy's new look and odd behaviour causes a stir

A body is found buried on the Northumberland moors which could be a missing teenager from the nearby rural community of Brindale. The girl had disappeared six weeks previously, and Vera has to break the news to her devastated family. However, the realisation that she died so close to home rather than at a music festival as originally thought creates tension among her neighbours, who are soon suspecting each other of murder. The detective delves into the vulnerable young woman's isolated existence to identify her killer

The discovery of a 2,000-year-old body provides fresh evidence in a five-year-old unsolved missing persons case, so Morse and Thursday take up the investigation, discovering a possible link to a local pagan ritual to celebrate the harvest. The investigation leads them to a nuclear power station, where they face a conspiracy of silence concerning an experimental new reactor and a potential disaster that could devastate Oxford. Guest starring Sheila Hancock, widow of original Inspector Morse star John Thaw

Part one of two. A recently released convicted murderer returns to London in a bid to prove his innocence - only to be shot in the arm by the aggrieved father of his alleged victim. But even he eventually begins to doubt the man's guilt, and when Walker and Connor investigate, they unearth a tale of buried secrets, injustice and revenge. David Hayman and Victoria Smurfit star, with Maurice Roeves and Johnny Harris
