Rachel discovers Nick has been brutally assaulted - and she is top of the list of suspects. But even worse, she has no recollection of the previous night after a drunken hen party, and struggles to convince herself she did not do it. Janet thinks she has made her peace with Andy, until he gives her some misinformation that results in Gill missing an appointment with the coroner - so the DCI, tired of their games, announces one of them will have to go. A man's accidental death turns into a murder investigation when his daughters reveal their mother often talked of killing him

Janet comes face to face with the man who left her fighting for life just months earlier - serial killer Geoff Hastings, who has vowed to finally reveal the full extent of his crimes. Rachel and the rest of the team investigate the racially motivated murder of a taxi driver. On the personal front, Andy refuses to take no for an answer, so Janet threatens to report him to the DCI.

In the first of a two-part story, the badly burned body of a disabled man turns up in a remote part of Manchester and a few days later another corpse is discovered. The detectives start to realise the victims were not just murdered, but tortured too. They make an arrest, but it becomes clear their investigation has just scratched the surface. Meanwhile, Janet throws her husband out and Rachel's estranged brother turns up on her doorstep. With Lisa Riley and Pippa Haywood.

It's Murray and Bailey this week, as Rachel travels to Bristol with the DCI, who is advising on a rape and murder which bears similarities to a case she worked on 13 years previously. Back then she helped catch the perpetrator, who killed four women, but naturally he is protesting his innocence. At home, Rachel discovers her brother Dom has been prostituting himself in her flat - and just to top things off, she learns the charges against her ex-boyfriend Nick are being dropped.

The syndicate deals with a shooting, and discovers that the victim has been sexually mutilated. Andy seems determined to freeze Janet out of the investigation. Sean tries to engineer a reconciliation between Rachel and her mother, and Rachel warms to the idea of marriage.

The duo look into the murder of an eight-year-old boy, coming up against a pedophile who cruelly deceives his victim's family. Dom's HIV test comes back negative, so he sets out to celebrate - only to endanger his own life and jeopardize Rachel's sergeant's exam in the process. Janet tells Andy she is having second thoughts about their brief liaison, but he finds her decision hard to accept.

Rachel discovers Dom drinking a can of beer with Sean. She takes the can away from him and warns Sean that Dom has a drink problem. Sean wants Rachel to meet his son from his defunct marriage, if she’s going to be his ‘other mummy’. Sean continues to act like they’re getting married, whilst Rachel insists they’re not. Andy wants Janet to join him for a drink as he wants to talk but she turns down his offer. Gill is forced to leave a briefing on a mercy dash for Sammy because Dave’s drunk. Gill wants Janet's help get Dave round to his mother’s. A woman with a green face and head, and dressed in a sexy policewoman’s outfit, is discovered dead in a field at Dob Cross. Gill thinks that the killer is a lover.

Part two of two. Despite arresting four people, the detectives face a wall of silence in their investigation into the grisly murders - but they eventually make a breakthrough, which doesn't quite give them the answers they were expecting. On the domestic front, Rachel wakes up in bed with charismatic colleague Sean - a mistake she is keen never to repeat - and Janet wants to keep her newly single status a secret. So the last thing she needs is daughter Taisie telling Andy about her dad moving out.
