Unforgotten (series 4)

Series synopsis: 

BAFTA nominated actors Nicola Walker (Last Tango In Halifax, The Split) and Sanjeev Bhaskar (Yesterday, Goodness Gracious Me) reprise their roles as DCI Cassie Stuart and DI Sunny Khan in the highly-anticipated fourth series of critically acclaimed drama, Unforgotten.

Produced by independent production company Mainstreet Pictures (Gold Digger, Age Before Beauty) in partnership with Masterpiece, and devised and written by acclaimed screenwriter Chris Lang (Innocent, Dark Heart), the new six-part series charts a fresh investigation into another emotionally-charged cold case murder. 

The main cast is joined by Sheila Hancock (New Tricks, Delicious), Susan Lynch (Killing Eve, Apple Tree Yard), Phaldut Sharma (Hanna, EastEnders), Liz White (Life On Mars, Ackley Bridge), Andy Nyman (Wanderlust, Peaky Blinders), Clare Calbraith (Baptiste, Little Boy Blue) and Lucy Speed (Marcella, National Treasure), along with returning actors Peter Egan (Downton Abbey, Hold The Sunset), Alastair Mackenzie (Deep Water, Cold Feet), Carolina Main (Blood, Grantchester), Lewis Reeves (Uncle, Inspector George Gently) and Jordan Long (Prime Suspect 1973, SS-GB).

The fourth series opens with the discovery of a dismembered body in a scrap metal yard, which the team believe has been stored in a domestic freezer for thirty years. A unique Millwall Football Club tattoo leads to the victim being identified as Matthew Walsh, a young man in his mid-twenties who went missing in March 1990.

Episode 2

Cassie and Sunny continue to investigate Fogerty’s driving offence.

Without the rest of the victim’s body, the team are unable to establish cause of death and are under pressure to progress the investigation.  Without hard evidence, Andrews is reluctant to believe that the police probationers were involved. 

Boulting has tracked down Walsh’s next of kin, his estranged son Jerome.  Cassie pays him a visit, but he reveals he has never met his father and the only contact he has is his Uncle Clive.   Meanwhile Collier has drawn a blank with the search for the rest of Walsh’s body but Sunny has had a breakthrough and identified the names of the four passengers in the car.

Dean Barton makes a mysterious trip to France and Liz Baildon is up for a promotion to the top job in the East Anglian police force.  Ram is experiencing problems at work as he faces an allegation of inappropriate behaviour while Liz finalises the purchase of her new therapy clinic.

Jerome’s DNA confirms that Matthew Walsh is definitely the victim and Cassie instructs it to be put out on the evening news.
