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 1

When a headless and handless body is found in a North London scrapyard, the team led by Sunny are called to investigate. They suspect the body was illegally dumped, perhaps transported inside a white goods item. This is confirmed when pathologist Leanne Balcombe finds that the dismembered corpse had been frozen.   

The body is identified as one Matthew Walsh who went missing 30 years before and we start to meet four people who may be connected with his disappearance.  In the Peak District, therapist Fiona Grayson, in Cambridge, high flying career woman Elizabeth Baildon, in Rochester, businessman Dean Barton and in Southall, expectant father Ram Sidhu. Boulting and Lingley find out that Walsh was last seen on 30th March 1990 and start to try and track down his next of kin.

Meanwhile, Cassie’s plans to retire are thwarted and she is forced to return to work just as her father Martin’s early dementia appears to be getting worse.

The team discover that the body had been transported in a freezer purchased by a recently deceased man, Robert Fogerty who had a police record for a traffic offence the same night that the victim disappeared and that there were four other people in the car with him.
