What will happen in Unforgotten series 4?

The new episodes will see Cassie discover that her plans for retirement from the police force have been thwarted just as her father’s dementia is worsening – she learns she isn’t entitled to her full pension payment unless she completes her 30 years of service.

Cassie is gutted, but decides to return to work and join Sunny who is investigating the case of a headless body found dumped in a north London scrapyard. It’s frozen rock solid, leading to the conclusion that it has been stored in a domestic freezer for decades.

Whose remains will be found in Unforgotten series 4?

The fourth series will kick off with the discovery of Millwall Football Club supporter Matthew Walsh’s dismembered body in a scrap metal yard, but the team believes it had previously been stored in a domestic freezer for 30 years.

Considering he had gone missing in the 1990s and the owner of the freezer is dead, the mystery behind Walsh’s death will be a hard one to unravel.
