The main cast will be joined by Sheila Hancock, Susan Lynch, Phaldut Sharma, Liz White, Andy Nyman, Clare Calbraith and Lucy Speed, along with returning actors Peter Egan, Alastair Mackenzie, Carolina Main, Lewis Reeves and Jordan Long.
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.
Series 4 will air in 2021.
