This three-part sequel to the 1999 drama The Murder of Stephen Lawrence, which depicted Doreen and Neville Lawrence’s struggle to prove that their son was murdered by a gang of racists in 1993, picks up in 2006, six years on from the groundbreaking Stephen Lawrence inquiry into the Met Police, and yet without any further progress in the case. DCI Clive Driscoll (Steve Coogan) takes on the cold case in tonight’s opening episode, convinced that he can bring those responsible for the murder to justice. Ammar Kalia
