Ejiofor plays Jonah Gabriel, a detective suffering amnesia after being shot in a previous operation. Unsure of his own moral compass, Gabriel has to follow an increasingly complicated line of investigation, all the while wondering whether he can trust anyone, not least, himself.
Also investigating the death is Joseph Bede (Eccleston), an associate of Wratten’s, who has built up a legitimate fruit and flower business during Harvey’s time in prison.
Now, driven by a profound personal tragedy, Joseph finds himself planning one last deal: a massive drugs operation that he is desperate to see through, so he can retire and step out of the business for ever.
Thursdays on BBC Two from May 5th
