Trust, Part III (3)

Part Three - In Another Life: Harker tells Cullen that he knows Leroy didn't kill DS Hanbury, but CID use the charge as leverage to convince Leroy to help them catch Resenbrink. Rickman attends a possibly racially motivated attack on Didi Marr, the boy who was found with heroin on the Bronte Estate. His attacker is Nicky Gable, and the racial element of the case becomes unlikely when it is revealed that Gable is in mourning for his mixed-race brother. Harker arranges with Leroy to escape, and offers to clear him of the murder charge on the condition that he ends his relationship with Rickman. With Leroy's help, Cullen and Pennington arrest Resenbrink, but when he is freed on bail, disaster strikes.
