London Kills

In exchange for turning a blind eye, Adrian gives Rob the name of someone who knows where Sarah is, but that person turns up dead. Now believing that Sarah may still be alive, David and his team race to her find her.

DC Rob Brady and Trainee DC Billie Fitzgerald respond to a gruesome scene: a man found stabbed multiple times and left hanging from a tree. DS Vivienne Cole expects to lead the investigation but is shocked when DI David Bradford takes over, as he has been on leave since the disappearance of his wife.
