Campbell admits to kerb crawling but claims to have met Kyle in the arcade by chance and sent him home whilst the dead boy is named as Andre Petri, who died of a heroin overdose and lived near the Heaths. His sister tells Annie that she was amazed how flush he was and it turns out that the arcade was the recruiting ground for under-age drug dealers. Banks suspects the leader is Chivers, a cab driver with previous convictions, who has disappeared with a female accomplice but Helen believes that Katy is not so innocent and is involved with Chivers to get Paul to pay a ransom which he will share with her. Annie shadows Paul as he delivers the money but loses him. Eventually Banks catches up with Chivers and finds that things are not as they first appeared to be.
