A builder demolishing a wall finds the body of nine year old Leo Priestley, a friend of Marcella’s son Edward, abducted three years earlier. After a fruitless interview with convicted paedophile Phil Dawkins investigations lead to ageing, ailing rock drummer Reg Reynolds, who lives in the flat next door to the murder scene. Marcella visits it alone and is attacked. Factory owner Vince Whitman hits the news for exploiting under-age workers whilst divorced Leslie Evans is concerned by her son Adam’s odd behaviour and Marcella freaks out when she sees Edward getting into Jason’s new girl-friend Becky’s car. Somewhere in the city another young victim lies bound and vulnerable.
