 Claude Greengrass is the new lollipop man outside the village school, and PC Rowan gets a complaint from Walter Pettigrew that he suddenly and without warning jumped out onto the street just in front of Pettigrew s car. But Greengrass claims that it was Pettigrew who nearly caused the accident and he is backed up by the new school teacher Jo Weston. Jo Weston is concerned about one of her students, Lizzy McGowan, who is late almost every day. Lizzy s mother lives with her boyfriend Derek Ramsey, who is sent to prison for attacking PCs Rowan, Bellamy and Ventress in a fight at the Aidensfield Arms, but he escapes on the way to the prison. And with good reason too, because the next morning Dorothy McGowan is attacked and badly injured in her home. PC Rowan thinks a mysterious man, who showed up in court, has something to do with it.
