Guy Foxton publishes and sells guide books. Unfortunately one of his guided tours crosses the private lands of Les Parnaby. When the police cannot do anything Parnaby decides to take care of the matter himself. It is not the first time Foxton has had a dispute about the right-of-way and PC Bradley kindly suggests that he removes the route from his guide and does not use it anymore, but Foxton is not forthcoming at all. David's and Vernon Scripps' lorry breaks down and PC Ventress gives Vernon a lift back to Aidensfield. On the way Vernon Scripps hits his head when Ventress has to avoid a sheep on the road. That bump changes his personality and makes him a kind, loving person. He even pays all his debts and gives David a two week holiday on his birthday.
