Rosie does the shopping for Miss Edgar. One morning she finds the old woman tied to a chair when she comes to deliver the groceries. Miss Edgar says the assailant posed as a representative from the Council and drove a grey van. It may have been the same van that forced Louise Parry off the road and nearly did the same to David in the brown lorry. David sees to the needs of Miss Parry getting her to the Aidensfield Arms and has Bernie pick up her car. She also asks him to deliver a letter to Dr. Trent's husband Matthew personally. He soon becomes their secret messenger. Meanwhile more victims of the man in the grey van are discovered. PC Walker believes he has information vital to the case, but when Sergeant Nokes refuses to listen to him he does a little investigating of his own among his father's old friends. There is a new constable at the Ashfordly police station. His name is Geoff Younger and this is his very first posting.
