The retired school teacher Celia Hanson has bought a cottage in Aidensfield. But she does not get along with her neighbour Don Foster, who does nothing but intimidate her on purpose, she claims. It peaks when his tractor rolls into her car after he threatened to drive straight through it. Furthermore rumour has it that Foster has killed his wife, who disappeared suddenly a few years earlier. Frank Jarvis suggests to Greengrass that he lend him a field to dump waste, but Greengrass will not settle for percentages only if he can be in charge himself and he decides to go into business himself. When he and David collect the first load David finds a live grenade, which he likes so much he decides to keep it for himself as a special treasure.

Vernon Scripps has become a more or less permanent chauffeur for the unpopular business man Jim Pinder. Pinder even hires Vernon to haul a boat on a trailer for him. The lorries from Pinder's quarry are a nuisance to a lot of villagers in Aidensfield, but many of them also depend on the quarry to make a living. Things heat up when one of the lorries has braking trouble and almost hits some school children and protesters block the access to the quarry. Somebody has vandalized Lily Barton's boundary wall and two dozen sheep are missing. She is also ill and PC Crane asks Dr. Merrick to have a look at her. But the old lady does not want a doctor thank you very much. And she does not want to move to a home either.

The big day has arrived for Sergeant Merton and Jenny. The day of their wedding. But as it is almost a tradition for police weddings in Aidensfield something puts a spoke in their wheel. A masked robber has assaulted an armoured car and gotten away with thousands of pounds in old, used notes. The modus operandi suggests that the robber is Ronnie "The Dogman" Brown and Merton's old friend DS Kenny Parker is in charge of the investigation. Not surprisingly Brown has made himself scarce when the police come to pick him up. Meanwhile everybody else is occupied with the preparations for the wedding. Vernon Scripps promises to get a freshly caught wild salmon. He counts on catching it himself and to an (instant) expert on fly fishing that should not be any problem, should it? Despite her pregnancy Gina still has second thoughts about marrying Phil Bellamy.

Gina still has second thoughts about marrying Phil Bellamy, because it means she will have to give up the Aidensfield Arms due to an outdated police regulation, and she goes to back Liverpool to think things over. PC Crane is investigating a strange break-in at old William Barraclough's farm. Nothing was taken, but a statuette was left on a table, and a shop owner says he bought it himself. Barraclough also gets a shipment of cement he has not ordered. Is he getting senile or does somebody wish to make it appear so? Vernon Scripps has been summoned for jury service. He grows impatient when everybody else is chosen before him and leaves, because he has other important things to do as well. He has left David with a thorough list of what to do in his absence.
