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.

The theft happened after closing hours so the thief can only be another one of the guests or a member of staff. Geoff Younger is on the lookout for a car of his own and it must be something with a lot of oomph because he is tired of being overtaken all the time. Aunt Peggy knows somebody in the business and promises to help him.
