The artist Joe Vaughan has rented a cottage from Lord Ashfordly to do some painting. He has had a bit of a clash with members of the local rugby club and they do what they can to annoy him. A Liverpool gangster, Boyd, is also interested in him and he has sent two goons to do the dirty job. His benefactor Rod Dundas organizes an exhibition at the cottage, but the night after the opening the cottage burns and all Vaughan's paintings are destroyed. Well not all of them, since one of them is missing. Greengrass gets a grant from the council for his new "romantic boarding house" and can soon greet his first guests. His old friend Betty persuades him to buy a share of the race horse Alnwick Flyer, which must be sold for tax reasons. There is something about Gina's boyfriend Andy that Oscar Blaketon does not like and he starts to follow Andy around like a shadow.

Barbara Simner suspects that her husband Ken is trying to kill her because of several so-called mishaps. She refuses to call the police, but they get involved when she is run down by a runaway tractor. Oscar Blaketon wants the "Best Kept Village" award to go to Aidensfield. A hindrance to this goal is a number of molehills, but Vernon Scripps has an all-purpose pesticide powder which should do the trick. And a potent stuff it is. David passes out while using it and Dr. Merrick suspects it to be very poisonous. The smell of it is surely strong enough to scare everybody away. Even the moles. Gina's friend Diane moves into the Aidensfield Arms to help her during the final stages of her pregnancy. Diane quickly sets her sights on PC Crane. Meanwhile Phil Bellamy is more preoccupied with finding a best man for his wedding to Gina than his police work.
