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.

Tommy Rawson breeds sheep dogs and he the favourite to win this year's trials as it has done two years previously with his dog Jess. His nearest competitor is George Harding, who is a close friend of Lord Ashfordly and used to have things his own way. When he cannot win fair and square he will stop at nothing to discredit Rawson and have his dog disqualified. Harding's wife Maureen is hardly any better. She has got severe anxiety and expects Dr. Summerbee to prescribe her pills for it at will. Vernon Scripps is providing lavatory facilities for the trials and he soon discovers that it involves more than just putting up a tent or two. Good news for Sergeant Merton. His diabetes will have no bearing on his position as sergeant at the Ashfordly police station as long as he gets his medication.
