There has been a break-in at Sanger's Telephone Services. CID suspects a gang, who is behind other break-ins in the area and wants no help from the Ashfordly police, but sergeant Blaketon thinks it is an inside job and pushes his constables hard to solve the case and prove to CID that they are capable of handling their own patch. Greengrass is supplying Tony Mowbray, who works at Sanger's, with pheasants, hares and other kinds of game, but because Mowbray is under suspicion they cannot shift it.

Bill Dyer asks PC Bradley to take a closer look at Giles Sutton whom he suspects of rigging the sheep market. Sutton senses what is going to happen and offers Jackie his legal account. He even pays for their meal one night he "spots" Mike and Jackie having dinner at a restaurant. Mike gets angry when he finds out, but Jackie insists Sutton only did it as a gesture to her totally failing to recognize the consequences it may have on her husband. Sutton even leaves a large amount of money in Mike's jacket, and although Mike returns the money he is suspended for taking bribes. But even worse is to come in Mike's and Jackie's private life.

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.

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.

Is it Gorman or the Leeds gangster Jimmy Faye looking for Alec Fletcher, whom the police is hiding because he wants to testify against him? Lord Ashfordly is looking for a new game keeper. Oscar Blaketon and Gina suggest to Aunt Peggy in fun that she applies for the job and she thinks it is an excellent idea. Lord Ashfordly does not! PC Mason's past catches up with him when his old girl friend Doreen turns up in Aidensfield looking for work. After a broken marriage she is not uninterested in reviving the relationship.
