Joyce Jowett has just lost her husband when a stranger called Nigel Wheeler turns up in Aidensfield asking for him. He is a financial advisor and while he is in the area he might as well visit other potential customers. One of them is Jo Weston and PC Rowan decides to take a closer look at him. George Ward and other villagers have received malicious letters. The only lead is that they are all written on the same typewriter.

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. Jo Weston is concerned about Dennis Cross, who is absent from school almost every day because he has to take care of his ill mother. When Nick and Jo check on her they find her dead at the bottom of the stairs, but Dennis has made himself scarce.

Nathaniel Clegghorn believes his farm is haunted and has sent for paranormal investigators to authenticate it so that he can arrange guided tours for a fee. Greengrass thinks that is a brilliant idea and produces a couple of "ghostly manifestations" himself. An old acquaintance of Oscar Blaketon and the police, Jimmy Turpin, is back in Aidensfield and Blaketon warns sergeant Rowan that he might be up to something. He is, but gets his daughter Mitzi and her husband Johnny Wyler to do the dirty work. Nick Rowan has got a new job with the Royal Mounted Police and he and his family prepare to leave for Canada. PC Bradley takes over his position as village bobby in Aidensfield. Neil Bolton is tired of working at the hospital and has a look at Kate Rowan's old practice in Aidensfield.

Oscar Blaketon gets into trouble when two young criminals steal his car and run away from an accident they have caused, because he will not account for his whereabouts at the time of the accident and did not report the car stolen. Meanwhile the two criminals, Joey Sharp and Frank Collins, supplies drugs to the schoolgirl Lizzie Tyler and her friend Babs. Greengrass overhears how PC Bradley talks to a friend about buying classic motorcycles and spots an opportunity to earn a quit or two. He even knows where hen can get his hands on some if he can get Bernie Scripps to assemble them.

There has been an intruder at the Moorside Lodge mother-and-baby home, but he was scared off by Paula, who had just been looking after her baby, and nothing was taken. Allan and Hazel Mansfield have a lot of problems with their baby Peter, who needs a lot of attention. Peter is taken from his pram while Mrs. Mansfield is doing an errand at the post office. He was adopted from Moorside Lodge, and sergeant Craddock believes that his natural mother may have taken him. But time is running short, because Peter is ill and may have trouble breathing without his medicine. Greengrass has found a new way to make money: laying out driveways and such. He is helped by the mechanical wiz Gary Clarkson, who has fixed his lorry.

There has been a series of break-ins at the homes of recently deceased persons and the clues lead to Cyril Fuller an old friend of Claude Greengrass. Greengrass is convinced that his friend is innocent and is persuaded to do something he would have thought he would never do - help the police! Blaketon has bought the Aidensfield Arms from Lord Ashfordly, and soon he drives both Gina and Aunt Mary crazy with all his demands. Maggie Bolton is enjoying motherhood so much she decides to quit her nursing job. But a serious outbreak of the flu may make her reconsider. Blaketon and Greengrass are both sure they will not catch the illness because they have ways to avoid it. Yeah and pigs might...

Gary Tyler visits his girlfriend Lyn, who works as a maid at Ashfordly Hall. When he sneaks out under the cover of darkness he is shot at and wounded by Lord Ashfordly's state manager Reed. Or so they say, but PC Bradley is not quite sure. Things do not look good for Tyler, because he has a suspended sentence, but he does not want to involve Lyn although she can clear his name. Greengrass helps a stranger, who has run out of petrol. The stranger, Bill Austin, works at a local newspaper and to show his gratitude he offers Greengrass a weekly column in the paper. The old scoundrel does not hesitate to make the best of it for himself and make full use of the situation.
