Greengrass has a soft job cleaning Lord Ashfordly's lawns for moles. To ensure a lasting employment him and David puts the moles back again at night. One night they are surprised by his lordship's sister Patricia, who is drunk as a skunk. It soon becomes clear that she has a drinking problem, and she is convinced that the law against drunk driving does not apply to nobilities like herself. She also has a soft spot for Steve's father Harry, whom she had a crush on when they were young. When Lord Ashfordly is away hunting for a couple of days Greengrass decides "to put Ashfordly Hall on the map" as he calls it and he organizes a poaching party in his lordship's absence.

Lord Ashfordly's sister Patricia Brewster is visiting her brother to present her new fiancée Ronnie Harper. Sober. While his lordship is giving an engagement party in their honour one of his guests is burgled and another one was the previous night. Lady Patricia asks her fiancée, who has a criminal record, if he knows something about it, and the police have an eye on Harper too. Harper on the other hand has both his eyes set on Gina who is not insusceptible to his charm. Greengrass is harbouring two workmen, Keith and Chas, who do some renovations around the village. Among other things they are refitting Oscar Blaketon's bathroom, and he smells a rat.

Jackie gets a visit from her old friend Caroline. She is surprised to learn that Caroline has a baby. Caroline needs a day off from motherhood and leaves the baby with Jackie and Mike while she goes to York to see some friends. Mike leaves the baby in a pram outside the police house, but when Jackie comes home from an errand the baby is gone. Jackie is not the only one who has a visitor. Lady Patricia visits her brother at Ashfordly Hall together with an old family friend Lord Hal Tadcaster. Well "together" may not be the proper word, because she would rather see him leave than stay. And with good reason since the CID suspects Tadcaster of being a drug dealer and asks the police in Ashfordly to keep an eye on him. The post office in Whitby goes on strike. Vernon Scripps gets the idea to start a courier service. And for once he does the dirty work himself.

Marek Starosta and his daughter Hannah are Lady Patricia's guests at Ashfordly Hall. They are world class violinists and shortly after their arrival they notice that a very valuable violin is missing. But Hannah is more interested in PC Crane, who is sent to investigate, than in playing the violin much to the annoyance of her father. And her feelings are returned. Marek Starosta also suffers from a form of arthritis which eventually will make it impossible for him to play. Big and Little Jim turn up in Aidensfield and ask for Vernon Scripps. They are his cousins from Liverpool. Big Jim suggests that they tear down the old Greengrass farm and build a mansion more suitable to Vernon's wealth instead.
