Christmas is near and Kate Rowan has arranged that Danny Parkin, who is very ill, gets home from hospital during the holidays. A trip to a sanatorium in Switzerland will do wonders for him and to earn money for the trip his siblings "borrows" Christmas trees from Lady Whitly's estate in order to sell them. The snobby, but very attractive Lady Whitly shows a lot of affection for PC Rowan, who is sent to investigate, and she is also involved in the local Christmas charity concert. The same concert needs a Santa Claus and a reluctant Greengrass is hired for the job. Not surprisingly he tries to make money on the deal. And speaking of Greengrass, somebody has nicked his lorry!

Joe Norton and two of his friends are terrorizing Aidensfield and they do not even refrain from emptying PC Rowans garbage bin. Nicking laundry does not seem to be above them either. The traveling gipsy Flo arrives in Aidensfield and tries to make some money by selling luck in the form of small bouquets of lucky heather. Those who do not buy are struck with bad luck, which Greengrass finds out to his discomfort. It does not take long before Norton and his gang set their sights on her caravan. Kate Rowan discovers the real reason for her nosebleed and extravasations. And she is rushed to hospital when she goes into labour.

Harry Schofield's great ambition is that his son Len becomes a professional cricket player, but when Len is not accepted at cricket training, he runs away from home. Joss Harrop has a couple of mares he wants covered, but stud fees have risen and he cannot afford it. Greengrass has a perfect solution to that. They "borrow" lord Ashfordly's race horse Ashfordly Lad for a couple of hours and return the stud before anybody notices it is missing. That is a lot easier said than done. Not getting hold of the horse that is, but returning it!

Jean Lightfoot believes she is being followed and she receives mysterious phone calls. One day she finds a strange, well dressed woman at her doorstep, Susan Williamson, who claims to be an old sweetheart of Jean's husband Derek, but he says he has never seen her before. The Australian couple Len and Julie Wilcox is in Aidensfield to look for relatives. When Greengrass discovers they have plenty of money he offers his services to them - for a small fee of course. He also discovers that they are distant relatives of his and tries to sell them "valuable heirlooms". Jo and her father have to cope with her mother's death and take care of funeral arrangements.
