PlayIt's the week before Christmas in Aidensfield and young fir trees are being stolen from the estate of Lord and Lady Whitley, presumably for sale as Christmas trees.
The beautiful Lady Whitley calls PC Nick to the scene of the crime in the middle of the night to investigate.
Nick and Blaketon jump to the obvious conclusion when Greengrass sells a tree to George, licensee of the Aidensfield Arms.
It seems to be confirmed when Greengrass's allegedly stolen lorry turns up covered in pine needles.
