The Ashfordly team investigate sinister goings-on at the houses of two very different women in Aidensfield. Could it be the work of a dead legendary servant girl who has come back to haunt her old manor? or is there a much simpler, less supernatural answer to the mystery? Meanwhile, Craddock's wife Penny is organizing a Christmas dancing competition, with Greengrass and David providing the trophy. At the dance, Blaketon and Aunt Mary steal the show, Mike and Jackie's romance blossoms, and much to Bellamy's delight, Sue Driscoll returns.
