Miss Tayke and her whimsical friends Cedric and Bunty find themselves embroiled in two disparate murder mysteries in the lead up to Christmas. The first involves the sadistic poisoning of the young fiance of the curate of St Aidan's parish church while they are embracing under the mistletoe at a festive celebration. Hardly has Miss Tayke solved this mystery when another follows hard on its heels: a knife-crazed maniac is on the loose slaying everyone wearing a Santa Claus outfit on the high street of Easter village. Miss Tayke and her friends join forces with the police to track down the killer."
