Colonel de Luce, in desperate need of funds, rents his beloved estate of Buckshaw to a film company. They will be shooting a movie over the Christmas holidays, filming scenes in the decaying manse with a reclusive star. She is widely despised, so it is to no one's surprise when she turns up murdered, strangled by a length of film from her own movies! With a blizzard raging outside and Buckshaw locked in, the house is full of suspects. But Flavia de Luce is more than ready to put aside her investigations into the true identity of Father Christmas to solve this yuletide country-house murder.
