“Love Flavia!! Christmas is coming and the snow is falling, but with the de Luce family finances in a parlous state, it's set to be a bleak mid-winter at Buckshaw. Which is why Colonel de Luce has - with deep misgivings - agreed to rent out the family home to a film company looking for the perfect English country house location.
But filming is soon slowed by a series of nasty accidents - and then brought to a halt as a heavy snowstorm cuts Buckshaw off from the outside world. As the family, an assortment of stranded villagers, and the increasingly fractious film crew prepare to wait the weather out, they are stunned by a gruesomely dramatic murder, and suddenly Flavia - in the midst of designing a scientific experiment to prove the existence of Father Christmas - has another far deadlier mystery to solve.”
