December 1938, and storm clouds hover once again over Europe. Josephine Tey and Archie Penrose gather with friends for a Cornish Christmas, but two strange and brutal deaths on St Michael's Mount - and the unexpected arrival of a world famous film star, in need of sanctuary - interrupt the festivities. Cut off by the sea and a relentless blizzard, the hunt for a murderer begins. Pivoting on a real moment in history, the ninth novel in the 'Josephine Tey' series draws on all the much-loved conventions of the Golden Age Christmas mystery, whilst giving them a thrilling contemporary twist.
