On Christmas Eve, heavy snowfall brings a train to a halt near the village of Hemmersby. Several passengers take shelter in a deserted country house, where the fire has been lit and the table laid for tea – but no one is at home. Trapped together for Christmas, the passengers are seeking to unravel the secrets of the empty house when a murderer strikes in their midst. This classic Christmas mystery is republished for the first time since the 1930s, with an introduction by the award-winning crime writer Martin Edwards.
