A murderer stalks the halls of an isolated snowbound Sussex hotel

Inspector Lane Perry of Scotland Yard finds himself on a busman's holiday when he is forced to take refuge from a heavy snowstorm in a country hotel while traveling in Sussex in January 1948. When he first glimpses the hotel guests frolicking in the snow, he mistakes them for lunatics at play. Instead, he learns they are all guests invited to attend a homecoming party for a war hero.
But when the battered body of Wing Commander Lawton Lawrence turns up in the snow, Parry realizes that playtime is over and that a murderer is walking the halls of Beechlands.
