A blinding snowstorm—and a homicidal maniac—traps a small party of friends in an isolated estate. The plot takes on a claustrophobic feeling that leads to an unexpected end. Out of this deceptively simple set-up, Agatha Christie fashioned one of her most ingenious puzzlers; one that later became a successful play. “This classic title novella showcases the inimitable Christie at her inventive best, proving her reputation as ‘the champion deceiver of our time’.” (The New York Times)
