The Sittaford Mystery is a standalone novel by Agatha Christie, first published in 1931, set in the remote, snowbound village of Sittaford on the edge of Dartmoor. The plot begins when a group of people at a remote house decide to hold a séance, during which they receive a chilling message that a retired naval officer, Captain Trevelyan, has been murdered. The weather makes it impossible to contact the outside world immediately. A young, determined woman named Emily Trefusis, who is engaged to the chief suspect's son, travels through the blizzard to investigate. The narrative is a classic locked-room setup blended with a race against the elements. It features a resourceful amateur sleuth and cleverly utilizes the isolation of the setting to maximize suspense and misdirection, making it a classic example of Christie’s ability to weave intricate plots.
