Agatha Christie's Spookiest Mysteries
Séances that spell out murder, a village inn run by self-proclaimed witches, cursed land and a Halloween party that ends in the apple-bobbing tub. Nine Christie books for October, with where to stream the adaptations in the US.

Christie and the Supernatural
Agatha Christie built her reputation on rational solutions, but she borrowed the trappings of the ghost story again and again: séances, curses, witchcraft, isolated houses. In most of these books the spooky atmosphere is a smokescreen for a very human killer, which is what makes them such good October reading. Two short-story collections at the end of this list go further and are genuinely supernatural.
The Halloween Essentials
The two Christie novels that lean hardest into October: one set at an actual Halloween party, one built around a trio of self-proclaimed witches.
Hallowe'en Party
At a children's Halloween party in the village of Woodleigh Common, a girl boasts that she once witnessed a murder, and before the night is over she is found drowned in the apple-bobbing tub. Ariadne Oliver calls in Poirot, and between the snapdragon and the party games, this is Christie's most obvious October read.
The Pale Horse
A mysterious list of names leads Mark Easterbrook to the Pale Horse, a former inn in the village of Much Deeping whose three residents claim they can kill from a distance. It's Christie at her most occult, with a very Christie twist hiding behind the black magic.
Séances and Spiritualists
Table-turning and ghostly glows: two cases where the spirit world seems to have something to say about murder.
The Sittaford Mystery
On a snowbound evening on Dartmoor, a game of table-turning at Sittaford House spells out a message: Captain Trevelyan is dead. Six miles away in Exhampton, he is found murdered, and Emily Trefusis sets out to clear her fiancé.
Dumb Witness
Emily Arundell writes to Poirot about a suspicious fall down the stairs, but her letter reaches him late and by the time he arrives she is already dead. Her neighbours, the spiritualist Tripp sisters, noticed something strange during a séance with her, and it matters more than anyone realises.
Curses, Witches and Isolated Places
No séances here, just local legends, village whispers of black magic, and one island nobody leaves.
Endless Night
Michael Rogers falls for a piece of land called Gipsy's Acre, and for the heiress who buys it, despite local talk of a curse and an old woman who keeps warning them to leave. One of Christie's darkest late novels, and far closer to gothic suspense than a cosy whodunit.
Murder Is Easy
On a train to London, retired policeman Luke Fitzwilliam meets an elderly woman on her way to report a killer to Scotland Yard, and the next day he reads that she has been killed by a car. In the village of Wychwood under Ashe he finds gossip, suspicions of black magic, and a run of deaths nobody else seems to question.
And Then There Were None
Ten strangers are lured to Soldier Island off the Devon coast, accused of past crimes, and killed one by one in the pattern of a nursery rhyme. No detective, no ghosts, and no way off the island, just a steadily shrinking guest list.
Christie's Genuinely Supernatural Stories
Most of Christie's ghosts turn out to have a rational explanation. These two collections venture much further into genuinely supernatural territory, and neither has a current TV adaptation, so they're for reading by lamplight.
The Hound of Death
Christie's most openly supernatural collection: twelve tales of premonitions, strange powers and a haunted house, including a séance that goes terribly wrong in The Last Séance. It also includes The Witness for the Prosecution, the one story in the book with no ghostly element.
The Mysterious Mr Quin
The observant Mr Satterthwaite keeps crossing paths with Harley Quin, a stranger who appears exactly when he is needed, vanishes again, and may not be entirely of this world. Christie counted the pair among her favourite characters.
Where to Watch in the US
These three services currently carry the adaptations featured on this page in the US. Availability can change, so it's worth double-checking a title before settling in.
What Readers Ask Most
Which Agatha Christie novel is set at Halloween?
Hallowe'en Party (1969), in which Poirot and Ariadne Oliver investigate a death at a children's Halloween party in the village of Woodleigh Common. David Suchet's adaptation is part of Series 12 of Agatha Christie's Poirot.
Are Agatha Christie's spooky stories actually supernatural?
Usually not. In novels like The Pale Horse and The Sittaford Mystery, the séances and witchcraft have a human explanation. The short-story collections The Hound of Death and The Mysterious Mr Quin venture much further into genuinely supernatural territory.
Is A Haunting in Venice based on Hallowe'en Party?
Loosely. Kenneth Branagh's 2023 film takes its starting point from Hallowe'en Party but moves the story to Venice. For a version closer to the novel, the David Suchet episode keeps the English village setting.
Where can I watch these Agatha Christie adaptations in the US?
The Poirot episodes and the 2023 Murder Is Easy are on BritBox. The Marple versions of The Pale Horse, The Sittaford Mystery and Endless Night, plus the 2015 And Then There Were None, are on Acorn TV. The 2020 BBC version of The Pale Horse streams on Prime Video.
Which spooky Christie book should I read first?
Hallowe'en Party if you want Poirot and a proper Halloween setting. And Then There Were None if you want the most suspense, and The Pale Horse if you want witches.
