The villains from the novels and short story collections by the British mystery novel writer, the late Dame Agatha Mary Clarissa Christie (15 September 1890 – 12 January 1976), who is famous for her creation of Hercule Poirot, one of the most legendary fictional detective in literature history. Other notable characters in her works includes but not limited to Miss Jane Marple.

It also contains villains from all kinds of adaptations of her various works, including ITV's TV series adaptation, Agatha Christie's Poirot and Agatha Christie's Marple.

IMPORTANT NOTES[]

Shared Universe[]

• It should be noted that the majority (if not all) of Dame Christie's mystery stories happens under the SAME CONTINUTY, particularly those that involves Hercule Poirot and his allies. Evidence include:
  • Poirot and Arthur Hastings being mentioned and referred in non-Poirot stories like Towards Zero and Partners in Crime as celebrities in-universe.
  • Notable supporting characters in Poirot stories has appeared as protagonists in other novels, particularly Colonel Race in Sparkling Cyanide and Superintendent Battle in Towards Zero, both of them worked with Poirot in Cards on the Table.
  • Recurring characters also includes Mrs. Ariadne Oliver and Miss Lemon, who appears as a recurring character in Poirot novels, but had already made their debut appearance in Parker Pyne Investigates before that. Mrs. Oliver also appeared in a later novel named The Pale Horse, where Poirot's investigation in Cards on the Table was directly referenced.
• While Poirot and Arthur Hastings are referenced as fictional characters in it, the Tommy and Tuppence series is still considered to be a part of Agatha Christie's mystery novel universe, with several supporting characters from Miss Marple's story made their appearance.
• The category also includes the culprits that were introduced in Sophie Hannah's Hercule Poirot continuation novels, including The Monogram Murders (2014), Closed Casket (2016) and The Mystery of Three Quarters (2018). Sophie Hannah's Poirot novels are officially licensed by the estate of Agatha Christie and thus become canonical.

Regarding the Non-culprits[]

• Non-culprit supporting characters that are merely not well-liked, obnoxious, selfish and/or acting as a jerk does not count. (e.g. James Ferguson from Death on the Nile, Monsieur Giraud from The Murder on the Links) They must have done villainous deeds, including but not always murder. (e.g. The Crofts & Freddie Rice's husband in Peril at the End House) However, if they were presented as villains in adaptations, they will be included, but only specifically on the adaptational version.

Regarding the Villainous Victims[]

• The villains obviously include murderers of their respective stories. However, in some (but not rare) cases, there are several victims in Dame Christie's works who are revealed to be villainous. Some victims turned out to be the true criminal, while some are even more despicable than their murderers, to the point of even making the killers sympathetic (if they didn't kill for selfish motives).
  • Victims that are merely not well-liked, obnoxious, selfish and/or acting as a jerk does not count (e.g. Mr. Shaitana from Cards on the Table, and Joyce Reynolds from Hallowe'en Party).
  • The villainous victim should be depraved and unscrupulous, at least they had committed crimes and/or unscrupulous acts such as blackmail, theft, abuse, lover stealing, murder, extortion, kidnapping and/or being accomplices to murder. (e.g. literally ALL OF THE MAIN CHARACTERS from And Then There Were None, Lady Boynton from Appointment With Death, Louise Bourget from Death on the Nile, Lanfranco Cassetti from Murder on the Orient Express, and Simeon Lee from Hercule Poirot's Christmas)

Regarding Specific Criminals[]

• If a criminal's crimes (including murders) were out of righteous reason (like self-defense and seek of justice) and has no self-serving purpose, they should be included on the Heroes Wiki instead. (e.g. All of the culprits from Murder on the Orient Express, since they murdered a notorious criminal for righteous reasons, and didn't commit more criminal acts beyond that.)
• NOTE: Countess Vera Rosakoff is the ONLY character in this franchise that is on both the Heroes Wiki and the Villains Wiki at the same time. This is because of her special role as both a redeemed criminal (albeit without any murder history), and an more supportive anti-hero in her later appearances.
