The Mystery of the Blue Train is a work of detective fiction by British writer Agatha Christie, first published in the United Kingdom by William Collins & Sons on 29 March 1928[1] and in the United States by Dodd, Mead and Company later in the same year.[2][3] The UK edition retailed at seven shillings and sixpence (7/6)[4] and the US edition at $2.00.[3] The book features her detective Hercule Poirot.

The novel concerns the murder of an American heiress on Le Train Bleu, the titular "Blue Train". The novel entered the public domain in the United States in 2024;[5] however, it will still be copyrighted in the United Kingdom until 1 January 2047, 70 years after the death of Agatha Christie.[citation needed]

Plot summary

Poirot boards Le Train Bleu, bound for the French Riviera. So does Katherine Grey, who is having her first winter out of England, after recently receiving a relatively large inheritance. On board the train Grey meets Ruth Kettering, an American heiress leaving her unhappy marriage to meet her lover. The next morning, though, Ruth is found dead in her compartment, a victim of strangulation.

The famous ruby, "Heart of Fire", which had recently been given to Ruth by her father, is discovered to be missing. Ruth's father, American millionaire Rufus Van Aldin, and his secretary, Major Knighton, persuade Poirot to take on the case. Ruth's maid, Ada Mason, says that she saw a man in Ruth's compartment but could not see who he was. The police suspect that Ruth's lover, the Comte de la Roche, killed her and stole the ruby, but Poirot does not think that the Comte is guilty. He is suspicious of Ruth's estranged husband, Derek Kettering, who was on the same train but claims not to have seen Ruth. Katherine says that she saw Derek enter Ruth's compartment. Further suspicion is thrown on Derek when a cigarette case with the letter "K" is found there.

Poirot investigates and finds out that the murder and the jewel theft might not be connected, as the famous jewel thief "The Marquis" is connected to the crime. Eventually, the avaricious Mirelle, who was on the train with Derek—with whom she had been having an affair but, now spurned, is seeking revenge against him—tells Poirot she saw Derek leave Ruth's compartment around the time the murder would have taken place. Derek is then arrested. Everyone is convinced the case is solved, but Poirot is not sure. He does more investigating and learns more information, talking to his friends and to Katherine, eventually coming to the truth.

He asks Van Aldin and Knighton to come with him on the Blue Train to recreate the murder. He tells them that Ada Mason is really Kitty Kidd, a renowned male impersonator and actress. Katherine saw what she thought was a boy getting off the train, but it was really Mason. Poirot realised that Mason was the only person claiming to have seen anyone with Ruth in the compartment, so this could have been a lie. He reveals that the murderer and Mason's accomplice is Knighton, who is really the ruthless "Marquis". He also says that the cigarette case with the K on it does not stand for 'Kettering', but for 'Knighton'. Since Knighton was supposedly in Paris, no one would have suspected him. Derek did go into the compartment to talk to Ruth once he saw she was on the train, but he left when he saw she was asleep. The police arrest Knighton and the case is closed.

Influence and significance

(Learn how and when to remove this message)

The novel's plot is based on the 1923 Poirot short story "The Plymouth Express"[8] (later collected in book form in the US in 1951 in The Under Dog and Other Stories and in the UK in 1974 in Poirot's Early Cases).[citation needed]

The novel "also contains a number of firsts", which include "reference to the fictional village of St. Mary Mead... [later] the home of Agatha Christie's detective Miss Marple",[8] in this work, the home of the character, Katherine Grey.[citation needed] (This location also appear in "The Tuesday Night Club", published in December 1927, the first short story to feature Miss Marple.[citation needed]) Also fists were "appearance of Poirot's valet, George" and "of the minor recurring character, Mr Goby, who would also appear in After the Funeral and Third Girl".[8]

Mere months after this novel was published, prolific French novelist Arthur Bernède published Le mystère du train bleu, in 1928.[9] A murder mystery adventure featuring Bernède's own popular detective, Chantecoq, the story is set in Paris and the plot is completely different, although it seems likely[original research?][editorializing] that Bernède was hoping to benefit from Poirot's popularity.[citation needed]

Literary significance and reception

The Times Literary Supplement gave a more positive reaction to the book than Christie herself in its issue of 3 May 1928. After recounting the set-up of the story, the reviewer concluded: "The reader will not be disappointed when the distinguished Belgian on psychological grounds... builds up inferences almost out of the air, supports them by a masterly array of negative evidence and lands his fish to the surprise of everyone".[8][10]

The New York Times Book Review of 12 August 1928 said, "Nominally Poirot has retired, but retirement means no more to him than it does to a prima donna. Let a good murder mystery come within his ken, and he just can't be kept out of it."[11]

British crime writer and critic Robert Barnard declared: "Christie's least favourite story, which she struggled with just before and after the disappearance. The international setting makes for a good varied read, but there is a plethora of sixth-form schoolgirl French and some deleterious influences from the thrillers. There are several fruitier candidates for the title of 'worst Christie'."[12]

Allusions

Allusions to other works in the Christie cannon include the following. One of the characters in Death on the Nile recognises Poirot because of his involvement in The Mystery of the Blue Train: "Miss Van Schuyler said: ' I have only just realised who you are, Monsieur Poirot. I may tell you that I have heard of you from my old friend Rufus Van Aldin." That line was retained in the television film, even though Death on the Nile was broadcast first.

The novel features a Wagon Lit conductor called Pierre Michel which is the same name of another Wagon Lit conductor who appears in Murder on the Orient Express – it is never revealed whether these two characters are one and the same or different.

The titular Blue Train appears again in Three Act Tragedy where Poirot boards the train with Sir Charles Cartwright to return to England.

Adaptations

Television

The novel was adapted for television in 2006,[8] a special episode of the series Agatha Christie's Poirot, airing on ITV on 1 January.[citation needed] It adapted by Guy Andrews and directed by Hettie Macdonald (who would later Curtain: Poirot's Last Case), and starred David Suchet as Poirot.[8] Also featured were Roger Lloyd-Pack as Inspector Caux, James D'Arcy as Derek Kettering, Lindsay Duncan as Lady Tamplin, Alice Eve as Lenox and Elliott Gould as Rufus Van Aldin.[citation needed] It was "[r]eset in the late 1930s to match the rest of the Poirot TV series".[8]
