The A.B.C. Murders is a work of detective fiction by British writer Agatha Christie, featuring her characters Hercule Poirot, Arthur Hastings and Chief Inspector Japp, as they contend with a series of killings by a mysterious murderer known only as "A.B.C.". The book was first published in the UK by the Collins Crime Club on 6 January 1936, sold for seven shillings and sixpence (7/6) while a US edition, published by Dodd, Mead and Company on 14 February of the same year, was priced $2.00.
The form of the novel is unusual, combining first-person narrative and third-person narrative. This approach was previously used by Agatha Christie in The Man in the Brown Suit. In The A.B.C. Murders the third-person narrative is supposedly reconstructed by the first-person narrator of the story, Arthur Hastings.
The initial premise is that a serial killer is murdering people with alliterative names. The murders follow an alphabetical order, starting with a victim whose initials were A. A., and appear to lack a motive.
The novel was well received in the UK and the US when it was published. One reviewer said it was "a baffler of the first water", while another remarked on Christie's ingenuity in the plot. A reviewer in 1990 said it was "a classic, still fresh story, beautifully worked out".

Plot
Returning from South America, Arthur Hastings meets with his old friend, Hercule Poirot, at his new flat in London. Poirot shows him a mysterious letter he has received, signed "A.B.C.", that details a crime that is to be committed very soon, which he suspects will be a murder. Two more letters of the same nature soon arrive at his flat, each before a murder being carried out by A.B.C., and committed in alphabetical order: Alice Ascher, killed in her tobacco shop in Andover; Elizabeth "Betty" Barnard, a flirty waitress killed on the beach at Bexhill; and Sir Carmichael Clarke, a wealthy man, killed at his home in Churston. In each murder, an ABC Rail Guide is left beside the victim.
The police team for the investigation, led by Chief Inspector Japp, includes Inspector Crome, who doubts Poirot's detective abilities, and Dr. Thompson, who tries to profile the killer. Poirot forms a "Legion" of relatives of the deceased to uncover new information: Franklin Clarke, Sir Carmichael's brother; Mary Drower, Ascher's niece; Donald Fraser, Betty's fiancé; Megan Barnard, Betty's elder sister, and Thora Grey, Sir Carmichael's young assistant. Following a meeting with the third victim's widow, Lady Clarke, one key similarity between the murders is established – on the day of each murder, a man selling silk stockings has appeared at or near each crime scene. Despite this information, Poirot wonders why the letters were sent to him, rather than the police or the newspapers, and why the third letter misspelled Poirot's address, causing a delay in his receipt of it. Soon, A.B.C. sends his next letter, directing everybody to Doncaster, where it is suspected that the next murder will occur at the St. Leger Stakes race meeting that day. However, the murderer strikes at a cinema instead, and the victim's name does not match the alphabetical pattern of the other killings.
The police soon get a tip-off about the man linked to the murders – Alexander Bonaparte Cust, an epileptic travelling salesman, who suffers from memory blackouts and constant agonising headaches as the result of a head injury during the First World War. Cust flees his apartment but collapses upon arriving at the Andover police station, where he is taken into custody. Apart from claiming that a stocking firm hired him, he lacks any memory of committing the murders but believes he must be guilty of them – he had been at the cinema when the last murder occurred and found blood on his sleeve and a knife in his pocket after he had left. The police learn that the firm in question never hired Cust. Their search of his room turns up an unopened box of ABC railway guides and the typewriter and fine paper used in A.B.C.'s letters, while the knife is discovered in the hallway outside his room where he dropped it. Poirot doubts Cust's guilt because of his memory blackouts, and especially because he had a solid alibi for the Bexhill murder.
Characters
Hercule Poirot – Renowned Belgian detective, involved in investigating the serial killings by A.B.C., due to letters received from him.

Literary significance and reception
The Times Literary Supplement on 11 January 1936 concluded, with a note of admiration for the plot that, "If Mrs Christie ever deserts fiction for crime, she will be very dangerous: no one but Poirot will catch her."
Isaac Anderson in The New York Times Book Review of 16 February 1936 finished his review by writing, "This story is a baffler of the first water, written in Agatha Christie's best manner. It seems to us the very best thing she has done, not even excepting Roger Ackroyd."
In The Observer's issue of 5 January 1936, "Torquemada" (Edward Powys Mathers) wrote, "Ingenuity ... is a mild term for Mrs Christie's gift. In The A.B.C. Murders, rightly chosen by the [crime] club as its book of the month, she has quite altered her method of attack upon the reader, and yet the truth behind this fantastic series of killings is as fairly elusive as any previous truth which Poirot has had to capture for us. The reader adopts two quite different mental attitudes as he reads. At first, and for a great many pages, he is asking himself: "Is Agatha Christie going to let me down? Does she think she can give us this kind of tale as a detective story and get away with it?" Then the conviction comes to him that he has been wronging the authoress, and that he alone is beginning to see through her artifice. In the last chapter he finds, because brilliant circus work with a troop of red horses and one dark herring has diverted his attention from a calm consideration of motive, he has not been wronging, but merely wrong. It is noticeable, by the way, that characters break off at intervals to tell us that we have to do with "a homicidal murderer". We are ready to take this for granted until Mrs Christie (I wouldn't put it past her) gives us one who isn't."
E R Punshon reviewed the novel in 1936, writing that "Some readers are drawn to the detective novel by the sheer interest of watching and perhaps anticipating the logical development of a given theme, others take their pleasure in following the swift succession of events in an exciting story, and yet others find themselves chiefly interested in the psychological reactions caused by crime impinging upon the routine of ordinary life. Skilful and happy is that author who can weave into a unity this triple thread. In Mrs Agatha Christie's new book...the task is attempted with success." He added, "In the second chapter, Mrs Christie shows us what seems to be the maniac himself. But the wise reader, remembering other tales of Mrs Christie's, will murmur to himself 'I trust her not; odds on she is fooling me,' and so will continue to a climax it is not 'odds on' but a dead cert he will not have guessed. To an easy and attractive style and an adequate if not very profound sense of character Mrs Christie adds an extreme and astonishing ingenuity, nor does it very greatly matter that it is quite impossible to accept the groundwork of her tale or to suppose that any stalking-horse would behave so invariably so exactly as required. As at Bexhill, a hitch would always occur. In the smooth and apparently effortless perfection with which she achieves her ends Mrs. Christie reminds one of Noël Coward; she might, indeed, in that respect be called the Noël Coward of the detective novel."
References to other works
In Chapter 1, Poirot alludes to a situation in the 1935 novel, Three Act Tragedy. In the same chapter, Poirot mentions his failed attempt at retirement to grow vegetable marrows as depicted in The Murder of Roger Ackroyd.
In Chapter 3, an exchange between Japp and Poirot shows that, in 1935, Christie was already thinking about Poirot's death as later narrated in Curtain: "I shouldn't wonder if you ended by detecting your own death," said Japp, laughing heartily. "That's an idea, that is. Ought to be put in a book." "It will be Hastings who will have to do that," said Poirot, twinkling at me. "Ha ha! That would be a joke, that would," laughed Japp."
Still in Chapter 3, Poirot lays out the plot of what he considers a perfect crime, a crime so challenging that "even he" would find it hard to solve. This exact murder – where someone is murdered by one of four people playing bridge in the same room with him – is the subject of Christie's Cards on the Table, which was published later in the same year and which, in turn, features Hercule Poirot and has another character refer to him as the man who solved the ABC murders.
In Chapter 19, Poirot reflects over his first case in England, where he "brought together two people who loved one another by the simple method of having one of them arrested for murder". This is a reference to the novel The Mysterious Affair at Styles, and the lovers mentioned are John and Mary Cavendish.

The plot of The A.B.C. Murders is mentioned by Detective Inspector John Appleby in Michael Innes′ novel Appleby's End (1945).
Chapters 393–397 of Gosho Aoyama's manga Detective Conan feature a case with some similarities as the criminal was inspired by the plot of The A.B.C. Murders. Episodes 325–327 of its anime adaptation also featured the incident. The 1998 anime film Case Closed: The Fourteenth Target is a combination of this story, with a murderer killing based on numbers in names as a ruse to confuse detectives, while also incorporating Christie's And Then There Were None.
A Bengali detective novel of Narayan Sanyal 'O Aa Ka Khuner Kanta' was based on The A.B.C. Murders. Sanyal admitted the inspiration from Christie's novel in the introduction to the book. Here the character P. K. Basu, Bar-at-law, has the role of main protagonist, similar to Poirot.
Film, TV and other adaptations
Film
The first adaptation of the novel was the 1965 film The Alphabet Murders with Tony Randall as Hercule Poirot, a version far more comic than mysterious.
The story of the 2012 Malayalam film Grandmaster written by director B. Unnikrishnan draws inspirations from The A.B.C. Murders. The characterisation of Chandrasekhar in the movie as played by the Indian movie veteran Mohanlal, while inspired by that of the legendary Hercule Poirot, has more to do with the popular established screen persona of Mohanlal in Malayalam.
