The Murder of Roger Ackroyd Summary: Christie's Most Argued-Over Mystery
What it is about
The Murder of Roger Ackroyd is Agatha Christie's third Hercule Poirot novel, published in the UK in June 1926 by William Collins, Sons. It had already appeared in serial form as Who Killed Ackroyd? in the London Evening News between July and September 1925. An American edition from Dodd, Mead and Company followed in 1926.
The story is set in King's Abbot, a small English village where very little stays private for long. Dr James Sheppard narrates. He is called out to certify the death of Mrs Ferrars, a wealthy widow who has taken her own life a year after the death of her abusive husband. His sister Caroline, who collects gossip the way other people collect stamps, decides at once that Mrs Ferrars poisoned her husband and killed herself out of guilt.
Roger Ackroyd, a rich widower who owns Fernly Park, asks the doctor to dinner because he needs to talk urgently. Afterwards, alone in his study, Ackroyd tells Sheppard that he and Mrs Ferrars had been secretly engaged, that she confessed to poisoning her husband, and that someone had been blackmailing her. She promised to name the blackmailer within a day. The butler then brings in a letter Mrs Ferrars posted just before her death. Ackroyd asks to read it alone.
Sheppard goes home. A phone call brings him straight back. Ackroyd is dead in his chair, stabbed with his own dagger, the study door locked, the letter gone and footprints leading in and out through an open window. Ackroyd's stepson Ralph Paton vanishes, the footprints match his shoes, and he becomes the obvious suspect. Ralph's fiancee Flora refuses to believe it and asks a newly retired Belgian detective who has moved to the village to look into it. Poirot agrees, and takes Dr Sheppard along as his companion on the case.
The main characters
Dr James Sheppard is the narrator and Poirot's helper, the village doctor who knows everyone's business and writes the account we are reading. Caroline Sheppard, his unmarried sister, gathers rumour and is often right. Hercule Poirot is in supposed retirement and pulled back to work by Flora's appeal.
At Fernly Park, the household includes Ackroyd's sister-in-law Mrs Cecil Ackroyd, her daughter Flora, Ackroyd's secretary Geoffrey Raymond, the family friend Major Blunt, the butler Parker and the parlourmaid Ursula Bourne, who has no alibi. Ralph Paton, Ackroyd's stepson, is absent for most of the book and all the more suspicious for it.
The themes
Justice runs through the book in a form Christie keeps turning over. Mrs Ferrars may have killed her husband and goes unpunished by any court. The blackmailer profits from a crime nobody has proved. Ackroyd is killed to stop the truth coming out. By the end, the question is less who did it than what should be done about it, and Poirot's answer is not the one a police procedural would give.
Identity is the other thread, and it works on two levels. Almost everyone at Fernly Park is hiding something: a secret engagement, a secret marriage, a servant who is not quite what she seems, an unspoken love. Flora admits things that change the timeline. Ralph's disappearance turns out to have a private explanation. The deeper game, though, is played with the narrator himself, which is where the book earned its reputation.
Why it still matters
The novel was well received from publication and has often been called Christie's masterpiece. In 2013 the British Crime Writers' Association voted it the best crime novel ever written. Howard Haycraft put it on his list of the most influential crime novels. It remains one of Christie's best known and most controversial books, because its ending broke a rule readers thought was fixed and forced the whole genre to rethink what a detective story could do to its audience.
It also works as a puzzle on its own terms. The clues are there: a moved chair, a phone call nobody admits to making, a short window of opportunity, a voice heard after the fact. Readers who go back a second time find the whole machine visible.
How it ends (full spoilers)
Poirot produces the missing Ralph Paton, who was already secretly married to Ursula Bourne when Ackroyd decided he should marry Flora. The two had met in the garden that night. Flora admits she never saw her uncle after dinner.
Then Poirot, alone with Sheppard, names him as both Mrs Ferrars's blackmailer and Ackroyd's killer. Sheppard stabbed Ackroyd before leaving the study, walked out the front door, put on Ralph's shoes, climbed back in through the window, locked the door from inside, started a dictaphone playing Ackroyd's recorded voice and moved a chair to hide it from the doorway. A patient was asked to ring him at home so he had a reason to return. When the body was found he pocketed the dictaphone in his medical bag and replaced the chair. His narrative simply left all of this out.
Poirot says he will go to the police in the morning and suggests Sheppard spare Caroline by taking his own life. The final chapter, Apologia, is Sheppard's suicide note.
