A 1926 mystery novel by Agatha Christie, The Murder of Roger Ackroyd was the book that propelled its author to fame, and is still widely regarded as one of her finest, and certainly among her most notable. Even today the Twist Ending remains controversial.
Mrs. Ferrars, a wealthy widow in a quiet English village, has apparently taken her own life. Local industrialist Roger Ackroyd, who was romantically involved with Mrs. Ferrars, confesses in private that his lover had admitted to him that she murdered her bullying, abusive, drunken husband with poison...and that someone had found this out, ruthlessly blackmailing her and driving her to suicide. Now, a letter in the post from Mrs. Ferrars is about to reveal all—but before Ackroyd can learn and expose the identity of the culprit, he is found dead in his study, stabbed viciously in the neck with his own ornamental dagger. An apparently open-and-shut case uncovers a likely suspect, but the village has by chance a new resident; Monsieur Hercule Poirot, the noted detective, who has retired to the countryside to grow vegetables. His legendary "little grey cells" intrigued by the case, Poirot soon discovers that all is not as it seems...
The story was adapted as an episode of Poirot in 2000; tropes concerning this adaptation can be found on the series page. The novel was also made into a Russian film in 2002, entitled Неудача Пуаро ("Neudacha Puaro" "Poirot's Failure").
And a quick note on spoilers: while every effort has been taken to avoid spoiling plot-crucial details regarding the novel on this page, the nature of the story (and the Twist Ending especially) means that it's hard to discuss without some kind of spoileriffic information slipping through. New readers should take that into account before proceeding on.
This detective mystery provides examples of:
- Affably Evil: The killer has a genuinely friendly and polite personality.
- Amateur Sleuth: Caroline Sheppard, the narrator's sister, makes a downplayed example. She's the town gossip, and her attempts to figure out the killer are Played for Laughs, particularly when she confides in her brother that she figured out the real murder weapon: poison! Cue Dr. Sheppard, baffled, pointing out that there was a knife found in Ackroyd's neck. Caroline confidently asserts "it was a false clue".
- Badass Boast: Hercule Poirot makes a point of warning the killer that the trick he pulled on Roger Ackroyd will be a lot more difficult to pull off on him.
- Bad Guys Do the Dirty Work: Even though it was motivated by entirely selfish reasons, the titular murder ends up saving quite a few people from some very tight spots. To wit...
- Ralph Paton becomes a fabulously wealthy man and is able to pay all his debts and start a new life with his wife Ursula.
- Flora becomes financially independent and is able to marry Major Blunt.
- Geoffrey Raymond, Ackroyd's secretary, was in considerable debt, but the £500 Ackroyd left him in his will cleared up that problem.
- Be as Unhelpful as Possible: If it weren't for so many of the suspects' efforts to conceal their own secrets, the killer wouldn't have had so easy a time setting up an alibi, to say nothing of the fact that they needlessly waste Poirot's time.
- Bitch in Sheep's Clothing: The killer. Leaving aside the obvious fact that he's revealed to be a blackmailer and murderer, re-reading the novel after the reveal suggests several hints that Dr. Sheppard isn't as nice as he likes to act, and indeed has a vein of arrogant, condescending superiority towards the people he's surrounded by.
- Blackmail: What triggered the whole series of events Dr. Sheppard figured out that Mrs. Ferrars poisoned her husband, and has been blackmailing her. Also, Poirot eventually finds out that Parker engaged in a bit of blackmail with his previous employer.
- Book-Ends: Invoked In-Universe. The story opens with the town reacting to Mrs. Ferrars' death from an overdose of Veronal. The ending reveals that Sheppard will kill himself by Veronal overdose, as a Death by Irony.
- Call to Agriculture: Poirot has retired from detective work at the beginning of the novel to grow marrows (a kind of squash).
- Cannot Spit It Out: Major Blunt can't confess his feelings for Flora Ackroyd. Naturally, Poirot helps him.
- Chekhov's Gun:
- The Dictaphone Company salesman's visit. Ackroyd did buy a dictaphone, and Sheppard used it to set up his alibi.
- Sheppard's wasted "legacy", mentioned early in the novel. In fact he received no legacy; he was blackmailing Mrs. Ferrars.
- A seemingly random reference early on about Sheppard seeing an American sailor patient. This is the person who unknowingly placed the crucial phone call.
- Chekhov's Hobby: Sheppard's hobby of fixing and inventing mechanics. This is how he rigged up the Dictaphone to play on a time delay.
- Contrived Coincidence: Considering that the murder was committed without any fore-planning whatsoever, the sheer number of other things going on at Fernly Park on that very same night that helped muddy the waters and create red herrings almost defies belief, from Flora choosing that very night to steal money, to Ursula giving her notice earlier in the day, to Russell's illegitimate son arriving at Fernly Park just as Dr. Sheppard was leaving the house.
- Crazy-Prepared: Sheppard, on pretty short notice, manages to steal Ralph Paton's shoes and arrange for a patient of his to place a crucial telephone call at a certain time all that without being completely sure what Roger Ackroyd wanted to talk about.
- Crushing Handshake: Major Blunt delivers a handshake that makes Poirot wince in pain after Poirot gives a little assistance with Blunt's love affair with Flora.
- Deadpan Snarker:
- Dr. Sheppard, at least as far as his sister is concerned.
- Poirot gets a few opportunities also:"Ah!" cried [Poirot]. "That, too, is my watchword. Method, order, and the little grey cells."
"The cells?" said the inspector, staring.
"The little grey cells of the brain," explained the Belgian.
"Oh, of course; well, we all use them, I suppose."
"In a greater or lesser degree," murmured Poirot.
- Death by Irony: Sheppard's death, which occurs by the same method as Mrs. Ferrars' suicide. And what makes it unusual it was deliberately planned so on the part of the killed one. "There would be a kind of poetic justice", as they put it.
- The Dog Was the Mastermind: Helpful, modest Dr. Sheppard, who is never suggested to have had any problem with Ackroyd, is revealed as the murderer. He killed Ackroyd to prevent Ackroyd from exposing him as a blackmailer.
- Driven to Suicide:
- Mrs. Ferrars, by the blackmailer.
- Dr. Sheppard, at the end. The final chapter is essentially his suicide note.
- The Ending Changes Everything: Sheppard is revealed as the murderer at the end, causing the reader to reassess everything they have read.
- English Rose: Flora is described as being blonde and blue-eyed with a pale complexion, as beautiful, and as a typical English girl.
- Everyone Is a Suspect: Almost every named character, including the narrator, is a suspect.
- There's even an alternative solution to the mystery, proposed by Pierre Bayard; see WMG page for details.
- Exactly What It Says on the Tin: It's about Roger Ackroyd. Who gets murdered.
- FaceHeel Turn: Dr. Sheppard was originally a good-ish but weak character who is tired of his thankless job, gave into the temptation of earning easy money via blackmail, and became evil as a result.
- Fair-Play Whodunnit: The way Poirot ultimately solves the crime is by reading what Dr. Sheppard wrote down, which is exactly what the reader is reading. Which means that an acute reader could actually pick up most of the important clues before Poirot does. Well, except possibly the dictaphone issue, which is still revealed just a bit before the final denouement. And there's also a matter of Dr. Sheppard's legacy but come on, you didn't even suspect he was capable of lying in the first place, did you?
- Funny Foreigner: Indulged in with Poirot as usual in Christie stories. In this one, he says "All my excuses for having deranged you" when he means "disturbed you."
- Gossipy Hens: Caroline Sheppard, who loves to be in everybody's business.
- Greedy Jew: Is it Christie indulging in anti-Semitism, or Christie engaging in some subtle negative characterization of Dr. Sheppard? Hard to say, but in any case, when Mrs. Ackroyd complains about being hounded by creditors, Sheppard says "I suspect a Semitic strain in their ancestry."
- Half Truth: Everything Sheppard puts in his journal is absolutely true. He doesn't put everything in his journal, though...
- He Knows Too Much: The reason Roger Ackroyd had to die. Though technically, he had been murdered before he had the chance to learn anything.
- Hidden Depths: Major Blunt claims that he hates going to the theatre (particularly opera), but some of his theatre-going experiences seem to have profoundly resonated with him; he compares a conversation he's in to "one of those Danish plays", presumably a reference to Scandinavian authors such as Henrik Ibsen.
- Hidden Heart of Gold: Caroline is a nag, a nosy gossip, and more than a little self-righteous, but at the sight of Ursula in tears she forgets everything in an attempt to comfort her. Lampshaded by Dr. Sheppard.
- Indy Ploy: The titular murder was committed almost entirely on the fly, as the murderer had hardly any time to plan it. It is testament to the killer's intelligence that what plan there was, was highly effective, and would've worked if Poirot hadn't become involved.
- The Killer in Me: The "Secretive Killer" variety, as Dr. Sheppard, who is narrating his and Poirot's investigation of the murder, is revealed at the end to be the murderer.
- Leave Behind a Pistol: Poirot gives the murderer the opportunity to settle accounts himself rather than wait for arrest the next day, in order to spare those close to him grief. It's not literally a pistol, though.
- MayDecember Romance: Major Blunt and Flora Ackroyd.
- Names to Trust Immediately: Dr. Sheppard is a subversion.
- No Name Given: Mrs. Ackroyd, widow of Roger's brother Cecil, is only referred to as "Mrs. Cecil Ackroyd".
- Nosy Neighbor: Caroline Sheppard, who is addicted to gossip and must know everything about everyone, like when Poirot moves in next door and she hounds her brother to find out about the new neighbour.
- Oddball in the Series: While most early novels and stories in the Hercule Poirot series are narrated by Poirot's friendly Watson, Captain Hastings, this one has a different narrator, helpful Dr. Sheppard. There's a perfectly logical Watsonian reason for this, as Hastings had already departed for Argentina by the time the events of the story occurred. But there's also a Doylist reason...
- Phoney Call: Part of Sheppard's alibi consists of arranging for a patient of his to call Sheppard on his way out of town. Sheppard pretends that this is notification of the murder, and then goes to Ackroyd's house to finish setting up his alibi.
- Realistic Diction Is Unrealistic: A plot point. Ackroyd was heard to be speaking in his study at 9:30, leading everyone to believe the murder must have happened after that. But what he was heard to say ("...the demands on my purse have been so frequent of late that I fear I cannot accede to your request...") strikes Poirot as something that nobody would have actually spoken in conversation with another person; it sounds far more as though Ackroyd were dictating a letter. This leads Poirot to deduce that Ackroyd was already dead by 9:30 and the words he was heard to speak were a Dictaphone recording.
- Reality Ensues: At one point Dr. Sheppard spontaneously invites Poirot to dinner, but unlike in most works of fiction, Caroline doesn't magically have extra food prepared to give him. She has to pretend to be vegetarian and serve Poirot the pork chop she was going to eat.
- Sarcasm-Blind: Most of the considerable sarcasm that Dr. Sheppard directs at his sister Caroline is taken literally by her.
- Secret Other Family: It turns out that the cause of Ralph's argument with Roger is that Ralph has married in secret, which puts a crimp in Roger's plans for an Arranged Marriage with Flora. Specifically, he's married Ursula, the parlourmaid.
- Sequencing Deception: As Sheppard admits in the final chapter, while everything he writes in the story is true, he left stuff out. For example, he writes that Roger received the letter at 8:40 and Sheppard left at 8:50, but doesn't mention that he killed Ackroyd in the interim.
- Slowly Slipping Into Evil: Dr. Sheppard, upon discovering a murder, gives into the temptation to commit blackmail and then kills to protect themselves.
- Starts with a Suicide: Mrs. Ferrars's suicide from a Veronal overdose.
- Summation Gathering: Subverted. The assembled parties leave without hearing the murderer identified that is left to the private exchange between Poirot and the murderer that immediately follows.
- Terse Talker: Major Blunt.
- Tomato Surprise: By necessity, as Sheppard (the narrator) doesn't reveal that he is the murderer until Poirot confronts him.
- Twist Ending: Dr. Sheppard, the polite Watson of this story and also the narrator, is revealed to be the murderer.
- Unreliable Narrator: A doozy of an example. Dr. Sheppard, who has been narrating the story in classic Watson-style, is the murderer. Sheppard NEVER tells a single lie (to us readers, that is; he only lies to Poirot and the others), nor does he even resort to truthful but misleading statements. He simply leaves something out. It should also be noted the number of times the narrator writes about being puzzled and confused about aspects of the case; he's being completely honest each time. Every suspect has something to hide, from the embarrassing to the outright criminal, and has lied to cover it up. A great example is Ackroyd's niece, who claims she spoke to Ackroyd around a quarter to 10 on the night of the murder, something Sheppard knows is impossible. It turns out she had stolen some cash from Ackroyd's upstairs bedroom, saw the butler approaching as she was heading down the stairs, and rushed down the stairs, pretending she'd come from the study, and claimed to have just spoken to her uncle.
- The Watson: Dr. Sheppard, filling in for Captain Hastings. The role of Sheppard as Watson is lampshaded.
- Wham Line: "In fact Dr. Sheppard!"
- Writing About Your Crime: Dr. Sheppard writes an account of the murder and Poirot's subsequent investigation, leaving out the fact that he himself is the murderer. He is careful to never actually lie in his manuscript, but to just leave out pertinent facts in order to mislead the reader.
- You Meddling Kids: The last line of the book."But I wish Hercule Poirot had never retired from work and come here to grow vegetable marrows."
