The Return to Styles
Traveling by train through Essex, widowed [Arthur Hastings](entity:character-recall-character-arthur-hastings-24d362cbed89) recalled the scene when he first arrived at [Styles](entity:location-recall-location-styles-3971dba4ed9f) in early [1916](entity:time-recall-time-1916-26647d28bae8). He was young, wounded, and did not know that this journey would change the course of his life. The old house and everyone inside had changed, and his

The Luttrells’ Guest House
Daisy Lutrel met Hastings with a warm attitude, yet she could not hide her shrewd and pragmatic firmness. Her husband, George Lutrel, seemed nervous and submissive. The desolate garden and cheaply converted rooms testified to how the couple tried to turn the old house into

Poirot’s Decline
Hastings found Poirot emaciated, suffering from arthritis and unable to leave his wheelchair; however, his sharp eyes and formidable confidence remained unchanged. Poirot complained about the food and various inconveniences at Stiles' mansion, then clearly stated that neither poverty nor nostalgia had prompted
Poirot’s first briefing at Styles
Five Earlier Cases
Poirot summarized five deaths: Leonard Eatherington died from poisoning with arsenic, [Miss Sharples](entity:character-recall-character-miss-sharples-0de6f97f004c) died from an overdose of morphine, [Edward Riggs](entity:character-recall-character-edward-riggs-c6984f5e9d69) and [Ben Craig](entity:character-recall-character-ben-craig-5f6596c35cda) were shot, [Derek Bradley](entity:character-recall-character-derek-bradley-202f30fc904a) died from cyanide poisoning, and Matthew Lychfield was killed. Each case seemed to have a
immediately after the case briefing
A Murder Foreseen
Hastings insisted that Poirot should have been able to prevent the predicted crime. Poirot explained the difficulties: the identity of the victim was unknown, and warnings might not be effective; to ensure the success of the intervention, it was necessary to know exactly the method and timing of the
Hastings’s first evening at Styles
Judith Returns
[Judith Hastings](entity:character-recall-character-judith-hastings-dbefed46d6ef) met her father with her usual reserve. She is an outstanding researcher, serving as an assistant to Dr. [John Franklin](entity:character-recall-character-john-franklin-5a0d2581aedb), helping to study tropical diseases; Hastings was worried that she was so devoted to her work that she had little room for personal life
the first dinner at Styles
The Household Takes Shape
Hastings met Elizabeth Coler, a cautious and attractive woman, and Major Alerton, a charming but notorious ladies' man. Alerton effortlessly handled women, winning their favor, including Judith; Hastings, however, immediately felt distrust towards him. In private, Hastings compared each man in
the first evening after dinner
Judith’s View of Mercy
On the terrace, Judith questioned Hastings' view of authority and how the old man binds the young. She believed that the weak or selfish might trap a capable life in a cage; she also spoke passionately about an old tyrant—his daughter killed him, freeing the whole family
the first night at Styles
Franklin’s Marriage
Hastings visited the frail patient [Barbara Franklin](entity:character-recall-character-barbara-franklin-88d530461db0) and met the nurse Craven. The nurse's red-brown hair and reserved attitude left an impression on him. Barbara said she was unable to handle her husband's scientific work, while Sir William Boyd Carleton showed her a particularly evident tenderness. Car
the first night, late
Allerton’s Sleeping Tablets
Hastings couldn't fall asleep and met [Major Allerton](entity:character-recall-character-major-allerton-0d05212fe758) in the corridor. [Allerton](entity:character-recall-character-allerton-60b09e60755e) gave him a few tablets of Slangberil barbiturate and explained that this barbiturate is dangerous because the effective dose and the toxic dose are very close. Hastings mentioned [Leonard Etherington](entity:character-recall-character-leonard-etherington-380a4865c71c), and All

Franklin’s Ordeal Bean Research
Dr. Franklin explained that he was studying the carabelli bean. This bean has been used for a long time in a ritual to determine guilt or innocence. Different varieties of the bean contain alkaloids with opposite effects; his research may help explain the principle behind the ritual and why the human body can

The First Warning to Judith
Hastings tried to warn Judith to be cautious of Major Alerton, but she was angry because she thought her father was interfering with her. She said she found Major Alerton charming and witty, and insisted that her adult life should be her own decision
soon after Hastings’s warning
The Nurse’s Suspicions
Nurse Crevain told Hastings that Barbara is not particularly intelligent and implied that she used illness to control her husband. She also recounted a murder case she had encountered in her past nursing work and said that the atmosphere at Stiles' house was unsettling because a murder had occurred there. This conversation added
during the first few days
Carrington at Knatton
Carleton took Hasting to Naton Manor and spoke of his deceased wife. She was a heavy drinker and ultimately met a tragic end, leading to the breakdown of their marriage. He recalled that he had once been attracted to a younger woman, but felt too old to bind her to himself
after several days at Styles
Poirot Reframes the Task
Polish criticized Hastings for treating the case as a game of guessing "someone's" identity. He said that what was urgently needed was not who the murderer was, but who was about to die; since "someone's" method would not leave a clear link between him and the victim, it was
during Hastings’s early investigation
Elizabeth’s Hidden Name
In a garden summerhouse, [Elizabeth Cole](entity:character-recall-character-elizabeth-cole-121560239ef8) tells Hastings that Dr Franklin is unhappy because Barbara’s illness stopped him from taking a research post in [Africa](entity:location-recall-location-africa-7f6149c69b08). Elizabeth suspects Barbara enjoys being an invalid, while she sympathizes with Franklin’s frustrated ambition.
She then reveals that her real name is Litchfield: she is a daughter of [Matthew Litchfield](entity:character-recall-character-matthew-litchfield-2ff3363ee06c) and sister to Margaret, who confessed to killing their tyrannical father. Elizabeth cannot believe the confession was truly her sister’s act. Her unresolved grief becomes one of the case’s deepest personal threads.
several days after Hastings arrives
The Luttrells’ Public Humiliation
During a garden gathering, George offers drinks to Hastings, Norton, and Carrington, but Daisy intercepts him inside and berates him for giving away stock that should be sold. Her scolding is audible to the men outside, and George emerges visibly diminished.
Norton fills the awkward silence with talk of shooting accidents, and Carrington tells a story about a soldier who shot his brother. The remarks leave George exposed to precisely the humiliation and violent imagery that X can turn into a dangerous impulse.
the same evening as the garden humiliation
Daisy Is Shot
George sees movement near the young fruit trees and fires his rifle, believing he is shooting a rabbit. Daisy, who has been working among the trees, is struck in the shoulder. Hastings rushes to her, while Norton turns pale at the sight of blood and runs to summon medical help.
The wound is not fatal, but the scene appears to reproduce one of Poirot’s earlier cases: a spouse may have shot a bullying partner, whether deliberately or by accident. Hastings briefly suspects George, until Daisy’s tenderness toward her husband in the sickroom reveals their enduring affection.
the night Daisy is shot
The Apparent Accident
[Allerton](entity:character-recall-character-allerton-60b09e60755e) jokes that George may have shot Daisy on purpose, and Carrington also wonders aloud whether the shot was intentional. Poirot listens as Hastings recounts these remarks, then asks who first planted the idea that the shooting might have been deliberate.
That night Hastings recognizes the resemblance to X’s earlier cases: George would have become the obvious suspect, with the event left uncertain between accident and murder. Since George’s shot was real but Daisy was not killed, Hastings realizes X may have staged the circumstances to make another person’s violence appear spontaneous.
after Daisy’s shooting
The Mercy Debate
A conversation about euthanasia turns to whether a person who is suffering can make a sound decision about ending life. Judith argues that a clear-minded loved one may have a duty to decide for the weak, and says that lives unable to contribute to society should be ended painlessly.
Norton challenges her courage, while Carrington grants that he might accept the principle in theory. Judith insists she would take the risk if her motives were selfless. Her convictions give X a precise moral language with which to provoke her, while Hastings hears a frightening echo of her earlier defense of [Margaret Litchfield](entity:character-recall-character-margaret-litchfield-99bb78d54ae0).
after the mercy debate
Norton Warns Hastings
Norton warns Hastings that [Allerton](entity:character-recall-character-allerton-60b09e60755e) has a history of manipulating women, recounting a seduction that ended with a young woman taking her own life. The story intensifies Hastings’s fear that Judith is falling for a dangerous man.
Carrington independently urges Hastings to warn his daughter. The converging advice seems to confirm Hastings’s worst assumptions, but it is in fact part of the psychological pressure that will push him toward an attempted murder of his own.
soon after Norton’s warning
Judith Rejects Her Father
Hastings finds Judith alone and tells her that [Allerton](entity:character-recall-character-allerton-60b09e60755e) is married and can offer no future. Judith says that Allerton is worth everything to her, then erupts when her father urges her to end the attachment, declaring that her private life is none of his business.
Her response leaves Hastings devastated and more convinced that she is in danger. In reality, her anguish concerns her love for Franklin, not Allerton; Norton is exploiting Hastings’s ignorance of her true feelings and her outward flirtation with the major.
the day after Judith’s quarrel with Hastings
The Bird-Watching Telescope
During a walk, Norton spots something through his bird-watching telescope and abruptly withdraws his attention, claiming he mistook the bird. His troubled reaction makes Hastings suspect that he has seen something compromising, though Hastings assumes it concerns Judith and [Allerton](entity:character-recall-character-allerton-60b09e60755e).
Hastings seizes the telescope but sees only a glimpse of white disappearing among trees. Norton refuses to explain, and the incident later becomes crucial: he has witnessed a scene that could threaten the story he is constructing and may expose the people whose emotions he is manipulating.
before June 10
Barbara’s Warning About Franklin
Barbara tells Poirot and Hastings that Franklin’s scientific devotion is so intense that he might experiment on himself with the [Calabar bean](entity:object-recall-object-calabar-8ad76ecfffa2). She recounts how he once risked testing a new gas in a sealed chamber, presenting him as a self-sacrificing man of science.
Her warning sounds like affectionate anxiety, but it prepares the household to regard a future poisoning as an experimental accident. Poirot notices the shift in Barbara’s performance, while Hastings interprets it as another of her changing emotional roles.
June 10, before lunch
The Rainy-Day Unease
On a wet morning, Carrington appears guilty about having over-tired Barbara the day before, while Norton is distracted and eats chocolates absent-mindedly. Franklin and Judith return from the laboratory looking strained; Franklin says he has suddenly found a simpler route through his research.
The scattered observations later acquire ominous weight. The household is tense, and each person’s apparent preoccupation masks a different danger: Barbara’s plan, Norton’s manipulation, and the fragile emotional bond between Judith and Franklin.
June 10, later that afternoon
Marriage and the Unspoken Love
A discussion of divorce reveals Franklin’s conviction that marriage is a responsibility lasting until death, even when affection has failed. Judith is silent, and Hastings begins to suspect a possible bond between her and Norton’s quiet companion Elizabeth, while Carrington’s glance hints that he has noticed something too.
Judith emerges looking grave, and Norton compares her to the biblical Judith who beheaded Holofernes for a supposed public good. The image unsettles her and foreshadows the lethal moral arguments that have already taken root in her mind.
June 10, after dinner
The Poisoned Coffee
Barbara invites the household to her room for coffee. As everyone steps onto the balcony to watch shooting stars, Hastings remains inside with a crossword and turns toward the bookcase to consult Shakespeare. In that moment, the two cups beside the table are left unattended.
Barbara has placed poisoned coffee intended for Franklin; in the confusion, each spouse drinks the other’s cup. Barbara takes the Calabar-bean alkaloids, while Franklin receives the harmless coffee. The poison kills the intended killer instead of her intended victim, turning the planned murder into an apparent suicide or accidental death.
the morning after June 10
Barbara’s Death
Barbara becomes violently ill during the night and dies the following morning. Subsequent medical examination identifies physostigmine poisoning, with other Calabar-bean alkaloids also present.
The death transforms the household’s tensions into a formal murder investigation. Franklin reports that a concentrated solution has been diluted with water in his laboratory, and the question becomes whether Barbara took the poison herself, by accident, or through someone else’s actions.
two days after Barbara’s death
The Inquest’s Suicide Verdict
At the inquest, Franklin explains the missing poison from his laboratory and says Barbara had access to its key. [Nurse Craven](entity:character-recall-character-nurse-craven-145c0d84c9bf) describes Barbara’s past remarks about wanting to end her life, while Carrington and Poirot emphasize her depression and anxiety about hindering Franklin’s career.
Poirot testifies that Barbara came from the laboratory holding a small bottle and appeared startled when she saw him. His evidence helps the jury conclude that she took her own life while temporarily of unsound mind, closing off a public murder inquiry even though Poirot knows she was killed by her own failed plan.
immediately after the inquest
Poirot Confirms Murder
Hastings asks Poirot whether he truly saw Barbara carrying a bottle out of the laboratory. Poirot refuses to clarify, and Hastings realizes that the testimony may have been shaped to secure the suicide verdict rather than establish the truth.
Poirot privately confirms that Barbara was murdered, but says that labeling the death suicide is necessary to protect innocent people from suspicion. He expects the investigation to continue covertly, though Hastings cannot understand why Poirot would deliberately halt the official inquiry.
the days after Barbara’s inquest
The Funeral and Poirot’s Heart
At Barbara’s funeral, a local woman speculates that Franklin may have killed his wife, reminding Hastings how quickly local suspicion attaches itself to a past murder site. Meanwhile Poirot suffers a serious heart attack and refuses further medical consultation.
He tells Hastings that this will be his last case and admits that X’s technique has so far defeated him. Poirot’s urgency grows: his body is failing, and he fears that X may exploit the short time remaining to strike again.
shortly after Barbara’s funeral
Franklin’s New Opportunity
Franklin examines Poirot and bluntly confirms that his heart is failing and that death may come soon. He has little sympathy for the sanctity of life as an absolute principle, arguing that medical work matters because it improves life rather than merely postponing death.
Franklin also reveals that he has been offered the African research post again and will leave in ten days. He admits that Barbara’s death has freed him from a marriage that had long ceased to make either spouse happy, but denies believing that she committed suicide and refuses to pursue the question.
after Barbara’s funeral
Norton’s Ethical Hints
Norton anxiously asks Hastings what a person should do after accidentally seeing something private that might matter to someone else. He gradually admits that he saw something through his telescope but is uncertain whether it is his place to reveal it.
Hastings recognizes that the sighting occurred on the day Norton abruptly lowered his glasses. He urges Norton to consult Poirot, and Poirot reacts with alarm, insisting that Norton must tell no one else and must visit him privately that evening.
the evening before Norton’s death
Carrington Leaves Styles
Carrington tells Hastings he is leaving [Styles](entity:location-recall-location-styles-3971dba4ed9f) for [Knatton](entity:location-recall-location-knatton-03088d77343e) and says the house seems tainted by malign influence. He suspects Franklin may have caused Barbara’s death, though he concedes Franklin would hardly have chosen a poison linked to his own research.
Carrington also reveals that [Nurse Craven](entity:character-recall-character-nurse-craven-145c0d84c9bf) has suggested Franklin might be responsible. Hastings is unsettled by her return to Styles, while [Allerton](entity:character-recall-character-allerton-60b09e60755e) arrives in the midst of a storm and remains an obvious but unexplained suspect in Hastings’s mind.
the evening before Norton’s death
Poirot Prepares for His Death
Poirot warns Hastings that X may try to eliminate him before natural death removes him from the case. He has arranged for Hastings to find clues in his locked dispatch box if he dies, but refuses to explain them in advance because ignorance itself is an advantage.
The phrase “ring down the curtain” leaves Hastings with an undefined dread. Poirot’s preparations suggest that the case is nearing a decisive point, though his friend still does not grasp what the clues will demand of him.
the night before Norton is found dead
Norton Visits Poirot
Norton goes upstairs to speak privately with Poirot, and Hastings prevents Carrington from joining them, explaining that a second visitor would tire the invalid. Hastings returns downstairs, where the evening proceeds with ordinary games despite the recent death.
Carrington later opens a window as thunder gathers, then leaves the room. Hastings goes to bed without checking on Poirot, hoping to escape the oppressive atmosphere of [Styles](entity:location-recall-location-styles-3971dba4ed9f) for a night.
the morning after his visit to Poirot
Norton Found Dead
The next morning Norton fails to answer his door. [George Luttrell](entity:character-recall-character-george-luttrell-8d1a15523070) and others force it open and find him on his bed in his dressing gown, a small pistol in his hand and a bullet hole centered in his forehead. The door is locked, its key in his pocket, and the windows are shuttered.
The scene appears to be an unmistakable suicide, yet Poirot immediately rejects that conclusion. He points out that Hastings identified a man in a dressing gown rather than proving that the figure he saw entering the room was Norton.
immediately after Norton is discovered
Poirot Rejects Suicide
Hastings tells Poirot that he saw Norton enter his room and lock the door. Poirot presses him on the basis of that identification: the checked dressing gown, untidy hair, and limp could all have been imitated, while Norton’s short stature made disguise and substitution conceivable.
Poirot states plainly that Norton did not shoot himself but was deliberately killed. Hastings is left in a maze of implications, failing to see that the only person with the opportunity and the means to stage the locked room is the very detective who has been guiding him.
shortly after Norton’s death
Poirot Dies
Hastings leaves Poirot’s room without recognizing the danger to him. [Curtiss](entity:character-recall-character-curtiss-6c49a8e471c0) later finds Poirot dead, apparently from a heart attack; the amyl nitrite ampoules that might have helped him are missing from beside the bed.
Hastings cannot believe the death was natural, but he has no explanation for who killed Poirot or why. The apparent victory of X over Poirot leaves Hastings alone to take up the investigation and forces him to open the evidence Poirot left behind.
the day of Poirot’s death
The Empty Case Files
Hastings takes [Poirot’s locked dispatch box](entity:object-recall-object-poirot-ab0bb17f104a) and finds that the dossiers on X’s earlier cases have disappeared. Two books remain: a copy of [Othello](entity:object-recall-object-80273ea9c9ff) and a copy of John Ferguson marked at its third act, along with a note directing him to speak to [Georges](entity:character-recall-character-georges-7cbea3b8b3ab).
The clues make little sense to Hastings, who wonders whether they form a code. Their survival in the box suggests that Poirot intended the case to be solved after his death, but Hastings’s grief and confusion prevent him from seeing their plainest implications.
after Poirot’s funeral
Judith Announces Her Marriage
As Hastings and Judith discuss the future, she tells him that she is going to [Africa](entity:location-recall-location-africa-7f6149c69b08) with Franklin—not as his assistant, but as his wife. Hastings is stunned and assumes she must have been involved with [Allerton](entity:character-recall-character-allerton-60b09e60755e), but Judith explains that the flirtation was never serious and that she let her father believe otherwise.
She and Franklin had loved each other but were restrained by his marriage. Barbara’s death has removed that obstacle, and the couple intend to marry and leave for his research post. Hastings’s earlier certainty about Judith and Allerton is exposed as another misreading.
immediately after Judith’s announcement
Hastings Suspects Judith
Judith’s revelation makes Hastings reconsider her earlier speeches about useless lives and the bottle Poirot claimed to have seen. He wonders whether she and Franklin might have been involved in Barbara’s death, and whether Poirot’s entire story about X was a screen to protect her.
The books in the dispatch box sharpen his anxiety: [Othello](entity:object-recall-object-80273ea9c9ff) could be a clue, and Judith’s biblical namesake evokes a woman who kills in the name of public good. Yet these suspicions arise from the same habit of taking appearances at face value that has repeatedly misled him.
four months after Poirot’s death
The Visit to Georges
In [Eastbourne](entity:location-recall-location-eastbourne-80d8303d5797), Hastings visits [Georges](entity:character-recall-character-georges-7cbea3b8b3ab), who denies knowing of any message left for him. The conversation reveals that Poirot—not family necessity—sent Georges away and arranged to pay him while he cared for his father. Georges also clarifies that Poirot wore a wig, not dyed hair.
Hastings realizes that Poirot had deliberately replaced his experienced valet with [Curtiss](entity:character-recall-character-curtiss-6c49a8e471c0), whom Georges considers unintelligent and physically strong. The discovery suggests that Poirot concealed more than a secret suspect: he had been pretending to be helpless, and Curtiss’s employment may have served that deception.
four months after Poirot’s death, in Poirot’s manuscript
The Truth About X
A sealed manuscript from Poirot explains that X was not the direct killer in the earlier cases. Instead, X was [Stephen Norton](entity:character-recall-character-stephen-norton-99e553794a2b), a quiet man who learned to identify people’s private wishes and use suggestion to break their resistance, turning potential impulses into acts that looked like spontaneous crimes.
Norton had influenced the perpetrators in the Etherington, Sharples, Riggs, Bradley, and Litchfield cases, leaving each apparent killer as the only plausible suspect. Poirot describes this as a catalytic method: Norton remained outside the crimes while arranging the psychological conditions that made others commit them.
before Daisy is shot
Norton’s Attack on George
Poirot’s manuscript reconstructs how Norton engineered the scene that led George to fire at Daisy. He humiliated George through the overheard argument, then used shooting stories and reminders of masculine failure to intensify the colonel’s resentment and shame.
When Daisy appeared near the target, George fired but instinctively missed because he still loved her. Norton’s first attempt therefore failed: the shot wounded Daisy but did not kill her, and the spell of suggestion broke once George saw her as his beloved wife rather than his tormentor.
after Daisy’s shooting and before Barbara’s death
Norton Turns Hastings Against Allerton
Norton uses Hastings’s love for Judith, his conventional morality, his fear of [Allerton](entity:character-recall-character-allerton-60b09e60755e), and his grief for his dead wife to make him believe that his daughter is about to be ruined. Carrington’s warning and the true account of Allerton’s past reinforce the pressure, while Hastings mistakes a staged encounter for proof that Judith is yielding to him.
Norton leads Hastings to the summerhouse and lets him overhear a plan for a secret meeting. The woman is [Nurse Craven](entity:character-recall-character-nurse-craven-145c0d84c9bf), not Judith, but Norton ensures Hastings does not see her. Under the accumulated pressure, Hastings decides to poison Allerton, proving that even an honest man can be driven toward murder by a skilled manipulator.
the night before Barbara’s death
Hastings’s Poisoning Plan
Believing [Allerton](entity:character-recall-character-allerton-60b09e60755e) will take Judith to London for a secret encounter, Hastings decides to stop him by tampering with his [Slumberyl](entity:object-recall-object-slumberyl-57f05300a72c). He replaces eight sleeping tablets with aspirin, intending to give Allerton a drink in which the remaining tablets will dissolve.
Hastings takes care to avoid fingerprints and waits for Allerton, convinced that he is protecting his daughter. Poirot secretly watches through the bathroom keyhole, recognizes the danger, and gives Hastings drugged chocolate so that he sleeps through the night and wakes with his murderous intention gone.
the morning after Hastings’s plan
Poirot Explains the Rescue
Hastings confesses his intended poisoning to Poirot and admits that he had nearly committed murder. Poirot explains that the plan would have left evidence against him: the altered tablets, his motive, and witnesses to his anger could have made him appear guilty if [Allerton](entity:character-recall-character-allerton-60b09e60755e) died.
Poirot advises Hastings to trust Judith and not interfere in her life. He also confesses that he fears for her, because Norton has found a vulnerable moral conviction in her belief that useless lives should be ended for the good of others.
June 10, before the evening coffee
Barbara’s Failed Murder Plan
Poirot reconstructs Barbara’s true intention: she planned to poison Franklin with Calabar-bean alkaloids and leave circumstances suggesting that he had experimented on himself. Her earlier talk about suicide and her fears for Franklin had prepared witnesses to accept either explanation.
Barbara hoped that Franklin’s death would free her to marry Carrington, who retained an old tenderness for her and had wealth and status. She moved too quickly and misjudged the coffee arrangement, so the poisoned cup reached her instead of her husband.
the inquest after Barbara’s death
Poirot Conceals the Murder
Poirot says he recognized that Barbara had been poisoned by her own scheme, but he could not prove how the cups had been switched. If the death were treated as murder, suspicion would fall on Franklin or Judith, both innocent of causing it.
He therefore emphasized Barbara’s melancholy and offered the bottle testimony that helped secure a suicide verdict. The act protects the innocent but also prevents the law from discovering the failed murder plot, leaving Norton dissatisfied and free to exploit the unresolved question.
the night before Norton’s death
Norton Threatens to Expose the Truth
Norton realizes that Poirot’s suicide verdict has denied him the spectacle of suspicion and legal turmoil he craves. He considers using his earlier telescope sighting to suggest that Franklin and Judith were involved, reopening the case and placing the couple under suspicion.
Poirot understands that Norton may turn this hint into another weapon and summons him privately. Rather than allow the danger to reach Judith or Franklin, Poirot decides that Norton must be stopped by a means the law cannot provide.
the night before Norton is found dead
Poirot Kills Norton
Poirot tells Norton that he has identified him as X and intends to execute him. Norton responds with a smirk, treating the threat as another entertaining game. Poirot gives him drugged chocolate; because Norton has no tolerance to the sleeping pills, he falls unconscious while Poirot’s own long-term use makes the same dose less effective.
Poirot uses his wheelchair to move Norton to his room, dresses in Norton’s checked gown and disguises himself as the short, limping bird-watcher. He lets Hastings see the figure enter Norton’s room, then returns, shoots Norton in the forehead, places the key in his pocket, and locks the room with a duplicate key.
the morning after Poirot kills Norton
The Staged Suicide
Norton is found in a locked room with the pistol in his hand, and the death is ruled a suicide despite the exact central wound. Poirot has deliberately staged the scene to resemble one of Norton’s own perfect crimes, while Hastings’s supposed eyewitness account supplies the false confirmation that the dead man was Norton.
Poirot’s manuscript later identifies the clues Hastings could have followed: the duplicate key, Poirot’s unexplained room change, his feigned incapacity, the missing valet, his height and limp, and the centered bullet wound. The detective has left enough evidence to expose himself, choosing to make the truth discoverable rather than stage an irreproachable murder.
four months after Poirot’s death
Poirot’s Final Confession
Poirot’s manuscript admits that he murdered Norton because Norton would continue manipulating people into killing, and because the law could not convict him for crimes he had engineered without directly committing. Poirot remains uncertain whether his action was justified, describing himself as both the law and a man who has violated his own lifelong refusal of murder.
He says his time was short and that he moved his amyl nitrite ampoules away from his bed, leaving his fate to God. His last words to Hastings are a farewell to their partnership, which began and ends at [Styles](entity:location-recall-location-styles-3971dba4ed9f).
in Poirot’s final manuscript
Elizabeth’s Sister Cleared
Poirot explains that Norton also manipulated [Margaret Litchfield](entity:character-recall-character-margaret-litchfield-99bb78d54ae0) into confessing to their father’s murder, making her appear to have acted from compassion and courage. Elizabeth has carried the belief that her sister was either a murderess or insane, and Poirot urges Hastings to tell her that Norton was the true cause of the tragedy.
The revelation transforms Elizabeth’s family history and offers her a chance to stop treating herself as tainted by her sister’s supposed crime. Poirot asks Hastings to find her and help restore the future she has denied herself.
the final lines of Hastings’s account
The Brand of Cain
Hastings finishes Poirot’s manuscript and finally understands that he should have recognized the truth from the perfectly centered bullet wound in Norton’s forehead. The mark recalls the brand of Cain, a sign of guilt that Hastings had seen without interpreting.
The realization confirms Poirot’s confession and leaves Hastings grieving the friend who both saved him from becoming a murderer and died after becoming one himself. Their first and last hunt has ended, but Hastings is left with the task of carrying Poirot’s truth to Elizabeth.
