Part 4: “December 25th”
Part 4, Chapter 1 Summary
On Christmas morning, Poirot observes the family in the garden and sees Harry being attentive to Pilar. Magdalene approaches Poirot. She suggests that Pilar is suspicious and says that the young woman picked up something from the floor in Simeon’s room the previous night. Poirot reveals that Simeon had been searching for Pilar for some time, corresponding with officials in Madrid and the Spanish town of Aliquara, where her mother died. Magdalene also hints at a “rather disgraceful” secret concerning Pilar’s father, Juan.
Part 4, Chapter 2 Summary
Sugden joins Poirot on the terrace. He confirms that Horbury’s alibi is solid. He also reports that George’s phone call ended nearly 10 minutes before the murder and that Magdalene never made a call, contradicting both of their statements. When Poirot asked what Pilar picked up, Sugden shows him a small piece of pink rubber cut from a bag and a wooden peg. According to the superintendent, Alfred, Harry, and Lydia have confirmed alibis. The remaining suspects with opportunity are George, Magdalene, Pilar, Stephen, and either David or Hilda (as they provide each other’s alibi and one of them must have been playing the piano). Analyzing motives, Sugden notes that Pilar had a strong financial incentive to keep Simeon alive for a new will, making her an unlikely suspect. He considers George and Magdalene’s financial desperation and David’s deep-seated hatred for his father as strong motives. Poirot suggests that the strong sense of pride that Simeon “transmitted to his sons” may be a factor in his death (176).
Part 4, Chapter 3 Summary
In private, Hilda speaks with Poirot about David’s long-held resentment toward his father over his mother’s death. She says he has been struggling with his mental health ever since her death and that coming to Gorston Hall was a mistake. She insists that while David had the desire to kill his father, he channeled it into playing the “Death March” on the piano and is innocent of the murder. David then joins them, shining with “a carefree radiance” that surprises Poirot (179).
Part 4, Chapter 4 Summary
Lydia finds Poirot and tells him that her husband, Alfred, is still asleep. She gave him a sleeping draught to help him rest after his shock. She expresses disbelief that a family member could be the killer but then admits that it’s predictable given how Simeon treated his relatives. Poirot directs the conversation to her hobby of creating miniature rock gardens in stone sinks on the terrace. After she leaves, Poirot inspects the pebbles in a miniature garden of the Dead Sea and exclaims, “This is a surprise! Now what exactly does this mean?” (182).
Part 4 Analysis
These chapters foreground the theme of The Fragility of Identity and the Performance of Self, illustrating how characters construct narratives to deflect suspicion. Magdalene’s interaction with Poirot is a performance, framing the murder as “so very unEnglish” and using xenophobic stereotypes to cast suspicion on Pilar (161). This strategy is designed to make Magdalene appear harmless while implicating the foreign newcomer. Similarly, Hilda presents a curated narrative about David’s mental health that recasts her husband as a tragic figure rather than a potential murderer.
Meanwhile, the narrative juxtaposes Superintendent Sugden’s empirical logic with Hercule Poirot’s psychological intuition. Sugden represents the methodical police procedural, building his case by eliminating suspects based on alibis, opportunity, and traditional motives. His detailed list of who could and could not have committed the crime is a model of rational deduction, yet it is limited by its reliance on observable facts. Poirot, conversely, focuses on the family’s underlying psychology, asserting that the crime is “a poison that works in the blood—it is intimate—it is deep-seated” (169). He frames the murder as the culmination of generational dysfunction. Where Sugden analyzes timetables, Poirot analyzes character, seeking to understand Simeon as the central instigator of the tragedy. While there will ultimately prove to be more to Sugden’s role and methods than meets the eye, for the moment, the contrast guides the reader along Sugden’s logical path of inquiry while Poirot pursues a deeper truth hidden beneath the characters’ performances.
Central to Poirot’s psychological inquiry is the theme of The Inescapable Burdens of the Past. Hilda’s account of David’s resentment explicitly explores this theme, describing him as a man who “suffered a great hurt mentally at his most susceptible age” and framing his character as a direct product of his father’s cruelty (177). From this perspective, the murder could be interpreted as an act of retributive justice. David’s transformation from a brooding artist to a joyful man appears to confirm this, suggesting a catharsis that makes him a primary suspect. However, this focus on David’s long-held grievances serves as a red herring for the true murderer’s motive, which is similarly rooted in a past injustice inflicted by Simeon.
