It is 1942. The world is at war, but inside a quiet room, Hercule Poirot is obsessing over a sixteen-year-old murder. This isn't your typical "body in the library" setup. There are no fresh footprints or cooling corpses. Instead, Five Little Pigs Agatha Christie gave us something far more haunting: a cold case that relies entirely on the fallibility of human memory.
Honestly, it’s her best work. You’ve probably heard people praise And Then There Were None or The Murder of Roger Ackroyd for their shock value. Those are great, sure. But Five Little Pigs—originally published in the US as Murder in Retrospect—is the one that actually sticks in your ribs. It’s a psychological autopsy. It asks a terrifying question: can we ever really trust what we remember from a decade ago?
The Problem With Caroline Crale
The setup is simple but brutal. Carla Lemarchant is about to get married, but she’s carrying a weight. Her mother, Caroline Crale, died in prison after being convicted of poisoning her husband, the famous (and notoriously unfaithful) painter Amyas Crale. Carla has a letter from her mother, written on her deathbed, swearing she was innocent.
Carla believes her. Of course she does. But Poirot isn't interested in a daughter's intuition. He wants the truth.
He decides to interview the five people who were at the house the day Amyas died. He calls them the "five little pigs." These aren't just suspects; they are living repositories of a single, tragic afternoon. The brilliance of Five Little Pigs Agatha Christie lies in how these five accounts differ. It’s not that people are necessarily lying (though some are); it’s that they saw what they wanted to see.
Who Were the Five Little Pigs?
The suspects are a messy, tangled group. Philip Blake was Amyas’s best friend, a stockbroker who hated Caroline. Then there’s Meredith Blake, Philip’s brother, an amateur herbalist who provided the poison—Coniine—unintentionally. Elsa Greer is the young, predatory mistress who was posing for Amyas's final masterpiece. Angela Warren, Caroline’s younger half-sister, was a disfigured teenager at the time. Finally, we have Miss Williams, the stern governess.
They all have reasons to remember things differently.
Philip's memory is colored by his hidden jealousy. Meredith is clouded by his own indecisiveness. Elsa is driven by a possessive, all-consuming passion. When Poirot asks them to write down their accounts of the murder sixteen years later, the discrepancies are tiny but massive. One person remembers Caroline wiping a beer bottle. Another remembers her looking calm. A third swears she was distraught.

This is where Christie shines as a writer, not just a plotter. She captures the way a decade of resentment or guilt can reshape a memory. It’s basically the "Rashomon effect" before that was even a common term in Western pop culture.
The Science of the "Cold Case" Technique
Agatha Christie was often criticized for her "cardboard" characters. Critics like Edmund Wilson famously asked "Who cares who killed Roger Ackroyd?" implying her books were just puzzles without souls.
Five Little Pigs proves them wrong.
The character of Amyas Crale is a triumph of indirect characterization. He’s dead before the book even starts, yet he is the most vivid person in the story. He’s selfish, brilliant, and cruel. He loves his wife, but he loves his art more. He’s willing to destroy his domestic peace to capture the perfect light on Elsa Greer’s face.
You feel the heat of that summer day at Alderbury. You feel the tension in the garden. Christie uses the "closed circle" trope, but by moving it into the past, she removes the physical clues. There’s no magnifying glass needed here. Poirot sits in a chair and listens. He’s looking for the psychological flaw—the one detail that doesn't fit the personality of the person described.
Why the Ending Still Hits Like a Freight Train
If you haven't read it, I won't spoil the identity of the killer. But I will say this: the resolution of Five Little Pigs Agatha Christie is one of the most emotionally devastating endings she ever wrote.
Usually, when Poirot solves a case, there’s a sense of justice or at least order restored. Here, the victory is hollow. The truth comes too late to save Caroline. It comes too late to mend the lives of the survivors. It’s a story about the permanence of loss.

Interestingly, the 2003 TV adaptation starring David Suchet—which is widely considered the definitive version—leans even harder into this melancholy. It changes the ending slightly to make it even more tragic, highlighting the futility of Poirot’s brilliance. He solves the puzzle, but he can't fix the tragedy.
What Most People Miss About the Coniine
Let’s talk about the poison. Coniine is derived from hemlock. It’s what killed Socrates. In the book, Amyas is drinking beer while painting. The poison is added to his glass.
The cleverness isn't in how the poison was administered, but in the timing. Christie understood pharmacology better than most mystery writers of her era, thanks to her time working in a dispensary during World War I. She knew that Coniine causes a gradual paralysis. The symptoms had to match the timeline of the witnesses' movements.
People often get hung up on the "how," but the "why" is where the clues are hidden. Look at the painting Amyas was working on. It’s described as a masterpiece of a girl sitting on a wall, looking "bold and triumphant." That painting is the ultimate piece of evidence. It’s a frozen moment of emotion that contradicts the verbal testimony of the witnesses.
Actionable Insights for Mystery Lovers and Writers
If you’re looking to get the most out of Five Little Pigs Agatha Christie, or if you're a writer trying to understand her genius, here is how to approach this specific text:
- Read for the Gaps: Don't just look at what the suspects say. Look at what they omit. Each written account in the book has a "blind spot" that corresponds to that character's specific ego or trauma.
- Study the Indirect Characterization: Notice how we learn about Amyas through five different lenses. It's a masterclass in building a character without them ever speaking a line of dialogue in the present tense.
- Contrast the Versions: If you have the time, watch the 2003 Poirot episode right after reading. The adaptation makes a few key changes to the "pigs" (specifically the relationship between Philip and Amyas) that actually modernizes the psychological stakes in a fascinating way.
- Check the Title's Symbolism: The nursery rhyme isn't just a gimmick. Each "pig" represents a specific reaction to the crime: going to market (seeking profit/success), staying home (avoiding life), eating roast beef (indulgence), having none (deprivation), and crying "wee wee wee" (guilt/grief).
The real power of this novel isn't the "who done it." It's the "who lived it."
To truly appreciate the depth of this work, focus on the theme of sacrifice. Almost every character in the book thinks they are sacrificing something for someone else, but their "noble" lies are what ultimately led to a woman's death and a man's murder. It’s a messy, human, and deeply flawed set of circumstances that Poirot has to untangle.

Pick up a copy and pay attention to the descriptions of the weather. The heat of that long-ago summer is almost a character itself, baking the resentment into the soil of Alderbury until it’s hard as stone. Poirot doesn't just dig up the truth; he has to break the hearts of the living to get to it. That's why we’re still talking about it eighty years later.
For those interested in the historical context, Christie wrote this during the height of the Blitz. The nostalgia for a "lost" Edwardian/Interwar era is palpable. It’s a book written by someone watching her world crumble, looking back at a time that seemed simpler but was, in reality, just as dark. This adds a layer of genuine grief to the prose that you don't find in her earlier, more "game-like" mysteries.
Investigate the legal reality of the time as well. The fact that Caroline was executed (or died in prison shortly after conviction) reflects the harsh finality of the British legal system before the abolition of the death penalty. There were no DNA tests. There were no appeals based on new forensics. There was only the word of witnesses and the "instinct" of a jury. Poirot’s intervention is the only thing that can challenge that finality.
Next time you’re browsing a bookstore, skip the latest psychological thriller and go back to this. It’s the blueprint. It’s the original "unreliable narrator" feast.
Read the scene where Poirot first meets Elsa Greer, now Lady Dittisham. It is a masterclass in showing how wealth and time can't mask a person's core nature. She is still the girl on the wall, and she is still just as dangerous.
