Snow. It’s everywhere. It’s the literal and figurative wall that turns a luxury train into a claustrophobic pressure cooker. When Agatha Christie sat down to write the Murder on the Orient Express book, she wasn’t just looking for a clever way to kill a guy in a locked room. She was interested in what happens when the law fails and twelve people decide they’ve had enough. Honestly, if you’ve only seen the movies—whether it’s the 1974 classic with Albert Finney or the mustache-heavy Kenneth Branagh version—you are missing the internal coldness that makes the novel a masterpiece.
The book is tight. It’s lean.
It starts with Hercule Poirot, a man who just wants a decent cup of coffee and a quiet trip home, being forced onto a packed Simplon Orient Express. It’s winter, 1934. The train is weirdly full for the season. You’ve got a Russian Princess, a British Colonel, a high-strung American widow, and a shady businessman named Ratchett. Ratchett knows someone is out for his blood. He tries to hire Poirot. Poirot says no. Why? Because he doesn't like Ratchett's face.
That’s the kind of blunt, human pettiness Christie excels at.
The Lindbergh Connection You Might Have Missed
Most people realize the Murder on the Orient Express book is inspired by a real crime, but the depth of that connection is staggering. In 1932, the kidnapping of Charles Lindbergh’s baby shocked the world. It was a messy, tragic affair that ended in the child’s death despite the ransom being paid. Christie took that raw, global trauma and baked it into the character of Daisy Armstrong.
In the novel, Ratchett isn't just a jerk. He’s Lanfranco Cassetti, the man responsible for the Armstrong kidnapping. He escaped justice on a technicality and fled to Europe with his blood money.
This isn't just "flavor text." It’s the moral engine of the entire story.
Christie was living in Iraq at the time, traveling back and forth on the Orient Express to visit her husband, archaeologist Max Mallowan. She knew the rhythm of the rails. She knew the sound of the wheels. She also knew the feeling of being stranded. In 1931, she was actually stuck on the train for twenty-four hours due to flooding. She used that experience to create the snowdrift near Vinkovci that stops the train—and the world—in its tracks.

Why the Murder on the Orient Express Book Structure Works
The book is divided into three distinct parts: The Facts, The Evidence, and The Hercules Poirot Sits Down and Thinks part. Okay, the last one is technically "The Observations of Hercule Poirot," but you get the idea.
Many modern thrillers try to be too clever. They hide information. Christie doesn't really do that. She lays it all out, but she relies on your own biases to blind you. You see a valet, you think "servant." You see a Princess, you think "fragile." Poirot doesn't do that. He looks at the wounds.
Some wounds are deep. Some are shallow. Some are left-handed, others right-handed.
The Psychology of the Twelve
If you look at the clues—the grease-spotted passport, the pipe cleaner, the scarlet kimono—they feel like a chaotic mess. It’s basically a jigsaw puzzle where the pieces belong to five different boxes. That’s because the crime wasn't the work of a mastermind; it was a communal act of execution.
- There are twelve wounds.
- There are twelve jurors in a standard trial.
This isn't a coincidence. Christie is beating us over the head with the theme of justice versus law. When the train gets stuck in a snowdrift, it creates a vacuum. Inside that vacuum, the rules of the Yugoslavian police don't matter. Only the rules of the Armstrong family matter.
Challenging the "Great Detective" Trope
Poirot is often viewed as this infallible machine of logic. But in the Murder on the Orient Express book, we see him genuinely rattled. He’s faced with a situation where his moral compass spinning. Usually, Poirot catches the killer and hands them over to the cops. End of story.
Here? He offers two solutions.

The first solution is a lie. He suggests a mysterious stranger snuck onto the train, killed Ratchett, and vanished into the snow. It’s a terrible explanation. It makes no sense. The second solution is the truth: everyone did it.
The brilliance of the book's ending is that Poirot—the man who lives for "order and method"—chooses to champion the lie. He decides that because Ratchett was a monster who escaped the law, the people who killed him shouldn't be punished. It’s one of the few times in detective fiction where the detective lets the murderers walk free.
The Legacy of the 1934 Publication
When the book hit shelves in the UK via the Collins Crime Club, it changed how people thought about the "whodunnit." Before this, the killer was always the person you least suspected—usually a lone actor. Christie broke the "Golden Age" rules of detective fiction (specifically those laid out by Ronald Knox) by having a whole group of people collaborate.
It was seen as a "cheat" by some purists.
But readers loved it. The idea that a group of strangers from different walks of life could be united by a single, tragic event resonated in a post-WWI world where grief was a universal language.
Common Misconceptions About the Plot
People often remember the ending but forget the middle. They forget that Poirot spends a massive chunk of the book interviewing people in the dining car. These interviews are a masterclass in character writing.
- The Swedish Missionary: Greta Ohlsson is described as having a "sheep-like" face.
- The Italian Car Salesman: Antonio Foscarelli is loud, bombastic, and a classic Christie stereotype (which she used to hide his real identity).
- The Governess: Mary Debenham is the one who almost gives it away because she’s too cool, too calm.
A lot of readers think the "red kimono" was a real person. It wasn't. It was a plant, a "red herring" designed to make Poirot look for someone who didn't exist. It's a classic bit of stagecraft.

Expert Take: The "Jury" Logic
Critics like Robert Barnard have pointed out that the Murder on the Orient Express book is essentially a "fair play" mystery. All the clues are there. If you count the stabs, you can count the suspects. If you look at the timing of the "cry" from Ratchett's cabin, you realize it was a man who didn't speak French speaking French.
It’s simple. It’s elegant.
But it’s also incredibly dark. Think about the logistics. Twelve people took turns entering a darkened cabin to stab a drugged man. That’s not a "mystery" in the cozy sense; it’s a ritual. It’s a collective exorcism of their grief.
How to Approach the Book Today
If you’re picking up the Murder on the Orient Express book for the first time, or if you’re rereading it after years, look past the "mystery." Look at the social dynamics.
The Orient Express was a microcosm of class. You had the elite and the people who served them. In the book, these class lines are blurred by the crime. The valet and the Princess are equals in the eyes of the "jury." That was a radical idea in 1934.
Actionable Insights for Mystery Lovers
- Read the Lindbergh Case First: To truly appreciate the stakes, spend ten minutes reading about the 1932 kidnapping. The parallels make the ending feel much more earned and much less like a gimmick.
- Watch the 1974 Film After Reading: It’s widely considered the most faithful to the book’s atmosphere, despite the 2017 version having better visuals.
- Track the "Lies": On a second read-through, pay attention to how each character reacts when Poirot mentions the Armstrong family. Their masks slip for just a fraction of a second.
- Check the Timeline: Use a notepad to track the movements of the conductor, Pierre Michel. Once you realize his connection to the victim, the whole house of cards collapses.
The Murder on the Orient Express book remains a cornerstone of literature because it asks a question we still haven't answered: Is killing ever just? Agatha Christie doesn't give us a moral lecture. She just shows us the snow, the train, and twelve people with a knife.
The rest is up to Poirot. And us.
Next Steps for Readers
To get the most out of your experience with Agatha Christie's work, compare Murder on the Orient Express with Death on the Nile. While Orient Express focuses on collective justice and a static environment (the snowdrift), Nile explores individual obsession and a moving landscape. Noticing the contrast in how Poirot handles these different motives will give you a deeper understanding of Christie’s evolution as a writer.
