Honestly, trying to tackle Agatha Christie in order is a bit of a nightmare if you’re a completionist. You look at that bibliography and it’s basically a mountain of corpses, poisoned tea, and suspicious vicars. Over 80 books. 66 detective novels. Short stories scattered like buckshot across a century.
If you just grab a random paperback at an airport, you’re probably fine. But there is a "correct" way to do it if you want to see the Queen of Crime actually evolve.
People always ask: should I read by publication date or by character?
Most fans will tell you to go by publication. Why? Because Agatha was a product of her time. If you jump from a 1920s Poirot to a 1970s Poirot, the "vibe" shift will give you whiplash. The world changes around him. The technology, the slang, the way people treat "foreigners"—it all shifts.
The Hercule Poirot Problem
Poirot is the big one. He’s the ego. The mustache. The "little grey cells."
He appears in 33 novels and over 50 short stories. If you want to follow Agatha Christie in order specifically for Poirot, you have to start with The Mysterious Affair at Styles (1920). It’s her debut. She wrote it on a bet with her sister, Madge.
Funny thing is, Agatha ended up hating him.
By the 1960s, she was calling him a "detestable, bombastic, tiresome, ego-centric little creep." But the public loved him, so she kept him alive. Except she didn't—technically. She actually wrote his final book, Curtain, during World War II and locked it in a bank vault for decades. She wanted to make sure he had an ending in case she didn't survive the Blitz.

If you’re reading for the "plot" of Poirot’s life, here is the basic trajectory:
- The Early Years: The Mysterious Affair at Styles (1920) through The Murder of Roger Ackroyd (1926). This is where he establishes his legend. Roger Ackroyd is the one that famously "broke" the rules of detective fiction.
- The Golden Era: This is the 1930s. Murder on the Orient Express (1934), The A.B.C. Murders (1936), and Death on the Nile (1937). If you only read three books, these are they.
- The Later Years: Things get darker. More psychological. Five Little Pigs (1942) is a masterpiece of "cold case" storytelling.
- The End: Curtain (1975). Do not read this first. It will ruin everything. It’s the only book that actually needs to be read in its specific place.
Miss Marple and the Village Vibe
Jane Marple is the opposite of Poirot. She’s not a professional. She’s a "fluffy" old lady who knits and notices things.
She first appeared in short stories (later collected in The Thirteen Problems), but her first novel was The Murder at the Vicarage in 1930.
Reading Marple Agatha Christie in order is much easier because there are only 12 novels. They don’t really have a strict "timeline" in the sense that Marple doesn't change much, though the world of St. Mary Mead definitely gets more modern (and more depressing) as the decades pass.
One weird quirk? Sleeping Murder.
Just like Curtain, Agatha wrote this one early (around 1940) and sat on it. It wasn't published until 1976, after she died.
The "Secret" Books You’re Missing
Everyone knows the detectives, but the "standalone" books are often where Christie was most creative.

Take And Then There Were None (1939). No Poirot. No Marple. Just ten people on an island dying one by one. It’s the best-selling crime novel of all time. Period.
Then there are the "Mary Westmacott" books.
Agatha wrote six novels under this pseudonym. They aren't mysteries. They are "bittersweet" stories about human relationships. She kept the secret for 20 years. One of them, Absent in the Spring, she famously wrote in a single weekend. It’s basically a psychological breakdown in book form.
How to Actually Start
If you're staring at a shelf and feeling overwhelmed, don't just start at 1920.
The early books can be a bit... stiff. Agatha was still finding her voice. If you want the "expert" recommendation for a first-timer, here is the non-linear path to getting hooked:
- And Then There Were None: To see how she handles suspense.
- The Murder of Roger Ackroyd: To see how she plays with the reader.
- A Murder is Announced: The quintessential Miss Marple.
- Death on the Nile: High-stakes Poirot.
Once you’ve done those, then go back and do the full Agatha Christie in order publication list.
The Publication Order (The "Big" List)
If you really want to be a purist, here is how the first few decades looked. You can see the sheer volume of work she was cranking out.

- The Mysterious Affair at Styles (1920) - Poirot starts here.
- The Secret Adversary (1922) - Introduces Tommy and Tuppence (the bickering spy couple).
- The Murder on the Links (1923) - More Poirot.
- The Man in the Brown Suit (1924) - More of an adventure/thriller.
- The Secret of Chimneys (1925) - Introduces Superintendent Battle.
- The Murder of Roger Ackroyd (1926) - The game-changer.
- The Mystery of the Blue Train (1928) - She hated writing this one. She was going through a divorce and the death of her mother.
- The Murder at the Vicarage (1930) - Marple arrives.
She didn't stop. Through the 40s and 50s, she was a machine. Even when she was out in the Middle East on archaeological digs with her second husband, Max Mallowan, she was writing. She used those settings for Murder in Mesopotamia and Appointment with Death.
What Most People Miss
People forget she was a pharmacist.
During both World Wars, she worked in hospital dispensaries. This is why her use of poison is so terrifyingly accurate. She didn't just guess; she knew the dosages. She knew how someone would look if they were dying of arsenic vs. strychnine.
In The Pale Horse, her description of thallium poisoning was so accurate it actually helped doctors recognize the symptoms in real-life cases decades later. That’s not just "storytelling." That’s expertise.
Actionable Next Steps for Your Reading List
- Pick Your Sleuth: If you like eccentric logic, go Poirot. If you like village gossip and human nature, go Marple. If you like 1920s "bright young things" and spy capers, start with Tommy and Tuppence (The Secret Adversary).
- Avoid the "Final" Books: Do not touch Curtain or Sleeping Murder until you have at least 10 other books under your belt. They are the "goodbyes."
- Check the Short Stories: Don't sleep on The Labours of Hercules. It’s a collection of 12 Poirot stories where he tries to mimic the mythological labors. It's clever, short, and punchy.
- Look for Alternative Titles: US and UK editions often have different names. Ten Little Indians or Ten Little Niggers (the original, now-deleted title) is now And Then There Were None. Murder in the Calais Coach is Murder on the Orient Express. Don't accidentally buy the same book twice!
The best way to enjoy Agatha Christie in order is to not be too precious about it. Jump in. Get confused. Suspect the person who seems the most innocent. You'll still probably be wrong. That’s the fun of it.
Start by picking up a copy of The Mysterious Affair at Styles and see if you can spot the clues for the "big reveal" before the final chapter. Most people can't.
