Reading order
Agatha Christie Books in Order
Sixty-six novels, almost no continuity, and three rules that actually matter. Start with the best, not the first.
Updated October 2026 · By Sawyer V.
The short version
You do not have to read Christie in order. Poirot barely ages and almost never refers to earlier cases, so publication order is optional — unlike a modern crime series. Three rules do matter: read Curtain last, read Sleeping Murder last, and read The Murder of Roger Ackroyd before anybody spoils it. Start with The Murder of Roger Ackroyd or And Then There Were None.

How we picked
The six below are entry points rather than a complete list — Christie published sixty-six detective novels and nobody starts by buying them all. Publication dates are first UK book publication, checked against the catalog record for each title and against the publisher's own history where the two disagreed. Where sources disagree on how many novels a detective appears in, we give the range rather than pick a number. We have not read all six.
What we do on every list: read the publisher’s own description rather than a summary of it, check print length and first publication year against library catalog data (last refreshed October 11, 2026), confirm the book is still sold in the format we suggest, and write the match line before the blurb. What we do not do is claim to have read every book here cover to cover. The full method is published, and it is written so anyone can check it.
Why order barely matters here
Modern crime series are built on continuity. The detective's marriage fails, a partner dies, a reveal in book nine depends on what you learned in book four — so you read in order or you ruin it. Our Michael Connelly reading order exists for exactly that reason.
Christie does not work that way. Poirot is introduced as an elderly retired policeman in 1920 and is still working in the 1960s. Hastings comes and goes. Cases are almost never referred back to. There is no arc to spoil, because there is no arc — each novel is a self-contained problem, which is precisely what made them reprintable forever.
- No continuity to protect. Characters do not develop between books in a way a reader needs to track.
- No power creep. The method in the first book is the method in the last: talk to everybody, notice the thing nobody else noticed.
- Uneven quality. The early 1920s thrillers and some late novels are weaker. Reading in order front-loads the worst of them.
- Series overlap is cosmetic. Poirot and Marple never meet, and the handful of recurring side characters require no introduction.
The three rules that do matter
Almost everything about Christie's order is optional. These three are not, and they are the only reason this page needs to exist.
- Read Curtain last. It is Poirot's final case, written during the Second World War and locked away until 1975. Christie's own published reading guidance is explicit about saving it for the end, and reading it early takes something from every Poirot you read afterwards.
- Read Sleeping Murder last, among the Marples. Written in the same wartime period and published in 1976, after Curtain. It is Miss Marple's final case and it belongs at the end of her sequence, not Poirot's.
- Read The Murder of Roger Ackroyd before you are spoiled. No order requirement at all — a pure practical one. It has the most famous solution in the genre and the twist is discussed everywhere. It is worth reading early simply because the clock is running.

Six entry points, by what you want
1. Start here
The Murder of Roger Ackroyd
Agatha Christie
Give this ifthey have never read a Christie and do not know the twist
A retired manufacturer is found stabbed in his study the evening after the woman he was to marry kills herself. The solution is the most famous structural trick in detective fiction and it is played entirely fair — every clue is on the page. It is the best possible first Christie for exactly one reason: you can only read it unspoiled once.
One caveat: Which is also the risk. The twist is discussed openly all over the internet, so read it before somebody hands it to you.

2. The best one
And Then There Were None
Agatha Christie
Give this ifthey want her single greatest novel
Ten strangers are invited to an island off the Devon coast, accused by a recorded voice of killings they were never tried for, and begin to die in the order of a nursery rhyme. No Poirot, no Marple, no series — her best-selling book and the one most often named her best.
One caveat: Published in the UK in 1939 under a title that is now unprintable, which is why early editions carry a name you will not see on a modern cover.

3. Where the order begins
The Mysterious Affair at Styles
Agatha Christie
Give this ifthey want to start at the actual start
A wealthy woman is poisoned at her Essex country house, and a Belgian refugee living in the village turns out to have been a famous detective at home. Poirot's first case, Hastings's first narration, and the book that established the shape Christie would use for fifty years.
One caveat: A first novel, and it shows next to the 1930s books. Read it for the beginning, not the best.

4. The famous one
Murder on the Orient Express
Agatha Christie
Give this ifthey have seen a film and want the book
A train is stopped by snowdrifts in Yugoslavia, a passenger is found stabbed twelve times behind a locked door, and every other person in the carriage has an alibi. The purest closed-circle puzzle she wrote, and the ending is still argued about a century later.
One caveat: Widely adapted and widely spoiled. Serialized in a US magazine in 1933 and published as a book on 1 January 1934, which is why catalog dates for it disagree.

5. The best-plotted Poirot
Death on the Nile
Agatha Christie
Give this ifthey liked Orient Express and want better
An heiress honeymooning on a Nile steamer is shot in her cabin, watched by a boat full of people with motives. The machinery here is more intricate than Orient Express and the setting does more work — it is the Poirot that most rewards rereading once you know.
One caveat: A slow first act. The murder arrives later than modern readers expect.

6. The bloody one
Hercule Poirot's Christmas
Agatha Christie
Give this ifthey think she is too genteel
A tyrannical old man summons the family he has spent decades tormenting, and on Christmas Eve they hear furniture crashing overhead and find his throat cut behind a locked door. Christie wrote it after a relative complained her murders had gone bloodless; the dedication says so outright.
One caveat: The solution turns on a physical trick some readers call a stretch. It is clued.

The series, and which to try first
| Series | Roughly | Starts with | Try instead |
|---|---|---|---|
| Hercule Poirot | 33 novels | The Mysterious Affair at Styles (1920) | The Murder of Roger Ackroyd (1926) |
| Miss Marple | 12 novels | The Murder at the Vicarage (1930) | A Murder Is Announced (1950) |
| Tommy and Tuppence | 4 novels and a collection | The Secret Adversary (1922) | Skip unless you want the lighter ones |
| Standalones | A dozen or so | No order at all | And Then There Were None (1939) |
Dates above are first UK book publication. The practical advice is the fourth column: both detectives are introduced in novels that are not among their best, and starting at the beginning is the most common way people bounce off her.
If you want the tradition rather than the author, the best fair-play mysteries places her among the writers who kept the same promise, and Christmas mysteries covers the December corner of the shelf, which is almost entirely hers and her contemporaries'.
When you run out
Most people who say they have read all of Christie have read six of her, which is worth checking before going looking elsewhere — there are sixty more. But when the backlist really does run out, the thing to match is the promise rather than the detective: every clue on the page, and an answer you could have reached.
Books like Agatha Christie sorts the successors by which element of her they match — the puzzle, the closed circle, the village or the period — and names which modern books keep the fair-play contract and which only put it on the cover.
In audio she is unusually well served, because the amateur-detective voice suits a narrator and most of the catalog exists in several recordings: mystery audiobooks has the shelf.
Two ways to read this list for less
If several books here appeal, a subscription usually beats buying them one at a time — but only for the right kind of reader. Here is who each one actually suits.
Audible Premium Plus
For anyone whose hands are busy
Driving, walking, cooking, cleaning. It converts hours that were never available for reading, which is a bigger effect than any discount. Books bought with a credit stay yours after you cancel — titles from the included catalog do not, and confusing the two is the most common complaint about the service.
See Audible plans and current pricingHow Audible actually works — credits, gifting and what happens when you cancel.
Kindle Unlimited
For fast readers who browse
It pays off from about three ebooks a month, in the genres the catalog covers well — romance, romantasy, cozy mystery, thriller, progression fantasy. It does not pay off if you are waiting on a specific new hardcover, because those are usually not included. Everything is borrowed, not owned.
See Kindle Unlimited terms and pricingIs Kindle Unlimited worth it? — the arithmetic, done on your own reading.
#ad — how we are funded. We print no subscription prices anywhere on this site, because they change and a stale figure sends you to a checkout expecting something that is not there. And if you read in silence in a chair, neither of these is for you — buy the book, or borrow it from your library.
What we would skip
A strict chronological or publication-order read-through
People start one, hit three mediocre 1920s thrillers in a row, and conclude they do not like Agatha Christie. Her output is sixty-six novels across fifty-odd years and the quality is not evenly distributed — the great run is roughly 1926 to 1942, and several early books are adventure stories rather than detection. A modern crime series rewards reading in order because the detective's life is the throughline. Christie's does not: Poirot barely ages across fifty years and almost never mentions a previous case. Read the good ones first, in any order, and keep the three rules below.
Questions people ask
Do I have to read Agatha Christie books in order?
No. Poirot and Marple novels are self-contained, the detectives barely age, and earlier cases are almost never referred to. Three exceptions matter: read Curtain last, read Sleeping Murder last, and read The Murder of Roger Ackroyd before it is spoiled for you.
What is the first Agatha Christie book?
The Mysterious Affair at Styles, published in 1920. It is Poirot's first case, and it is a first novel — most readers are better served starting with The Murder of Roger Ackroyd or And Then There Were None.
Which Agatha Christie book should I read first?
The Murder of Roger Ackroyd, while you are still unspoiled, or And Then There Were None if you would rather have her best book than her most famous trick.
Why must Curtain be read last?
It is Poirot's final case. Christie wrote it during the Second World War and had it held back until 1975, and the published guidance is explicit about saving it for the end. Reading it early takes something from every other Poirot.
How many Agatha Christie books are there?
Sixty-six detective novels and fourteen short story collections. Counts for individual detectives vary by source — Poirot is usually given thirty-three novels, Miss Marple twelve — because collections and adaptations get counted differently.
Do Poirot and Miss Marple ever meet?
No. Christie kept them apart deliberately and said she saw no reason to put them in the same book.
