Christie wrote 66 detective novels over 55 years. These are the ones to read — starting with the essentials and moving to the underrated gems most readers miss.
Agatha Christie is the best-selling fiction writer of all time — only outsold by Shakespeare and the Bible. She wrote 66 detective novels, 14 short story collections, and the longest-running play in history. The quality across 55 years of writing is remarkably consistent; the worst Christie is still more skillfully plotted than most mystery novels.
The challenge is where to start. This list runs from essential reads to overlooked standalones to late-career surprises — organized by what kind of reader you are.
Ten strangers are invited to a remote island off the Devon coast. One by one they're killed. No Poirot, no Marple — Christie operating without her usual scaffolding. The best-selling mystery novel ever written: over 100 million copies. The solution is buried so thoroughly in the open that most readers don't see it. If you've never read Christie, this is where you start. If you've read all Christie, this is the one you reread.
Get And Then There Were None →Poirot is on the Orient Express when a passenger is murdered in a locked compartment during a blizzard that has stopped the train. Every passenger had motive and opportunity. The solution is one of the most famous in mystery fiction — and it's famous because it's genuinely surprising and then immediately seems inevitable. Christie plays completely fair. Everything is visible to the reader before the reveal.
Get Murder on the Orient Express →A wealthy man is murdered in his study. Poirot is recently retired and living nearby. The novel caused a controversy on publication that has never entirely settled — the solution breaks what many readers considered an unspoken rule of detective fiction. Christie's response: she played completely fair, every clue is present, and the rule doesn't exist. Still the most debated mystery novel ending in the genre's history.
Get The Murder of Roger Ackroyd →A honeymooning heiress is shot dead on a Nile cruise. Her new husband was seen by multiple witnesses being elsewhere with his former lover at the time. Christie builds an interlocking set of alibis that seem airtight and then dismantles them. The Egyptian setting is rendered with more care than most of her other locations. The best of her travel mysteries.
Get Death on the Nile →Written during WWII and locked in a vault, published only after Christie's death as her final gift to Poirot fans. Poirot is elderly and wheelchair-bound, returned to Styles — the scene of his first case — for a final investigation. Christie saves the most technically audacious solution of her career for the last book. Do not read before reading the other Poirot novels; do not skip it after.
Get Curtain: Poirot's Last Case →A notice in the local newspaper announces that a murder will take place at a specific address at a specific time. Residents attend out of curiosity. The murder happens — but not the one anyone expected. Christie's most complex plot and the best Marple novel. The structure — a murder announced in advance — gives the book a formal elegance that most mystery novels lack.
Get A Murder Is Announced →Based on a real historical incident — a tragic mistake by a fan that Christie renders as a mystery. An American film star visiting an English village; a woman poisoned at a garden party. The solution is emotionally devastating rather than purely clever, which is unusual for Christie. Her most literary Marple novel.
Get The Mirror Crack'd from Side to Side →A man accused of murdering a wealthy widow relies on his wife for his alibi. Christie's most famous short story and the basis for a play that she later adapted herself. The reversal at the end is one of her best. Read the story first; then watch Billy Wilder's 1957 film adaptation, which is one of the great legal thrillers on screen.
Get The Complete Miss Marple (includes short stories) →Christie said this was her personal favourite of all her novels. A patriarch of an eccentric family dies of a supposed heart attack; the family's financial entanglement and history of resentments make everyone a suspect. The solution is one she considered too disturbing to use for decades. No series detective — just Charles Hayward, a returned soldier investigating for personal reasons. The darkest standalone she wrote.
Get Crooked House →Christie's most structurally unusual novel — she begins with the proposition that murders aren't the beginning of a story, they're the end. The novel tracks backwards from the murder to the zero point where it became inevitable. Unusually psychological for Christie; the murderer's planning is revealed in real time alongside the investigation.
Get Towards Zero →A young woman asks Poirot to prove that her mother — convicted of poisoning her father 16 years ago — was innocent. Poirot interviews five witnesses and gets five entirely different accounts of the same events. Christie's most literary Poirot and the one most interested in how memory and self-interest distort testimony. The best Poirot novel that isn't already famous.
Get Five Little Pigs →Poirot on holiday at a seaside resort; a woman who attracts male attention is strangled on the beach. The solution depends on a piece of theatrical thinking that Christie handles with unusual elegance — the reader has all the information needed and the puzzle piece that makes it click is genuinely satisfying. One of the most enjoyable of the middle-period Poirot.
Get Evil Under the Sun →A serial killer sends letters to Poirot announcing upcoming murders — each victim's name and location beginning with the same letter as their place. Christie uses the serial killer premise (unusual for the period) to explore how expectation can be weaponized. The solution subverts the serial killer logic entirely and remains one of her best structural achievements.
Get The ABC Murders →A tyrannical patriarch summons his scattered family for Christmas. He's murdered in a locked room with an enormous quantity of blood. Christie wrote this specifically for her brother-in-law, who complained her mysteries weren't violent enough. The locked-room solution is clever; the family portrait is better. Her best family-dynamics novel.
Get Hercule Poirot's Christmas →Written over the course of 15 years and not published until after her death. Christie writes about her childhood in Devon, her first marriage, the mysterious 11-day disappearance in 1926 (which she refuses to explain), her excavation trips to the Middle East with her second husband archaeologist Max Mallowan, and her views on writing. The disappearance section is everything the reader wants to know and tells them almost nothing. Essential for Christie fans.
