A body in a locked room. A snowbound train full of suspects. An idyllic English village where everyone knows everyone else’s business—or thinks they do. Few writers built worlds as instantly recognizable as Agatha Christie, where country houses, luxury cruises, drawing rooms, and quiet streets could all become the stage for murder.

Walk into any bookstore or library's mystery section, and you're bound to have your pick at a wide selection of novels by the great Agatha Christie. She's one of the best-selling and well-known authors in the genre, with 66 detective novels, more than a dozen short story collections, and some of the most recognizable detectives in literary history, all under her name. Agatha Christia novels have been adapted countless times, and her innovative storytelling and characterizations have gone on to shape the genre, even long after her passing.

Taking on Agatha Christie's bibliography may seem daunting for those unfamiliar with her work—but it's a worthwhile endeavor indeed. These seven novels in Agatha Christie's collection—which showcase her writing style, most famous characters, and most mind-bending plots—are the perfect place to start.

The Murder of Roger Ackroyd

1926

Agatha Christie's sixth novel, The Murder of Roger Ackroyd is among her most famous, with many referring to it as Christie's "masterpiece." It is one of the best examples of a plot twist—something that would go on to shape detective novels for decades to come.

The Murder of Roger Ackroyd has all the classic elements central to Christie's identity as an author: a small community, numerous suspects, hidden relationships, financial motives, and an eccentric detective with the ability to perceive the unnoticeable. The novel features Hercule Poirot, one of Christie's most enduring sleuths, as the lead detective, as he is pulled out of his retirement in the English countryside to investigate the murder of wealthy widower Roger Ackroyd.

Nearly a century after publication, its construction remains audacious, and it immediately establishes the kind of narrative games Christie was willing to play with her audience. With countless twists and turns, The Murder of Roger Ackroyd is an excellent entry point to Christie's style and subversion of narrative conventions.

Murder on the Orient Express

1934

If one Agatha Christie novel has become shorthand for the classic whodunit, it may be Murder on the Orient Express.

Published in 1934, the novel strands Poirot on board the luxurious Orient Express when heavy snowfall brings the train to a halt. During the night, an American passenger named Samuel Ratchett is stabbed to death inside his compartment. With the train at a standstill and no apparent way for an outsider to have entered or escaped, it is deduced that the murderer must be among the passengers.

With a dynamic and distinct cast of characters—all suspects in Ratchett's murder—confined in a stalled train in Yugoslavia, Murder on the Orient Express is easily one of Christie's most entertaining novels, and provides an excellent introduction to Poirot's unconventional and psychological sleuthing methods, culminating in one of the most memorable solutions of her career.

Death on the Nile

1937

Death on the Nile takes many of the ingredients Christie used throughout her career and combines them into one of her richest mysteries.

The novel centers on Linnet Ridgeway, a wealthy young woman whose marriage to Simon Doyle has created a bitter romantic triangle with Simon’s former fiancée, Jacqueline de Bellefort. When the newlyweds travel to Egypt for their honeymoon, Jacqueline follows them. Poirot, also traveling in Egypt, quickly becomes concerned by the hostility building between the three. Naturally, a murder follows.

What distinguishes Death on the Nile is how much time Christie spends developing the interpersonal tensions before the central crime even occurs. The mystery grows out of jealousy, resentment, money, love, and pride rather than appearing as an isolated puzzle to be unfurled.

The Egyptian setting also gives the book a sense of scale and glamour that separates it from Christie’s village mysteries and country-house murders. Once the passengers board the steamer Karnak, Christie again creates a closed environment filled with people who have secrets to hide—and who.

A Murder is Announced

1950

Any introduction to Christie must include Miss Marple, and A Murder Is Announced is a quintessential example of this apparently harmless elderly woman turned enduring detective.

Residents of the village of Chipping Cleghorn open their local newspaper to find a notice announcing that a murder will take place at a specific house that evening. They gather at the directed time, assuming the ad is a joke, but when a gunshot follows, the advertised murder becomes real.

Where Poirot frequently travels among wealthy social circles and glamorous destinations, Miss Marple’s mysteries take place in ordinary village life. She solves crimes by comparing behavior to people and incidents she has observed over decades in the quiet community of St. Mary Mead.

People underestimate Miss Marple because of her age and appearance, while she understands that small communities contain the same greed, jealousy, resentment, and cruelty found anywhere else. A Murder Is Announced combines that character insight with one of Christie’s most irresistible premises, making it a strong introduction to one of her most interesting characters.

And Then There Were None

1939

Not every Christie novel revolves around one of her famous detectives, and And Then There Were None proves that Christie was never one to rest on her laurels.

Ten strangers are invited to an isolated island off the English coast, each with a different agenda. Soon after arriving, they discover that their host is missing, with only a recording implicating each guest in another's death left behind. The guests begin to die off one by one, without a brilliant detective like Poirot or Miss Marple to solve the case.

The result is part murder mystery, part psychological thriller, and one of Christie’s most relentless novels. Its premise has been imitated countless times in books, television, movies, and games, but the original remains remarkably singular. For new readers, And Then There Were None demonstrates Christie’s versatility. She could build an intricate puzzle around Poirot’s deductions, but she could just as easily construct a frightening story around paranoia, isolation, and the gradual collapse of trust.

The Secret Adversary

1922

To understand Christie’s full range, new readers should meet Tommy and Tuppence Beresford.

First published in 1922, The Secret Adversary is much less like a traditional Poirot mystery than readers might expect. Childhood friends Tommy Beresford and Prudence “Tuppence” Cowley reunite in post-World War I London, both short on money and eager for excitement. They decide to advertise themselves as young adventurers willing to take on dangerous work and quickly become entangled in a conspiracy involving missing documents, espionage, and a mysterious figure known as Mr. Brown.

More spy thriller than mystery, Tommy and Tuppence introduce a new energy to Christie’s work. They are young, impulsive, and figuring things out as they go, rather than entering the story as methodical detectives like Poirot or Miss Marple.

Cards on the Table

1936

The eccentric Mr. Shaitana invites eight people to dinner. Four are detectives or crime experts: Poirot, mystery novelist Ariadne Oliver, Superintendent Battle, and Colonel Race. The remaining four, Shaitana claims, are people who have previously committed murder and escaped any punishment. After dinner, the group splits into two bridge games. By the end of the evening, Shaitana is dead.

Cards on the Table is simply brilliant. With only four realistic suspects, Christie takes advantage of plot limitations. Instead of identifying which person had the opportunity to kill Shaitana, the investigators must determine what kind of person each suspect is and whether they would be capable of murder.

The book also introduces Ariadne Oliver, Christie’s eccentric detective novelist whose complaints about writing mysteries and dealing with her fictional detective are frequently interpreted as playful commentary on Christie’s own career.
