Roger Ackroyd knew that his fiancée poisoned her brutal first husband, and when she’s found dead from a suspected suicide, he suspects that someone had been blackmailing her. Then, while reading the evening post, Roger discovered one last fatal piece of information, but before he could finish reading, someone stabbed him to death, in a murder that forces Poirot out of retirement.

The British Crime Writers’ Association voted this the best crime novel ever, and its twist ending is credited with significantly impacting the crime genre.

4. Death on the Nile

5. The A.B.C. Murders

A serial killer is working his way through the alphabet, plunging all of England into a state of panic.

With every murder, the killer appears to grow more confident, even leaving a trail of deliberate clues to taunt Detective Poirot—but that might just prove to be the killer’s first, and fatal, mistake.

6. The Mysterious Affair at Styles

In Christie’s debut novel, we’re introduced to Detective Hercule Poirot, her famously eccentric protagonist. As a Belgian refugee of WWI, Poirot settles in England, but when his wealthy benefactress is found dead, he must put his skills to the test.

So whodunnit: the victim’s much younger husband, her resentful stepsons, her longtime hired companion, a family friend working as a nurse, or the London poison specialist who happens to be in town?

7. A Murder Is Announced

The local gazette announces: “A murder is announced and will take place on Friday, October 29th, at Little Paddocks at 6.30 p.m.”

Naturally, all the villagers of Chipping Cleghorn are more than a little curious. It must be a practical joke or some kind of hoax… but when the curious locals arrive on time at Little Paddocks, the lights suddenly go out and a gun is fired. Only Miss Marple can unravel it the gruesome crime they discover when the lights come back on.

8. 4:50 from Paddington

In the small instant that two trains run side by side, passenger Elspeth McGillicuddy witnessed a murder.

But with no other witnesses, no suspects, and no case, only Elspeth’s friend, Jane Marple, takes her claims seriously.

To crack the case, Miss Marple asks her friend Lucy Eyelesbarrow to infiltrate the Crackenthorpe family, who appear to be at the heart of the mystery.

9. Five Little Pigs

Caroline Crale was convicted of murdering her cheating husband, but there were five other “little pigs” who could have been the culprit: Philip Blake , who went to market; Meredith Blake (who stayed at home; Elsa Greer, who had her roast beef; Cecilia Williams, who had none; and Angela Warren, who cried all the way home.

Sixteen years after the crime, Caroline’s daughter discovers her mother’s posthumous letter that proves her innocence, and asks Hercule Poirot to reopen the case.

10. Evil Under the Sun

Just when Poirot thought he could take a vacation, he arrives at a beach in Devon—only to find a murdered woman among the sunbathers.

Poirot had sensed sexual tension in the air ever since Arlena Stuart arrived, but he suspects that this crime of passion conceals something much more sinister.
