Mystery writer Agatha Christie is still the world’s best selling author of all time.
Her numerous stories have been adored across the world for decades. Christie’s writing brought us chilling tales and hugely popular detective characters like Hercule Poirot and Miss Marple.
Her mysteries have been adapted into countless TV series and films and later this year Sir Kenneth Branagh’s Death on the Nile is due to hit the big screen.
The latest TV adaptation, The Pale Horse aired on Sunday 9th February on BBC One but the show split viewers as the plot was different from Christie’s original mystery.
If you want to dive into the original tales but don’t know where to start, here’s everything you need to know about Agatha Christie and her novels.
Everything you need to know about Agatha Christie
Although she wrote a few other books too, Agatha Christie is famed for her mystery novels. Some were written as stand-alone, some as series and others were part of short-story collections.
Christie was also a member and president of The Detection Club, a group of British writers who collaboratively wrote mystery books.
In addition to her mystery writing, Christie wrote six other titles outside of the genre under the pseudonym Mary Westmacott (more on this below).
With a keen interest in archaeology (her second husband Sir Max Mallowan was a successful archaeologist), details from her time spent at digs made their way into her fiction writing and prompted her first of three non-fiction books, Come, Tell Me How You Live.
Her second, The Grand Tour: Letters and photographs from the British Empire Expedition, is a non-fiction collection of correspondence from her 1922 travels and the final is her autobiography, published after her death in 1976.
Christie proved she was truly the “Queen of Mystery” when she disappeared herself in December 1926. Her car was found abandoned on the morning of 4th December with her fur coat and driving licence left behind.
Thousands began a manhunt to no avail until, 11 days later, she was found in a hotel in Harrogate. Christie claimed she had a serious case of amnesia (confirmed at the time by psychiatrists) and couldn’t remember where she’d been or what had happened.
Although there have since been various theories about the events of those days (her first husband had recently had an affair and she had checked into the hotel in his lover’s name), Christie’s own disappearance remains her biggest mystery.
How many books did Agatha Christie write?
Agatha Christie wrote 76 books. The first of which was The Mysterious Affair at Styles, featuring Hercule Poirot and was published in 1920.
It took Christie five years to get the book to print, having been rejected by six other publishers previously.
Agatha Christie’s most famous characters
There are many characters, dead and alive, throughout Agatha Christie’s mystery novels but a few stand-out figures have become household names in their own right.
Christie’s earliest and arguably most popular character is Hercule Poirot. Poirot is a Belgian (not French) ex-policeman who employs his services finding the clues to the most complicated cases and coming to the aid of the UK police force.
Superintendent Battle and Inspector Japp are therefore recurring characters in the Poirot novels, who reluctantly rely on his help.
On TV, actor David Suchet’s portrayal of Poirot is probably the most recognisable, with his smart suits and distinctive waxed moustache. Suchet played the character for more than two decades.
Most recently, an older Hercule Poirot was reimagined by John Malkovich in The ABC Murders series on BBC in 2018. In cinemas, he was also played by Sir Kenneth Branagh in Murder on the Orient Express in a star-studded production that came out in 2017. Branagh’s next adaptation, Death on the Nile, is due for release later this year.
The mystery novelist’s other most popular character is Miss Marple. The older, unmarried woman who lives in a village first appeared in short stories before making her way into novels of her own.
Enjoying her cover as little more than a harmless nosy neighbour, Miss Marple uses her understanding of human nature, and different types of personalities, to solve mysteries.
Unusually, the plots don’t follow Miss Marple from the beginning. Instead, she pops up later on, often not until halfway through the story.
There have been two popular UK TV series adaptations of Miss Marple’s mysteries. The first Miss Marple was played by Joan Hickson in the 1980s and 90s before a new series in the 2000s starred Geraldine McEwan. She was also memorably played in four 1960s film adaptations by Margaret Rutherford.
Tommy and Tuppence
Lesser known stars of Agatha Christie’s novels are Tommy and Tuppence, a couple actually named Thomas and Prudence Beresford.
The detective pair form “Young Adventures ltd” which sees them through four novels and a short story collection, resulting in not only their own marriage (at the end of the first book) but a set of twins and a third adopted child.
Their story The Secret Adversary was the first of Christie’s to be made into a foreign feature-length film (and only just the second ever film overall).
The film was a silent picture made in Germany as “Die Abenteuer G.m.b.H” which means “Adventures inc”.
Mary Westmacott was not a book character but in fact a pseudonym that Christie wrote under for her non-mystery novels, of which there were six. She kept her secret for more than 20 years.
The pseudonym was chosen as Mary was Christie’s second name while Westmacott was a family name connected to distant relatives.
The first book published under Mary Westmacott was entitled Giant’s Bread and was published in 1930, a decade into Christie’s career as an author.
According to her granddaughter, Christie put details from her own childhood and experiences of the First World War into the novel.

In 1928, The Coming of Mr Quin was adapted into the first film of Agatha Christie’s work, named The Passing of Mr Quinn. From then, there have been numerous adaptations in almost every incarnation.
The most enduring is arguably David Suchet’s Poirot ITV series, which aired from 1989 until 2013.
The BBC One series Miss Marple starring Joan Hickson ran from 1984 until 1992. Agatha Christie’s Marple on ITV then featured Geraldine McEwan in the title role from 2004 until 2013.
Other TV adaptations have also been popular, for instance The ABC Murders, And Then There Were None and The Curse of Ishtar, while The Pale Horse aired February 2020.
Since the first in the 1920s, there have been other big screen films, most recently revived by Sir Kenneth Branagh. There have also been many theatre productions and radio plays which have drawn from Christie’s work.
There are even a number of video games, anime series and graphic novels based on Agatha Christie’s mysteries.
