The primary setting is a small, isolated island off the coast of Devon, England. Known as “Soldier Island” (or “Indian Island” in some versions), it is a rocky, barren place accessible only by boat. The island's sole building is a modern mansion perched atop a cliff, designed in a stark modernist style that contrasts sharply with the rugged natural landscape. This remote location serves to cut the characters off from the outside world, heightening the suspense as they find themselves trapped with a murderer in their midst.

Within the mansion, Christie creates a claustrophobic atmosphere as the dwindling group of survivors moves between key locations like the dining room, drawing room, and their individual bedrooms. The author uses the mansion’s layout and the characters' movements to build tension and drive the plot forward. Beyond the island, the novel makes brief references to London and other parts of England, providing context for the characters' backgrounds and the events that brought them to this fateful gathering.

About the Author

Agatha Christie is one of the most beloved mystery writers and the bestselling novelist of all time. During her prolific career spanning more than five decades, she wrote 66 detective novels and 15 short story collections that have sold more than a billion copies in English and another billion in at least 100 other languages worldwide. Her most famous creations–the Belgian detective Hercule Poirot and the spinster sleuth Miss Marple–appeared in dozens of her whodunits and became household names. In addition, her play The Mousetrap set records as the world's longest-running show.

Christie was born in Torquay, a seaside town in Devon, England, in 1890. She began writing detective fiction while working as a nurse during World War I. Her first novel, The Mysterious Affair at Styles, was published in 1920. Beyond her detective fiction, Christie wrote six novels under the pseudonym Mary Westmacott, allowing her to explore more personal and romantic themes. She also chronicled her experiences on archaeological digs with her second husband, Max Mallowan, in her nonfiction work Come, Tell Me How You Live. 

While her public persona was that of the “Queen of Crime," Christie was an intensely private individual. Her personal life took a dramatic turn in 1926 when she mysteriously disappeared for 11 days, sparking a nationwide manhunt. The incident remains one of the most intriguing unsolved mysteries surrounding the author's own life.

Agatha Christie died in Wallingford, Oxfordshire, in 1976, at the age of 85. Nearly 50 years later, her ingenious plots, colorful characters, and masterful misdirection continue to captivate readers and inspire adaptations. Her enduring popularity and influence on the genre are undeniable.
