What are the main countries in Agatha Christie novels?

While Agatha Christie wrote about many countries, her novels are most heavily set in England. This is where she herself lived and where many of her most famous characters reside, like Hercule Poirot, Miss Marple, and Tommy and Tuppence Beresford.

However, she also explores other locations:

* France: Christie set many of her mysteries in France, particularly in the French Riviera, a setting that appears frequently in her Poirot stories.

* Belgium: Poirot's origins are in Belgium, and his Belgian identity is a key part of his character.

* Egypt: Christie has written several novels set in Egypt, including "Death on the Nile" and "Appointment with Death."

* Iraq: "Murder in Mesopotamia" is set in the archaeological digs of ancient Mesopotamia, which Christie depicts with accuracy and detail.

* Scotland: The novel "The Big Four" features the Scottish Highlands as a setting.

* Italy: Italy, especially Venice, figures prominently in several novels, including "The Mystery of the Blue Train."

While England is the most frequent setting, Christie's novels also explore a variety of other countries, showcasing the international intrigue and cultural diversity that she seamlessly incorporated into her mysteries.
