What is the setting in book and then there were none?

The setting of Agatha Christie's novel "And Then There Were None" is a remote island off the coast of Devon, England. The island is owned by a mysterious man named U.N. Owen, who has invited ten people to stay there as guests. The guests are all strangers to each other, and they are all accused of having committed murder. As the guests begin to die one by one, they realize that they are being hunted by a killer. The setting of the island is important to the story, as it creates a sense of isolation and claustrophobia. The guests are trapped on the island, and they have no way to escape. This makes them easy prey for the killer.
