Now, in a world of smartphones and tablets, her work is being targeted at digital audiences with an app telling one of her tales through a social media feed of messages, photos and videos.
Agatha Christie Productions has teamed up with entertainment mobile platform TELL to bring the eponymous Quin and socialite Satterthwaite into a contemporary setting.
The story, in which characters talk to each other via Twitter-like text, images and videos, begins at a country manor party where hostess Lady Laura plans to unveil her new online venture.
But the tone soon darkens when a mysterious Mr Quin takes over Satterthwaite’s live blogging of the event, turning the conversation to the suicide, five years ago, of the guests’ mutual friend.
“All of the characters tell their stories on social media so, you voyeuristically look in at their worlds as the story comes out,” TELL interactive director and producer Kevin Moss said. “We kind of call it an entertainment stream and you literally use your thumb to scroll up and down the timeline.”
