Agatha Christie is the world's most translated author, with her work being available in over 100 languages. And one of her most beloved characters, Miss Marple, is about to be resurrected with the help of 12 contemporary authors. In The Studio talks to two of those writers: Dreda Say Mitchell who specialises in a different type of crime story, the gritty gangster genre, and Kate Mosse, who's known for her historical sagas. They reveal how they rose to the challenge of re-inventing one of the most famous characters in twentieth century fiction.
