Who is Maud Dixon?

Florence Darrow wants to be a writer. Correction: Florence Darrow IS going to be a writer. Fired from her first job in publishing, she jumps at the chance to be assistant to the celebrated Maud Dixon, the anonymous bestselling novelist. The arrangement comes with conditions - high secrecy and living in an isolated house in the countryside. Before long, the two of them are on a research trip to Morocco, to inspire the much-promised second novel. Beach walks, red sunsets and long, whisky-filled evening discussions, win-win, surely? Until Florence wakes up in a hospital, having narrowly survived a car crash. How did it happen - and where is Maud Dixon?
