On the evening of 3 December 1926, Agatha Christie left her home in Sunningdale, Berkshire, in her Morris Cowley. The next morning, the car was found abandoned, balanced precariously on the edge of a quarry. Ten days later, Agatha was discovered in a hotel in Harrogate, claiming to have lost her memory.

Lucy Worsley delves into this traumatic watershed moment in Agatha's life. She visits the key locations, from the chalk pit where Agatha crashed her car to Abney Hall, the grand house where she took refuge (and which would inspire several of her books). Lucy reveals connections between Agatha's real-life experiences and her novels, and uncovers new evidence about Agatha's mental health and the cutting-edge psychiatric treatment she went on to receive.
