Lucy investigates the return of Sherlock. Doyle began the Edwardian age delighting in all it had to offer, but as the First World War approached, Lucy finds that the darkness of the later stories mirrored the reality of Doyle's life. After the loss of his eldest son, he became an evangelist for spiritualism and his star declined after a public spat with a very famous magician. Sherlock Holmes, in contrast, found a life beyond his author, on stage and screen.
