A young woman wakes in a strange bed. A sickly light filters through a metal grille. Doctor Maynard Straker steps into the room, and speaks. 'Have no fear, Miss Ashton. I am entirely at your service.' This, however, is not her name. And she should not be here - in the Asylum. She is Miss Georgina Ferrars, and she can prove it. But when Dr Straker sends a telegram to her uncle in London, the reply is swift: GEORGINA FERRARS HERE STOP YOUR PATIENT MUST BE IMPOSTER STOP. Madness? Mistaken identity? Or are there more malevolent forces at work?
