Here lies Fanny Lynes, whose whispers from beyond the grave set London alight with scandal. Here swings Mary Bateman, who lived a life of solace and lies - and died a prophetess and murderer. Here stands Mary Willcocks. Or is it Anne Burgess? Or perhaps Princess Caraboo, from the distant island of Javasu?A ghost.A witch. A princess. This is a story of those who lie. But also of those who choose to believe them.
