Brighton. 1871. Mina Scarletti, a debunker of fraudulent mediums, is consulted by an engaged couple who want the truth behind a twenty year old unsolved family murder before they marry. They need a reliable medium to contact the only person who knows the answer – the victim’s troubled ghost. The most prominent mediums in town are fragile Miss Brendel, who sees visions of both the living and the dead, and strange Mr Castlehouse who invokes the spirits to write messages on slates. Are they frauds or genuine? What is the secret behind Miss Brendel’s mysterious illness? Can Mina uncover the clues to solve a murder? And what is her incorrigible scallywag of a brother up to this time?
