"London, October 1890. Crime scene photographer Sarah Bain is overjoyed to marry her beloved Detective Sergeant Barrett--but the wedding takes a sinister turn when the body of a stabbing victim is discovered in the crypt of the church. Not every newlywed couple begins their marriage with a murder investigation, but Sarah and Barrett, along with their friends Lord Hugh Staunton and Mick O'Reilly, take the case. The dead man is Charles Firth, whose profession is "spirit photography"--photographing the ghosts of the deceased. When Sarah develops the photographs he took in the church, she discovers one with a pale, blurred figure attacking the victim. The city's spiritualist community believes the church is haunted and the figure is a ghost. But Sarah is a skeptic, and she and her friends soon learn that the victim had plenty of enemies in the human world--including a scientist who studies supernatural phenomena, his psychic daughter, and an heiress on a campaign to debunk spiritualism and expose fraudulent mediums. In the tunnels beneath a demolished jail, a ghost-hunting expedition ends with a new murder, and new suspects. While Sarah searches for the truth about both crimes, she travels a dark, twisted path into her own family's sordid history. Her long lost father is the prime suspect in a cold-case murder, and her reunion with him proves that even the most determined skeptic can be haunted by ghosts from the past."-- inside cover
