Out of the mists of Victoria's England, a diabolical evil has emerged with only one purpose - vengeance.Following a bloody London seance and in the aftermath of a terrifying supernatural contact, a good doctor finds himself the target of malevolence born of the darkest nightmares. But with stalwart companions by his side - including an extraordinarily intrepid investigator - he seeks to expose a dastardly band of nefarious criminals and a chilling conspiracy aimed at the heart of England's future... and instead unearths a crime far more horrible than murder and an experience beyond the limits of imagination.
