After losing the family fortune to a fraudulent psychic, inventor Henry Strauss is determined to bring the otherworld under control through the application of science. All he needs is a genuine haunting to prove his Electro-Séance will work. A letter from wealthy industrialist Dominic Gladfield seems the answer to his prayers. Gladfield’s proposition: a contest pitting science against spiritualism, with a hefty prize for the winner. The contest takes Henry to Reyhome Castle, the site of a series of brutal murders decades earlier. There he meets his rival for the prize, the dangerously appealing Vincent Night. Vincent is handsome, charming…and determined to get Henry into bed. Henry can’t afford to fall for a spirit medium, let alone the competition. But nothing in the haunted mansion is quite as it seems, and soon winning the contest is the least of Henry’s concerns. For the evil stalking the halls of Reyhome Castle wants to claim not just Henry and Vincent’s lives, but their very souls.
