When one of the two men is murdered, Dr. Gideon Fell finds himself facing one of the most challenging cases of his career. To solve it, he'll have to confront a series of bizarre and chilling phenomena, diving deep into the realm of the occult and brushing up against witchcraft, magic to solve a seemingly impossible crime. -- adapted from jacket
