Level-headed, highly knowledgeable and completely credible, David Devereaux makes his living as an exorcist. He does his work quietly and discreetly in locations ranging from ordinary suburban homes, country pubs and provincial offices to the boardrooms of multinationals and the mansions of household names. He can tell the difference between psychic activity, hauntings by the dead and other entities. He has a long-standing client who has been the target of magical attacks on a regular basis, and he has been able to dissuade the attackers. He has successfully cornered a malevolent ghost, and pushed him across to the other side, and has witnessed violent and terrifying poltergeist activity. In this compelling and fascinating book he recalls his extraordinary experiences in the deadpan, matter-of-fact tone of the unphased professional that he is, approaching the most hair-raising of situations with calm, authority and logic - if often accompanied by a cigarette and a swift whisky.
