The Demonologist by Gerald Brittle

If you think ghosts are only responsible for hauntings, think again. The Demonologist reveals the grave religious process behind supernatural events and how it can happen to you. Used as a text in seminaries and classrooms, this is one book you can’t put down. Illustrated with photos of phenomena in progress from the Warrens’ private collection. For over five decades Ed and Lorraine Warren have been known as the world’s most renowned paranormal investigators. Lorraine is a gifted clairvoyant, while Ed is the only non-ordained demonologist recognized by the Catholic Church. Together they have investigated thousands of hauntings in their career.
