The Demonologist by Gerald Brittle (1980)
Gerald Brittle’s The Demonologist: The Extraordinary Career of Ed and Lorraine Warren is a gripping dive into the world of paranormal investigation, told through the real-life experiences of one of the most well-known husband-and-wife teams in the field. With a strong narrative voice and a unique interview-style format, Brittle captures the unsettling, chilling nature of the Warrens’ most famous cases—while also managing to educate readers on the theology and thought behind their work.
