In Mission 117 we explore the real case of demonic possession behind William Peter Blatty’s horror masterpiece, The Exorcist. Author and researcher Thomas B. Allen obtained a copy of the priest’s diary that was kept during the 1949 exorcism of a boy dubbed “Robbie Doe” that reads like a horror novel. Allen used that diary to write his book: Possessed. We discuss what happened, how it differs from the famous movie, and what happened to Robbie Doe after his exorcisms. We also apologize for the poor audio quality on this mission–the Mother Ship must have hit a solar storm that interfered with the transmission. Don’t miss UFOs over Denver in the news and Dr. Dreck’s own possession!
