Possessed: The True Story of an Exorcism in Bloomington, MN

For 40 years, the truth about the exorcism of 14-year-old Robbie Mannheim remained a mystery. Then a priest's diary, hidden in a locked room in the mental ward of a St. Louis hospital, came to light -- a diary written by one of the Jesuit priests who witnessed the bizarre and harrowing events firsthand.
Over the period of several terrifying months, the Mannheim family was caught in a titanic struggle while physicians, psychiatrists, and clergy fought for the soul of their child against a power that identified itself with Satan. In POSSESSED, acclaimed author and journalist Thomas B. Allen reveals what he found in the priest's diary as well as his interviews with witnesses to the exorcism of Robbie Mannheim. The evidence Allen uncovered in his investigations is so shocking, so chilling and so totally credible, it will challenge everything you believe -- or don't believe -- about the forces of good and evil.
