The inspiration behind one of the most successful horror movies of all time! Chris MacNeil-adored film star, divorced single mother-has come to Washington, D.C. to finish a movie. Swept up by the demands of her busy, flourishing career, Chris is blind to the subtle warnings that a dark, malevolent presence has invaded her comfortable townhouse. Powerful and cunning, it is taking possession of Regan, her 12-year-old daughter. Every avenue of help leads to a dead end. Now hope lies only in a doubt-ridden priest and his fragile elder...in a terrifying battle with an obscene, unspeakable evil that must end in victory...or madness and death.Blatty, William Peter is the author of 'Exorcist' with ISBN 9780061007224 and ISBN 0061007226.
