Blatty was a former Jesuit school valedictorian who conjured a tale of demonic possession and gave millions the fright of their lives with the best-selling novel and Oscar-winning movie.

Blatty's story of a 12-year-old-girl inhabited by a satanic force was published in 1971 and sold more than 10 million copies. The film, starring Linda Blair, came out two years later and its box office topped $400 million worldwide.
