William Peter Blatty was a senior at Georgetown University in 1949 when he heard the extraordinary story that, more than two decades later, would change his life – and scare the devil out of everyone else.
One of the priests at the university told him about a case from nearby Prince George's County in which a 14-year-old boy seemed to be possessed by a demon. After months of solemn rites of exorcism by Catholic priests, the demon appeared to be expelled.

Blatty went on to sell vacuum cleaners, drive a beer truck and serve in the air force before becoming a comic novelist and a screenwriter in Hollywood. Years later, out of work and out of ideas, he sat down at a typewriter and, as if possessed himself, wrote The Exorcist.
Changing the central character to a 12-year-old girl living in Georgetown, he produced a dark theological thriller that became an international blockbuster when it was published in 1971. The 1973 film version, for which Blatty won an Academy Award for his screenplay, revolutionised the genre of horror movies and, thanks to head-spinning special effects and the acting of young Linda Blair, became a pop-culture phenomenon.

Blatty, 89, died on January 12 at a hospital near his home in Bethesda, Maryland. The cause was multiple myeloma, a form of blood cancer, said his wife, Julie Blatty.
From the beginning, Blatty knew he had something special with The Exorcist.
"I couldn't wait to finish it and become famous," he told People magazine.
"The eyes gleamed fiercely, unblinking," he wrote in one evocative passage about his main character, Regan MacNeil, "and a yellowish saliva dribbled down from a corner of her mouth to her chin. Then her lips stretched taut into a feral grin, into bow-mouthed mockery. 'Well, well, well,' gloated Regan sardonically ... 'So, it's you.' "
A scathing review in Time magazine proved prophetic in a backhanded way: "It is a pretentious, tasteless, abominably written, redundant pastiche of superficial theology, comic-book psychology, Grade C movie dialogue and Grade Z scatology. In short, The Exorcist will be a bestseller and almost certainly a drive-in movie."
When there was an unexpected opening on Dick Cavett's late-night talk show, Blatty was summoned as an emergency guest. He and Cavett ended up discussing demons, exorcism and Catholic theology for 45 minutes.
From that moment on, people couldn't get enough of The Exorcist. It was on bestseller lists for over a year, eventually selling more than 13 million copies in the US alone. It was translated into dozens of languages.
When Blatty sold the film rights, he demanded and received full artistic control as producer. The movie, directed by William Friedkin, was filmed largely in Georgetown. The cast included Max von Sydow, Lee Cobb and Ellen Burstyn, but the breakout star was the 13-year-old Blair as demon-beset Regan MacNeil.
Hollywood makeup master Dick Smith created some of the film's most shocking effects, such as bulging eyes, rotting teeth, projectile vomiting and a head that could rotate 360 degrees. The film's musical theme, Mike Oldfield's eerie Tubular Bells, added a haunting quality of its own.
The Catholic Church generally overlooked the blasphemy in the book and movie, including Blair's unauthorised use of a crucifix and the profane epithets coming from her mouth.
Critics sharpened their knives, often dismissing the film as exploitative drivel. "Appallingly effective on the surface," Gary Arnold wrote in The Washington Post, " The Exorcist is appallingly worthless beneath the surface."
Moviegoers didn't care. The Exorcist broke box office records everywhere it opened and was nominated for 10 Academy Awards. It won two, for Blatty's best adapted screenplay and best sound.
The book and movie also prompted a continuing debate about the validity of exorcism and whether people could in fact become embodiments of the devil in the flesh.
"Nobody's going to expect this to happen here," Blatty told Washingtonian magazine in 2015, "and that's what I was trying to get across: This is not a horror story. This is real. Something really happened here in Washington, DC, with ordinary life buzzing all around."
William Peter Blatty was born on January 7, 1928, in New York, the fifth and youngest child of Lebanese immigrants. He was a toddler when his parents split up, and he was raised by his strong-willed mother, who sold quince jelly on the streets of Manhattan.
After attending a Jesuit high school in Brooklyn, he received a scholarship to Georgetown, graduating in 1950 with a bachelor's degree in English. "Those years at Georgetown were probably the best years of my life," he said in 2015. "Until then, I'd never had a home."
Unable to find a teaching job, Blatty sold vacuum cleaners door to door and drove a beer truck before enlisting in the air force, where his Arabic language skills proved useful. He received a master's degree in English from George Washington University in 1954, then worked for the US Information Agency in Lebanon.
He later found success as a screenwriter, most notably with A Shot in the Dark (1964), one of the slapstick Pink Panther movies directed by Blake Edwards, with Peter Sellers as the hapless Inspector Clouseau.
Blatty wrote screenplays for other films, including What Did You Do in the War, Daddy?(1966) and the espionage musical Darling Lili (1970), both directed by Edwards, before the monumental success of The Exorcist.
Blatty's marriages to Mary Rigard, Elizabeth Gilman and professional tennis player Linda Tuero were dissolved. Survivors include his wife of 33 years, Julie Witbrodt Blatty of Bethesda; and seven children from various marriages.
