Horror writer Stephen King has been accused of defamation and invasion of privacy by a writer who believes that she was the inspiration for Annie Wilkes, the sadistic nurse depicted in King’s best-seller, Misery, according to news site Celebrity Justice.

Anne Hiltner, a 58-year-old freelancer from New Jersey, also claims that a character in Stephen King's TV miniseries "Kingdom Hospital" was taken from her private diaries.

She is demanding $500 million, according to the Sydney Morning Herald, which also notes: "The jumbled lawsuit doesn't detail how King allegedly pilfered the diaries or what was in them."

It is not the first time that Hiltner has sued King. In 1991, courts dismissed a similar suit claiming that Misery was plagiarised from Hiltner’s own writings, and did so again in relation to a later claim that King’s novel Riding the Bullet was taken from a story written by Hiltner’s brother.
