Da Vinci Code author Dan Brown is being sued, accused of plagiarism in his best-selling book. “Author Lewis Perdue has brought the copyright action at a court in New York, claiming Brown lifted plot material from two of his books – The Da Vinci Legacy and Daughter of God – and used it in The Da Vinci Code, which has sold more than 12 million copies worldwide. But Brown is already suing Perdue for making the plagiarism accusations.”
