Da Vinci Code, Dan Brown's best selling novel, purports to be more than fiction: it claims to be based on fact and scholarly research. Brown wants his readers to believe that he is revealing the long-concealed truth about Jesus, Mary Magdalene, and early Christianity, a truth that he says has been suppressed by the malevolent and conspiratorial forces of the Catholic Church. The novel alleges that there has been throughout history a secret group of true followers of a Gnostic Jesus and his wife, Mary Magdalene, the true "Holy Grail". Almost everything most Christians and non-Christians think they know about Jesus, according to Dan Brown, is completely wrong, the result of Catholic propaganda designed to hide the truth from the world.
