Though Brown had written about Catholic politics before in "Angels and Demons," "The DaVinci Code" rattled some cages with its inaccuracies, even though it was billed as a work of fiction. Brown's novels tend to meld fiction with reality in a way that seems to convince uninitiated readers (those who may not know the intricacies of the history of the Catholic church or how difficult it is to generate dark matter) of his fiction's veracity, which then forces experts to explain.
Lawsuits have also been filed against Brown for copyright infringement. In 2007 Brown won his case in a court of appeals, and the judge included a secret code in the 71-page ruling.
