The Da Vinci code is a modern-day publishing phenomenon. With millions of copies in print, it is the most popular adult novel of the 21st Century. In an introductory note author Dan Brown tells us that ""all descriptions of documents and secret rituals...are accurate"". But are they? Now Martin Lunn, an expert historian, reveals the truth behind Brown's research. Non-dogmatic and not out to discredit Dan Brown's Da Vinci Code for religious reasons, as some critics in the past have been, Lunn delivers the one essential reader's guide to this highly controversial novel.
