The Da Vinci Code The Da Vinci Code is a 2003 mystery-detective novel by Dan Brown. It follows symbologist Robert Langdon and cryptologist Sophie Neveu after a murder in the Louvre Museum in Paris, when they become involved in a battle between the Priory of Sion and Opus Dei over the possibility of Jesus Christ having been a companion to Mary Magdalene. The title of the novel refers, among other things, to the finding of the first murder victim in the Grand Gallery of the Louvre, naked and posed similar to Leonardo da Vinci's famous drawing, the "Vitruvian Man", with a cryptic message written beside his body and a pentacle drawn on his chest in his own blood.
