The Da Vinci Code is a 2003 mystery-detective novel written by Dan Brown. It follows symbologist Robert Langdon and Sophie Neveu as they investigate a murder in Paris's Louvre Museum and discover a battle between the Priory of Sion and Opus Dei over the possibility of Jesus having been married to Mary Magdalene. The title of the novel refers to, among other things, the fact that the murder victim is found in the Grand Gallery of the Louvre, naked and posed like 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. Harvard professor Robert Langdon receives an urgent late-night phone call while on business in Paris: the elderly curator of the Louvre has been brutally murdered inside the museum. Alongside the body, police have found a series of baffling codes. nnAs Langdon and a gifted French cryptologist, Sophie Neveu, begin to sort through the bizarre riddles, they are stunned to find a trail that leads to the works of Leonardo Da Vinci and suggests the answer to a mystery that stretches deep into the vault of history.nnUnless Langdon and Neveu can decipher the labyrinthine code and quickly assemble the pieces of the puzzle, a stunning historical truth will be lost forever.
