A mind-bending code hidden in the works of Leonardo da Vinci. A desperate race through the cathedrals and castles of Europe. An astonishing truth concealed for centuries . . . unveiled at last. While in Paris on business, Harvard symbologist Robert Langdon receives an urgent late-night phone call. The elderly curator of the Louvre has been murdered inside the museum, a baffling cipher found near the body. As Langdon and a gifted French cryptologist, Sophie Neveu, sort through the bizarre riddles, they are stunned to discover a trail of clues hidden in the works of Da Vinci—clues visible for all to see and yet ingeniously disguised by the painter.
