兰登无意之中非常震惊地发现，已故的博物馆馆长是峋山隐修会（Priory of Sion）的成员——这是一个真实存在的秘密组织，其成员包括艾撒克·牛顿爵士、波提切利、维克多·雨果与达芬奇，这无疑给他们增加了风险。兰登感觉到他们是在找寻一个石破天惊的历史秘密，这是个数世纪以来就证明了的既能给人启迪又很危险的秘密。在这场足迹遍及巴黎以及伦敦的追逐中，兰登与奈芙发现他们在跟一位始终不露面的幕后操纵者斗智斗勇。他们必须解开这个错综复杂的谜团，否则，峋山隐修会掩盖的秘密，那隐藏了多年的令人震惊的古老真相，将永远消逝在历史的尘埃之中。
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. Near the body, police have found a baffling cipher. While working to solve the enigmatic riddle, Langdon is stunned to discover it leads to a trail of clues hidden in the works of Da Vinci -- clues visible for all to see -- yet ingeniously disguised by the painter.
Langdon joins forces with a gifted French cryptologist, Sophie Neveu, and learns the late curator was involved in the Priory of Sion -- an actual secret society whose members included Sir Isaac Newton, Botticelli, Victor Hugo, and Da Vinci, among others.
In a breathless race through Paris, London, and beyond, Langdon and Neveu match wits with a faceless powerbroker who seems to anticipate their every move. Unless Langdon and Neveu can decipher the labyrinthine puzzle in time, the Priory's ancient secret -- and an explosive historical truth -- will be lost forever.
