博客來哈佛大學的宗教符號學教授羅柏‧蘭登到巴黎出差的深夜，突然接到一通緊急電話，通知他羅浮宮年高德邵的館長遭人謀殺，就在博物館內，屍體旁邊留下了一個令人困惑的密碼。蘭登與法國美女密碼專家 Sophie Neveu 在整理分析謎團的過程中，驚訝地發現在達文西的作品中藏有一連串的線索。這些線索人人可見，卻被畫家巧妙地偽裝，加以隱藏。
蘭登發現一連串令人震驚的關聯：已故的館長是鍚安會的一員--鍚安會是一個真實存在的祕密會社，其中的成員包括牛頓、波提且利、雨果，和達文西等人。至此蘭登發現自己正在追蹤一個石破天驚的歷史大祕密，一個已經埋藏了幾個世紀、既富啟發性又危險的祕密。在這場遍及巴黎的追逐中，蘭登和 Neveu 發現他們是在跟一個始終不露面的幕後主使者鬥智，這個人似乎總是知道他們下一步要做什麼。除非他們可以解開這個錯綜複雜的謎團，否則錫安會的祕密，這個具爆炸力的古老真相，將永遠消失。
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.
The Da Vinci Code heralds the arrival of a new breed of lightening-paced, intelligent thriller…utterly unpredictable right up to its stunning conclusion.
