Robert Langdon, Professor of Symbolism, is in Paris for professional reasons when he receives an urgent late-night phone call. The elderly curator of the Louvre has been murdered inside the museum and next to his body is a riddle. As Langdon and a talented French cryptographer, Sophie Neveu, try to unravel the strange enigmas, they discover a series of hidden clues in the works of Da Vinci.
Things get even more complicated when Langdon discovers something unexpected: The victim had a connection to the Priory of Sion, a secret organization whose members included, among others, Botticelli, Victor Hugo, and Da Vinci. In a desperate race through Paris and beyond, Langdon and Neveu find themselves facing an unknown and powerful adversary who seems to predict their every move. If they fail to decipher the riddle, the documents of the Priory of Sion will be lost forever.
An exciting book that from the first page to its unpredictable end proves that Dan Brown is a master of storytelling.
