From the writer whom bestselling author Nelson DeMille called "one of the best, smartest, and most accomplished writers in the country" comes two spellbinding suspense novels featuring symbologist Robert Langdon. The Da Vinci Code. 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 gifted French cryptologist, Sophie Neveu, sort through the bizarre riddles, they are stunned to discover a trail of clues hidden in the works of Leonardo Da Vinci—clues visible for all to see yet ingeniously disguised by the painter. The stakes are raised when Langdon discovers that the curator was involved in the Priory of Sion, a secret society whose members included Sir Isaac Newton, Botticelli, Victor Hugo, and Da Vinci, among others. Langdon suspects that he and Sophie are on the hunt for a breathtaking historical secret, one that has proven through the centuries to be as enlightening as it is dangerous. The Lost Symbol. When Harry Langdon is summoned unexpectedly to deliver an evening lecture in the US Capitol building, the night takes a bizarre turn only minutes after his arrival. A disturbing object—artfully encoded with five symbols—is discovered in the building and Langdon recognizes it as an ancient invitation . . . one meant to usher its recipient into a long-lost world of esoteric wisdom. When Langdon's beloved mentor, Peter Solomon—a prominent Mason and philanthropist—is kidnapped, Langdon realizes that his only hope for saving his friend is to accept this mystical invitation and follow where it leads him—into a clandestine world of Masonic secrets, hidden history, and never-before-seen locations, all of which seem to be dragging him toward a single, inconceivable truth.
