Angels & Demons by Dan Brown

When world-renowned Harvard symbologist Robert Langdon is summoned to a Swiss research facility to analyze a mysterious symbol — seared into the chest of a murdered physicist — he discovers evidence of the unimaginable: the resurgence of an ancient secret brotherhood known as the Illuminati… the most powerful underground organization ever to walk the earth. The Illuminati has surfaced from the shadows to carry out the final phase of its legendary vendetta against its most hated enemy… the Catholic Church. Langdon’s worst fears are confirmed on the eve of the Vatican’s holy conclave, when a messenger of the Illuminati announces he has hidden an unstoppable time bomb at the very heart of Vatican City. With the countdown under way, Langdon jets to Rome to join forces with Vittoria Vetra, a beautiful and mysterious Italian scientist, to assist the Vatican in a desperate bid for survival.   from Dan Brown website.

Da Vinci code by Dan Brown

"An ingenious 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, Harvard symbologist Robert Langdon is awakened by a phone call in the dead of the night. The elderly curator of the Louvre has been murdered inside the museum, his body covered in baffling symbols. 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 and yet ingeniously disguised by the painter.

Even more startling, the late curator was involved in the Priory of Sion—a secret society whose members included Sir Isaac Newton, Victor Hugo, and Da Vinci—and he guarded a breathtaking historical secret. Unless Langdon and Neveu can decipher the labyrinthine puzzle—while avoiding the faceless adversary who shadows their every move—the explosive, ancient truth will be lost forever" from goodreads
