The Da Vinci Code

Jacques Saunière, Louvre curator and grand master of the Priory of Sion, is killed by the monk Silas, who works for the Teacher. Before dying, he leaves clues for his granddaughter, cryptologist Sophie Neveu, along with Langdon's name. The two flee Captain Fache, pull a cryptex out of a bank and seek out Grail scholar Leigh Teabing. At Westminster Abbey, Teabing is revealed as the Teacher and arrested; Silas dies after accidentally wounding Bishop Aringarosa. At Rosslyn, Sophie finds her brother and grandmother and learns she descends from Jesus and Mary Magdalene. Langdon works out that the Grail lies beneath the Louvre's inverted pyramid.
