Enter the labyrinthine world of internationally bestselling author Dan Brown with his first two spellbinding thrillers featuring Robert Langdon:

Angels and Demons
When a groundbreaking scientist is found brutally murdered, world-renowned Harvard professor Robert Langdon is summoned to identify the mysterious symbol seared onto the dead man's chest. His conclusion, that it is the work of the Illuminati, a secret brotherhood presumed long dead, leads him to Rome, where against the backdrop of a papal election, the Illuminati look set to renew their bitter vendetta against their sworn enemy, the Catholic Church.

The Da Vinci Code
Robert Langdon receives an urgent late-night phone call while on business in Paris: the elderly curator of the Louvre has been violently murdered inside the museum. Alongside the body, police have found a series of baffling codes. As Langdon begins to sort through the bizarre riddles, he is stunned to find a trail that leads to the works of Leonardo da Vinci - and suggests the answer to an age-old mystery which will take him into the vaults of history.
