As soon as he arrives at the Capitol in Washington to give a lecture, Robert Langdon is confronted with a strange object on which five symbols are engraved. It is a kind of invitation from ancient times, and the recipient is inevitably led to a world of occult and inner wisdom, long lost.
When Peter Solomon falls victim to kidnapping, Langdon realizes that the only way to save his friend and mentor is to accept the invitation-challenge of the object, to break the code and follow the clues to the end. Thus, he soon becomes entangled in a labyrinth of corridors, hidden temples, and unseen crypts beneath Washington. In this dark and dangerous universe, the unfathomable secrets of the Masons reign, and Langdon's revelations lead to an unimaginable and ruthless truth.
Mysterious legends, enigmatic codes, symbols of concealment, and a breathtaking story; this is the explosive cocktail that is The Lost Symbol.
