Robert Langdon #3
The Lost Symbol
In 1991, a document was locked in the safe of the director of the CIA. The document is still there today. Its cryptic text includes references to an ancient portal and an unknown location underground. The document also contains the phrase 'It's buried out there somewhere.' All organizations in this novel exist, including the Freemasons, the Invisible College, the Office of Security, the SMSC, and the Institute of Noetic Sciences. All rituals, science, artwork, and monuments in this novel are real.
