Title: The Lost Symbol
Author: Dan Brown
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.
Yes, all the organizations exist and all the rituals, etc, are real. It is just the details that have been fabricated.
The Lost Symbol does for Freemasonry what The Da Vinci Code did for the Catholic Church.
