Have you read The Da Vinci Code?
Yes, I am guilty of that too.
That novel seems like a bizarre little offshoot of Foucault’s Pendulum.
The author, Dan Brown, is a character from Foucault’s Pendulum. I invented him. He shares my characters’ fascinations — the world conspiracy of Rosicrucians, Masons, and Jesuits. The role of the Knights Templar. The hermetic secret. The principle that everything is connected. I suspect Dan Brown might not even exist.
