Robert Langdon (abridged)

World-renowned Harvard symbologist Robert Langdon is summoned to a Swiss research facility to analyze a cryptic symbol seared into the chest of a murdered physicist. What he discovers is unimaginable: a deadly vendetta against the Catholic Church by a centuries - old underground organization - the Illuminati.

Harvard symbologist Robert Langdon is summoned to deliver an evening lecture in the U.S. Capitol. Within minutes of his arrival, the night takes a bizarre turn. A disturbing object is discovered in the Capitol Building. The object is an ancient invitation, meant to usher its recipient into a long-lost world of hidden esoteric wisdom. And when Langdon's mentor is kidnapped, Langdon's only hope of saving him is to accept this invitation and follow wherever it leads him.
