Set within the hidden chambers, tunnels, and temples of Washington, D.C., The Lost Symbol accelerates through a startling landscape toward an unthinkable finale. As the story opens, Harvard symbologist Robert Langdon is summoned unexpectedly to deliver an evening lecture in the U.S. Capitol Building. Within minutes of his arrival, however, the night takes a bizarre turn. A disturbing object --artfully encoded with five symbols--is discovered in the Capitol Building.
