The Lost Symbol: (Robert Langdon Book 3)
by Dan Brown
Washington DC: Harvard symbologist Robert Langdon is summoned at the last minute to deliver an evening lecture in the Capitol Building. Within moments of his arrival, however, a disturbing object - gruesomely encoded with five symbols - is discovered at the epicentre of the Rotunda. It is, he recognises, an ancient invitation, meant to beckon its recipient towards a long-lost world of hidden esoteric wisdom. When Langdon's revered mentor, Peter Solomon - philanthropist and prominent mason - is brutally kidnapped, Langdon realizes that his only hope of saving his friend's life is to accept this mysterious summons and follow wherever it leads him.
