When US police investigated a double murder in the 1980s, they had no idea they were about to uncover the most daring trail of forgery and deception America had ever seen. Mark Hofmann dared to forge on a level previously undreamt of as he manufactured historic documents at the core of the American constitution and history. And he fooled everyone - the FBI, the CIA, the Library of Congress, even the best forensic experts in the world and his own wife. Hofmann's story begins in Salt Lake City and a growing hatred of the Mormon church - a hatred which would lead him to his first criminal acts designed to dupe a society only too willing to believe tall tales. And it's a perfect training ground for his ultimate goal - to make a fortune and fool America itself. Ultimately however, his ambition turns to murder.
