This is a Dan Brown spoof. Remove Robert Langdon and insert Dan Lambert. Add a barrowload of laughs, incidents and nonsense.
Based on Wagner's 'Ring of Nibelung', this is a tale of treachery, terrorism and taunting. Midget terrorist Jensen Alberich for all his small stature had a massive chip on his shoulder. He teased the American authorities with cryptic clues on the days that he carried out his activities. His targets were famous historical landmarks. The CIA sent one of their top agents on an undercover mission into the suspected heart of the terrorist cell. The person that Alberich really wanted involved was Harvard Professor, Dan Lambert. Only Dan had the proven track record in code breaking. It became a game of cat and mouse as Dan raced against time to save some of the world's most iconic monuments from being blown to pieces.
