Controversy. Conspiracy. Confusion. History is fraught with events -- from local to global -- that have never been satisfactorily explained. What caused the dinosaurs to perish? How were the Egyptian Pyramids built? What happened to the great Inca civilization? Was John Wilkes Booth part of a large, sinister plot?
