The world's two deadliest spies in the ultimate  showdown. At a small-town carnival two men, each  mysteriously summoned by telegram, witness a bizarre  killing. The telegrams are signed Jason Bourne.  Only they know Bourne's true identity and understand  the telegram is really a message from Bourne's  mortal enemy, Carlos, known also as the Jackal, the  world's deadliest and most elusive terrorist. And  furthermore, they know that the Jackal wants: a  final confrontation with Bourne. Now David Webb,  professor of Oriental studies, husband, and father,  must do what he hoped he would never have to do  again -- assume the terrible identity of Jason Bourne.  His plan is simple: to infiltrate the politically  and economically Medusan group and use himself as  bait to lure the cunning Jackal into a deadly trap  -- a trap from which only one of them will escape.
