Robert Ludlum: The Bourne Ultimatum

The worl's two deadliest enemies in the ultimate showdown.
At a small-town carnival two men, each mysteriosly 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 what the Jackal wants: a final confrontation with Bourne. Now David Webb, professor of Oriental Studies, husband and father, must do what he hoped never to do again -assume the terrible identity of Jason Bourne. His plan is simple: to infiltrate the politically and economically omnipotent Medusa 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.
