cultivating as a diversion. The book charts Bourne's course from the United States, to France and then to Budapest in Hungary where he learns the final thing he needs to do—to stop Spalko's attack in Iceland. This, of course, all has to be done in the face of a CIA sanction for him to be immediately terminated, as he is believed responsible for the deaths of Conklin and Panov. There is also the matter of Spalko's hired assassin, Khan, who is able to track Bourne where everyone else cannot. Khan is revealed to be Joshua Webb, David Webb's son from his first marriage, who believes erroneously that he was left for dead by his father in Vietnam. Bourne, however, refuses to believe that Khan is Joshua, convinced that Joshua was killed decades ago, and continually tries to avoid him and the truth. Though Khan is at first working for Spalko, he eventually realizes that he has been used as a pawn in Spalko's personal game. After revealing later on to Bourne that Annaka Vadas, the daughter of Janos Vadas, is a traitor, he begins to feel that Bourne is not the hateful father that he had imagined. Unfortunately, Bourne is still unable to believe Khan is Joshua—until he hacks into the CIA database and discovers that Joshua's body had never been found. In a fit of rage, he attacks Khan, first believing that it is a conspiracy to hurt him, but is later captured by Spalko. After rescuing Bourne from Spalko, Khan makes an uneasy peace with his father. While on the plane to Iceland, however, Khan reveals a piece of information that finally convinces Bourne that Khan is his son. When Bourne subsequently reveals that he lost his memory while undercover as Cain, Khan begins to rethink his views regarding his father. After completing the operation and stopping Spalko, Khan makes up with his father and realizes that his hatred was always a reflection of his personal struggles and that, in truth, he truly loved Bourne. He requests Bourne, however, not to reveal his identity to Marie, in whose life he feels he has no place. Meanwhile, a mole in Spalko's company reveals to Deputy Director of Central Intelligence Martin Lindros that Spalko was behind everything, clearing Bourne's name.
