Robert Ludlum's The Bourne Legacy

Plot

Jason Bourne, international assassin of deadly repute, was an identity assumed by covert agent David Webb. Retired from the CIA and now a professor at Georgetown University, Webb's life is finally his own--until he becomes the target of an assassin and is framed for the murder of his two closest associates. Fighting for his life against unseen assailants, the Bourne identity asserts itself, leaving Jason Bourne in control. Barely a half-step ahead of his nemesis and the CIA, who believes he has gone rogue, Bourne finds himself a pawn in a larger, far deadlier game.
