Robert Ludlum (Bourne 04) - The Bourne Legacy

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.
