Robert Ludlum’s:The Bourne Shadow

It's been over a decade since Nash Rollins recruited a brilliant, talented, but disaffected young man named David Webb to join Treadstone. Webb became the agent known as Cain and later took on the identity of Jason Bourne. That violent winter, which included Cain's first mission for Treadstone, was also a story of betrayal in ways that David never knew. So, after the injury that erased Bourne's whole life, Nash lied about the circumstances of David's recruitment to Treadstone. He was afraid that learning the truth might drive Bourne out of the agency forever. But now, when Bourne meets a woman who recognises him as David Webb, the secrets of those days begin to come out and Bourne is forced to confront the dangerous ghosts of a past he doesn't even remember.
