Robert Ludlum's the Bourne Shadow

This woman tells him an incredible story – that her sister disappeared with David’s help after the deaths of four terrorists in the mountains. Now men from this same extremist group are trying to hunt her down. Bourne remembers none of it, but when the Swiss bistro erupts in violence, he finds himself on the run, chasing the ghosts of his very first Treadstone mission. Operating on pure instinct, Bourne plunges into a maelstrom unlike any he’s ever experienced, hoping to rescue a woman he once loved. He soon discovers that no one in this world of shadows can be trusted – and everything he’s been told about his past is a lie.
