Robert Ludlum (Bourne 05) - The Bourne Betrayal

Jason Bourne takes a mission to rescue his only friend in the CIA, Martin
Lindros, who disappeared in Africa while tracking shipments of yellowcake
uranium. Once safely back in America, Lindros persuades Bourne to help
track the money trail of terrorists buying the nuclear material in Odessa.--

But once there, Bourne is hampered by confusing flashbacks of unfamiliar
places and events and he wonders: Is someone brainwashing him in order
to throw him off the trail? Worse, is the man he saved in Africa really
Martin Lindros? Now, Bourne is alone gathering evidence while trying
to stay one step ahead of the terrorists who won't let anyone stand
in their way of destroying the U.S.
