Veteran CIA officer Max Waller has long been obsessed with the abduction and murder of his Agency mentor. Though years of digging yield the name of a suspect--an Iranian math genius turned terrorist--the trail seems too cold to justify further effort. Then Max turns up a photograph of the man standing alongside Osama bin Laden and a mysterious westerner whose face has been cut out, feeding Max's suspicion. When the first official to whom Max shows the photo winds up dead, the out-of-favor agent suddenly finds himself the target of dark forces within the intelligence community who are desperate to muzzle him.
