Foxcatcher — William H. Hallahan

Former CIA agent Charlie Brewer finds himself the bait in a trap set by the United States and Iran. “Best thriller I've read in years” (The Washington Post).
 
Meet Robert McCall, a man sinking deep into the seamy underside of intelligence work, into activities he knows are both illegal and immoral. Now McCall sees a chance to redeem himself by thwarting a daring plot to smuggle America's most lethal high-tech war material to Iran. It's a chance he's ready to kill for.
 
The likely victim: Charlie Brewer, a brilliant, embittered former intelligence operative who is desperate for answers. He was framed for an illegal arms deal and doesn't know why; he's been released from prison and doesn't know why; he thinks he's been marked for murder and doesn't know why. When Brewer is approached by Iran's most ruthless secret agent, he realizes treason may be the price of survival.
