chunk: After failing to get al-Baluchi to give up information on an attack in Saudi Arabia, he and Maya eventually trick Ammar into divulging that an old acquaintance, who is using the alias Abu Ahmed al-Kuwaiti, is working as a personal courier for bin Laden. Other detainees corroborate this, with some claiming Abu Ahmed delivers messages between bin Laden and a man known as Abu Faraj al-Libbi.
  In 2005, Abu Faraj is apprehended by the CIA and local police in Pakistan. Maya is allowed to interrogate him, but he continues to deny knowing a courier with such a name. Maya interprets this as an attempt by Faraj to conceal the importance of Abu Ahmed.
