The triple agent

In December 2009, a group of the CIA's top terrorist hunters gathered at a secret base in Afghanistan to meet Humam Khalil al-Balawi, a Jordanian double agent who had gained access to the top commanders of al-Qaeda. Instead of providing information, Balawi detonated a bomb strapped to his chest, killing seven CIA operatives. Joby Warrick tells the story in his new book.
