David McCloskey worked in CIA field stations across the Middle East throughout the Arab Spring and conducted a rotation in the Counterterrorism Center, briefing Congressional oversight committees, senior White House officials, ambassadors and military officials. He has since written several novels, including "Moscow X" and "Damascus Station", which has just been published in French. He joined us on Perspective to tell us more about his former life as a spy, what pushed him to write and the fine line between fiction and reality.
