Jim Nicholson, a CIA vet, was the highest-ranking officer convicted of espionage. In 2004, his son, Nathan Nicholson, began to seek solace and advice from his father. The father raised his son's spirits but also coached him in spy-craft, in effect launching a second act of espionage from behind bars by using his son as a courier. In the ensuing year and a half, Nathan traveled the world selling secrets to the Russians, all the while getting deeper and deeper over his head.
