Three years ago, journalist Joey Watson learnt about the ultimate spy story. During the Cold War, the Australian spy agency ASIO was infiltrated by the enemy - one of their spies turned and began working for the KGB, the Soviet Union’s feared spy agency. They became a mole.  For decades, the mole's identity remained a mystery and the damage they caused unknown. To uncover the truth, Joey sets out to find them.   Joey starts by meeting the main suspect who was arrested in the early 1990s and uncovers a much bigger story about secrets and power. Nest of Traitors: Declassified is a behind-the-scenes peak at what goes into making the podcast series with Joey Watson and Clair Weaver.  If you have any feedback or information about this story you can email  [email protected] or you could send Joey a letter GPO Box 22, Sydney NSW 2000.
