15 Minutes is an interview podcast with the biggest names in the global security space. From 1985 to 1994, CIA officer Aldrich Ames was actually a spy for the Soviets. At the time of his arrest in ’94, he had compromised more CIA assets than any other mole in history. This week, The Cipher Brief’s Leone Lakhani spends 15 minutes with former CIA officer Sandy Grimes, who was instrumental in uncovering Ames. She had worked beside him as a young officer with the CIA’s Soviet bloc division. Here, she shares her personal experiences with Ames and why she believes he was such a valuable Soviet target.
