The great spy stories of 60 Minutes

We knew that spy stories have been a great tradition at 60 Minutes, but we never imaged what we found in the archives this week.

When Overtime learned that Steve Kroft was reporting on a possible case of Chinese espionage for Sunday's broadcast, we decided to take a spin through the old tapes, and we discovered dozens of stories on spooks, traitors, and double agents of every stripe.

Our archive is a veritable gold mine for spy fans, and with those fans in mind, we present this highlight reel of great moments in spy reporting from 60 Minutes.
