I seem to remember reading that the Stasi was keeping a very close eye on Witt and harassing her for some time in order to coerce her into helping their propaganda efforts. I definitely remember they bugged her bedroom and then played (or sent her) tapes of some of her sexual liasons. Was she really a hard core spy, and if so, what real data could she have provided to them?
Stassi, at one time, along with Cubas DCI who was organized and trained ny Stassi, was the largest and most active intel group in the world. Dwarfing western groups in size and activity.
