You should tell us who the Commies were ~ it's probably not too late eh.
You met SAD in Indonesia? If so, perhaps you recorded your impressions here on FR previously?
Based on my personal experience interviewing with the CIA and reading their 15 book reading list that they suggested to help recruits understand what the agency, espionage and counterespionage was all about, I would say that if Stanley Ann was a KGB operative recruited in her youth (by KGB asset FM Davis, for example) you have described a truly orgasmic setting for a KGB agent to exploit in scouting, grooming and recruiting future KGB assets!
If Stanley Ann was hired by the US Embassy to do low level clerical stuff not requiring a clearance, then as a conveniently located ex-pat she might never have gone through a US security clearance. Given that she and her father were likely "associates" of FM Davis, clearance might have been denied.
