Annie Lee Moss was a black woman who worked for the Army as a code clerk in the Pentagon. She was identified by an undercover agent of the FBI as a member of the Communist Party. Moss denied it, the Democrats sprang to her defense, and she has been treated ever since as an innocent victim of McCarthy.

As is well known, 'McCarthyism' was an alleged focus of political evil in the 1950s: Accusations of Communist taint, without factual basis; bogus lists of supposed Communists who never existed; failure in the end to produce even one provable Communist or Soviet agent, despite his myriad charges of subversion.

The historical novelist has to consider what has actually happened, while the SF writer is dealing in possibilities, but they are both in the business of imagining a world unlike our own and yet connected to it.
