What are the motifs in Dorothy Parker: What Fresh Hell Is This? by Marion Meade?

Communism is a system of social organization in which all economic and social activity is controlled by a totalitarian state dominated by a single and self-perpetuating political party. The idea of Communism was introduced to Dorothy prior to the age of McCarthyism, and in her quest against all injustice, Dorothy was taken in by professional Communist propagandist, Otto Katz.
