An exposé on the Communist party and its programs and goals within the United States.
From the book:
The masses of toilers, suffering under the burdens of the crisis, are keenly discontented and want to find a way out of their intolerable situation. They are alarmed at the depth, length and general severity of the crisis. They begin to realize that there is something rotten in Denmark, that there are fundamental flaws in the capitalist system. Their growing realization of this is further strengthened as they see the spectacular rise of Socialism in the Soviet Union. The masses are beginning rightly to sense that Communism has an important message for the human race, and they want to know what it is. Capitalism is deeply anxious that the masses do not get this message. Hence, from the outset it has carried on a campaign of falsification of the Russian revolution entirely without parallel in history. There has been a veritable ocean of lies in the capitalist press against the U.S.S.R.
