In 1922 she moved to Warsaw and found a job as a salesgirl in a Communist bookstore; this employment, in the recent aftermath of the Polish-Soviet War, led to her being arrested for a week in Poznań (her official place of residence) before being released for lack of evidence. Kosicka and Gerould noted that "she took only a theoretical interest in Marxism and remained incapable of becoming directly involved in politics. Stanisława made not a single lasting friendship during her year in Warsaw, but as a result of her incarceration she grew obsessed with the victims of unjust imprisonment and judicial oppression, starting with Robespierre and going up to Sacco and Vanzetti in her own time."
