In 1943, Beauvoir published She Came to Stay, a fictionalized chronicle of her and Sartre's relationship with Olga Kosakiewicz and Wanda Kosakiewicz. Olga was one of her students in the Rouen secondary school where Beauvoir taught during the early 30s. She grew fond of Olga. Sartre tried to pursue Olga but she denied him; he began a relationship with her sister Wanda instead. Sartre supported Olga for years until she met and married her husband, Beauvoir's lover Jacques-Laurent Bost. At Sartre's death, he was still supporting Wanda. In the novel, set just before the outbreak of World War II, Beauvoir makes one character from the complex relationships of Olga and Wanda. The fictionalized versions of Beauvoir and Sartre have a ménage à trois with the young woman. The novel also delves into Beauvoir and Sartre's complex relationship and how it was affected by the ménage à trois.
