In “Plautus: A Memoir,” Countess Alexandra is Leo Tolstoy’s adult daughter. The two were very close, so Alexandra is distraught when he dies, three years before the story begins. She takes to her bed and pretends to be ill, but she spends her time reading. When Plautus makes it to the Tolstoys’ house, the maid settles her in Alexandra’s room. The two become good friends and Alexandra reads books about feminist theory out loud to Plautus. Eventually, Alexandra gives up her solitude to get married and become a nurse in World War I. A decade later, Alexandra asks her husband to send Plautus to Virginia Woolf to get Plautus out of the war-torn Soviet Union—and as an excuse to smuggle her own prison diary out of the country. She eventually escapes to the United States.
