Leo Nikolaevich Tolstoy's wife, Sofya Andreevna (1844–1919), even during her husband's lifetime, became no less a legendary person than he himself. Newspapers wrote about her, she was filmed by the pioneer of Russian cinema Alexander Drankov, her image was captured in the first feature films about the life of the “great Leo”. And today her figure attracts biographers, filmmakers and theater workers. She lived with Tolstoy for almost half a century, gave birth to thirteen children, and was his faithful friend and literary assistant. But it was precisely because of the conflict with his wife that Tolstoy fled from Yasnaya Polyana in 1910. Writer and journalist, winner of the Big Book Prize Pavel Basinsky decided to write a book about Sofia Tolstoy in an unusual format - online dialogues with the poet and prose writer from St. Petersburg Ekaterina Barbanyaga. Two views - men and women. Two points of view on the fate of the great wife of the great writer. The Appendix publishes little-known texts by S. A. Tolstoy and essays about her by Vlas Doroshevich and Maxim Gorky.
