Part 6: Dolly, her children, and her mother, the Princess Shcherbatskaya, spend the summer with Kostya and Kitty. The couple's life is simple and unaffected, although Kostya is uneasy at the "invasion" of so many Shcherbatskys. He becomes extremely jealous when one of the visitors, Veslovsky, flirts openly with the pregnant Kitty. Kostya tries to overcome his jealousy, and briefly succeeds during a hunt with Veslovsky and Oblonsky, but eventually succumbs to his feelings and asks Veslovsky to leave. Veslovsky immediately goes to stay with Anna and Vronsky at their nearby estate. Anna Karenina is a novel by the Russian author Leo Tolstoy, first published in book form in 1878.
