The Lady with the Dog is a novella by Anton Chekhov first published in 1899. Written while in Yalta, it is considered one of his most famous stories, (also called Lady with Lapdog).
The novella depicts what at first seems a casual liaison between a married man and a married woman in Yalta. Neither expects anything lasting from the encounter, but they find themselves drawn back to each other, risking the security of their family lives.
It tells the story of an adulterous affair between a Russian banker (Gurov) and a young lady (Anna) he meets while vacationing in Yalta. The story comprises four parts: part I describes the initial meeting in Yalta, part II the consummation of the affair and the remaining time in Yalta, part III Gurov's return to Moscow and his visit to Anna's town, and part IV Anna's visits to Moscow.
Vladimir Nabokov declared that it was one of the greatest short stories ever written.
