The Duel: Duel'

"The Duel" is a novella by Anton Chekhov first published in 1891.
The story primarily focuses on Ivan Andreich Laevsky and Nadyezhda Fyodorovna, lovers who have moved to the Caucasus. Nadezhda is married to another man and some townspeople disapprove of the couple living together. Laevsky confides in his friend Samoylenko that he no longer loves Nadyezhda. Laevsky drinks, gambles, and lacks direction.
The scientist Von Koren feels that Laevsky's slovenly lifestyle is worthless. In fact, Von Koren feels killing Laevsky would be beneficial to society, an act of natural selection. Von Koren's dislike builds until he formally challenges Laevsky to a pistol duel.
The tension at the duel steadily increases. None of the men in attendance, with the possible exception of Von Koren, want to see the challenge completed. Fortunately for Laevsky, a deacon stops the duel before either man is slain. Laevsky's near-death experience leads him back to Nadyezhda.
