The Bet and Other Stories by Anton Chekhov

This happened not so very long ago in the Moscow Circuit Court. The jurymen, left in court for the night, before going to bed, began a conversation about overwhelming sensations. It was occasioned by someone's recollection of a witness who became a stammerer and turned grey, owing, as he said, to one dreadful moment. The jurymen decided before going to bed that each one of them should dig into his memories and tell a story. Life is short; but still there is not a single man who can boast that he had not had some dreadful moments in his past.

One juryman related how he was nearly drowned. A second told how one night he poisoned his own child, in a place where there was neither doctor nor chemist, by giving the child white copperas in mistake for soda. The child did not die, but the father nearly went mad. A third, not an old man, but sickly, described his two attempts to commit suicide. Once he shot himself; the second time he threw himself in front of a train.
