Katerina Izmailova's three murders and drowning
A childless merchant's wife in Mtsensk takes the clerk Sergei as her lover while her husband is away. She poisons her father-in-law Boris with rat poison in mushrooms after he flogs Sergei, then strangles her returning husband Zinovy with Sergei's help, then smothers the boy Fedya, a co-heir to the estate, and is caught when a crowd leaving vespers sees the killing. On the convict march to Siberia, Sergei discards her for the young prisoner Sonetka and mocks her publicly, and Katerina drags Sonetka into an icy river where both drown.
