Pyotr Petrovitch Luzhin
Quote 1
[Pyotr Petrovitch Luzhin:] "Resslich hated this girl, and grudged her every crust; she used to beat her mercilessly. One day the girl was found hanging in the garret. At the inquest the verdict was suicide." (4.2.41)
We don't blame you for shuddering. The girl in question is only 14. By Svidrigaïlov's own later admission, he sexually abused her, which caused her to kill herself.
