Rodion Romanovich Raskolnikov, a former law student, lives in extreme poverty in a tiny, rented room in Saint Petersburg. Isolated and antisocial, he has abandoned all attempts to support himself, and is brooding obsessively on a scheme he has devised to murder and rob an elderly pawn-broker. On the pretext of pawning a watch, he visits her apartment, but remains unable to commit himself. Later in a tavern he makes the acquaintance of Semyon Zakharovich Marmeladov, a drunkard who recently squandered his family's little wealth. Marmeladov tells him about his teenage daughter, Sonya, who has chosen to become a prostitute in order to support the family. The next day Raskolnikov receives a letter from his mother in which she describes the problems of his sister Dunya, who has been working as a governess, with her ill-intentioned employer, Svidrigailov. To escape her vulnerable position, and with hopes of helping her brother, Dunya has chosen to marry a wealthy suitor, Luzhin, whom they are coming to meet in Petersburg. Details in the letter suggest that Luzhin is a conceited opportunist who is seeking to take advantage of Dunya's situation. Raskolnikov is enraged at his sister's sacrifice, feeling it is the same as what Sonya felt compelled to do. Painfully aware of his own poverty and impotence, his thoughts return to his idea. A further series of internal and external events seem to conspire to compel him toward the resolution to enact it.
