In the aftermath, Pyotr Stepanovich (who was mysteriously absent from the reading) seeks to persuade a traumatized Julia Mikhaylovna that it wasn’t as bad as she thinks and that it is essential for her to attend the ball. He also lets her know that the town is ringing with the news of another scandal: Lizaveta Nikolaevna has left her home and fiancé and gone off to Skvoreshniki with Stavrogin.
Despite the disaster of the reading, the ball goes ahead that evening, with Julia Mikhaylovna and Andrey Antonovich in attendance. Many of the respectable public have chosen not to attend but there is an increased number of dubious types, who make straight for the drinking area. Hardly anyone is dancing, most are standing around waiting for something to happen and casting curious glances at the Von Lembkes. A ‘literary quadrille’ has been especially choreographed for the occasion, but it is vulgar and stupid and merely bemuses the onlookers. Shocked by some of the antics in the quadrille and the degenerating atmosphere in the hall, Andrey Antonovich lapses back into his authoritarian persona and a frightened Julia Mikhaylovna is forced to apologise for him. Someone shouts «Fire!» and the news quickly spreads that a large fire is raging in part of the town. There is a stampede for the exits, but Andrey Antonovich screams that all must be searched, and when his distressed wife calls out his name he orders her arrest. Julia Mikhaylovna faints. She is carried to safety, but Andrey Antonovich insists on going to the fire. At the fire he is knocked unconscious by a falling beam, and although he later recovers consciousness, he does not recover his sanity, and his career as governor comes to an end. The fire rages all night, but by morning it has dwindled and rain is falling. News begins to spread of a strange and terrible murder: a certain Captain, his sister and their serving maid have been found stabbed to death in their partially burned down house on the edge of town.
Stavrogin and Liza have spent the night together and they wake to the dying glow of the fire. Liza is ready to leave him, convinced that her life is over. Pyotr Stepanovich arrives to impart the news of the Lebyadkins’ murder. He says the murderer was Fedka the Convict, denies any involvement himself, and assures Stavrogin that legally (and of course morally) he too is in the clear. When Liza demands the truth from Stavrogin, he replies that he was against the murder but knew it was going to happen and didn’t stop the murderers. Liza rushes off in a frenzy, determined to get to the place of the murders to see the bodies. Stavrogin tells Pyotr Stepanovich to stop her, but Pyotr Stepanovich demands an answer. Stavrogin replies that it might be possible to say yes to him if only he were not such a buffoon, and tells him to come back tomorrow. Appeased, Pyotr Stepanovich pursues Liza, but the attempt to stop her is abandoned when Mavriky Nikolaevich, who has been waiting for her outside all night, rushes to her aid. He and Liza proceed to the town together in the pouring rain. At the scene of the murders an unruly crowd has gathered. By this time it is known that it is Stavrogin’s wife who has been murdered, and Liza is recognized as ‘Stavrogin’s woman’. She and Mavriky Nikolaevich are attacked by drunk and belligerent individuals in the crowd. Liza is struck several times on the head and is killed.
Most of society’s anger for the night’s events is directed toward Julia Mikhaylovna. Pyotr Stepanovich is not suspected, and news spreads that Stavrogin has left on the train for Petersburg. The revolutionary crew, however, are alarmed. They are on the point of mutiny until Pyotr Stepanovich shows them Lebyadkin’s letter to Von Lembke. He points to their own undeniable involvement and tells them that Shatov is also determined to denounce them. They agree that Shatov will have to be killed and a plan is made to lure him to the isolated location where he has buried the society’s printing press. Pyotr Stepanovich explains that Kirillov has agreed to write a note taking responsibility for their crimes before he commits suicide. Shatov himself is preoccupied with the unexpected return of his ex-wife Marie, who has turned up on his doorstep, alone, ill and poverty-stricken. He is overjoyed to see her, and when it turns out that she is going into labour with Stavrogin’s child he frantically sets about helping her. The child is born and, reconciled with Marie, he is happy that he is going to be the father. That night the emissary from the revolutionary group—Erkel—arrives to escort Shatov to the isolated part of Skvoreshniki where the printing press is buried. Thinking this will be his final interaction with the society, Shatov agrees to come. As he shows Erkel the spot, the other members of the group jump out and grab him. Pyotr Verkhovensky puts a gun to Shatov’s forehead and fires, killing him. As they clumsily weight the body and dump it in the pond, one of the participants in the crime—Lyamshin—completely loses his head and starts shrieking like an animal. He is restrained and eventually quietened, and they go their separate ways. Early the following morning Pyotr Stepanovich proceeds to Kirillov’s place. Kirillov has been forewarned and is eagerly awaiting him. However, his aversion to Pyotr Stepanovich and the news of Shatov’s death arouse a reluctance to comply, and for some time they parley, both with guns in hand. Eventually Kirillov seems to be overcome by the power of his desire to kill himself and despite his misgivings he hurriedly writes and signs the suicide note taking responsibility for the crimes, and runs into the next room. But there is no shot, and Pyotr Stepanovich cautiously follows him into the darkened room. A strange and harrowing confrontation ends with Pyotr Stepanovich fleeing in a panic. A shot rings out and he returns to find that Kirillov has shot himself through the head.
Meanwhile, Stepan Trofimovich, oblivious to the unfolding horrors, has left town on foot, determined to take the high road to an uncertain future. Wandering along with no real purpose or destination, he is offered a lift by some peasants. They take him to their village where he meets Sofya Matveyevna, a travelling gospel seller, and he firmly attaches himself to her. They set off together but Stepan Trofimovich becomes ill and they are forced to take a room at a large cottage. He tells Sofya Matveyevna a somewhat embellished version of his life story and pleads with her not to leave him. To his horror, Varvara Petrovna suddenly turns up at the cottage. She has been looking for him since his disappearance, and her ferocity greatly frightens both Stepan Trofimovich and Sofya Matveyevna. When she realizes that he is extremely ill and that Sofya Matveyevna has been looking after him, her attitude softens and she sends for her doctor. A difficult reconciliation between the two friends, during which some painful events from the past are recalled, is effected. It becomes apparent that Stepan Trofimovich is dying and a priest is summoned. In his final conscious hours he recognizes the deceit of his life, forgives others, and makes an ecstatic speech expressing his re-kindled love of God.
When Shatov fails to return, Marie, still exhausted from the birth, seeks out Kirillov. Encountering the terrible scene of the suicide, she grabs her newborn baby and rushes outside into the cold, desperately seeking help. Eventually the authorities are called to the scene. They read Kirillov’s note and a short time later Shatov’s body is discovered at Skvoreshniki. Marie and the baby become ill, and die a few days later. The crime scene at Skvoreshniki reveals that Kirillov must have been acting with others and the story emerges that there is an organized group of revolutionary conspirators behind all the crimes and disorders. Paranoia grips the town, but all is revealed when Lyamshin, unable to bear it, makes a groveling confession to the authorities. He tells the story of the conspiracy in great detail, and the rest of the crew, with the exception of Pyotr Stepanovich who left for Petersburg after Kirillov’s suicide, are arrested.
Varvara Petrovna, returning to her town house after Stepan Trofimovich’s death, is greatly shaken by all the terrible news. Darya Pavlovna receives a disturbing letter from Nikolai Vsevolodovich, which she shows to Varvara Petrovna. News arrives from Skvoreshniki that Nikolai Vsevolodovich is there and has locked himself away without saying a word to
