After confronting Victor, the townspeople take him to Mr. Kirwin, the town magistrate. Victor hears witnesses testify against him, claiming that they found the body of a man along the beach the previous night and that, just before finding the body, they saw a boat in the water that resembled Victor’s. Mr. Kirwin decides to bring Victor to look at the body to see what effect it has on him: if Victor is the murderer, perhaps he will react with visible emotion. When Victor sees the body, he does indeed react with horror, for the victim is Henry Clerval, with the black marks of the monster’s hands around his neck. In shock, Victor falls into convulsions and suffers a long illness.
Victor remains ill for two months. Upon his recovery, he finds himself still in prison. Mr. Kirwin, now compassionate and much more sympathetic than before Victor’s illness, visits him in his cell. He tells him that he has a visitor, and for a moment Victor fears that the monster has come to cause him even more misery. The visitor turns out to be his father, who, upon hearing of his son’s illness and the death of his friend, rushed from Geneva to see him.
Victor is overjoyed to see his father, who stays with him until the court, having nothing but circumstantial evidence, finds him innocent of Henry’s murder. After his release, Victor departs with his father for Geneva.
On their way home, father and son stop in Paris, where Victor rests to recover his strength. Just before leaving again for Geneva, Victor receives a letter from Elizabeth. Worried by Victor’s recurrent illnesses, she asks him if he is in love with another, to which Victor replies that she is the source of his joy. The letter reminds him of the monster’s threat that he will be with Victor on his wedding night. He believes that the monster intends to attack him and resolves that he will fight back. Whichever one of them is destroyed, his misery will at last come to an end.
Eventually, Victor and his father arrive home and begin planning the wedding. Elizabeth is still worried about Victor, but he assures her that all will be well after the wedding. He has a terrible secret, he tells her, that he can only reveal to her after they are married. As the wedding day approaches, Victor grows more and more nervous about his impending confrontation with the monster. Finally, the wedding takes place, and Victor and Elizabeth depart for a family cottage to spend the night.
In the evening, Victor and Elizabeth walk around the grounds, but Victor can think of nothing but the monster’s imminent arrival. Inside, Victor worries that Elizabeth might be upset by the monster’s appearance and the battle between them. He tells her to retire for the night. He begins to search for the monster in the house, when suddenly he hears Elizabeth scream and realizes that it was never his death that the monster had been intending this night.
Consumed with grief over Elizabeth’s death, Victor returns home and tells his father the gruesome news. Shocked by the tragic end of what should have been a joyous day, his father dies a few days later. Victor finally breaks his secrecy and tries to convince a magistrate in Geneva that an unnatural monster is responsible for the death of Elizabeth, but the magistrate does not believe him. Victor resolves to devote the rest of his life to finding and destroying the monster.
Victor’s pattern of falling into extended illness in reaction to the monster suggests that the deterioration of his health is, to some extent, psychologically induced—as if guilt prevents him from facing fully the horribleness of the monster and his deeds. “The human frame could no longer support the agonizing suffering that I endured, and I was carried out of the room in strong convulsions,” he recounts of his despair at seeing Henry’s corpse, making an explicit link between psychological torment and physical infirmity. That Victor also falls ill soon after creating the monster and experiences a decline in health after the deaths of William and Justine points toward guilt as the trigger for this psychological mechanism.
Henry again serves as a link between Victor and society, as his death brings Alphonse to visit his son. “Nothing, at this moment, could have given me greater pleasure than the arrival of my father,” Victor says. As a result of spending so much time in Ingolstadt ignoring his family, and also as a result of the monster’s depredations, Victor becomes aware of the importance of interaction with family and friends.
Having failed to inspire love in Victor, the monster seeks to establish a relationship with his creator that would force his creator to feel his pain. By destroying those people dear to Victor, the monster, acutely aware of the meaningfulness of social interaction, brings Victor closer and closer to the state of solitude that he himself has experienced since being created.
