What happens in Chapter 21 of Frankenstein?
Victor stands before Mr. Kirwin, the magistrate, as witnesses share their accounts against him. A fisherman recounts discovering a strangled young man on the beach; Daniel Nugent insists he saw a lone boat near the shore at that time; a woman confirms that she saw the same boat leave. When Victor is brought to see the body, he realizes it is Henry Clerval and collapses in convulsions, crying out that his "murderous machinations" have led to his closest friend's death. He succumbs to a fever for two months, during which he raves about being responsible for the deaths of William, Justine, and Clerval. He eventually wakes in a prison cell, looked after by a cold hired nurse who bluntly tells him he’d be better off dead. Mr. Kirwin, having read letters found on Victor that were addressed to Geneva, comes to visit and offers some solace. Victor, terrified that the creature has come to torment him, pleads for Kirwin to leave—until Kirwin reveals that it is his father, Alphonse. Alphonse reassures Victor that Elizabeth and Ernest are safe. After three months behind bars, the grand jury dismisses the case when it’s shown that Victor was on the Orkney Islands at the hour Clerval's body was found, leading to his release. While his father is ecstatic, Victor is still haunted by memories of Clerval's lifeless eyes and the creature's gaze. Determined to return to Geneva to protect his family and pursue the monster, Victor and his father board a ship to Havre-de-Grace. On deck at midnight, Victor takes a double dose of laudanum and slips into a nightmare where he feels the creature's grip on his neck, until his father awakens him.
Analysis
The chapter unfolds like a legal proceeding that ultimately spirals into personal horror. The initial courtroom scene is described in a detached, procedural tone—witnesses give statements, take oaths, and affirm facts—which makes Victor's sudden emotional breakdown upon seeing Clerval's body all the more shocking. The shift from third-person legal testimony to first-person anguish ("I feel yet parched with horror") marks the moment when a public event turns into a personal catastrophe.
Time feels compressed and fragmented throughout the chapter. Two months of fever are summed up in a single paragraph of delirium, and Victor's awakening in prison is likened to "awaking from a dream"—a phrase that recurs when he later refers to his entire past life as "a frightful dream," intertwining illness, guilt, and memory in ways that blur the line with reality.
The chapter maintains a stark contrast between cold indifference and genuine emotion. The hired nurse's brutal honesty, the physician's "utter carelessness," and the magistrate's initial harshness sharply contrast with Mr. Kirwin's quiet compassion and Alphonse's arrival, which Victor describes as "like that of my good angel." This juxtaposition underscores how fragile and rare human sympathy can be.
Imagery related to eyes recurs throughout: the magistrate's "keen eye," the monster's "watery, clouded eyes," and Clerval's "expressive eyes… languishing in death" continue to haunt Victor even after his release. The chapter concludes with a sea voyage, where laudanum, nightmares, and the sound of waves blend into a state that is neither sleep nor wakefulness, neither safe nor destroyed, capturing Victor's suspended existence between guilt and obligation.
