Jack observes that Denny enjoys the hotel-room life of girls, clubs, comic books, whiskey, and easy spending, though he also notices hints that Denny sometimes blacks out and becomes wild when drunk. The four go to an Italian restaurant and then a nightclub with strippers. Back at Denny’s room, they drink heavily, and a drunken Sue attempts a striptease before giving up. The night becomes a blur for Jack, who stumbles back to his room with one of the women and is intimate with her before passing out.

He wakes to find he has slept with Sue, not Mona. They are intimate again in the morning, and Sue tells him she has never experienced anything like the previous night before. She then worries about pregnancy before deciding she doesn’t care. As they talk, Denny bursts in, furious that Jack is with his girlfriend. Jack blocks Denny’s punch and lies, claiming they were both too drunk to do anything. Denny backs down and apologizes after Jack reminds him of his boxing background.

Over the next two weeks, Jack grows increasingly dissatisfied with his routine with Denny, Mona, and Sue. He becomes increasingly dissatisfied with Mona and increasingly attracted to Sue. When Denny runs out of money, he proposes robbing a liquor store, but Jack refuses, saying he came to San Francisco to think. Feeling betrayed, Denny later attacks Jack with a knife, but Jack instinctively disarms him and strikes him, breaking his jaw. Jack arranges for the hotel clerk to call a doctor while claiming Denny was mugged before sending Sue away. Left alone, Jack spends several days drinking and reflecting on his childhood in the orphanage, questioning the morality, purpose, and values he was taught. He briefly wonders whether life is worth continuing before dismissing the thought and continuing to drink. While he is passed out, Mona and Sue steal more than $100 from him. On the third day of his drinking binge, two police officers break into his hotel room and arrest him.

Jack is taken to the Hall of Justice on Kearny Street and placed in a city prison cell. When he is booked hours later, he is still half-drunk and beginning to feel sick, but the list of charges makes him understand that his arrest is real. The next morning in Municipal Court, he learns that he has been charged with statutory rape, resisting arrest, drunk and disorderly conduct, and theft. A warrant from Balboa County has also arrived, accusing him of kidnapping. Though Jack has never been to Balboa County, the judge orders him held for that charge.

Two detectives transport Jack to Balboa County in a chained and secured police vehicle. They are polite to him, even allowing him to smoke, and their casual manner makes the situation feel strangely ordinary. At the county jail, someone notices Jack’s fever, and he is taken to the county hospital. He spends nearly two weeks there with influenza, mostly silent and delirious. During the illness, he struggles to understand why he has been arrested and imagines the legal system moving forward without regard for his actual condition or innocence.

After Jack recovers, he meets District Attorney Forbes, who questions him about the kidnapping accusation. Forbes makes clear that he does not believe the charge. According to the accusation, Jack supposedly forced Mona and Sue into a car at gunpoint in Balboa County, took them to San Francisco, and kept them with him through threats. Forbes suggests that the girls likely blamed Jack to avoid punishment after being picked up by the police. However, Mona’s father has influence, and Forbes wants to manage the case politically. He offers Jack a deal: If Jack cooperates on the kidnapping charge, Forbes can help make the more serious San Francisco charges go away.

Jack is placed in the Balboa County felony tank while awaiting trial. The chapter describes the jail’s routines, class divisions among prisoners, meals, work system, and exercise periods. Mona visits Jack and admits that she and Sue signed statements against him because they feared reform school. She also reveals that her father is pressuring her to keep the story consistent. Later, Jack meets his assigned lawyer, Costigan, who explains how the legal arrangement will work: Jack will plead guilty at the municipal level, then later change course so the case can be reduced to a lesser charge. Jack agrees to cooperate because resisting would likely lead to worse punishment. The chapter ends with Jack furious at himself for cooperating and filled with rage at being treated like an animal.

Jack reflects on a previous stay in the jail in Idaho, where a tightly controlled “reformed” system denied inmates privileges and individuality, contrasting it with his current situation in the Balboa County jail. Here, the inmates run their own social order through a “sanitary court” led by an influential inmate named Mac McHenry. When Jack is summoned before this court, he resists violently, injuring several men before being subdued. McHenry orders Jack beaten and fined but later explains the court’s rules over breakfast, offering to waive part of Jack’s punishment in exchange for money and cooperation. Recognizing that cooperating is the only practical way to endure his imprisonment, Jack accepts, but grows to despise the inmate hierarchy, McHenry’s abuse of power, and his own complicity. Over the following weeks, he observes the lives of other inmates while becoming increasingly frustrated by the jail’s routines and power structure. His anger finally erupts when McHenry publicly humiliates a Spanish-speaking farmworker who does not understand the proceedings. Jack snaps and brutally attacks McHenry. As a consequence, Jack is locked in his cell for the remainder of his stay. The chapter concludes when Costigan informs Jack that the judge has rejected the planned reduction of the kidnapping charge to contributing to the delinquency of a minor, jeopardizing the plea agreement arranged with District Attorney Forbes.

Jack is tried, sentenced, and transferred from the Chino center to San Quentin prison. On the bus, he is heavily chained along with two other prisoners classified as “hard cases.” He views the journey as his last experience of freedom, terrified of returning to the madness he endured in “the hole.” During a rest stop, guards force the three hard cases to lie face down in a ditch under the hot sun. There, consumed by fear of returning to solitary confinement, Jack waits for a guard to make a mistake, reasoning that they will not kill him unless he kills them first—and that if he did, he would not have to go back to the hole. Back on the bus, he briefly feels sympathy for a tense guard, daydreaming about the pressures of the man’s job and home life. When the guard rebuffs his attempt to talk, Jack provokes him and another guard with insults. After a brief, tense exchange, Jack falls silent, realizing that he is unfairly casting the guards as villains simply because they hold power over the prisoners.

On the bus to San Quentin, Jack learns the story of another inmate, Claymore, a man who compulsively attempts to escape from every institution that holds him. Though not violent, Claymore vanishes from his factory assignment on his first day at San Quentin and is found after three days stuffed in a ventilating shaft. After returning to work, he escapes a second time and is caught over a month later in Colorado, ultimately being sent to Alcatraz.

Upon his own arrival, Jack is placed in isolation and meets with a prison counselor. The counselor’s humane approach, asking Jack what he wants to accomplish with his time, unnerves and frightens him, as he had prepared himself for harsh punishment. During a later meeting, Jack tests the counselor by refusing a factory job. When the counselor calmly asks what he would prefer, Jack requests kitchen work and the opportunity to finish his high school education. His requests are granted, leaving Jack disgusted with his own childish behavior. He is then moved into a cell with Billy Lancing, an old acquaintance who has successfully persuaded the prison authorities to change his racial classification. Billy, who also works in the kitchen, arranged for them to be cellmates.

Jack settles into his prison routine of kitchen work and classes, attempting to abandon hope by accepting prison as his permanent home. In the evenings, his cellmate, Billy, tells stories about his past, allowing both men to escape the mental confines of prison through memory. Jack gradually realizes that Billy is trying to understand how his past led him to prison. Billy recounts a time when he was broke in Idaho and won a small fortune hustling a stranger at pool. He then returned to the crap game and won another $900 before eventually deciding to enroll in college. He felt like an outsider and a phony there, and after concluding that love might give his life meaning, he impulsively married his college girlfriend. He soon found himself in a dull domestic life with two children, which he would periodically escape by returning to the road to gamble. The story is interrupted when news spreads that Claymore has escaped from San Quentin. Billy feels a deep, personal need for Claymore to remain free, a sentiment Jack cannot understand. When Claymore is recaptured and sent to Alcatraz, Billy broods for days.

Jack gradually adapts to life at San Quentin, learning the unwritten inmate code that demands a careful balance between defiance and compliance. His closest relationship is with cellmate Billy Lancing, who argues that the legal system punishes poor offenders more harshly than those who can afford better legal representation. Jack listens but resists Billy’s worldview, insisting he considers himself neither a victim nor a martyr.

Beneath their philosophical debate, sexual tension gradually develops between the two men. The chapter traces Jack’s mounting frustration with prison’s three options for sexual release—abstinence, masturbation, and homosexuality—as he discovers that same-sex relationships between men are far more widespread than he had imagined. He rebuffs a direct advance from a cook but privately acknowledges the contact aroused him. Rumors circulate among inmates that he and Billy are already involved, which Jack angrily confronts Billy about, deepening the awkwardness between them. The tension eases when Billy is caught masturbating and admits it openly, easing Jack’s anxiety about his own sexual frustrations.

The chapter closes with Jack’s extended reflection on sex as a mindless biological itch, which spirals into the realization that the same impulse caused his unknown parents to conceive and then abandon him, making his entire existence seem like an inconvenient byproduct of momentary gratification. Concluding that a physical relationship offers a practical solution to their sexual frustration in prison, Jack and Billy become lovers under a mutual agreement that their relationship will remain purely physical and without emotional attachment.

Billy Lancing, a talented pool player, manages maintenance at a bowling alley and lives a stable but unfulfilling life with his wife and children. He feels trapped by responsibility, is anxious about the racism his children will face, and begins a self-destructive affair with a woman named Luanne. His life is disrupted when a brash, high-rolling player from Arizona arrives and challenges him. The fat man first wins six straight eight-ball games while Billy never gets a chance to shoot. Billy then wins a single high-stakes game of one-pocket for $620, but the victory brings him no satisfaction, only a growing sense of emptiness and restlessness.

The fat man returns the next night, demanding a rematch. Seeking a definitive, all-or-nothing challenge, Billy agrees to play until one of them is broke. They initially play snooker before switching to nine-ball, continuing until four o’clock the following afternoon, playing for $5 a game before raising the stakes to $10. The fat man proves to be slightly better over the long haul and eventually wins all of Billy’s money, including his $1,000 caseroll. Completely broke, Billy gets an advance on his wages, packs his cue stick into its leather traveling case, and leaves the bowling alley, telling a young admirer that he is going to win the money back, although he knows this is untrue and that he is really leaving out of shame.

A few days before his death, Billy explains his personal philosophy to Jack, describing life in terms of “connection.” He uses pool as a metaphor for moments when everything aligns perfectly, and warns that when a connection is broken, a part of you dies. He then applies this to their own relationship, telling Jack that they are connected and that he loves him. Billy asks Jack to say he loves him back and to kiss him. Embarrassed and uncomfortable with the romantic turn, Jack refuses. Later, Jack learns that Clifford, the dominant wolf-pack leader, had announced he would sexually assault Jack within a week and was taking bets on it. Billy confronts Clifford in the prison yard after learning of the threat. In a swift, mutual attack that looks like they are just passing each other, Billy drives a sharpened spoon handle into Clifford’s abdomen while Clifford buries a seven-inch knife blade into Billy. Clifford dies within three hours. Hours later, Billy succumbs to his knife wound. A guard informs Jack, who is now held in segregation pending the investigation, of his friend’s death, leaving him devastated and weeping alone in his cell.
