Summary

In 1972, five years into his teaching career, Stephen Roper enjoys a reputation that frightens students before they even enter his classroom. His bachelor lifestyle invites occasional advances from new female teachers, but he remains uninterested—his voices always keep him company. For his summer road trip, he buys a deep blue Camaro and drives from Minnesota to New Mexico, then into Arizona. Near Bylas, Arizona, he picks up a young woman in a squaw dress who is heading to Globe. His intention is to kill her. Spotting a sign for Coolidge Dam Road, he deviates and strangles the woman after a violent struggle during which she bites his hand. He undresses her body to hide the bright dress, takes her turquoise necklace as a trophy, and dumps her corpse in the San Carlos Reservoir. He later treats his wound at a pharmacy, lies about a dog bite, washes his car, and checks into a motel, keeping the necklace as his only consolation.

Character Development

Stephen Roper – The chapter reveals his settled routine as a teacher and his complete emotional detachment. He is no longer questioned about his bachelorhood; his voices provide all the company he needs. His methodical planning—choosing a less flashy car, sticking to smaller roads, preferring strangulation to avoid blood evidence—shows an escalation in predatory sophistication. The violent struggle and the bite wound surprise him, exposing his anger toward victims who resist. His impulse to take the necklace confirms a growing need for trophies, linking physical control to psychological ownership.

The unnamed young woman – She remains an anonymous victim, described only by her dress and necklace. However, her fierce resistance (screaming, grabbing the door handle, biting) briefly disrupts Roper’s fantasy of an easy kill. Her ethnicity is implied by the "squaw dress" and later by Roper's internal racist epithet ("Damned Indians"), which underscores the intersection of misogyny and racism in his worldview.

The pharmacist – A minor character whose concerned questioning and advice highlight the banality of Roper’s cover story. The pharmacist’s trust emphasizes how easily a serial killer can pass as a normal citizen.

Themes, Symbols, and Motifs

Control and Trophy-Taking – Roper’s preferred method of strangulation involves close, hands-on domination. The necklace he takes becomes a portable reminder of his power over the victim. The ritual of removing the dress and placing it under the spare tire symbolizes his complete possession of the female body even after death.

Isolation and the Open Road – The chapter uses the geography of the American Southwest—deserts, remote highways, a secluded reservoir—to mirror Roper’s interior isolation. He feels "at home" in the vast, empty landscape because it matches the emptiness inside him. The freedom of the road enables his predation but also reinforces his loneliness.

Racism as Justification – Roper’s internal slur after the bite reveals how he uses racist thinking to dehumanize his victim and rationalize violence. The "Damned Indians" thought reduces the woman to a stereotype of the "savage" who fights back, allowing him to see his own cruelty as a righteous punishment.

The Danger of Appearances – The couples “snuggled together” in the Camaro fools passing drivers. The pharmacist sees only a friendly customer with a dog bite. Roper’s ability to maintain a respectable facade as a teacher and a traveler is a key motif, emphasizing that serial killers often blend into everyday life.

Why This Chapter Matters

This chapter is a turning point in the novel’s profile of Stephen Roper. It moves from establishing his backstory as a teacher to showing him in action as a serial killer on the move. The specific details of the crime—the blue Camaro, the trophy necklace, the use of a reservoir for disposal—will likely become crucial evidence later in the investigation. The chapter also deepens the reader’s understanding of Roper's psychology: his misogyny, his need for control, and his growing collection of symbolic objects. The bite wound introduces an element of vulnerability that may have future consequences (DNA, infection, or suspicion). Finally, the chapter sets up a pattern of summer road trips that could connect multiple unsolved murders across state lines.

Study Questions and Answers

1. Why does Stephen Roper choose to kill using his hands rather than a weapon?
He prefers strangulation because it leaves no traceable bullets or shell casings. He views it as a "clean kill" that is also "up close and personal," allowing him to feel direct power over his victim.

2. How does the setting of the American Southwest contribute to the chapter’s mood?
The dry heat, vast desert landscapes, and isolated roads reflect Roper’s inner emptiness and the anonymity he needs to commit murder. The mention of the Gila River and the San Carlos Reservoir provides a practical solution for disposal, yet the dry washes emphasize the harsh, unforgiving environment.

3. What is the significance of the victim's necklace?
The necklace serves as a trophy. Roper takes it after killing her, values it as something that "counts for something," and probably will add it to his cigar-box collection. It symbolizes his desire to hold onto a piece of each victim and his need to possess them even after death.
