Summary

{#summary}

Alexis wakes in her apartment and stares at the Breakfast at Tiffany's poster above her dresser. She recalls a dream in which she bought expensive pink leather gloves from a Madison Avenue shop and then wanted to return them because rats had gnawed holes in the fingers, like moths. The dream disturbs her because rats keep surfacing as traces in Austin's life, going back to the bite marks on his fingers the night they first met.

The night before, she had called Viet Nam National University in Ho Chi Minh City and left a message asking for either of two scientists who studied the long-term effects of herbicides on rats and the animal's evolution over the past half century. Checking her phone, she finds no calls and no emails from the university.

Despite having the day off, Alexis heads to the hospital for a 10:30 appointment with Sara Edens, a doctoral candidate in epidemiology who works with Dr. Ho-jin Myung. They meet in the cafeteria, where Sara explains that she works mostly with mice, using knockout and knock-in techniques to study arenaviruses and hantaviruses. The goal, she says, is to develop therapeutic agents, antibiotics, and vaccines.

Their conversation turns to the threat of rodent-borne disease in New York City. Sara notes that hantavirus has not yet appeared in the city but has spread to more than thirty states, including cases on Long Island. She describes the pathogens carried by rats in Manhattan basements—salmonella, E. coli, shigella—and explains that some are already resistant to common antibiotics. Rats themselves remain healthy carriers, and resistance can develop through natural selection or from consuming human food and waste.

Sara warns that a pandemic is coming and that New York City is the perfect place for one, given its dense population, millions of rodents, constant travel, and subway system. She mentions a 2015 study that found anthrax and bubonic plague in the subways. When Alexis asks who at the hospital works specifically with rats, Sara names Dr. Bhattacharya and Dr. Sinclair, and offers to ask around discreetly.

Sara's lab partner, Michael Fodder, briefly joins the table. He confirms that some of his work overlaps with Dr. Sinclair's research and describes Sinclair as a sane person for someone who spends most of his workday killing rats.

Later, at the gym, Alexis reflects on Austin—his green eyes, the Walt Whitman line she loves, and whether the glint she once read as wonder or exuberance was actually irresponsibility or deceit. She studies a photo of the wound on Austin's hand, magnifying it, and concludes that the weapon was not a screwdriver or an awl as she had previously thought, but a dart. Someone had slammed a dart into the back of his hand, breaking the bones.

She becomes certain that the trip, the disappearance, the torture, and the murder all connect to rats. Thinking back to her conversation with Sara about rapid mutation and hundreds of generations of rats in half a century, she links the Vietnamese rat—shaped by decades of napalm and herbicide exposure—to the threat of antibiotic-resistant disease. She calls private investigator Ken Sarafian and leaves a message asking him to call back, ready to share her theory.

Character Development

{#character-development}

Alexis Remnick: This chapter marks a shift from grief-stricken uncertainty to active theorizing. She moves from passively collecting clues to forming a concrete hypothesis that links Austin's death to rats and disease. Her reflection on Austin's eyes—wonder versus deceit—shows her wrestling with the gap between the man she loved and the secrets he kept.
Sara Edens: A new character who provides scientific credibility to Alexis's suspicions. She is practical, knowledgeable, and sympathetic, and her willingness to ask around discreetly gives Alexis a path forward.
Michael Fodder: A brief but useful appearance. His offhand comment about Dr. Sinclair's rat work reinforces the connection Alexis is building.

Themes, Symbols, or Motifs

{#themes-symbols-or-motifs}

Rats as a recurring symbol: Rats appear throughout the chapter—in Alexis's dream, in Austin's bite marks, in the research trail, and in the scientific discussion. They represent the hidden, creeping threat in Austin's life and the unseen forces that led to his death.
Pandemic preparedness and antibiotic resistance: Sara's warnings about the next pandemic and drug-resistant pathogens give the novel a contemporary public-health urgency and suggest that the danger Alexis faces is larger than one man's murder.
Vietnam War legacy: The Vietnamese rat, shaped by decades of napalm and herbicide use, ties Austin's death to the long aftermath of the war and to the idea that past violence leaves lasting mutations.
Deception and hidden identity: Alexis's meditation on Austin's eyes—wonder or deceit—underscores the theme of a man who was not what he seemed.
The dart as a clue: The revised weapon identification is a pivotal forensic detail that sharpens Alexis's theory and connects the murder to the bar where she and Austin met.
Evolution and mutation: Sara's explanation of rapid rat generations and mutation provides the scientific frame for Alexis's belief that the Vietnamese rat is central to the mystery.

Why This Chapter Matters

{#why-this-chapter-matters}

This chapter is the turning point where Alexis's scattered suspicions crystallize into a coherent theory. The conversation with Sara Edens supplies the scientific grounding for the rat connection, while the gym revelation about the dart gives her a concrete forensic clue. By the end of the chapter, Alexis has committed to a course of action—contacting Ken Sarafian—and the investigation shifts from passive grief to active pursuit. The chapter also deepens the novel's thematic concerns with pandemic risk, antibiotic resistance, and the lingering effects of the Vietnam War.

Study Questions and Answers

{#study-questions-and-answers}

How does the recurring rat motif function in this chapter, and what does it suggest about Austin's hidden life?

The rat appears in Alexis's dream, in the bite marks on Austin's fingers from the night they met, and in the research trail she follows. The motif suggests that rats are a thread running through Austin's life that Alexis only now notices—evidence of a hidden, dangerous world he kept from her. 2. What does the conversation with Sara Edens reveal about the novel's concerns with pandemic preparedness, and how does this connect to the Vietnam War legacy?

Sara describes New York City as a perfect setting for a pandemic, with dense population, millions of rodents, and a subway system that once tested positive for anthrax and plague. She also explains that rats mutate rapidly, producing hundreds of generations in half a century. This connects to the Vietnamese rat, shaped by napalm and herbicides, as a potential source of antibiotic-resistant disease—linking Austin's death to the long aftermath of the war. 3. Why does Alexis revise her theory about the weapon from a screwdriver or an awl to a dart, and what does this reveal about her investigative process?

While at the gym, Alexis magnifies the photo of the wound and notices the roundness of the puncture and the circular pattern of the bruise, which leads her to conclude a dart was used. This revision shows her moving from initial assumptions to careful examination of evidence, and it ties the murder weapon back to the bar where she and Austin met, reinforcing the sense that his death is connected to his past.
