Chapter 23 Summary and Analysis

⚠️ Spoiler Warning: This guide contains detailed spoilers for the entire novel. Proceed only if you've finished reading or are comfortable knowing the plot.

Summary

The chapter opens with Alexis being roused from sleep at 9:20 a.m. by an intercom buzz from her apartment lobby. A FedEx courier needs her signature on a package. Still groggy, she pulls on sweatpants and goes downstairs in her sleeping T-shirt and slippers, not expecting anything and unable to imagine what the package could be.

The delivery turns out to be a Tyvek pack containing a diplomatic pouch sent from Toril Bjornstad, the FBI attaché in Cambodia. The handwritten note explains that a tourist found Austin's bike bag near the top of the Hai Van Pass, where he had been riding on Highway One the day he died. The bag contained nothing that shed new light on the accident, but Captain Nguyen forwarded one item — a dress — which Bjornstad assumed Austin had bought for Alexis. She sent it along as an act of kindness.

Alexis examines the dress. It's beautiful — a silk garment with a kaleidoscopic pattern of red, purple, and orange waves, similar in cut to the white cocktail dress Austin had bought her that summer. She speculates that Austin must have detoured into Hoi An the morning he died, perhaps planning to surprise her with it in December.

But when she holds the dress against herself in front of the mirror, her stomach lurches. The dress is nowhere near her size. She's five foot six, and this dress is for a woman at least five or six inches shorter, with far smaller breasts and almost no hips — a petite woman, a size zero. She checks inside for a tailor's tag but finds none. Either the tailors accidentally used the wrong measurements, or Austin had the dress made for another woman. Given what she's learned about him since his death, she's convinced it's the latter.

Before heading to work, Alexis calls Ken Sarafian to tell him about the dress. He tries to reassure her that it could have been an innocent mistake at the tailor's, but she senses from his tone that he harbors similar suspicions. She also emails the lead researcher at the university in Ho Chi Minh City who conducted the rat study — her second attempt — because she still hasn't heard back. If there's no response by the end of her shift, she plans to try calling.

Alexis's mind is a mess. Part of her is so indignant at the possibility that Austin bought a dress for another woman that she wants to let him go entirely — to release his memory and move on. But then she remembers the man she knew since March, who treated her with tenderness and love, and who she's convinced was tortured before he was killed. Her dogged nature won't let her abandon the search for truth.

She works a day shift at the ER. Her first patient is a sixty-five-year-old woman with lung cancer who believes she's in remission but is coughing up blood. Alexis knows the CT scan will be bleak and the woman will need to be admitted. The patient's husband insists it's probably just pneumonia, and Alexis plays along with the charade while her heart breaks a little.

Her second patient is a heavyset Chinese takeout delivery man who was hit by a cab. He's avoided broken bones but has a gash on his forearm needing stitches and likely a concussion. Looking at his cracked helmet reminds Alexis of Austin's, and she suddenly hates bicycles — unreasonably, she knows, but she doesn't care.

Her third patient is a young single mother who fell down the last dozen subway stairs while wrangling her toddler and stroller. She protected her son but broke an arm and a leg and will be hospitalized overnight, possibly longer. She works at a noodle bar, has no insurance, and her support system consists mostly of her own mother. Alexis worries the fall could trigger a cascade of events ending in homelessness.

On her break, Alexis walks outside into the crisp autumn air, past pharmaceutical company offices and hospital buildings, to the East River. She watches a plane descend toward LaGuardia and looks back at the wing where Sally Gleason and Oscar Bolton work — where Austin used to go in the mornings. She doesn't know Oscar and can't figure out Sally, who seems nurturing one minute and darkly jokey the next.

She reflects on how quickly lives change. She's seen it twice today already — the cancer patient and the mother who fell. And she recalls her own father's death: one morning he went to work and never came home, his car sliding into a concrete bridge stanchion at high speed. That morning at breakfast, none of them knew it would be the last time they were all together. Before and after, she thinks — that's the way of the world.

She remembers a self-defense course she took in college, which comes back to her now when she thinks about how quickly a person's world can change. She wonders when — if ever — the Harpers will watch videos of their son as a boy. She hasn't looked at videos of her own father in years; it's too painful.

Before heading back inside, she pauses at a sanitation department sign taped to a lamppost. It features a drawing of a rat and a rose with a terrible limerick about rats eating litter and dog poop. She takes in the awfulness of the poem and the image. Then, as she looks up at the building, something clicks. She knows Columbia is studying New York City rats and their pathogens and antibiotic resistance. She thinks of the article abstract she found in Austin's apartment and realizes that somewhere in the labs in the wing where her boyfriend used to work, her university hospital might be researching rats too.

Character Development

Alexis is caught between two competing impulses this chapter. Her indignation at the possibility of Austin's infidelity makes her want to let go of his memory entirely — to release his wrists at the edge of a cliff, as she puts it. But her love for the man she knew, and her conviction that he was tortured before being killed, pull her back. Her doggedness — her refusal to let go without knowing the truth — emerges as a defining trait. Her work in the ER also reveals her empathy and professional competence: she plays along with the lung cancer patient's husband's denial, worries about the single mother's precarious situation, and finds her own grief refracted through her patients' suffering.

Ken Sarafian appears briefly but meaningfully. His attempt to reassure Alexis about the dress rings hollow — she senses he shares her suspicions, which deepens her unease.

Themes, Symbols, or Motifs

Grief and mourning: The dress functions as a memento of the dead — a physical object that both comforts and torments Alexis. It's a tangible piece of Austin's last day, but it also raises painful questions about who he really was.

Suspected infidelity: The dress's wrong size is the chapter's central mystery. It forces Alexis to confront the possibility that the man she loved had secrets — a theme that echoes Ellie Thomas's earlier conjectures about mistresses.

Fragility of life: Alexis's ER patients — the cancer patient, the bike delivery man, the mother who fell — all illustrate how quickly a life can be upended. Her father's death is the foundational example: one ordinary morning, and everything changed.

Truth-seeking: Alexis's determination to contact the rat researcher, her call to Sarafian, and her refusal to let the dress question go all demonstrate her commitment to finding out what really happened to Austin.

Rat research: The sanitation sign and Alexis's realization about the hospital's possible rat research connect Austin's work to a larger mystery, suggesting his death may not have been an accident.

Letting go vs. holding on: Alexis's internal conflict — whether to release Austin's memory or pursue the truth — is the chapter's emotional core.

Why This Chapter Matters

This chapter deepens the central mystery of Austin's death on two fronts. First, the dress revelation introduces the concrete possibility of infidelity, complicating Alexis's grief and her memory of the man she loved. Second, the rat research connection — Alexis's realization that her own hospital may be conducting the same kind of study Austin was involved with in Vietnam — suggests a potential link between his work and his death. The chapter also grounds Alexis's emotional state in her professional life, showing how her daily exposure to human fragility shapes her perspective on her own loss. Her refusal to let go, despite her anger, sets up the investigation to come.

Study Questions

1. Why does the dress's size matter so much to Alexis?

The dress's size matters because it's evidence. If Austin had the dress made for Alexis, it would have been tailored to her measurements — the same measurements used for the cheongsam he bought her in Hoi An. The fact that it's clearly for a much smaller woman means either the tailors made an error or Austin ordered it for someone else. Given what Alexis has learned about Austin since his death, she's convinced it's the latter, and this suspicion threatens to rewrite her entire understanding of their relationship.

2. How does Alexis's work in the ER shape her perspective on her own grief?

Alexis's ER patients provide a constant reminder of how quickly lives can change. The lung cancer patient who believes she's in remission but is coughing up blood, the bike delivery man with a concussion, and the single mother who broke her arm and leg in a subway fall all illustrate the randomness of tragedy. Her father's death — an ordinary morning that ended in a fatal car crash — is the foundational example. This perspective both validates her grief and gives her a framework for understanding it: before and after is simply the way of the world.

3. What does the rat sign and Alexis's realization about hospital research suggest about the direction of the investigation?

The sanitation sign about rats triggers a connection in Alexis's mind: she recalls the article abstract she found in Austin's apartment about rat research, and she realizes that the hospital wing where Austin worked — the same wing where Sally Gleason and Oscar Bolton work — might be conducting similar research. This suggests that Austin's work, and possibly the rat study in Vietnam, may be connected to his death. The chapter hints that the mystery is not just personal (infidelity) but professional (research-related), pointing toward a larger conspiracy that Alexis will need to unravel.
