Summary

In Chapter Thirty, the narrator—a custody evaluator investigating the Barclay family—visits Mrs. Li, Rose's Chinese tutor, at her apartment in a modest Rockville building. The narrator climbs three flights of stairs because the building lacks an elevator, a detail that initially seems insignificant but becomes a clue. Mrs. Li's apartment is a study in contradictions: worn furniture and chipped laminate sit alongside expensive items like a Vitamix blender, a three-wick Nest candle, and a collection of delicate glass objects. The narrator immediately senses something off, comparing the apartment to a photo-negative of the Barclays' plastic-filled home—where glass has been removed—and notes the switched drinking glasses: she had once received a heavy, regal glass from Beth, and now Mrs. Li hands her a similar one, creating a sense of déjà vu.

The narrator questions Mrs. Li about Harriet and Rose, but Mrs. Li offers only evasive praise, describing Rose as a quick learner of Chinese characters and insisting she never discusses her parents. The narrator recognizes Mrs. Li as a well-coached witness, similar to hostile witnesses she's faced in court. As the narrator prepares to leave, she drops her pen, bends down to retrieve it, and spots an iPhone under her chair with the speaker function lit—someone is listening. She quickly deduces that Harriet is on the line, using Mrs. Li to monitor the conversation and gauge the narrator's stance on custody.

Instead of confronting the situation, the narrator decides to use the discovery to her advantage. She deliberately speaks to mislead Harriet, praising Beth as a good mother and Ian as a devoted father, while casually mentioning Ian's affair with the nanny and expressing her belief that Tina's death was a tragic accident. She even hints that she hopes Harriet remains involved in Rose's life. Mrs. Li, clearly uncomfortable, responds that Harriet would do anything for Rose—a statement that confirms the narrator's fears. The chapter ends with the narrator silently acknowledging that Harriet's devotion might be exactly what she's worried about.

Key Events

The narrator visits Mrs. Li's apartment and notices the stark contrast between shabby furnishings and expensive luxury items, including glass objects that seem out of place.
Mrs. Li offers lemonade and answers questions evasively, revealing nothing about Rose's parents or Harriet's involvement.
The narrator discovers an iPhone under her chair with the speaker on, realizing Harriet is listening to the entire conversation.
Instead of exposing the surveillance, the narrator uses it to plant false information, praising Beth and Ian and downplaying Tina's death as an accident.
Mrs. Li's final comment—that Harriet would do anything for Rose—underscores Harriet's potential dangerous loyalty.

Character Development

The Narrator: This chapter showcases her investigative instincts and strategic thinking. She quickly pieces together clues (the elevator's absence, the luxury items, the switched glasses) and transforms a potential threat (being overheard) into a tactical advantage. Her willingness to lie and misdirect reveals a pragmatic, even ruthless side, as she mirrors the Barclays' own deceptive tactics.
Mrs. Li: Initially appears as a loyal friend to Harriet, but her behavior—the coached answers, the relief when the narrator leaves, and her complicity in the surveillance—paints her as a willing accomplice. She's not merely a tutor but a gatekeeper, protecting Harriet's interests at all costs.
Harriet (off-page): Though not physically present, Harriet's presence looms large. Her decision to listen in on the conversation demonstrates her deep involvement in the custody case and her willingness to manipulate situations to control the narrative. The narrator's misdirection aims to exploit Harriet's protective instincts, suggesting Harriet may know more about Tina's death than she's revealed.

Themes, Symbols, or Motifs

Surveillance and Deception: The hidden iPhone is a literal symbol of surveillance, but the chapter also explores psychological deception—the narrator lies to Harriet, and Mrs. Li lies to the narrator. Everyone is watching and misdirecting.
Appearances vs. Reality: The apartment's juxtaposition of luxury and poverty mirrors the Barclays' own façade. The glass objects, which were removed from the estate, hint at hidden truths and the fragility of the family's carefully constructed image.
Glass Symbolism: Glass appears throughout—the vase, the curio cabinet, the wineglasses—and serves as a motif for transparency and fragility. The narrator's realization that the apartment is a
