Summary
Tom Quinlan visits Amanda at the gallery to catch up and expresses concern over the break-in at her apartment, offering to come over if she feels unsafe. Amanda does not mention that Olivier has been performing that role. She is busy finalizing details for the gallery opening of an artist Pascal has been excited about. That evening, the opening is a success—all but two paintings sell—and the group celebrates with dinner at the Fontaine de Mars. Olivier stays the night. The next evening, Amanda attends a Hermès equestrian charity event alone. She is startled to learn that Olivier’s wife, Stephanie, is one of the judges. Amanda introduces herself, noting that Stephanie seems shy, plain, and socially awkward. They exchange a few words. Later, Amanda shares her impressions with Pascal, predicting that Olivier will never divorce such a vulnerable woman. When she finally tells Olivier about the meeting, they argue bitterly. Olivier insists he will leave Stephanie, but Amanda fears she will end up hurt. The chapter closes with Olivier at home, finding a note that Stephanie has left early for a two-month trip to England, forcing him to delay the conversation he had promised Amanda.

Character Development
Amanda grows more conflicted about the affair. Meeting Stephanie humanizes the wife, making Amanda feel like an “adulteress” rather than a woman in love. Her earlier confidence erodes, replaced by guilt and fear of being the one who gets hurt.
Olivier is caught between his desire for Amanda and his inability to act decisively. He promises divorce but offers no concrete steps, and his panic upon learning of Stephanie’s departure underscores his passivity.
Stephanie is sketched as a sad, plain, socially uncomfortable woman, completely unlike Olivier. The narrative implies she relies on her marriage for social protection, which makes leaving her seem cruel.
Pascal serves as a confidant, bluntly warning Amanda that the situation is precarious. His own pursuit of Delphine offers a lighter parallel.
Themes, Symbols, or Motifs
The Invisible Wife: Stephanie embodies the “other woman” trope reversed: the legitimate spouse is unknown to Amanda until now. Her appearance—severe, matronly, shy—challenges Amanda’s assumptions and forces her to confront the real emotional cost of the affair.
Guilt and Moral Debt: Amanda repeatedly worries about being the “bad guy” who destroys Stephanie’s fragile happiness. The chapter is saturated with guilt, not only from Amanda but also from Olivier’s reluctance to inflict pain.
Social Facades: The equestrian event highlights how separate Olivier’s and Stephanie’s lives are. Stephanie shines on horseback but is lost at a cocktail party. The chapter questions whether any marriage can survive such divergence.
The Stalker as Narrative Pressure: The breaher calls at 3 a.m. remind readers of the external threat to Amanda, contrasting with the internal emotional chaos she now faces.
Why This Chapter Matters
Chapter 10 is a turning point in Amanda and Olivier’s relationship. Until now, Amanda could romanticize being the mistress because Olivier’s wife was abstract. Meeting Stephanie forces her to see the human consequences, triggering a crisis of conscience. The chapter also exposes Olivier’s indecisiveness: despite his promises, he cannot bring himself to act. The postponement of the conversation with Stephanie sets up the central tension for the remainder of the novel. Additionally, the successful gallery opening marks Amanda’s professional peak, making the personal turmoil starker.
Study Questions and Answers
1. Why does Amanda’s opinion of Olivier change after meeting Stephanie?
Answer: Amanda had imagined Olivier’s wife as a cold, powerful woman. Instead, she finds a shy, awkward, sad woman who seems defenseless. This makes Amanda feel guilty and convinced that Olivier, a kind person, will never bring himself to divorce such a fragile spouse. She begins to doubt whether he has the courage to leave, and she fears she will be the one ultimately hurt.
2. How does the author use contrast between Stephanie and the redheaded riding partner to reinforce a theme?
Answer: The redheaded woman is described as vibrant, wearing a short sexy dress and high heels, while Stephanie is plain and severe in a Chanel suit. The stark contrast emphasizes that Stephanie lives in a world (equestrian competitions) where she feels competent, but outside that world she is socially awkward. This reinforces the theme of mismatched lives within a marriage: Olivier and Stephanie have no shared social life, and each seeks fulfillment elsewhere.
3. What does the stalker’s 3 a.m. phone call contribute to this chapter’s mood?
Answer: The interrupted sleep following the call mirrors Amanda’s restless emotional state after meeting Stephanie. The stalker adds an element of external danger, but Amanda is too preoccupied with her internal turmoil over the affair to fear the stalker as much as she might otherwise. The call also provides a narrative bridge, showing that despite the glamorous gallery opening, Amanda’s life is under siege from multiple sides.
