⚠️ 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
Chapter 39, dated 28 February 2014, is a letter from the wife to Adam on their sixth wedding anniversary. She opens by declaring it a good year for them both, noting that Henry Winter commissioned Adam to adapt another novel — a murder mystery with horror elements called The Black House — and that Adam's own screenplay Rock Paper Scissors has entered pre-production, with October O'Brien attached as an A-list actress.
The wife credits October for much of their recent good fortune, though she also mentions that October has been having a difficult time: the press discovered her speeding offences, and she now faces court and possible loss of her licence. When the wife mentioned that she and Adam had never been away for an anniversary because of his work, October offered them her renovated former winery in Champagne, France, for the occasion.
The couple travel via the Eurotunnel with their dog Bob, who uses his pet passport for the first time. They drive through Paris, where the wife wants to see Notre-Dame, and after lunch at a café on the Seine they stroll through the Bouquinistes — the famous riverside book stalls. Adam, in his element, shares facts about the stalls (including their UNESCO World Heritage status) and his habit of smelling books, which the wife now finds endearing rather than peculiar. She reflects on marriage and storytelling, observing that couples don't necessarily run out of stories but retell them differently each time, and that nobody can ever fully know another person. They share a public kiss — something they haven't done in years — and the wife feels they briefly become the people they used to be.
October's villa is located near Moët & Chandon on the Avenue de Champagne, surrounded by vineyards. The house was once a derelict winery but has been transformed into a luxury home with wooden beams and glass windows. October, under thirty, owns four homes and has apparently caught the renovation bug, eyeing another abandoned property. The couple arrive late, eat Camembert, jam, and bread with champagne, and go to bed.
The next morning, Adam gives the wife an iron bookmark engraved with a pun about being glad he married her — iron representing their sixth year. She admits she looked disappointed at first, having expected something different. She gives him a vintage iron key, and when he asks what it opens, she says it opens a secret. They then have sex twice in October's bedroom, surrounded by photographs of the actress winning awards and posing with celebrities. The wife admits she had to look away, worried October was watching, and confesses she hopes Adam was picturing her rather than their host.
While Adam showers, the wife snoops. She finds inspirational mottos around the house, including one about getting what you work for and another about being the person your dog thinks you are. She also discovers unopened mail addressed to R. O'Brien. When she asks if October is married, Adam explains that October is a stage name meant to protect her privacy. He quickly changes the subject.
The letter closes with the wife revealing that she gave the iron key because she wants to tell Adam the truth about everything — but when he unwrapped it, something felt wrong. She decides not to jeopardise their present happiness with her past, choosing to let them live this happy version of themselves a little longer. She signs off as your wife.

Character Development
The wife (narrator): This chapter shows her caught between contentment and concealment. She is genuinely happy — she describes Adam's happiness as contagious and savours their time together — yet she is also aware of the gap between the life she presents and the truth she carries. Her decision to give the iron key and then pull back from explaining it captures her internal conflict: she wants honesty but fears its cost. Her jealousy toward October, her discomfort in the actress's bedroom, and her snooping all reveal an insecurity that sits beneath her cheerful narration.
Adam: Though we only see him through his wife's eyes, Adam emerges as affectionate and playful — the pun on the bookmark, the public kiss, his enthusiasm for books. His quick change of subject when the wife asks about R. O'Brien is notable, hinting that he may be keeping things from her as well.
October O'Brien: Present only through the wife's observations, October is portrayed as glamorous, successful, and generous — but also opaque. The R. O'Brien detail and the stage name suggest a hidden identity, and her absence from the villa while the couple stay there adds an unsettling quality.
Themes, Symbols, or Motifs
Iron: The chapter's title and central symbol. Iron represents the sixth anniversary, but the two iron gifts carry different meanings: the bookmark is a light-hearted pun, while the key is loaded with significance — a key that opens a secret, offered but not explained. Iron also suggests strength and permanence, qualities the marriage may or may not possess.
Secrets and the cost of honesty: The wife's final reflection is the chapter's emotional core. She wants to tell the truth but decides the timing is wrong, prioritising present happiness over future clarity. The R. O'Brien discovery adds another layer: secrets exist on both sides.
The retelling of shared stories: The wife's meditation on how couples retell stories differently each time speaks to the novel's larger interest in unreliable narration and the versions of ourselves we present to others.
Renovation and transformation: October's villa — a derelict winery turned luxury home — mirrors the idea of transformation, and perhaps the wife's own desire to renovate her life or marriage.
Feeling watched: In October's bedroom, surrounded by her photographs, the wife feels observed. This motif of surveillance recurs throughout the novel and adds tension to what should be a romantic scene.
Why This Chapter Matters
Chapter 39 is a turning point in the novel's emotional architecture. It is the first time the wife explicitly articulates her desire to confess her secret, and her decision to delay that confession sets up the tension that drives the remaining chapters. The chapter also deepens the mystery around October O'Brien — the R. O'Brien detail and the stage name raise questions about who she really is and what her relationship with Adam involves. Finally, the chapter's setting — a borrowed house full of another woman's photographs and possessions — creates an atmosphere of unease that contrasts sharply with the wife's insistence that this is one of their best anniversaries ever. The gap between what she says and what she feels is the chapter's quiet engine.
Study Questions and Answers
1. Why does the wife give Adam an iron key but then decide not to explain what it opens?
The key is her attempt to symbolically offer him the truth about her past. She says she wants to tell him everything, but when she sees him holding the key, she hesitates, deciding that revealing her secret might ruin their present happiness or jeopardise their future. The key becomes a promise deferred rather than a confession delivered.
2. What does the discovery of the R. O'Brien mail reveal about October and Adam?
It reveals that October O'Brien is a stage name — her real identity begins with R. — and that Adam knows this and is comfortable keeping it from his wife. Adam's quick change of subject suggests he may be protecting October's privacy, but it also hints that he is keeping information from the wife, mirroring her own secrecy.
3. How does the chapter use the setting of October's villa to create unease?
The villa is beautiful and generous — a gift from a glamorous friend — but it is also full of October's presence: her photographs on the walls, her mottos, her mail. The wife feels watched in the bedroom and admits she hopes Adam was picturing her during sex. The setting thus becomes a reminder of the third person in the marriage, even as the couple tries to celebrate their anniversary alone.
