Summary (Chronological)
At 6:30 a.m., Martha enters the bedroom with two coffees and catches Al in his underwear, flushed and hurriedly pushing a worn leather bag into the wardrobe. The bag, secured with a brass padlock, belonged to his late father—a rural GP who was beloved by his patients but who Al describes as a narcissistic sociopath who destroyed his life. Al keeps it to remind himself that his father had a good side too. Martha asks what he’s doing, and Al dismisses it as just looking for something, though his strange energy lingers. She doesn’t push, wanting to preserve the recent warm mood between them.
They chat about the day ahead: Martha will take Nala to the childminder later than usual because Al has been helping at her florist shop, opening up and running deliveries. She reflects on how reliable and adult his help feels compared to the fleeting Gen‑Z staff she usually employs. Al showers, and Martha, still unsettled by the image of him hiding the bag, kneels at the wardrobe. The padlock is undone. Inside the main body she finds nothing, but one of the smaller compartments holds a slight bulge. Her fingers trace the shape of a phone. Her stomach plummets—a secret phone. She starts to open the zip, but the water stops. She quickly returns the bag to its spot, her heart hammering, coffee trembling in her hand.
Key Events
- Martha walks in on Al stashing the locked leather bag and notices his flushed, evasive demeanour.
- She recalls the bag’s backstory: it belonged to his abusive father, a well-liked GP; Al keeps it as a balance against his hatred.
- The couple discuss logistics—Martha will drop Nala at the childminder later because Al now opens the shop; she internally celebrates having a grown-up colleague.
- While Al showers, Martha opens the bag, finds the main compartment empty but discovers a hidden phone in a smaller, unlocked pouch.
- Just as she is about to investigate further, the shower stops and she panics, shoving the bag back and trying to compose herself.
Character Development
- Martha: Her gratitude for Al’s steady presence and the morning intimacy—liking his sleepy smell, appreciating his help—is undercut by a visceral moment of doubt. The sight of the bag and especially the phone makes her stomach drop, showing that beneath her contented surface she retains a sharp instinct for threat. She chooses to snoop rather than confront, revealing both her anxiety and her willingness to uncover uncomfortable truths.
- Alistair (Al): His flushed face and the hurried action of hiding the bag suggest concealment. Yet he quickly recovers his pleasant, helpful exterior, agreeing to open the shop. The chapter plants the first concrete seed that Al may not be exactly who he seems, turning a previously romantic partner into a potential source of danger.
Themes, Symbols, or Motifs
- The locked leather bag: A physical symbol of Al’s traumatic inheritance. Once a container for his father’s things, it now holds a secret—possibly signalling that Al himself is replicating hidden, harmful patterns.
- The hidden phone: A classic thriller motif representing a double life, secrets from a partner, or illicit communication. In a domestic setting, it immediately corrodes trust.
- Domestic illusion vs. suspicion: The chapter contrasts a cosy morning (coffee, warm bed, humming in the shower) with a creeping sense of wrongness. The snowy memory of a “special family” is threatened by one small discovery.
- Professional reliance: Martha’s reflection on Al as a “game changer” at the shop makes his potential betrayal feel more devastating; she has handed him access to her business and daily routine.
Why This Chapter Matters
Chapter Eighteen marks a turning point in the narrative of trust. Until now, the reader has seen Al largely through Martha’s hopeful eyes. Here, Jewell introduces tangible evidence that something is being concealed—a secret phone hidden in a bag tied to a traumatic past. The chapter functions as a suspenseful hinge: the domestic harmony that Martha cherishes is suddenly fragile, and the reader begins to share her doubt. It raises the stakes by showing just how intertwined Al has become in her life (home, shop, childcare logistics), making the coming revelation—whatever it is—certain to upend everything.
Study Questions & Answers
-
What does Martha discover in Al’s bag, and why is it significant? She finds a phone hidden in a small, unlocked compartment. Its significance lies in its secrecy: the bag itself is associated with Al’s father and trauma, and a concealed phone immediately suggests hidden communications or a double life, shattering the image of openness Al has cultivated.
-
How does Martha’s perception of Al shift during this chapter? Initially she feels deep gratitude and affection, savouring the domestic routine and his help at the shop. After catching him hiding the bag and especially after touching the phone, her stomach drops and her heart races. She moves from trust to sharp suspicion, though she masks it to avoid spoiling the mood.
-
What role does the bag’s family history play in amplifying the tension? Al told Martha the bag belonged to his father, a well-respected GP who was abusive at home. By keeping the bag, Al attempts to hold onto the good public persona. Finding a secret object inside this contested heirloom suggests he may be repeating the cycle of a charming exterior masking harmful secrets, linking past betrayal with present unease.
