Summary

The chapter opens in the present day with Mathéo conducting a routine inspection of the winery's equipment—checking pressure gauges, heaters, coolers, and drainage seals. The business is thriving, on track for record production despite climate pressures that have damaged much of the French wine industry. Mathéo takes particular care because he was the one who persuaded his father, Christophe, to expand from a modest operation into one of the largest wineries in Languedoc-Roussillon, a two-million-euro investment expected to pay for itself within three years.

Skipping breakfast, Mathéo heads to the cafe, greets staff, and settles with a pastry and hot chocolate. His mind drifts to the improbable chain of events that shaped his life. If Maurice hadn't called in sick, Christophe wouldn't have driven the van to Montpellier. If the van had been fully charged, he wouldn't have stopped at a charging station. If he hadn't lit a cigarette and walked around, if he'd looked left instead of right—he wouldn't have spotted a child's foot under a tarpaulin and found Mathéo's semi-conscious body beneath it.

Mathéo's memories of that day are fragmentary. He recalls being carried to a van, too weak to resist, but sensing kindness in the stranger's eyes. He was given water. Christophe spoke French, then switched to English when he realized the boy understood little. Mathéo couldn't answer basic questions—his name, age, or how he came to be in France. Christophe suspected human trafficking from the UK, knowing gang leaders were ruthless with children.

Mathéo woke in a farmhouse bedroom, tucked under a quilt, with Elize watching over him. She offered soup and bread, then showed him online news articles. His name, she said, was Adam—a missing boy from Britain whose parents were desperately searching for him, including a video of a couple being interviewed against a foggy Scottish moorland. Christophe insisted they must return him, but Mathéo refused. He recalled a conversation from the dinghy that carried him to France: a boy had told him some parents drugged their children to erase their memories before sending them away. Mathéo concluded his parents had given him away, and he felt no emotion about it—the drugs had ensured he couldn't feel anything for them.

The next morning, Mathéo overheard Christophe and Elize discussing his fate. Elize had researched what would happen if he were returned: he wouldn't go back to his parents but would be placed in a care home with other unwanted children. With their own children, Jerome and Adrienne, away at university, they had room. Without further debate, Adam became part of the Laurent family.

The village was told he was the son of a second cousin who had died, and he was enrolled in school as Mathéo. Jerome and Adrienne were told the truth and welcomed their new younger sibling. Mathéo proved a keen student, worked in the vineyards, and chose the family business over university. He never resented his biological parents nor pined for them—he considered what they'd done the greatest of favours.

Christophe and Elize kept a distant watch on Zoe and Dimitri. When they learned the couple had joined The Family Experiment, they told Mathéo, but one episode failed to hold his interest. After the series ended and Zoe and Dimitri were exposed for selling their son, Mathéo streamed the finale alone. Listening to Hudson's account of that night at sea, he realized Hudson was the boy who had saved his life when they jumped overboard. He hated that Hudson had carried guilt all those years, believing Adam had died.

Mathéo readily agreed to put images of missing British children on the winery's wine labels. But he refused to appear on screen with Gabriel Macmillan, the charity's ambassador and Family Experiment contestant. The risk of being recognized as an adult and exposing his family for not returning him as a child was small but real.

The chapter closes with Mathéo finishing his hot chocolate and returning to work. He has no curiosity about his origins. The grass isn't greener elsewhere, he reflects—it's greener in the hills and vineyards around him, his second chance at life.

Character Development

Mathéo — The chapter reveals the full arc of his life: from a trafficked, drugged child with no memories to a contented adult who has built a life on his own terms. His indifference to his biological parents is striking—not born of anger but of the emotional erasure they inflicted. His gratitude to Christophe and Elize is evident in his dedication to the family business. His caution about appearing on screen shows a protective instinct toward his new family.

Christophe — His compassion is the catalyst for everything. He rescued a stranger's child on instinct, suspected trafficking, and chose to raise him rather than hand him to the system. His decision to keep a distant eye on Zoe and Dimitri shows ongoing concern for Mathéo's welfare.

Elize — She researched the consequences of returning Mathéo and advocated for keeping him. Her nurturing presence—the soup, the quilt, the gentle explanation—contrasts with the coldness of Mathéo's biological parents.

Hudson (indirectly) — Though not present, Hudson's guilt is revealed through Mathéo's perspective. Mathéo's hatred of that burden shows his empathy and reframes Hudson's actions as heroic rather than tragic.

Themes, Symbols, or Motifs

Found family — The Laurents are the emotional core of the chapter. Christophe and Elize choose Mathéo not out of obligation but out of love, and Mathéo reciprocates through his work and loyalty.

Memory erasure — The drugging of children to erase their pasts is a chilling motif. It explains Mathéo's lack of connection to his origins and raises questions about identity when memory is stripped away.

Second chances — Mathéo's reflection that the grass is greener on his side of the fence crystallizes the theme. His second chance at life is not just survival but flourishing.

Secrecy and risk — Mathéo's refusal to appear on screen highlights the ongoing risk of exposure. His family's decision to keep the truth from the village is a quiet, sustained deception.

Human trafficking — The chapter grounds the novel's darker themes in the reality of child trafficking from the UK to France, giving weight to the missing children initiative.

Why This Chapter Matters

This chapter is the payoff for a mystery that has run through the novel. It reveals that the boy Hudson believed he failed to save actually survived, and it recontextualizes Hudson's guilt as misplaced. It also completes the story of Zoe and Dimitri's actions by showing their long-term consequences from the perspective of the child they sold. Mathéo's decision to put missing children's images on wine labels ties the personal to the systemic, suggesting that awareness can emerge from tragedy. The chapter also deepens the novel's exploration of what makes a family—biology or choice.

Study Questions and Answers

1. How does the chain of coincidences in Mathéo's rescue function in the narrative?

The chapter emphasizes that Mathéo's survival depended on a series of improbable events: a sick colleague, an uncharged van, a cigarette break, a glance in the right direction. This suggests that fate or chance plays a significant role in the novel's world. It also underscores how easily a child's life could have been lost—and how the difference between tragedy and salvation can be a matter of seconds. The narrative uses this to heighten the stakes of the trafficking storyline and to make Mathéo's gratitude feel earned.

2. Why does Mathéo refuse to appear on screen despite supporting the missing children initiative?

Mathéo's refusal is rooted in self-protection and family loyalty. He recognizes that appearing on screen carries a small but real risk of being recognized as the adult version of the missing boy Adam. Exposure would reveal that Christophe and Elize never returned him to authorities, potentially implicating them in a decades-old decision. His choice shows that his commitment to his found family outweighs the cause he supports—and that the secrecy surrounding his identity remains a live concern even in adulthood.

3. What does Mathéo's indifference toward his biological parents reveal about the novel's treatment of family?

Mathéo's lack of emotion toward Zoe and Dimitri is not a failure of feeling but a consequence of the drugs they administered. The chapter suggests that family is not defined by blood but by the bonds people choose to form. Mathéo's parents erased his memories and sold him; Christophe and Elize rescued him, raised him, and gave him a purpose. His indifference is therefore not coldness but a rational response to being treated as a commodity. The novel uses his story to argue that found family can be more meaningful than biological ties.
