Summary

In Chapter 31, the narrator (Grace) shows Alberto a photograph from the website featuring a St Christopher necklace. Alberto insists she must see something that will change her life, but she resists the idea of change. He suggests that moving to Ibiza and living in the house given by a near-stranger already proves she wants transformation. Grace retaliates by stating she was a maths teacher who values logic; she wants to know how Christina van der Berg died. Alberto flinches at the full name and reveals that Christina knew she would be killed and therefore took action. He mentions he was in Madrid with his daughter Marta, an astrophysicist and environmentalist organising a protest against development on Es Vedrà. Alberto tells Grace that Christina was a skilled diver who sometimes went out alone. He then claims Grace is ready to see the truth and has “potential.” Frustrated by his evasiveness, Grace demands plain answers. Alberto responds that if she wants to stay normal she should leave, but a moonless night tomorrow offers a chance to understand what happened to Christina. He invites her to join him for a midnight dive between Ibiza and Formentera. Grace protests her age (72) and inexperience with diving, but Alberto dismisses her objections. As he turns to leave, Grace feels a pull to follow him despite warnings from Sabine, Rosella, and the Guardia Civil. Alberto reiterates the appointment at midnight and departs, leaving Grace exhaling as if for the first time in twenty minutes.

Character Development

Grace (the narrator) – Throughout the chapter Grace oscillates between scepticism and a desperate need for answers. Her identity as a former maths teacher grounds her in logic, yet she finds herself drawn to the irrational allure of Alberto’s cryptic promises. Her sarcasm (“I am seventy-two years old. I don’t do midnights.”) reveals a self-awareness about her age, but Alberto’s persistent confidence chips away at her resistance. The chapter ends with her exhaling in relief, suggesting she has made a decision to trust (or at least test) the path Alberto offers.

Alberto Ribas – Alberto is portrayed as an enigmatic, almost pirate-like figure whose laugh is too large for its prompt. He speaks in riddles, lectures on Iggy Pop and Es Vedrà, and treats Grace’s potential as a foregone conclusion. His knowledge of Grace’s living situation indicates he may have been informed by Christina (or others), yet he insists on showing rather than telling the truth. His paternal side emerges when he speaks proudly of his daughter Marta. Despite his oddness, he does not seem malevolent, though the Guardia Civil’s warning (“Please stay away from Mr Ribas”) lingers in Grace’s mind.

Themes, Symbols, or Motifs

  • Curiosity and Risk – The proverb “curiosity killed the cat” appears explicitly. Grace’s curiosity drives her to ignore warnings (from Sabine, Rosella, the police) and accept a midnight dive with a stranger. The risk of the unknown is weighed against the promise of knowledge.
  • Age and Capability – Grace uses her age (72) as a reason to decline, but Alberto counters with the example of a ninety-year-old dancing at Pacha every night. The motif of age as a limit is challenged; Ibiza is presented as a place where age is irrelevant.
  • Truth vs. Show – Alberto insists that some things “can’t be told. They have to be shown.” This idea recurs throughout the chapter, framing the coming dive as a revelation rather than an explanation.
  • The Sea and Diving – The ocean between Ibiza and Formentera becomes a threshold to hidden knowledge. Diving is described as “swimming but down,” a literal descent into the unknown. The moonless night adds secrecy and danger.
  • The St Christopher Necklace – The photograph at the chapter’s opening links to an earlier mystery, connecting Christina’s possession to Alberto’s knowledge.

Why This Chapter Matters

Chapter 31 is the pivotal moment when Grace transitions from passive inquiry to active, risky commitment. Alberto’s invitation to the midnight dive crystallises the central mystery: what really happened to Christina van der Berg. The chapter also deepens Alberto’s character, showing him as both a father and a keeper of secrets. By accepting the invitation (or at least considering it), Grace steps beyond her safe, logical life and embraces the “impossible” possibility that truth may be hidden in the sea. This sets the stage for the climactic events of the next chapter.

Study Questions and Answers

  1. What does Grace’s sarcastic response “I am seventy-two years old. I don’t do midnights. Or diving” reveal about her state of mind?
    Grace uses her age and past lifestyle as a shield against Alberto’s pressure, but the sarcasm also masks her fear and curiosity. She is trying to maintain control, yet she is already intrigued enough to continue the conversation.

  2. Why does Alberto say “some things can’t be told. They have to be shown”?
    Alberto implies that the truth about Christina’s death is not a simple fact but an experience. This matches his cryptic behaviour throughout the chapter—he wants Grace to witness something directly rather than receive a verbal explanation. The line also establishes the dramatic stakes for the midnight dive.

  3. How does the mention of the Guardia Civil’s warning affect the reader’s perception of Alberto?
    The warning (“Please stay away from Mr Ribas”) adds an element of danger and suspicion. Combined with Alberto’s odd manner and evasiveness, it makes him an ambiguous figure. However, his knowledge of Christina and his relationship with Marta hint at a more complex, possibly trustworthy character. The tension between these two views drives the chapter’s suspense.
