Summary

This chapter is a flashback set six months before the main narrative. It opens with Erin telling Arlo she is thinking of leaving the Triskele. Arlo turns over in bed, with their nine-month-old daughter Freya between them. Erin says she no longer feels the same about the group, and Arlo agrees it feels less fun and more like being told off.

The previous weekend, they had asked Clem to babysit while they attended a meeting in the Trossachs. The Brother pressured Erin to run an art workshop despite her explaining that Freya was still feeding through the night and she felt ragged. He brought up the scholarship and her indebtedness to him, and claimed her monthly payments did not even cover the basics. Erin reflects bitterly that she was handing her maternity pay to a man who did not work but somehow drove a Land Rover. She suspects the workshop request was really about making her feel part of something, since she had missed nine meetings because of the baby.

At that meeting, Erin barely recognized the Brother. He had shaved off his long hair and beard, lost a great deal of weight, and looked haunted, with dark circles under his eyes. She wondered if he had a terrible illness. He spent two hours shouting at the whole clan, calling them blind, stupid, and lazy, and warning they would be punished. Erin then stood at a table under a shoddy gazebo teaching new recruits to make posters while her body ached and her breasts filled with milk. Her own poster read "protect me from what i want," and she realized she was telling herself something.

Arlo says he will leave too. Erin protests that he does not have to, but Arlo admits he has wanted to leave since she told him Freya was definitely his—he only stayed because he thought she wanted to remain. Erin then says the Triskele is a cult, and feels relieved to say it out loud. She recalls that Senna made a big deal about how it was not a cult when Erin first joined. Erin admits she wanted to be part of something, wanted a family, but the Triskele was not it—Arlo and Freya were.

Erin says she wants to give back the book, which is creeping her out. She thinks back to meeting the Brother at the derelict castle in the Trossachs, where he convinced her to keep the baby and pressed the book on her. Since then she has felt haunted—terrible whisperings in her head, her bones, and her heart. Months earlier, she woke up to find herself standing over her mother with scissors in her hand, imagining thrusting them into the soft flesh between her jaw.

Later that morning, while Arlo takes Freya in the stroller to the corner shop, Erin messages the Brother on WhatsApp. He does not reply, so she messages the Triskele group chat, now over two hundred members. Rodge responds that seeing the Brother is not possible, and the chat fills with confused emojis and messages. Rodge then videocalls her from work, where supermarket shelves are visible behind him. He tells her the Brother is dead—suicide on Monday night. He mentions there will be a shift in how the group works, then hangs up when a colleague interrupts. Erin tries to tell him she wants to give the book back, but it is too late.

Erin is stunned by the news. She pulls the shoebox from under her bed and takes out the book, shaking, with bile rising in her throat. Sometimes she feels the book's presence in her room like another person, an energy coming off it as though it has thoughts. But today it is just a book—ugly, with old bark, bits of lichen falling off, and a fresh shoot poking out from the spine as though it is still growing. She opens it and looks at the black pages, which feel like fine charcoal paper but leave no marks on her fingers.

She puts the book back in the shoebox. Hearing the rumble of a bin lorry, she runs downstairs and throws the shoebox into the back, delighted to see it tumble among the trash. She watches the lorry pull away. Arlo returns with Freya asleep in the pram, kisses her, and they head home—where the book will be waiting on the bed, fully intact, as though she never threw it away at all, its shadows and whispers as inescapable as ever.

Themes, Symbols, or Motifs

Cult control and leaving: Erin's recognition that the Triskele controls everything members do, and the difficulty of extricating oneself, is central. Her relief at naming it a cult marks a turning point.
The book as living entity: The book has a presence like another person, an energy as though it has thoughts. It grows—a fresh shoot pokes from its spine—and it resists disposal, returning to Erin's bed intact.
Motherhood and sacrifice: Erin's exhaustion from night feeding, her aching body during the workshop, and her maternity pay flowing to the Brother all illustrate the costs of her situation.
Guilt and self-protection: The scissors episode and the poster's message reveal Erin's fear of her own impulses and her need for protection from what she wants.
Desire for belonging: Erin wanted a family and a sense of being part of something; she finds it in Arlo and Freya rather than the cult.
The book's return: The motif of inescapability—the supernatural resisting human attempts at freedom—closes the chapter with a note of dread.

Why This Chapter Matters

This flashback chapter provides essential backstory for Erin's relationship with the Triskele and the book. It establishes the book's supernatural nature—its ability to return after disposal—and explains Erin's motivations for leaving the group. The Brother's suicide is a major plot development that reshapes the group's dynamics, as Rodge's mention of a shift in how the group works suggests. The chapter also deepens the horror: the book is not merely an object but a persistent, growing entity that cannot be discarded by ordinary means, foreshadowing the challenges Erin will face in the main timeline.

Study Questions and Answers

1. Why does Erin decide to leave the Triskele, and what does her poster reveal about her state of mind?

Erin leaves because the group has become controlling and demanding—the Brother pressures her to run workshops despite her exhaustion, and she recognizes the cult's control over members' lives. Her poster "protect me from what i want" reveals her internal conflict: she wanted belonging and family, but the Triskele offered a distorted version of that, and she needs protection from her own desires and the group's manipulation.

2. How does the chapter establish the book as a supernatural entity rather than a mere object?

The book is described as having a presence like another person and an energy as though it has thoughts. It has a fresh shoot poking from its spine as though still growing, and its black pages feel like charcoal paper but leave no marks. Most significantly, it returns to Erin's bed intact after she throws it into a bin lorry, demonstrating that it cannot be disposed of by ordinary means.

3. What does Arlo's confession reveal about his character and his relationship with Erin?

Arlo reveals he has wanted to leave the Triskele since learning Freya was his daughter, but stayed only because he thought Erin wanted to remain. This shows his loyalty and commitment to Erin and Freya, and his willingness to subordinate his own desires to hers. It also strengthens the bond between them, as Erin realizes Arlo and Freya are the family she truly wanted.
