Daisy Darker – Chapter 22 Summary & Analysis

⚠️ 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

The chapter opens at 2:30 a.m., less than four hours before low tide. Rose discovers Trixie locked inside the cupboard under the stairs and gently pulls her out. After checking for a pulse, Rose confirms Trixie is alive but unconscious. Lily panics and demands to know who hurt her daughter. Rose notices a small amount of dried blood between Trixie’s toes and hypothesizes that someone injected her with insulin. Lily insists Nancy could not have done such a thing, but Rose counters that Nancy’s diabetic kit is missing its insulin pen.

Rose pricks Trixie’s finger to test her blood sugar, then retrieves a vial of glucagon from her own leather bag—a gift from Nana when Rose started veterinary studies. She injects Trixie with the glucagon, and Trixie revives, crying for her mother. The family moves to the lounge, barricading the door with a chair. Trixie recalls only drinking tea (dosed with a sleeping pill) and waking up in the hall. Daisy reflects on the earlier dinner conversation where Rose joked about injecting insulin between the toes to commit murder—a technique someone has now used.

The power suddenly returns. As Rose packs her bag, Trixie notices a handgun inside. Lily questions why Rose has the gun; Rose explains that vets sometimes need them to euthanize suffering animals. Rose leaves to fetch the key from the cupboard door, planning to lock the lounge until low tide. Conor follows her, and they discuss the murders. Conor suspects the killer is after a secret Nana intended to reveal in her final novel. He notes that the bodies of Nana and Frank were found in the cupboard, explaining why the dog Poppins had been scratching there. Rose locks the cupboard and returns to the lounge. Daisy, eavesdropping, feels increasingly uncertain who to trust, fearing more killings will follow.

Character Development

Daisy: Becomes a passive observer, hiding in doorways and piecing together fragments. Her narration reveals growing paranoia and a loss of certainty about whom she can trust.
Rose: Takes command in a crisis, using her veterinary training to save Trixie. Yet the discovery of the gun and her evasive answers make her appear more ambiguous. She admits to keeping secrets.
Lily: For the first time appears vulnerable and frightened, dropping her tough exterior when Trixie is in danger. Her maternal instincts override her usual defensive arrogance.
Conor: Theorizes about the killer’s motive—protecting a secret from Nana’s novel—and links the bodies in the cupboard. He positions himself as a co-investigator, though his own role remains unclear.
Trixie: Shows resilience but also sharp intuition, questioning Rose about the gun. Her innocence contrasts with the escalating violence.
Nancy: Absent and suspected, though the chapter keeps her fate ambiguous.

Themes, Symbols, or Motifs

Insulin as a weapon: The dinner-table hypothetical becomes brutal reality, underscoring the theme of family malice disguised as casual talk.
The cupboard under the stairs: Both a storage space of childhood memories (height marks) and a tomb for the dead. It symbolizes repressed family history and the hidden bodies of secrets.
Light and power: The return of electricity after the attack on Trixie offers a fleeting sense of safety, but the characters remain trapped physically and emotionally in darkness.
Trust and surveillance: Daisy watches from doorways, Conor and Rose speak in hushed tones, and Trixie’s questions expose hidden objects. No one is fully transparent.
Euthanasia language: Rose’s explanation of the gun (“if an animal is in pain”) foreshadows a potential mercy killing or comfortable lie to cover murder.

Why This Chapter Matters

Chapter 22 marks a turning point: the killer has now attacked a child, raising the stakes and making the need for escape dire. It confirms that the murder method (insulin injection) was foreshadowed earlier, tightening the plot’s internal logic. The discovery of the bodies in the cupboard provides a concrete clue about the killer’s disposal method. Rose’s possession of a gun and her veterinary knowledge make her both a protector and a suspect. The chapter ends with Daisy’s dread that the killings are not finished, setting up a race against time before low tide allows escape.

Study Questions and Answers

Why does Rose use glucagon rather than another substance to treat Trixie?
Rose suspects Trixie was injected with insulin, which can cause dangerously low blood sugar. Glucagon raises blood glucose and is a standard antidote for insulin overdose. Rose has glucagon because it is also used in veterinary medicine for the same purpose.
What does the conversation between Conor and Rose reveal about the killer’s possible motive?
Conor believes the killer is silencing a secret that Nana planned to expose in her final novel. He speculates the killer also trashed Nana’s studio looking for that manuscript. This suggests the murders are not random but targeted to prevent the family’s hidden truths from being published.
How does Daisy’s role as narrator change during this chapter?
Daisy shifts from being a semi-participant to a covert observer. She follows Conor and Rose, eavesdrops on their private conversation, and reflects on her own confusion. This positions her as an unreliable yet keen witness, highlighting the theme that no one can be trusted.
