Chapter Twenty-One: Suspicions in Plain Sight

Spoiler Notice

This summary details the events of Chapter Twenty-One of Don’t Let Him In. If you haven’t read this far, you may wish to turn back now.

Summary

Nick arrives on Saturday afternoon bearing fresh flowers, just as the previous bouquet is starting to wilt. Nina tosses the old stems into the bin, washes the vase, and refills it—all while laughing at Nick’s jokes in a noticeably flirtatious, girlish manner. Ash sits at the kitchen table, pretending to work on her laptop, and watches the pair. Nick, leaning against the kitchen counter with the ease of someone who already knows the house, offers unsolicited flower-arranging advice and reveals he once worked in floristry. He jokes that he can curl ribbons with scissors, and Ash, though she smiles, thinks she wishes he would drop the relentless niceness.

Later, when the two adults retreat to the living room, Ash is alone with Nick’s coat. She listens for voices, then moves quickly to search the pockets. In one she finds a tissue, a fifty‑pence piece, a pen, and a small plastic circle printed with a ladybird, attached to blue nylon with a clasp—something she can’t identify. She photographs it. In another pocket, she discovers a slithery dog poo bag, which surprises her: she had no idea Nick owned a dog, and she wonders who cares for it when he visits Nina.

Nick walks back into the kitchen for crisps and makes Ash jump. After he retrieves the snacks, Ash seizes the moment and asks whether he ever met her father’s girlfriend from the 1990s. Nick pauses, then says no—he must have had a few girlfriends, but Nick never met her. When Ash presses, explaining that her father only ever had two girlfriends and that this previous one, Jane, was all‑consuming, Nick claims he worked with Ash’s father for only a handful of months and would not have known Jane. Ash doesn’t voice her disbelief; she knows Jane was constantly present, phoning the restaurant repeatedly and waiting out the shifts. Nick taps the counter, his smile now uncertain, and leaves the room.

Key Events

Nick arrives with a fresh bouquet, and Nina acts coquettish as she tidies the old flowers.
Nick mentions his floristry background and ribbon‑curling skills, charming Nina and annoying Ash.
Alone in the kitchen, Ash goes through Nick’s coat pockets with a quick, furtive search.
She finds and photographs a mysterious ladybird‑adorned plastic item, then discovers a dog poo bag.
Nick re‑enters unexpectedly, startling Ash.
Ash questions Nick about her father’s former girlfriend Jane; Nick denies ever meeting her and downplays the length of his friendship with her father.
Nick exits with crisps and an uncertain smile, leaving Ash’s suspicions deeper than before.

Character Development

Ash moves from passive observation to active sleuthing. Rifling through Nick’s coat shows her distrust has escalated into a deliberate search for evidence. Her quick recovery when caught and her pointed questions about Jane demonstrate her growing refusal to accept the neat version of Nick her mother believes in.
Nina appears giddy and almost school‑girlish around Nick, laughing at his jokes and performing small domestic tasks with exaggerated flair. Her behaviour signals a blind spot—she is entirely seduced by Nick’s charm, which makes Ash’s caution stand out.
Nick continues to project affable competence (floristry skills, intimate knowledge of the kitchen), but the chapter chips away at his veneer. The dog poo bag suggests a life detail he hasn’t shared; his answer about Jane is vague and seemingly dishonest, given what Ash knows. The uncertain smile at the end betrays a crack in his polished surface.
Jane (mentioned) gains texture through Ash’s memory. Although she does not appear, the chapter reinforces that she was an obsessive presence in Ash’s father’s life—a fact Nick curiously fails to recall.

Themes, Symbols, or Motifs

Hidden Identities: Nick’s coat becomes a literal container of secrets. The ladybird trinket and the dog poo bag are small but jarring tokens of an unseen world, reinforcing the idea that Nick presents a curated, incomplete version of himself.
Domestic Masks: Nick’s floristry skill and gift‑wrapping banter function as a perfect “nice guy” costume. Ash’s irritation with his niceness hints that excessive charm can be a red flag rather than a reassurance.
Female Intuition and Surveillance: Ash’s decision to photograph the ladybird object and her restrained interrogation mirror a larger theme of women trusting their gut—and collecting evidence—when something about a man feels off.
The Unspoken Pet: The dog poo bag introduces the mystery of a dog Ash knows nothing about, suggesting Nick keeps whole swathes of his life concealed from Nina and Ash.

Why This Chapter Matters

Chapter Twenty-One marks a turning point in Ash’s investigation. No longer just nursing vague unease, she actively gathers physical clues and tests Nick’s story. The items in his coat are tangible evidence that he is not being forthright, while his denial about Jane directly conflicts with Ash’s well‑established family history. The chapter crystallises the central tension: Charm is Nick’s weapon and he wields it so effectively that only Ash sees the cracks. By the end, the reader shares Ash’s certainty that something is deeply hidden, and the stakes for uncovering the truth have risen sharply.

Study Questions and Answers

What suspicious items does Ash discover in Nick’s coat pockets, and why do they trouble her?
Ash finds a plastic ladybird charm attached to blue nylon—an object she cannot identify—and a dog poo bag. The ladybird trinket is alien enough to arouse curiosity, but the dog bag startles her because she had no idea Nick owned a dog. Its presence implies he hides mundane but meaningful aspects of his life from Nina and Ash.
How does Nick respond when Ash asks about her father’s former girlfriend Jane, and what is significant about his answer?
Nick hesitates, then says he never met Jane. He also downplays his time working with Ash’s father, claiming it lasted only a few months. This contradicts Ash’s knowledge that Jane was omnipresent—she waited out shifts and phoned the restaurant constantly. His evasion suggests either a conveniently selective memory or outright dishonesty, deepening Ash’s mistrust.
In what ways does this chapter continue the novel’s exploration of hidden danger lurking behind a friendly facade?
Nick’s flowery charm, domestic competence, and warm smiles all contribute to the perfect‑gentleman image that enchants Nina. Yet Ash’s covert search and the odd items she finds peel back that surface to hint at a carefully managed identity. The chapter reinforces the idea that the most dangerous people can be the ones who refuse to let you see what is in their pockets—literally and figuratively.
