Chapter 10: Four Years Earlier – Summary & Analysis

⚠️ Spoiler Notice

This analysis contains complete plot details from Chapter 10 of Don't Let Him In. If you haven’t yet read the chapter and want to experience its chilling revelations firsthand, turn back now.

Summary

The chapter opens with an unnamed first-person narrator leaving the train station, where he spots a wide-eyed, elfin woman. Once intimidated by such women, he now feels only a condescending thrill at their vulnerability. He deliberately walks too closely behind her, matching her pace, and revels in the scent of her fear. The encounter energizes him, and he arrives home ready to have sex with his wife, performing an act of tenderness that masks his true arousal from the earlier stalking.

Afterward, his wife asks what prompted the passion, and he lies smoothly about thinking of her all day. He muses with contempt about how easily women are satisfied, and how most men fail to exploit that. Over dinner, he manipulates his wife into accepting his fabricated last-minute work trip to Edinburgh that will cancel the drinks party she had been looking forward to. Using feigned glassy eyes and a story of a childhood dog, he reasserts control just as her anger begins to surface, and she relents.

The narrative reveals they married three years ago after a six-month courtship, in a low-key ceremony that her adult children and few others attended. Her mother has died, and her best friend Fleur has faded from her life. Her children, especially her pregnant daughter Emma, distrust him, but that does not matter; what matters is his wife’s absolute trust. He has her passwords, access to her phone, and total surveillance of her existence, while he keeps his own life carefully compartmentalized.

After dinner, he retrieves a doctor’s bag—his father’s—from beneath the wardrobe, opens a hidden pocket, and powers on a secret phone. He texts Martha, his mistress, confirming he is free for the coming weekend. Her reply is instantaneous: she is besotted, and the children will be with her ex. He admires his reflection, noting his still-good looks for nearly fifty-one, and reflects on Martha’s charms: she is younger, pert, financially independent, and believes she doesn’t need a man—but her rapid blue ticks betray her addiction to him. The chapter ends with him sending a single red-rose emoji and thinking, See you on Thursday, beautiful Martha. I cannot wait.

Character Development

The Unnamed Narrator (Husband)
This chapter strips away any external charm to reveal the narrator’s predatory and manipulative core. He objectifies women, relishes their fear, and systematically gaslights his wife with practiced sincerity. His reflections on the “Bambi girl” expose a power dynamic where he conflates terror with arousal. The careful retrieval of the secret phone and the cold assessment of Martha as someone he has made “addicted” to him demonstrate a chilling, calculated narcissism. He sees relationships as games he must win by any method available.

Tara (Wife)
Tara appears only through the narrator’s contemptuous lens, but her reactions hint at suppressed strength. She momentarily challenges him over the canceled party, her face changing color with anger, before his manipulation dissolves her resistance. The detail that her children don’t like him and that her friend Fleur has disappeared suggests she has become increasingly isolated—a classic sign of coercive control. Yet her prior enthusiasm for the party shows a latent desire for connection outside the marriage.

Martha (Mistress)
Martha is portrayed as an independent woman who didn’t think she needed a man, now thoroughly enthralled by the narrator’s calculated charm. Her instant replies and the “haste wax” detail underscore her eagerness and unconscious vulnerability. The narrator’s observation that she dresses up her children’s absence for him reveals her quiet desperation to please, setting her up as another puppet in his emotional scheme.

Themes, Symbols, or Motifs

Manipulation and Control
Every interaction the narrator has is a performance designed to control others. He orchestrates his wife’s emotions with a rehearsed “glassy eyes” trick, times his revelations to weaken her resistance, and even chooses the lighting so he can view her as “pretty.” The motto that women are “so easily pleased” frames his entire worldview as one of strategic exploitation.

Duality and Deception
The secret phone hidden inside a doctor’s bag—itself a symbol of his father’s respectable legacy—epitomizes the split between his public persona of perfect husband and his private life as adulterer and predator. The bag’s layers of compartments mirror his own “compartmentalized” existence.

Power and Fear
The opening scene equates fear with a “quick, cheap thrill.” The narrator’s power comes not from strength but from making women feel unsafe. He no longer lusts after the elfin girl; he lusts after the power her discomfort gives him. This transference of terror into sexual energy becomes the engine of his abusive dynamics.

Gaslighting as Domestic Ritual
The drinks party cancellation scene models textbook gaslighting: he makes his wife doubt her legitimate anger by performing exaggerated guilt and redirecting her focus to a future “quality life” that will never materialize. Her final sigh and capitulation show the erosion of her sense of reality.

Why This Chapter Matters

Chapter 10 marks the first time the narrative dives fully into the husband’s perspective, unmasking the villain behind the earlier mystery. By choosing first-person, Lisa Jewell forces the reader into an uncomfortable complicity with a man who gamifies relationships and exploits trust. The chapter establishes the foundational dynamic of the entire novel: the narrator’s dual life, the systematic isolation of his wife, and the existence of a secret mistress. The hidden phone and the doctor’s bag become crucial Chekhov’s guns that will undoubtedly resurface. Moreover, the cold revelation that he finds arousal in a stranger’s fear reframes all prior scenes with a sinister undertone, alerting the audience that no interaction with this man is ever innocent.

Study Questions and Answers

1. How does the narrator use the “Bambi girl” incident to manipulate his wife?
She never learns of it. Instead, the predatory thrill becomes transmuted into sexual energy that he directs at his wife, performing a passionate intimacy that makes her feel specially desired. That false intimacy deepens her trust and makes his later lie about the work trip more palatable. The encounter also showcases his ability to convert even a random act of intimidation into a tool for domestic control.

2. What does the doctor’s bag symbolize, and why is it significant?
The bag belonged to his father, a GP, linking it to a legacy of respectability and care. By using it to hide a secret phone and an entire hidden life, the narrator perverts that legacy. The bag’s nested compartments symbolize his own layered deceptions: each layer opened reveals another, and the innermost secret—the phone—represents the core truth he guards at all costs.

3. Why does the narrator resent Martha’s independence, even as he pursues her?
He explicitly notes that Martha thinks she doesn’t need a man. His goal is not to love her but to make her need him irrationally, to “light” something inside her so she will be terrified of losing him. Her professional success and social life are challenges he must dismantle; each blue tick that appears instantly is a victory. This resentment of female autonomy reveals the misogyny that fuels all his relationships.
