One of Us Summary (Spoilers Ahead)
Martin Gilmour is a scholarship boy who attached himself to Ben Fitzmaurice at Burtonbury School and never fully left.
Now an art history lecturer at the University of South Anglia, he’s forced into therapy after using the term “orientalism” in class. A black-edged invitation arrives: Fliss Fitzmaurice, Ben’s rebellious sister, has died. The funeral is at Denby Hall.
At the funeral, Martin meets Derek, a friend from Bali who claims Fliss didn’t drown accidentally—she killed herself after being “through hell.”
This contradicts Ben’s eulogy, which blamed addiction. Meanwhile, Serena, Ben’s wife, begins an affair with Andrew Jarvis, a wealthy financier backing Ben’s political career.
She’s motivated by Ben’s neglect and his infidelity with her friend Violet.
Richard Take, a disgraced MP rebuilding through reality TV, attends hoping to align with Ben’s leadership bid.
Cosima, Ben and Serena’s daughter, arrives late—she’s been at an environmental protest where her lover River was injured. She doesn’t yet know River is an undercover police officer.
The truth emerges slowly. Fliss was raped by Jarvis. She told Ben. He dismissed her, citing her “unreliable” history and her previous claims about their grandfather abusing her.
Ben needed Jarvis’s money for his campaign, so he bribed two senior detectives to make the files disappear. Fliss fled to Bali and eventually walked into the sea.
Cosima receives encrypted files from River. She gives them to Martin, who gives them to Richard Take.
Advised by his ex-wife Hannah to “burn the fuckers down,” Richard goes on live television, exposes the cover-up, and announces his own leadership bid. Ben and Jarvis are arrested.
Eighteen months later, Ben is in Belmarsh, working as a prison librarian. He’s apologized to Martin, who now has a loving partner named Alexander and a successful book.
Richard is Prime Minister. Jarvis, charges dropped due to lack of evidence, walks free. The final image: Martin at a luxury hotel, watching Jarvis approach by the pool. The predator never truly disappears.

One of Us Ending Explained
⚠️ May contain spoilers.
The ending refuses easy catharsis. Ben goes to prison but adapts—finding purpose as a librarian, performing humility so convincingly he may believe it himself.
Richard Take becomes Prime Minister, but his ascent required leaked files and a reality TV redemption arc.
Martin finally achieves belonging through Alexander and a successful book, but the price was destroying the man he spent forty years loving and hating.
And Jarvis walks free. His wealth protects him.
The final image—Martin spotting him by the pool—suggests the system that protects predators remains intact. One snake beheaded, another still slithering.

One of Us Book Review
Themes Analysis
Class and the Insularity of “Us”: The title’s central question—who counts as “one of us”—haunts every page. Martin spends forty years trying to breach a wall that Jarvis later names explicitly: “He will never be one of us.” The novel argues that class isn’t about money but about belonging so innate it requires no performance.
Loyalty as a Weapon: Ben expects Martin’s silence after a fatal car crash. He expects Serena’s silence after Fliss’s rape. Loyalty isn’t reciprocal in the Fitzmaurice world—it’s a one-way street where the powerful collect debts and the loyal pay interest forever.
The Erasure of Women’s Truth: Fliss tells Ben about the rape. He dismisses her because she’s “unreliable.” Serena tells Ben about Jarvis’s predatory nature. He ignores her. The novel shows how women’s testimony disappears when it threatens male power structures.
Political Performance: Every character performs constantly. Ben performs grief at Fliss’s funeral. Richard performs authenticity on reality TV. Even Martin performs the role of grateful scholarship boy. Day suggests there’s no authentic self left when power is the goal.
Revenge as Intimacy: Martin notes that “revenge is a lot like love” because it requires knowing someone completely. His decades-long observation of Ben becomes the tool of Ben’s destruction.
Generational Trauma: The Fitzmaurice children—Ben, Fliss, Magnus—were raised by a grandfather who abused Fliss and a system that protected him. The novel traces how trauma passes down even through silence.
Justice as Commodity: Jarvis walks free because he’s wealthy. Ben goes to prison but finds peace as a librarian. The system isn’t broken—it’s working exactly as designed.

Literary Breakdown & Review
I’ve read Day’s entire bibliography, and this may be her most ambitious work. Here’s what I noticed.
Opening (or Hook)
⚠️ Alert: May contain minor spoilers.
The novel opens with Martin mocking his therapist’s “banal aphorisms,” establishing his cynical, self-protective voice immediately
We learn about the “orientalism” incident that forced him into therapy—a perfect microcosm of how performative social justice collides with actual power
Writing Style & Language
Day’s prose is sharp enough to draw blood; every sentence carries weight
She uses sensory language to create physical repulsion—Jarvis’s “fusty onions” sweat, Serena’s “crepey” skin, the “phlegmy cough” of political advisers
The voice shifts subtly between narrators while maintaining cohesion
Narrative Voice & POV
Multiple first-person perspectives create a Rashomon effect—the same events (the car crash, Fliss’s death) look different through each character’s self-interest
Fliss’s posthumous chapters are ethereal, heartbreaking counterpoints to the living characters’ scheming
Martin’s voice is the most developed—a “hall of mirrors” where you’re never sure which reflection is real
Dialogue & Character Voice
Day captures class through cadence: Ben’s “dazzling” bonhomie, Serena’s “glacial detachment,” the “business-speak” of university administrators
The therapy scenes crackle with Martin’s internal mockery of language he’s forced to use
Jarvis speaks like someone who’s never been told no
Structure (POV, Timelines, Case vs Personal Arc)
Part One (The Funeral) establishes the world and characters; Part Two (The Takedown) accelerates toward destruction
Fliss’s interstitial chapters provide emotional grounding—we know she’s dead, but we hear her voice
The “Eighteen Months Later” epilogue offers closure while maintaining cynicism
Pacing & Rhythm
The first half moves deliberately, using clinical diets and political podcasts for social satire
Once the “files” appear, Part Two becomes a thriller
The final image—Jarvis walking toward Martin—lands like a punch
My Final Rating: 4.4/5 stars ★★★★☆

Conclusion
For anyone who has ever wondered about the deals made in rooms they’ll never enter, the women silenced by systems designed to protect men, or the cost of belonging to something that was never truly yours—One of Us offers no easy answers, but it offers something better: the sense that someone else has asked the same questions.
The final image—Jarvis walking toward Martin by the pool—says everything. The snake may be beheaded, but the garden still holds predators.
The question isn whether they exist. It’s whether we’ll keep looking away.
