About the author: Who is Sally Hepworth?

Sally Hepworth is an Australian author with ten novels and millions of copies sold worldwide, published in over 25 languages. Her books, including 'The Mother-in-Law', 'The Good Sister', 'The Younger Wife', 'Darling Girls', and 'The Soulmate,' sit squarely in the domestic thriller and women's fiction space, praised by Liane Moriarty and Emily Giffin alike.

'Mad Mabel' marks a visible shift in her work. The protagonist is older than any character she's centered before. The emotional undertow is heavier. The backstory involves a court conviction, a psychiatric facility, and six decades of silence.

It's her most ambitious book yet, and most readers who've followed her from 'The Mother-in-Law' onward will feel the difference by the second chapter. Advance copies were made available on NetGalley ahead of the US publication date, where early readers flagged the Daphne reveal as one of the more structurally daring moves Hepworth has made.

'Mad Mabel' book at a glance: Key facts and details

Before getting into the review itself, here are the basics.

The audiobook production from Macmillan Audio is worth noting if you prefer listening. The dual narration between Hannah Fredericksen and Jenny Seedsman maps cleanly onto the Then/Now structure, and the tonal contrast between young Mabel and elderly Elsie lands well in audio format.

'Mad Mabel' book plot summary (spoiler-free)

This section contains no spoilers. The spoiler section is clearly marked further down.

Elsie Mabel Fitzpatrick is 81 years old. She's lived at the end of Kenny Lane longer than anyone, and she plans to die there. She's known on the street as difficult: perpetually suspicious, devoted to her best friend Daphne, and at constant war with Joan, the neighbor who seems determined to document every strange thing Elsie does.

When Ishaan, another neighbor, turns up dead, Joan starts hinting to the paramedics that Elsie has a history worth knowing about. Then a newspaper clipping about "Mad Mabel Waller" appears under Elsie's door, and the life she's built begins to crack.

The novel alternates between "Then" — Mabel's childhood and adolescence in a volatile household run by a manipulative, dangerous father — and "Now" — Elsie's present unraveling, her unlikely bond with seven-year-old Persephone next door, and a podcast team that arrives wanting to tell her side of the story finally.

The central question isn't quite "did she do it?" It's closer to: what does it mean to label a child "mad" before she's had any chance to speak for herself? And what does it cost a person to carry that label for 60 years?

If you liked 'Small Things Like These' for its slow-burn moral weight, or 'The Life We Bury' for the way secrets fracture a present-day story, 'Mad Mabel' will feel immediately familiar in the best way.

📘 Understand the psychology behind Mabel's story; Headway has the nonfiction to back it up.

'Mad Mabel' characters: Who's who on Kenny Lane

The cast here is specific enough that even minor characters carry meaning. Here's who matters and why.

Elsie Mabel Fitzpatrick (Elsie / Mabel)

The protagonist. She's 81, prickly, perceptive, and darkly funny in the way that people are when they've stopped caring what anyone thinks. Her narrative voice is the engine of the novel — caustic on the surface, unexpectedly tender when it matters. Elsie Fitzpatrick renamed herself after her conviction and has lived quietly ever since.

Daphne

Elsie's closest friend and confidante, present throughout the "Now" timeline. Her role in the story is central to the novel's biggest structural revelation. Discussed in full in the spoiler section below.

Persephone (Persy)

The seven-year-old daughter of Elsie's neighbor Roxanne. Their friendship is the emotional anchor of the present-day story — unlikely, warm, and quietly devastating by the end. She mirrors the dynamic between young Mabel and the few adults who once showed her kindness.

Joan

The antagonist of Kenny Lane. She's litigation-prone, suspicious of Elsie, and determined to surface whatever Elsie is hiding. Her motivations grow more complicated as the novel moves forward, and Hepworth resists the easy villain read.

Peter

A kind Greek-Australian neighbor who cares for Elsie quietly and without fanfare. His role carries significantly more weight than it initially appears.

Elliott (Mabel's father).

The central villain of the "Then" timeline. Systematic and specific in his cruelty, emotional, financial, physical, and drawn with precision rather than cartoon menace. He's the character the novel most forcefully indicts.

Aunt Cecily ("Cess") and Ness

The warmth in young Mabel's childhood. Their relationship with each other and with Mabel is the emotional counterweight to everything Elliott represents.

Caro Claire Burke

A secondary character whose presence in the story connects to the podcast storyline and the public narratives that form around Elsie's past. She represents the outside world's appetite for a tidy version of Mabel's story.

The character work here is what separates 'Mad Mabel' from a standard domestic thriller. Hepworth builds Elsie's voice with enough specificity that the "Then" timeline feels like archaeology, you're excavating the person behind the woman on Kenny Lane, piece by piece.

'Mad Mabel' book themes: What this novel is really about

'Mad Mabel' works as a murder mystery on the surface. Underneath, it's a precise and patient argument about who gets to name a person, and what happens when that name sticks for 60 years. These are the ideas Hepworth keeps returning to, chapter after chapter.

The power of labels

The word "mad" gets applied to Mabel by her father before she's done anything wrong. That label spread, to the community, to the courts, to the headline that follows her for 60 years. Hepworth tracks how a label assigned by someone with authority and cruelty can become the defining story of a person's life, regardless of its accuracy.

Female friendship

The bond between Mabel and Daphne is positioned as one of the deepest relationships in the book. Hepworth makes an explicit case for the legitimacy of platonic love between women, resisting any impulse to reframe that closeness as anything other than what it is.

Childhood as context

Young Mabel's choices cannot be understood outside the household she was born into. The novel carefully builds the argument that a child who was never protected cannot be held to the same moral accounting as one who was. This is where the book aligns most closely with what researchers and trauma specialists have documented in cases of wrongful conviction following childhood abuse.

Identity and reinvention

Elsie is not Mabel — or rather, she has spent 60 years constructing herself as not-Mabel. The cost of that reinvention, and what survived it anyway, runs quietly through the whole novel.

Public judgment and media scrutiny

The podcast team that arrives in the present-day timeline wanting to "tell her story" is another form of the same machinery that convicted her as a child. Hepworth uses that framing pointedly.

Loneliness and belonging

From young Mabel's profound isolation to elderly Elsie's fiercely guarded social world, the novel keeps returning to who gets to belong and on what terms.

These themes make the book a strong companion to some of the literary titles covering similar emotional territory, books like 'Then She Was Gone' or 'First Lie Wins' both work through how a person's past shapes every present-day choice they make.

📘 Good books ask hard questions. Headway helps you find the answers.

'Mad Mabel' book review: What works and what to know before you read

Hepworth has always been good at building dread quietly, but 'Mad Mabel' does something she hasn't quite pulled off before, which is making you care so much about a character's interior life that the plot almost becomes secondary. Here's the honest breakdown before you commit.

What the novel does well:

• The dual-timeline structure is handled with real craft. The "Then" and "Now" sections feel like two sides of the same argument, not a gear-change between storylines.

• Elsie's narrative voice is one of Hepworth's finest achievements: acerbic, funny, and unexpectedly tender at the right moments.

• The relationship between Elsie and Persephone earns its emotional weight without becoming sentimental.

• The novel withholds information strategically without feeling manipulative.

• The supporting cast is specific enough that even the most minor characters carry meaning by the end.

What some readers find challenging:

• The pace in the middle section slows considerably as backstory accumulates. Readers expecting a tightly plotted murder mystery may find that the character study does most of the heavy lifting.

• Some details of Mabel's institutionalization and the decades between her conviction and Kenny Lane are lightly sketched, which may leave readers wanting more.

The honest verdict: 'Mad Mabel' is not the fastest thriller Hepworth has written. It's the most emotionally precise. Readers who go in expecting a character study will get everything they came for. If you're here for high-speed plot mechanics, adjust your expectations slightly, and you'll still finish it in two sittings.

For more context on how this fits into the domestic suspense genre, the 'Demon Copperhead' review on the Headway blog offers a useful comparison on how literary fiction handles trauma and institutional failure.

Spoiler warning: Everything below reveals major plot details, including the ending and the Daphne twist

Stop here if you haven't finished the book.

'Mad Mabel' ending explained

If you've finished the book and need to sit with what just happened, you're in good company. The ending works on several levels at once, and some of the reveals only fully land once you trace them back through earlier chapters. Here's everything broken down clearly.

What Mabel actually did

At 15, Mabel discovered her father had murdered her beloved Aunt Cecily ("Cess"). When he tried to frame Mabel for the crime, she killed him — with an umbrella — in an act of self-preservation and fury. She was convicted not cleanly for his murder, but caught in a legal tangle in which her only alibi witness, Daphne, was disbelieved by the court.

The Daphne reveal

Daphne was not a real person — not the Daphne we follow through the novel. A girl named Daphne Barton did exist in Mabel's kindergarten class and moved to England, never returning. Mabel, facing profound childhood loneliness in a household that offered her nothing, created an imaginary Daphne who stayed with her through adolescence and well into old age. The court's inability to verify Daphne contributed to Mabel's diagnosis of multiple personality disorder and to her being sent to a psychiatric facility rather than prison. The label "mad" was applied precisely when she was most vulnerable and had no one left to speak for her.

The Peter reveal

Peter — the quietly devoted Greek-Australian neighbor who cares for Elsie with no apparent reason — is her biological son. He was born while Elsie was institutionalized, adopted by Ness (her aunt's partner), and raised nearby. He has known her for years. His consistent, undramatic kindness is not random. It's love that couldn't name itself.

Elsie's death

Elsie dies saving Persephone when her father fires a gun. The moment is framed not as tragedy but as a free choice, described in the novel as the easiest decision she ever made. After 60 years of carefully managed survival, she gets to choose.

The final line

Persephone speaks to her imaginary friend "Daisy," who tells her she used to go by a different name: Daphne. The novel ends with the cycle intact. The kind of connection that kept young Mabel alive now keeps Persephone company. It's simultaneously melancholy and deeply reassuring — Hepworth's argument that imagination and love survive even the people who carry them.

📘 Process what you just read, Headway's summaries on trauma and psychology give language to what 'Mad Mabel' renders emotionally.

'Mad Mabel' book club questions

Few thrillers published this year will generate the kind of conversation this one does. The ethics at its center are genuinely unresolved, the reveals reframe everything that came before, and nearly every character turns out to be more complicated than they first appeared. These questions are designed to get into all of it.

1. Mabel is labeled "mad" by her father before she commits any crime. How does the novel show that label shaping her fate — and the community's perception of her — across six decades?

2. Is Daphne's imaginary status a tragedy, a survival mechanism, or both? What does Hepworth seem to be saying about the bonds people create when real connection is unavailable or dangerous?

3. How does the relationship between Elsie and Persephone echo — and diverge from — the relationships young Mabel had with the few adults who protected her?

4. Joan initially appears to be a villain. Does the novel complicate that reading by the end? What does her arc suggest about the consequences of cruelty, even cruelty that comes with a justification?

5. The podcast team arrives wanting to "tell Mabel's story." How does Hepworth use that framing to comment on the media's relationship to survivors and convicted people?

6. Peter has known about his connection to Elsie for years and chosen to care for her quietly, without naming it. What does his decision tell us about what love can look like when it can't be spoken?

7. Mabel committed murder. Does the novel ask us to accept that and still feel sympathy? How did you personally navigate that tension while reading?

8. Elliott is drawn with specific cruelty rather than cartoon villainy. What does Hepworth gain by making him psychologically coherent rather than simply monstrous?

9. Female friendship — between Cess and Ness, between young Mabel and Daphne, between Elsie and Persephone — runs through the whole book. What do these relationships share, and what does Hepworth seem to believe they provide that other bonds cannot?

10. The book ends with Persephone's imaginary friend, Daisy, revealing that she used to be called Daphne. Is that ending hopeful, melancholy, or something else entirely? What did you take from it?

11. The novel skips over much of Mabel's middle life — the decades between the facility and Kenny Lane. Did that gap feel appropriate, or did you want more? What do you think happened in those years?

12. Compare young Mabel to 81-year-old Elsie. What did she preserve? What did she lose? What did she build?

13. The title 'Mad Mabel' uses a phrase that was weaponized against her as a child. By the end of the novel, does that title feel reclaimed, tragic, or ironic to you?

Books like 'Mad Mabel': Fiction that covers similar ground

If the emotional texture of 'Mad Mabel' hit you in a particular way — the unreliable past, the female protagonist carrying a secret for decades, the slow excavation of who someone really is — here are fiction titles that work through the same territory.

'Local Woman Missing' by Mary Kubica is a strong start for readers who responded to the dual-timeline structure and the gap between what a community believes happened and what actually did.

'Then She Was Gone' by Lisa Jewell covers similar ground in its exploration of buried family secrets and the long reach of a traumatic past into a character's present-day life.

'First Lie Wins' by Ashley Elston works well for readers who liked the way 'Mad Mabel' kept its structural reveals close to the chest.

For readers who want a domestic thriller with a morally complicated older protagonist and a slow-burn reveal of what she's been protecting all along, 'The Life We Bury' by Allen Eskens delivers in the same register.

And if the childhood abuse and institutional failure angle stayed with you, 'Small Things Like These' by Claire Keegan takes a different historical and geographic setting but asks the same core question: who is responsible when a community looks away?

What to read next: Top five nonfiction bestsellers that go deeper into the themes

'Mad Mabel' raises questions that psychology and memoir can answer in ways fiction can't. If specific parts of the novel stayed with you, here's where to go next — all available as 15-minute summaries on Headway in both text and audio.

1. 'The Body Keeps the Score' by Bessel Van Der Kolk

If the way Mabel's childhood abuse shaped her body, her nervous system, and her movement through the world stayed with you, Van Der Kolk's research on how trauma is stored and carried offers the science behind what Hepworth renders emotionally. It's one of the most widely cited books on trauma's physical legacy.

2. 'If You Tell' by Gregg Olsen

For readers drawn to the question of what children do to survive an abusive household and how the story gets told, or suppressed, decades later. A true crime account with the same questions about childhood powerlessness and adult reckoning.

3. 'Hidden Valley Road' by Robert Kolker

For readers interested in how institutions — medical, legal, familial — shape the story of a person labeled as "disordered." A deeply researched account of one family's experience with the mental health system that maps directly onto Mabel's institutionalization.

4. 'Know My Name' by Chanel Miller

For readers struck most by Mabel's experience of being publicly defined by a crime before she could speak for herself. Miller's account of reclaiming identity after public judgment resonates directly with the 60 years of silence Elsie carries.

5. 'Toxic Parents' by Susan Forward, Ph.D., and Craig Buck

For readers whose attention was caught most sharply by Elliott, the specific mechanics of parental psychological control, the way it distorts a child's reality, and the long recovery that follows. Forward's framework maps almost exactly onto young Mabel's world.

All five are on Headway. If you're not sure which to start with, 'The Body Keeps the Score' is usually the right answer after a book about childhood trauma.
