Based on a True Story: A Novel

by Sarah Vaughan

A compelling novel about power, money and lies from the author of Anatomy of a Scandal.

All families have secrets. But it's the lies that can kill.

A lavish seventieth birthday party. A body found on a storm-lashed beach. And a secret that someone is dying to tell. . . .

Famed children’s author Dame Eleanor Kingman has summoned her family and friends to her exquisite manor house on the cliffs. They're celebrating her birthday—and her latest number one bestseller in her series of books based on a mother fox and her cubs.

But the night before the party, Eleanor receives an email that threatens to expose the lie she’s kept up for over half a century.

Someone knows her secret. Is it her estranged literary agent? Is it her ex-husband, to whom she no longer speaks? Is it the nanny she fired all those years ago, who always did have a knack for storytelling? Or is it one of her three daughters, all of whom have a stake in the publishing empire she has built...

With a television crew arriving to film a documentary of her life, Eleanor needs to find out who sent the email—and preserve her legacy and multimillion-pound career.

But when push comes to shove, and it's time to tell the truth, will anyone actually believe her?

Reviews

[Dorie - Cats&Books :)]

This audiobook started out a bit slow but that was expected - there are a multitude of characters to be introduced.

Dame Eleanor Kingman has built an empire and a fortune writing extremely popular children’s novels. We join her and her family on the eve of her 70th birthday celebration. Things are going as planned until Eleanor receives a threatening and disturbing email! She’s not sure whether to tell her family or not?? There is a long buried secret that could ruin her if it were found out!

Eleanor reinvented herself after a turbulent childhood. She went to university and started a writing career. She has been very successful through luck, talent and maybe a little help?? Who would want her to fail?? Her ex-husband, past literary agent or illustrator?

The party is to be held at her lavish home on the Cornish coast, sparkling like a gem. But like the sea itself - you never know when things can become turbulent and even deadly!

Eleanor‘s three daughters are gathered together to help with the party. Without going into the plot, I will just say that the sisters have secrets themselves and have done some things that they’re not proud of.

I really enjoyed this audiobook once it got going, and the narration by Juliet Stevenson was excellent. As in so many good books, the atmosphere is a character in itself. The writing was so descriptive that I could picture the party, the sea, the sunset and the wealthy and beautifully dressed party guests.

There are several twists in the novel that are very well done. The ending is clever if perhaps a bit of a stretch.

I can highly recommend this novel which is a great combination of family drama and mystery. Such a unique premise!

I received the audiobook from the publisher and HarperAudioAdult through NetGalley. It was my pleasure to listen to and review this title.

Definitely not thrilling, rather more a cozy mystery. Too many points of view, without much organising to their placement, so I felt thrown around with the sub-plots. Then it felt like not much happened towards the main plot for most of the story, creating a frustratingly slow burn. It had all the tropes to intrigue, but the twists fell flat. Not for me.

[chris pike]

A boring book. No likable or frankly identifiable characters. Self absorbed writers rubbish who's run out of ideas. It's a farcical story. The attempt at tension starts on the first page and the same level of 'tension just repeats itself page after page with the same issues confronting the characters. Even the dog is under threat. Their all under threat .on we go wading through their worried thoughts . Until the final pages. The reveal. Its not even unpredictable and everyone lives happy ever after.

[Sandy Smith]

A slow burn family based urder mystery based around an authors 70th birthday party, Eleanor who is very wealthy. There are lots of points of view, mainly from her three daughters and their relationships. None of the characters are remotely likeable and all have secrets which gradually unravel. Eleanor is being sent threatening emails which threaten to expose her at her birthday party. The plot builds to the climax of the second half of the book. The Cornish setting is a character in its own right providing a moody setting for the plot to play out. Overall a good read if a little slow to begin with.

[Alice]

I really really struggled with how to rate this. This book did not hurt me nor did I ‘hate’ it. However, I have to be honest: I’ve never read a ‘mystery’ book that had so little mystery or suspense and as a huge fan of the genre, I feel quite let down. I’m kind of stunned to be honest. It feels like the author had a deadline to meet, rushed a very basic plot with no twists, reveals or even differing perspectives of characters. It’s all so bland. And yet I finished it, hoping that the author behind the excellent ‘Anatomy of a Scandal’ (although I’ll admit I only watched the tv adaption) would pull something clever in the end. Really disappointed.

[Jane]

It’s Eleanor’s 70 birthday party and she is throwing a lavish party to celebrate this and her literary success. In the run up to the party she has been receiving threatening emails that hint at a secret she has been keeping from her pasts. There’s no shortage of suspects, from her children to her ex husband and by throwing a party Eleanor is hoping to weed the culprit out, but as hinted in the very first chapter things go horribly wrong, will Eleanor survive this party or will this birthday be her last??

It did take a little bit of time to settle into this one but once I got all of the characters straight in my head I really began to enjoy this one. Unlike her previous books I’d described this one less of a thriller and more it’s a family drama that’s brimming with tension, sibling rivalry and secrets. I really rate Sarah Vaughan as a writer, (Anatomy Of A Scandal is one of my all time favourite books) and I hope there’s many more books from her to come.

[Lu thrillskillsandchills]

The cover was what first caught my eye, and this is definitely a book to judge by its cover - thankfully what was inside lived up to it!

Based on a True Story is a character-driven mystery centred around the Kingman family, where decades of buried secrets slowly begin to unravel over the course of a lavish 70th birthday celebration. There are quite a few characters to keep track of early on, but I really enjoyed gradually piecing together how everyone fit into the bigger picture. I was personally just in the mood for something with a little more pace, but I was invested from start to finish and thought the final reveals were well worth the wait.

Tom and Rachel’s storyline was easily my favourite. I do love a gambler storyline, and the pressure created by Tom’s mounting debt had me especially invested whenever the focus shifted to them.

One of my favourite aspects was the underlying question of who really controls the narrative. Eleanor has built a career telling stories, but she may be harbouring a few of her own. Then there’s her children, each with their own agendas and secrets, alongside a documentary crew all trying to tell their version of Eleanor’s life. It made for a really interesting thread running alongside the central mystery.

The Cornish setting added plenty of atmosphere, and the ending pulled everything together in a really satisfying way. A thoroughly enjoyable read!

[MRS C J DENBY]

I was looking to reading this book as I had heard a very good review of it by Andrew Marr on LBC. However, I was so bored, waiting for something to happen. Dame Eleanor, the main character, is so domineering and dislikeable. After reading about two-thirds, I just skipped forward to the end. Cannot recommend it.

[Kagan Goodliff]

I loved anatomy of a scandal and have read reputation more than once. But this one had me checking it was the same author. This was completely different and not in a good way. There was far too much going on and little of it was believable. Ridiculous gambling / loan sharks, patricide, denied siblings, illegitimate children, not one but two cancers, embezzling, affairs, addiction, plagiarism…. Probably more but this list alone is exhausting. I assume the chapter about the illustrator was there to provide a different suspect? But although the identity of the corpse at the start may have been a mystery, nothing else was. The characters were all hideous and, because of the twelve different plots, were cardboard cutouts rather than characters with depth. The worst part is, they all lived happily ever after even though they literally killed someone.

[Trisha]

ooh Pub Date: June 2026. Great author, can't wait to read this!

[Victoria Donelda]

A very boring domestic thriller. I disliked every character, it was slow paced, and there was no wow or shock factor. I would skip it.

[Judy Collins]

A masterfully constructed, slow-burn psychological drama of power, legacy, and toxic family secrets.

In Sarah Vaughan’s razor-sharp thriller Based on a True Story, famed children's author Dame Eleanor Kingman gathers her family at her cliffside manor to celebrate her 70th birthday. But on the eve of the party, a threatening email arrives, promising to unearth a lethal lie she has hidden for over half a century. As a documentary crew rolls and tension peaks, a body is discovered on the storm-lashed beach below—proving that someone in Eleanor's inner circle will kill to ensure the truth stays buried.

The Family Dynamics
The Legend Is Built On Lies.
Three fractured sisters, one toxic legacy, and a body on the beach.

"Vaughan expertly peels back the layers of an affluent family's history, revealing the devastating price of childhood trauma and parental favoritism."

Elevator Pitch
A lavish clifftop birthday party turns into a crime scene when a legendary author's 50-year-old lie is threatened with exposure, forcing her three fractured daughters and bitter ex-associates into a pressure cooker of suspicion.

Intro
Dame Eleanor Kingman built a multi-million-pound publishing empire on her beloved children's books. Yet, her greatest story is the falsehood she has lived for fifty years. When an anonymous blackmailer threatens her legacy right as a television crew arrives to film her life, a dark, multigenerational web of resentment, greed, and sibling rivalry unravels.

Setting
The dramatic, isolated coastal beauty of a magnificent manor house perched on the windswept cliffs of Cornwall, England.

Vibe
Intoxicating, tense, and deeply atmospheric. It carries the elite family-dynasty dread of Succession blended with the classic, claustrophobic mystery of an Agatha Christie whodunit.

Genre
Psychological Drama / Suspense Thriller.

Themes
~The danger of the narratives we tell ourselves to survive
~The heavy burden of childhood trauma
~Parental favoritism
~How the pursuit of public adulation can destroy private lives.

Standout Characters
Eleanor, a fierce, intensely flawed matriarch desperately trying to protect her legacy, and her daughter Delia, the tragic real-life inspiration for her mother's famous fictional child sleuth, who feels perpetually trapped by her mother’s shadow.

Author Writing Standout
Sarah Vaughan (author of Anatomy of a Scandal) is an absolute genius at building simmering, slow-burn tension, expertly weaving intricate timelines together while delivering beautifully evocative descriptions of the Cornish coastline.

Takeaway
All families keep secrets, but it is the stories built entirely on structural lies that eventually collapse and kill.

Title Significance
Based on a True Story plays brilliantly on multiple levels. It highlights Eleanor's career of taking real life and commercializing it into fiction, while pointing to the terrifying reality that the darkest "fiction" in her life is actually the truth.

Metaphor
The storm-lashed beach below the cliffside manor symbolizes the inevitability of the past—no matter how high you build your fortress, the tide will eventually wash up what you tried to bury.

Why You Should Read
A brilliantly sophisticated and character-driven mystery that values deep psychological nuance, complicated sisterly dynamics, and ethical dilemmas just as much as it values a shocking plot twist.

My Thoughts
The pacing is a brilliant, gradual turn of the screw. Watching this deeply dysfunctional family circle each other under the glare of documentary cameras is deliciously addictive. Vaughan peels back the layers of Eleanor's past so deliberately that when the ultimate reveal crashes over you, it hits with the force of a tidal wave.

Verdict: ⭐⭐⭐⭐ (4/5)
A masterclass in domestic suspense that will make you look at family memoirs and biographies in a whole new light.

Recs
Read this if you devoured The Club by Ellery Lloyd, Daisy Darker by Alice Feeney, The Guest List by Lucy Foley, or Sarah Vaughan’s previous masterpiece, Anatomy of a Scandal.

[Jennifer]

This was a fun time murder mystery. I enjoyed digging into all the dirty secrets this family had. I had no idea who, what or why so made it even more fun to unravel it all piece by piece.

You get lots of POV’s but I didn’t find it hard to keep up with them as the chapter tells you whose pov you were getting. I even used audio when busy and had no problem following along. Not really sure why such bad reviews for this one.

I recommend if you like a murder mystery and lots of rich people drama.

[Kelly]

★★★ 1/2
The story centres a children's book author who is gathering her nearest and dearest at her remote Cornish mansion to celebrate her 70th birthday.  There are secrets, blackmail, an unpublished manuscript that could cause some problems and of course, murder.  This is a really slow burn with multiple POV's.  The mystery isn't overly compelling but the writing is wonderful and the ending unexpected.

[Gloria (Ms. G's Bookshelf)]

⭐️4 Stars⭐️
Based on a True Story by Sarah Vaughan is a page turning suspense tale that had me hooked.

When famous children’s author Dame Eleanor Kingman holds a lavish birthday party to celebrate her 70th at her beautiful Cornwall clifftop manor all is not perfect as it seems.

Despicable characters, lies and more lies and then there’s an email that threatens to expose the secret Eleanor’s kept for over fifty years. There is a television crew also attending the birthday party to film a documentary of her life and some unexpected guests arrive.

The story centres around Eleanor and her daughters and is character driven.

A dead body is found on the beach……

The last part of the book really heats up and I couldn’t turn the pages fast enough!

There’s plenty of tension, resentment and a long list of suspects. Eleanor’s dog is a loveable character but most of the humans were questionable. An engrossing dysfunctional family drama with a great atmospheric setting.

Thank you to the wonderful team Simon & Schuster Australia for a copy of the book.

Thank you to NetGalley for the ARC of Based on a True Story by Sarah Vaughan

This was a smart, unsettling and very readable psychological thriller centred on a death at a lavish 70th birthday celebration. What should have been a joyful family gathering becomes something far darker, and Vaughan is excellent at exposing the tensions, secrets and half truths that sit beneath a polished surface.

I enjoyed how the story examines memory, perception and the stories people tell themselves and others to protect their version of events. As perspectives shift, it becomes increasingly unclear who can be trusted and what really happened, which kept me fully engaged. The confined setting and family dynamics add to the claustrophobic tension, making the emotional stakes feel high.

The pacing is steady rather than frenetic, but the psychological depth and gradual unravelling of the truth more than compensate. A clever, character driven thriller that lingers after the final page. A solid four star read.

[Diane OLeary]

Eleanor, a wealthy celebrated childrens book author, is throwing a blow out party for her 70th birthday. 100 guests are invited and a film crew will be at the event filming a documentary on Eleanor's life. Before the party begins Eleanor receives threatening e mails hinting about secrets in her past that could harm her reputation. Eleanor isn't the only one in her family being blackmailed. There are numerous suspects and a trail of secrets and lies involving just about every character. This was a clever and suspenseful story but Anatomy of a Scandal remains my favorite of Sarah Vaughan's works.

[4cats]

I worked out parts but not all. I really disliked all of the characters, which made it not for me. I can see people enjoying it.

[Deborah (debbishdotcom)]

Based on a True Story by Sarah Vaughan is the fourth book I've read by Vaughan, best known for Anatomy of a Scandal which was made into a series on Netflix. This centres around a family gathered for the 70th birthday of a renowned children’s author amid threats to that author–promising to reveal long-buried secrets–and her three adult daughters all grappling with secrets of their own.

We spend time with Eleanor and all three of her daughters but this is preceded by a prologue culminating in the discovery of a body during Eleanor’s 70th birthday celebrations. We then return to the days in the lead-up to the party, as family and guests start to arrive

Vaughan poses some moral or ethical (what-would-you-do?) dilemmas here and there's a lot of 'unpack' in the relationships between the sisters and with their mother, so I think this would be an excellent bookclub read offering much to debate and discuss.

[Karen Cuddy]

Based on a True Story is a compelling and addictive read that I absolutely loved.

The novel centres on Dame Eleanor Kingman, a hugely successful and beloved children’s author, celebrating her 70th birthday at her stunning clifftop mansion. Surrounded by her three daughters — Gilly, Rachel, and Delia (the troubled one) — along with collaborators, publishers, and even a film crew documenting her life story, everything should be perfect.

But beneath the surface, tensions are already building. On the eve of the celebrations, Eleanor has received a series of malicious emails — six in total — clearly from someone intent on damaging her reputation and everything she’s built.

As the story unfolds, it becomes clear that this is far more than just a glamorous celebration. Secrets begin to surface, and Delia isn’t the only one with a troubled past. The novel explores themes of money, greed, loyalty, and the cracks that can form within even the most successful families.

I loved how the tension built throughout, constantly making me question who could be behind it all and why. It’s one of those stories where everyone seems to have something to hide.

A gripping, character-driven read full of intrigue and family drama — highly recommended.

[Rebecca Wiest]

Read this book if you'd like to be bored.

[Olga]

Based on a True Story didn’t quite match the impact of the author’s first book, Anatomy of a Scandal, and left me disappointed.
The pacing was quite slow and at times the plot felt a little forced and repetitive, which made it harder to stay fully engaged. I enjoyed the atmospheric setting but the characters were cliche, their actions didn’t always ring true and many things were over-explained and repeated several times. It wasn’t a bad read, but it didn’t quite live up to what I’d hoped.

[Leah Czlapinski]

Good thing reading subjective and I didn’t listen to the reviews.
I was in need of a good twisty book and this one delivered.
Told from multiple points of view, it was paced absolutely perfectly and the story came full circle in the end. I couldn’t put this book down.
The characters are written in way that you can’t help but want to know more about them. Twists I didn’t see coming. My favorite suspense of 2026

[Sheri Vasconcellos Miller]

A very good book. Filled with family drama,alot of twists. Heartfelt and suspenseful.

[Lata]

Dame Eleanor Kingman is seventy years old, and has had a long and very successful career as a children's book author. She's throwing a milestone party for herself at her cliffside mansion (one of several homes) in Cornwall. Eleanor has invited acquaintances from publishing and others she's known over her career.

Her adult daughters, both of whom work for her, the elder Gilly as publicist, etc., and Rachel as accountant, are in attendance. Gilly has been managing the party planning and her mother's business for years, and is done. She's decided she's quitting after the party, while Rachel is driving from her London with her two children, her husband Tom to follow later. Rachel is beyond furious with Tom, who has gotten himself into serious financial trouble after gambling and borrowing money from a loanshark, who wants his money back RIGHT NOW.

Tom wants Rachel to ask Eleanor for the money (she's got gobs and gobs of it), but Rachel is very reluctant, as she knows her mother is a bit of a miser.

The youngest daughter, Delia, is her mother's favourite, and is a wellness influencer. Delia has had a difficult childhood after her mother used Delia as a model for her series' main character and its publicity. Delia became addicted for years, and has shared her recovery journey online, though, in person, doesn't really buy into all the aphorisms and inspirational sayings she makes about healthy living. Delia is also there for the party, though she's looking to stir up trouble.

Not that trouble is far; Eleanor has been receiving threatening emails, the sender intimating that her successful life is based on a sham, and that there are aspects of her working class life she's excised from the tale she's spun about her beginnings and writing life and success.

There is also a documentary film crew on hand to interview Eleanor, her kids, and select others, to give people a better understanding of Eleanor's long career.

The entire story takes place over a few days as we see everyone in the family spiralling, worried about different things: reputation, money, danger from criminals, and meaning in their life.

At the same time as we learn how successful Eleanor has been, we see a woman who has heavily edited her life, and the story she tells of her influences; there is also talk of her stealing others' ideas without crediting them. In fact, the threatening sender hints at this, and something much darker in Eleanor's youth.

There is much unhappiness and anger throughout, as well as self-justifications, and things get tense till a sudden act brings everyone together. This almost feels too sudden, too easy, with a more or less happy ending ensuing.

The novel was compelling, as we watch a number of pretty entitled characters scheme, act on grudges, make poor decisions and just generally not behave very sympathetically. Except dear little Edith, Eleanor's friendly and energetic spaniel.

[Lois]

This is engrossing but largely a family drama with multiple unlikable characters. There isn’t much of a mystery to this nor much of a thriller element to the story. There are a few reveals but they aren’t particularly revealing.
Still it was better than I described it just not necessarily the genre I was expecting. I think had I been expecting this style of story I’d have given it a higher rating.
This is worthy of reading understanding what it is.
This involved an older author of children’s novels with her daughters who all work for her with their spouses and kids. It’s kind of a look at her life how she relates to her kids, etc. Not a bad family drama just not really much of a mystery or thriller element at all.

[Michaela Summers]

A bit slow, too many storylines, intriguing but not exciting

[Diana]

The pacing was super slow, but building interest and then we got a rushed job at the end.

[Amanda Jane]

There were lots of characters in this one so I found it difficult to work out who was who and what part they played in the book. Unfortunately the characters were unlikeable but the mystery of the story kept me reading on. By the half way mark the story picked up pace and it also had some great imagery of the Cornish settings.

Thank you to the Publisher and the Author for the opportunity to read and review this ebook.

[Thedowns]

Prob a little under 3 stars for me. Just didn't grab me like i hoped
