There are some days that with hindsight we wish we could go back to and spend that day hiding under the bedclothes avoiding what happened and the repercussions of those actions. This is the story in this book, the ripples that come from just one terrible event that reveals a whole lot of secrets that change Jen's life and relationship with everyone around her.
The storyline is gripping and well told to keep those pages turning ever faster in a need to know more secrets and to find out the truths that have been hidden, some well, some not so.
As always it's great to spend more time with Saul Anguish and his unique set of quirks and with that teaser left near the end of his story in this book, I am so eager for the next part of his story and to find out where all that is going!
This was an amazing read as have all the books by this author that I have devoured, this is one talented wordsmith.

Saul Anguish is back — brilliant, tormented, dangerously compelling — and once again at the center of a deeply layered investigation that unearths a long-buried, shocking secret. But Saul’s own secrets are surfacing too, threatening everything, including his freedom. What lengths will sisters go to for — and against — each other? And what will Saul risk to stay out of prison?

Technically, this could be read as a standalone, but I highly recommend reading the earlier books first. It’s not heavily marketed as a series, but believe me, reading in order makes for a richer, more emotionally resonant experience.The relationship between Saul and Blue is the most complicated it's ever been in this book. And that ending — it sent me into orbit. I half-expected it, half-didn’t, and the ambiguity of it? Perfect. It leaves you desperate for the next one.The central mystery around the three Kellaway sisters is gripping and constantly subverting expectations. Just when you think it’s going one way, it takes a sharp, unexpected turn.

You’ve got multiple points of view, timelines layered on timelines, and storylines that seem totally disconnected — until they’re not. Fiona Cummins keeps you in the dark, but never confused (at least not in a frustrating way). And when the pieces finally click into place? It’s mind-blowing. You realize how expertly it’s all been constructed.Yes, these books are violent, dark, and intense — and I love every moment. They’re tense, sinister, and packed with reveals that keep you gasping. If you're new to the series, you can start here but I think you’ll miss a lot of the nuance, especially in understanding Saul’s complexity. For longtime readers, this one’s another knockout.

Highly recommended — with one caveat: You need patience. You need to trust the author. You need to be comfortable not understanding everything until she wants you to. If you like fast, linear thrillers, this might not be for you. But if you enjoy a slow, deliberate burn, masterfully plotted and relentlessly dark — you’ll be hooked, just like me. Now I’m back to waiting… again.

Well Fiona Cummins has done it again-sucked me into an emotional whirlpool that has left me completely wiped out. Some of us are Liars didn’t have the best start for me as it took quite a few pages for me to understand the family dynamics and settle into the rather distressing situation that the characters found themselves in. But once I was able to settle into this highly emotional storyline I became completely immersed and invested in the lives of these three sister whose lives are blown apart after a terrible tragedy befalls them. Be warned that there are some very disturbing moments here that I personally found very hard to read at times but I was in safe hands as the author guided me through them. Sometimes I found the other point of view to be rather disconnected from the main narrative which surprised me as I understood why it was there but I didn’t want it to be-very difficult to describe why but probably because I had become so protective of the people affected by the family secrets take started to unravel during their prospective.
Beautifully written and perfectly executed.

This was a really good interestingly plotted read. It was slightly confusing at first with all the characters going back and forth in time, that I hadn’t a clue what was going on and where everyone was in the story.
The worst possible tragedy happens on the wedding day of Jen and Phil, caused by the reckless actions of Jens younger sister Alyssa. So the plot takes us way back to the girls being children and growing up together and then to before the accident and then present day. Present day where Alyssa is up in court for what she done.

As close as the sisters are there is also betrayal and secrets. I liked the way the biggest secret unravelled, bit by bit. I wasn’t overly fond of any of the sisters, I liked their characters and they had plenty of drama each, but they were each a bit flawed. Jen never stood up to anyone and let others decide things for her. Winter was a self centred, fame hungry women, who railroaded her sisters wedding day into what she wanted and what made her the spotlight. And Alyssa was ok, though as a child she was a whiny, spoilt little madam.

I didn’t enjoy the DC Saul Anguish parts though, what the point of him in this really, he had no real role in the case and the whole Blue relationship is dull and boring. I skimmed over a lot of his parts.

Otherwise, despite the sadness, I really enjoyed it and devoured it happily. Thank you to MacMillan and NetGalley for the ARC in return for an honest review.

Three sisters. One fatality and their close relationship is torn apart. Further betrayals are revealed. Can they overcome the tragedy and rekindle their relationships.
Superb book full of twists and fast paced. I couldn't put it down.

This took me some getting into so I would say a slow burner for me. I know it's part of a series, but it was just a little disappointing with regards to one of the main characters DC Saul Anguish involvement in the storyline. I felt like that was not really integral to the main story and could have even not been in the book. I generally love this author's books but I didn't take to this one as much. That said once it warmed up the storyline between the sisters and some of the themes relating to family loyalty was great reading. And although I was surprised by the twist towards the end the book was lacking this author's usual gripping build up for me.

Another first for me, I have several Fiona Cummins books waiting to read, which will be moving up my TBR pile, after racing through this story. I’m guessing I should have started with an earlier book in the Detective Saul Anguish (what a name!) series, but it worked perfectly as a standalone (yes I will be reading the earlier books!)

Told from a variety of viewpoints and timelines, this plot has everything I look for: intrigue, mystery, suspense, layered plot, surprises and tension.

The characterisation is perfect, bringing flawed, realistic people to life, some unlikeable, some drawing empathy and some creating doubts.

The situation is unthinkable, how can anyone face this tragedy is beyond me! However, the author doesn’t shy away from challenging subjects, rather, she brings them out into the open, providing new perspectives and potential understanding. And this book has a wide variety of issues raised, not just from the main plot either.

I particularly enjoyed the way the plot develops, linking the complicated, unfolding past with present behaviours.

Strength of relationships is also an important aspect of this book, be that sisters, wider family, marital, colleagues or otherwise, which can survive and which in fact should.

The action is well-paced, keeping me engrossed. The plotting is superb, my brain was constantly wondering and trying to work out who had done what. I would thoroughly recommend this if you like dark, twisty stories.

I really enjoyed this dark, emotional, beautifully written gripping thriller. I couldn’t put it down.
A story about family secrets, trauma and deceit, relationships and sister’s bond.
Told through past and present timelines with multiple POV’s building the tension from different angles. The interesting and relatable characters are well written and the twists kept me turning the pages. You just didn’t know who was lying and who was telling the truth.
Definitely recommend if you enjoy family court drama, mystery thrillers. It’s well worth a read. I look forward to reading more from @fionacumminsauthor

Emotional family drama about three sisters and how their secrets, deception and betrayal lead to tragedy. A dark and twisty tale of domestic suspense.

Told from multiple viewpoints, this is a family saga. When Jen and Phils child Teddy has a tragic accident when he falls overboard on a boat, family tensions begin. Jen's sisters, Alyssa and Winter hide secrets and all is about to be revealed. Alongside this is the detective Saul and his relationship with Blue. I feel that his story must have started in a previous book as there were many gaps in his back story..
Usually I love these type of stories but this one jumped about too much and I found it hard to keep track of who was who and the timeline.

I wasn't sure about this book by the time I'd finished - it felt like two disconnected stories stitched together for no apparent reason.

On one hand we have three sisters who live lovely lives; one a supermodel, one a mother of two and one dillying about and soon to be a mother. Then tragedy steams into their lives and wrecks all they knew.

On the other hand we have a rather odd detective, Saul Anguish, who collects momentoes of murders he has attended and is clearly very, very strange.

The story around the three sisters was quite good, although I predicted several of the twists before they arrived. There was a back story that eventually gets linked in, tying it all up neatly. I never really saw the point of Saul and Blue's involvement, it just irritated me really. The characters are well defined and the story is well paced.

I've read and loved all of Fiona Cummins' novels to date but I think Some of Us Are Liars might be my new favourite! This book follows a family of three sisters and what happens when one of them is responsible for the death of the child of one of her siblings. I love the way this was told through multiple viewpoints and that we get a perspective from the past too. I could see where some of this book was going but that didn't spoil the enjoyment of reading because I was so invested in how it was going to be revealed to the other people in the story, and what the fallout was going to be. Even then there were things that I hadn't seen coming so I loved that it still surprised me when I thought I had it all figured out. This was such a good read and I can't recommend it highly enough!

Wow! Packed with twists, I wasn’t sure what was going on for a while. Excellent story with great characters! I really enjoyed this and once I’d started I couldn’t put it down.

Three sisters - a tragic accident - another superb twist at the end !
Brilliant - couldn’t put it down !!

Thankyou NetGalley for an ARC in return for an honest review

So there is not a page of this book that isn’t brilliant to read, wall to wall psychological thriller with excellent pacing and you will feel the suspense heavy on you the entire time.

There is so much to love here, difficult family relationships, tragedy, emotions and all the strong feelings that come with it.

I can’t think of anyone who enjoys thrillers that wouldn’t enjoy this novel, as it has everything. It would be a great present too.

Fiona Cummins’ Some of Us Are Liars is a masterclass in psychological suspense—an emotionally charged, intricately plotted family drama that crackles with betrayal, grief, and the kind of devastating secrets that can destroy lives. Blending the domestic intensity of Lisa Jewell with the ethical complexity of Jodi Picoult, Cummins crafts a narrative that’s as compulsively readable as it is emotionally haunting.

The story begins with a celebration—a wedding at a glittering seaside estate hosted by Winter Kellaway, the glamorous, enigmatic sister of Jen Miller. But the champagne barely has time to fizz before tragedy strikes, and Jen’s young son ends up at the center of an unthinkable event. What follows is a slow, deliberate unraveling of the truth, told through shifting perspectives, fractured timelines, and the dangerous space between memory and fact.

The emotional core of the novel lies in Jen’s heartbreak. As a mother, her devastation is raw and deeply felt, made even more excruciating by the fact that those responsible might be her own sisters. Cummins brilliantly captures the nuances of sibling love and rivalry—how loyalty, jealousy, and long-held resentment can quietly fester beneath picture-perfect family moments. Each woman in the story is fully fleshed out, and the narrative doesn’t offer easy villains or heroes—just real, complicated people who made choices they now can’t undo.

Enter Saul Anguish, the detective assigned to the case. Brilliant, intuitive, and haunted by his own demons, Saul is a compelling figure whose investigation acts as both a procedural spine and a philosophical inquiry into guilt, justice, and forgiveness. His involvement gives the story a sharp edge and ensures that Some of Us Are Liars isn’t just a tale of family implosion—it’s also a gripping mystery.

What sets this novel apart is Cummins’ gift for structure and pacing. She doles out revelations with surgical precision, layering past and present until the emotional and narrative climax hits like a gut punch. It’s not just about what happened at the wedding—it’s about everything that came before, and how one family’s legacy of silence and avoidance became its undoing.

Minor caveat: The complexity of timelines and POV shifts may demand a bit more attention from the reader, especially in early chapters. But it’s worth the effort—every thread eventually ties back into the devastating whole.

Perfect for fans of:
• Lisa Jewell’s The Family Upstairs
• Jodi Picoult’s morally tangled dramas
• Domestic thrillers with psychological depth and character-driven suspense

Final thoughts:
Some of Us Are Liars is a gripping exploration of how love and betrayal often coexist in the same breath. With a cast of flawed, believable characters and a secret that changes everything, Fiona Cummins reminds us that the truth can be the most dangerous thing of all. A chilling, emotional, and unforgettable read.

Some of us are liars is a crime fiction book that delves into the family drama of the Kellaway sisters.

A tragic death in the family threatens to pull this once close family apart and spill the secrets that all three sisters are hiding.

Saul Anguish is the detective on the case and he has his own issues, becoming more elusive and creepy with each book in the series which also makes him more intriguing.

Past and present are weaved together cleverly to tell the story and I loved the twist.

Really enjoyed this one and can’t wait to see what direction Fiona Cummins takes Saul in in the next book.

Generally the pacing was good and I was very invested in the story. Whilst the twist didn't quite hit me the way I'd hoped, overall I enjoyed this book

A new book from Fiona Cummins, this means settle in your comfy reading chair and be prepared not to move as you will be hooked from page one.
This is a gripping, rather dark, psychological thriller, a clever story woven together, where the truth is never simply the truth.
Three sisters, individuals and very different, their story is filed with secrets. Jen leaves her youngest child with her two sisters, Alyssa and Winter, in a blink a devastating tragedy occurs, which leads to a huge rift between them. A familiar character, Detective Saul Anguish is investigating. A tense court case, buried family secrets, everyone has something to hide.
Great characters, an intense emotional read with lots of very clever twists and a jaw dropping ending!
This is five star read and a top read for 2025.

I’m new to Fiona Cummins and found ‘Some of us are Liars’ a very compelling read. Ms Cummins has a real super power in drawing complex, believable and somewhat flawed characters. My absolute favourite kind.

Although in the book description this is hailed as a thriller, I wouldn’t really term it that - but it is a dark family drama oozing secrets, betrayal and missteps. Tightly written with a strong plot and well fleshed out characters.

Tragedy strikes at a family wedding and Saul Anguish is called in to investigate (Saul deserves a whole review just to himself, loved him to bits - is he a good guy, or a bad guy? Is he a bit quirky or sinister and very creepy? I still don’t know and I’ve just read the book!). Is there a case to answer here or is it the most awful of accidents?

Thanks to Netgalley for providing an advanced copy in exchange for an honest review. Highly recommended.
