[Mandy White (mandylovestoread) · Rating 5 out of 5]

I am always exited for a new Eddie Flynn book, can you believe this is book 10! I love a good legal thriller and Eddie is one of my favourites. Former conman turned lawyer, Eddie has away of looking at the evidence in a different context to most, and he is not afraid to say what he really thinks, landing him in trouble most of the time. That is kind of lawyers you want on your side.

Highly addictive and very easy to binge read, One of Us is Guilty is one of his toughest and dangerous cases. He is up against the might of the powerful Vanderpool family who are ridiculously rich and own most of the media companies in New York. They are willing to do anything to protect their own.

I love Eddie and his trusted team of Harry, Bloch, Lake and of course Denise. They are all fiercely loyal to Eddie and will do whatever it takes to get the answers. There is always tension around these huge cases and it makes for an amazing read. The courtroom scenes are always my favourites, and more so in this book where everyone is against him and his client.

Another incredible read from Steve Cavanagh. Thank you so much to Headline for allowing me to read this book early. Out on July 30th.

When this proof popped through my letterbox last Friday, I just couldn’t believe my luck! This is my favourite thriller series, so I just couldn’t resist diving into this latest one straight away.

And what a rollercoaster of a ride it was: it was absolutely BRILLIANT! Eddie Flynn fans, you’re in for a real treat with this one.

Once more, Steve Cavanagh stuns and surprises with his cleverly written plot, which is intricately woven together like a spider’s web. I loved the different POVs, the different scenarios, and the wit and humour woven throughout.

I just love it when Eddie stands up to begin a trial in court: I get a tingle of excitement with the anticipation of seeing how he’s going to handle each case, and I adore seeing how he outwits his adversaries, and takes them down a peg or two.

Theres a lot more to this story than the courtroom though, and I loved seeing Bloch and Lake play a part in the action again. I was on tenterhooks the whole way through: wondering what was going to happen next, and who the guilty person was. For once, I did wonder if Eddie had backed the right person.

This is the tenth book in this series, and I just relished every page and chapter. It’s an action-packed, masterfully crafted read, and it’s my new favourite book in the series! 🙌🙌


I was sent a proof by the publishers in exchange for an honest review. All opinions are my own.

Thank you to NetGalley and Atria Books for providing me with an eBook copy in exchange for an honest review.

Wow! Where do I even begin with this fast-paced crime thriller?

The story opens with a gruesome murder, and at the center of it all is a wealthy, powerful couple. Molly, the victim, was an assistant on Patrick’s political campaign, and also his mistress. Vanessa, Patrick’s wife, knew about the affair and understood that her life would be forever changed if it continued. So when Molly ends up murdered, everyone becomes a suspect. Was it the charming, up-and-coming governor trying to save his career? Or the scorned wife pushed to her breaking point?

I had no idea this was book 10 in the series when I requested it on NetGalley, but I was able to jump right in without feeling lost. The author does an excellent job of making the story accessible for new readers while still making me want to go back and read the earlier books.

From beginning to end, this book had my anxiety through the roof. I actually had to take several breaks between chapters just to calm my heart rate! It was a wild, twist-filled ride that kept me guessing until the very end. I’d happily have Eddie Flynn as my lawyer anytime. I loved this book so much that I can’t wait to go back and read the rest of the series!

Another great Eddie Flynn novel! One of Us is Guilty actually made me squeamish and that never happens. I love seeing what kind of antics Flynn and his team get up to. Such great characters and I love how well they work together. This was a great installment.

Thank you so much to Netgalley for giving me this free advance copy, and I’m writing this review honestly and without bias.
I could quite easily sum up this review with one line
Cavanagh + Flynn = 5 stars
Yes, yes, yes! Steve Cavanagh has whacked his latest Eddie Flynn book way out of the park. This is a very clever put together plot that moves at a relentless pace and had me on the edge of my seat for the entire book. The courtroom scenes are so brilliantly done and Eddie proves why he is one of my most favourite characters in a book. There are twists and turns that will leave you gasping and oh my that ending - did not see that coming. Sheer brilliance. Steve Cavanagh is the absolute master of a courtroom drama and ten books in he is still very firmly at the top of his game. I have given every book in this series five stars and this one is no different. Outstanding

Thank you to NetGalley and the publisher for an arc of this book. All opinions are my own!

Holy crap, I love this Eddie Flynn series so much. It genuinely just keeps getting better and better, and I honestly don't know how Steve Cavanagh still has ideas left because every book somehow manages to top the last one.

One of Us Is Guilty follows Patrick and Vanessa Vanderpool, a powerful couple whose lives are turned upside down when Patrick's mistress is found brutally murdered. With only two suspects and secrets everywhere, Eddie Flynn is pulled into another dangerous case where nothing is as straightforward as it seems.

This book had me punching my bed multiple times because I kept thinking, "Are you serious right now? That did not just happen." The twists were absolutely insane and delivered everything I want from a legal thriller. I was completely locked in from beginning to end. Cavanagh's knowledge of the legal world always shines through, and it makes these books feel so authentic.

I also loved how the story bounced between different characters and POVs without ever becoming confusing. Everything came together perfectly, and every perspective added something important to the bigger picture.

One thing I really appreciate about this series is that these books can absolutely be read as standalones, and you'd have no problem jumping in here. But following Eddie Flynn throughout the series and watching him grow has been amazing. He's not only a complete badass, but he's also incredibly smart, witty, and exactly the kind of lawyer you'd want on your side, even if he tends to do things the Eddie Flynn way.

Another phenomenal installment and easily one of my favorite legal thriller series ever. Read this immediately. You will not regret it.

[Lu thrillskillsandchills · Rating 5 out of 5]

Although I have all nine previous Eddie Flynn books sitting on my shelf, I somehow started the series with an advanced copy of One of Us Is Guilty instead… go figure!

If there’s ever been a sign to finally get my shit together and properly work my way through this series, this book was the sign that smacked some sense into me because I absolutely loved this.

The courtroom scenes were phenomenal, the writing had me completely immersed, and I could visualise everything so clearly it genuinely felt like a movie playing out inside my head while I was reading. Those short chapters combined with the pacing made this ridiculously addictive and I flew through it.

Throw in rich people superiority complexes, multiple POVs, corruption, layered reveals, courtroom drama and an ending I absolutely did not see coming, and this became exactly my kind of thriller.

This book was basically catnip for me. Safe to say I’ll now be heading back to finally start the Eddie Flynn series from the beginning because if One of Us Is Guilty was this good, I need to know what I’ve apparently been missing out on all this time.

Steve Cavanagh is one of my favorite authors and I eagerly await each of his releases, so when I got a bookseller proof copy I had to read it immediately.
I knew Eddie Flynn 10 was going to be a big one and it absolutely did NOT disappoint!!

One of Us Is Guilty puts a wealthy, high-profile couple at the center of a gripping murder investigation. Eddie Flynn, as always, finds himself risking everything to uncover the truth and the stakes have truly never been higher.
The book is packed with clever details and hidden clues, and I didn't see a single twist coming. ESPECIALLY that final chapter. Steve. You are brilliant.

I genuinely can't wait to get this into the hands of everyone and share this brilliant book with them!

⭐⭐⭐⭐ 4/5

Thank you to NetGalley and the publisher for providing me with an advance copy in exchange for an honest review.

One of Us Is Guilty by Steve Cavanagh is a fast-paced legal thriller that pulled me in from the very first chapter. The story kicks off with a shocking murder tied to a wealthy, powerful political couple, and from there the twists just keep coming. Everyone has something to hide, and I was constantly changing my mind about who I thought was guilty.

I had no idea this was book 10 in the Eddie Flynn series when I requested it, but that honestly didn’t matter. It works incredibly well as a standalone, and I never felt lost. Steve Cavanagh does a great job of giving new readers everything they need while still making longtime fans feel rewarded. If anything, it made me want to go back and read the earlier books.

This was one of those thrillers that kept my anxiety through the roof in the best way. Every time I thought I had everything figured out, another twist proved me wrong. Eddie Flynn was such a compelling character, and I can definitely see why so many readers love this series.

If you’re looking for a smart, addictive legal thriller with nonstop suspense and plenty of surprises, I’d definitely recommend picking this one up. I’ll absolutely be going back to read the rest of the series.

[Susan W · Rating 5 out of 5]

Well... Steve Cavanagh got me again. At this point, Eddie Flynn could cross-examine me into confessing to things I didn't do. By the end, I felt like I'd earned jury duty credit.

This psychological legal thriller follows a wealthy, high-profile couple whose marriage is imploding, and both have compelling reasons to want the mistress dead. Turns out "till death do us part" wasn't just a wedding vow.

Never bet against Eddie Flynn—especially in a courtroom. He's hands-down one of my favorite fictional characters. There's something irresistible about a defense attorney who's always three steps ahead, can spot a lie before it's spoken, and treats the courtroom like his own chessboard. My favorite scenes were the courtroom showdowns. His bold, fearless tactics—especially his exchanges with the judge—never got old.

And can we talk about Bloch? She's every bit as smart, fearless, and capable as Eddie, and I loved every scene she was in. Together, they're such a fun team to root for.

Needless to say, I was fooled, entertained, and reminded why this series keeps climbing my favorites list. If you love legal thrillers—or Eddie Flynn in particular—this one is a must-read.

Thank you to NetGalley and Atria Books for the ARC in exchange for an honest review.

At every stage you think you have the murderer figured out, and Eddie Flynn is having the wool pulled over his eyes. But of course he’s not, and he has more tricks up his sleeve than any prosecution in his way. Everything we have come to expect from a Steve Cavanagh book is in here, cunning, wit and brilliant story telling. Thank you to Netgalley for the advance reader copy.

4.5 ⭐️

Eddie Flynn is back in book 10 of the series, and releases in the uk ok 30 July 2026, I was lucky enough to receive an arc copy from NetGalley.

In one of us is guilty we meet Vanessa and Patrick Vanderpool, extremely rich, ambitious and powerful.
Patrick is having an affair with his staff member Molly, Vanessa has found out and the affair could ruin absolutely everything.
Molly is brutally murdered and one of them is guilty, but who?
It’s Eddie’s job to find out but risks his life in the process.
Not everyone is who they seem, hidden secrets need to be revealed.

I couldn’t put the book down, Steve has the ability to keep you hooked at the end of each chapter and before you know it your half way through the book.

I enjoyed the return of a few old characters who we haven’t heard from in a while, one especially from the start who’s one of my favourites just a shame there wasn’t a few more chapters of him, and of course the return of the usual people who make up Eddie’s unlikely but trustworthy team even with their unconventional ways of getting to the truth.

There are also some very unlikable characters too who I was silently rooting for their demise, did they get it and was justice served, well you’re just going to have to read the book to find out.

The master of a twist in the tale and as always hits you with a few curveballs towards the end, I guessed a few but some I didn’t.

You can read these all as stand alone books or in any order, my brain won’t allow that as I enjoy the character development so I’ve read the series in order and enjoyed every single one of them and roll on the release of book 11.

Thank you Net Galley for this early copy.

i love the kind of thrillers where you think you know something, but then you actually don’t, and the more we read the more we discover new things, and it keeps us on edge until the end. It’s exactly what this is and I devoured it literally.

Only when I did finish this, that I realize this was part of a big serie, and is the 10th book of it hahaha…but honeslty this wasn’t bothering or anything, and I didn’t feel lost while reading so if you don’t want to read the whole serie, you still can read this one!!
Though, after this one, I’m definitely gonna read all the others book because oh!my!god how I enjoyed this one.

I loved that there was a lot of twists, unexpected ones, and kept me on the edge until the very much end. One thing that I absolutely loved was the writing that was so good, and had you immersed in the story so well, and the more you read and the more you wanted to know, and the pacing was excellent !!

*Thank you to NetGalley and the publisher for an ARC of this book in exchange for an honest review!*

4.5 stars rounded up to 5 stars.

Another great installment of the Eddie Flynn series! As can be expected with any Steve Cavanagh novel, One of Us Is Guilty was a complicated case with many moving parts. You think you have an idea of what is going on while also questioning how in the hell Eddie will be able to pull out an acquittal for his client. The case looks hopeless as the trial begins and you just hope all of your favorite characters make it out alive. When the final twists were revealed, I was gasping aloud and blindsided. As it should be with a true twist, all the clues were there but I did not connect the pieces until Cavanagh revealed them to me. I love that all the moving pieces and questions are accounted for and everything ties together in the end with your jaw left hanging on the floor. Love it and the entire Eddie Flynn series. The ONLY reason I am not giving this book 5 stars is because I felt there were times when Eddie was not 100% on his game and picking up on when he might have been being lied to or conned. Usually Eddie immediately spots it but there were times in which I thought he might be losing some of his edge. Otherwise, this would be an east 5 star read!

[Candance Nolen · Rating 5 out of 5]

There simply aren’t enough stars to rate this book! If I could give it 10 stars, I absolutely would.

Steve Cavanagh has done it again. One of Us Is Guilty is a masterfully crafted legal thriller packed with jaw-dropping twists, relentless suspense, and impeccable pacing. From the very first chapter, I was completely hooked and found myself saying “just one more chapter” until I reached the end. Every time I thought I had the mystery figured out, another twist proved me wrong.

Eddie Flynn continues to be one of my all-time favorite thriller protagonists. He’s sharp, fearless, and endlessly compelling, and watching him work alongside the rest of the gang was an absolute treat. Their chemistry and cleverness make this series stand out from so many other legal thrillers.

This is the kind of book that keeps you on the edge of your seat from beginning to end, and I genuinely couldn’t put it down. If you’re a fan of twisty, fast-paced thrillers with unforgettable characters, this one is an absolute must-read.

4.5 ⭐️⭐️⭐️⭐️

This is only my 3rd book by this author and I really enjoyed another great read full of drama and unexpected twists!

One of us is Guilty is a fast paced thriller about a woman who is accused of murdering her husband’s mistress. Defense attorney, Eddie Flynn takes on what appears to be an impossible case full of lies. As the investigation unfolds, corruption, political power, family secrets, and deception all come together for a page turning legal thriller.

The very first page gripped my attention to want to know how the story ended! I loved all the clues throughout that all tied together at the end with a twist I didn’t see coming! The first few chapters did feel a little slower than I typically enjoy, but the chapters were short and once the courtroom drama started, it was hard to put down.

Definitely recommend if you like the courtroom drama with clues throughout to determine who is guilty!

[Helen Leecy · Rating 4 out of 5]

Steve Cavanagh really knows how to pull me straight back into Eddie Flynn’s world, and One of Us Is Guilty felt very much like him on form again. This had everything I enjoy about this series, the courtroom drama, the danger, the twists, and that brilliant cunningness that comes from Eddie being a con man as much as he is a lawyer. There is always something so satisfying about watching him work, because you know he is looking at things from an angle nobody else has quite considered, and I love that about him.
I was really pleased to see Bloch play a bigger part in this one too. She has always been a character I have liked, but here it felt as though she had more space to step forward and actually be in the thick of it. I enjoyed seeing her in action more, rather than just hovering around the edges of Eddie’s story, because she brings a different energy and strength to the book. Eddie is still very much Eddie, of course, but Bloch gave this one an extra layer for me.
The tension is there throughout the whole book, and Cavanagh does a brilliant job of keeping you unsure. I genuinely didn’t know what had happened, or whether the defendant was guilty or not, and that uncertainty kept me turning the pages. It is one of those books where you feel as though you are being given pieces of the truth, but never quite enough to put the full picture together. I liked that feeling of being kept on edge, and there were plenty of moments where I thought I had worked something out, only for the story to move in another direction.
That said, I didn’t really take to Vanessa. I wanted to feel more for her, especially given her situation, but I found myself getting frustrated with how little she fought her own corner. I know not every character can react in the way you want them to, and people under pressure do not always behave logically, but it annoyed me that she often seemed unwilling, or unable, to properly speak up for herself. I found her quite hard to connect with because of that, and it did make some sections less gripping for me than they might have been.
My biggest issue, though, was that I did feel a little lied to in places. I do not mind being misdirected in a thriller, in fact, I usually love it when it is done well, but there were a few inner monologues and thoughts that later turned out not to be true, and that grated on me. It felt as though some things had been included purely for shock factor, rather than because they naturally fit with what the characters knew or believed at the time. There is a difference between a clever twist and making the reader feel as though the rules have shifted after the fact, and this did slightly fall into that for me.
The ending also left a bit of a bitter taste in my mouth. I had to reread it a few times because at first I thought I must have misunderstood something or that it was a mistake. Once I realised it was deliberate, and not something that had been overlooked or under-researched, I found it quite hard to come to terms with. The way the facts were essentially undone by a donation did not sit right with me. I can understand the point being made, and I can see why it was written that way, but it still left me feeling a little unsettled, and not entirely in the way I wanted.
Even with those flaws, though, I thoroughly enjoyed the book as a whole. It was fast, tense, and clever, and it reminded me why I enjoy this series so much. Eddie Flynn books always have that extra spark to them, because they are not just legal thrillers, they have danger, heart, manipulation, and the kind of sharp plotting that keeps you reading far later than you meant to. This one was not perfect for me, and there were definitely a few things that frustrated me, but it was still a really strong read and another reminder that Steve Cavanagh knows exactly how to keep a reader hooked.

When I get an opportunity to read the latest Steve Cavanagh book-It goes straight to the top of my ARC pile-regardless of publication date! So here we are!

“The worst times of your life seem to last an age”

And, the book opens with Eddie Flynn having one of those moments-as he wakes up in the trunk of a moving car, wondering if when his abductors pull him out, he will be taking his last walk….

But, of course, we will have to circle back to that.

How did he end up in this predicament? It started FIVE MONTHS earlier with a MURDER….

Patrick Vanderpool, son of a billionaire media mogul, is running for Political Office but the affair he's having could derail everything.

Vanessa Vanderpool, is his wife, and she is not about to turn a blind eye to this affair. She has warned the young lady in question-Molly Green-to stay away from Patrick but she doesn’t appear to be listening.

She arrives at Molly’s apartment and waits until she sees her husband leave.

When the “OTHER WOMAN” is found brutally murdered, there are only two suspects.

Patrick and Vanessa

Was Molly dead when Vanessa arrived or was Vanessa the one who killed her?

ONE OF THEM IS GUILTY

The story unfolds through various viewpoints but mostly through those of Patrick, Vanessa and our FAVORITE Conman turned defense lawyer the VERY VERY CLEVER Eddie Flynn. Because both suspects are sharing their version of the truth, there is some repetition in the chapters, as parts of their story are identical-but parts are drastically different.

We find out how events led to this outcome beginning SIX weeks prior to the MURDER and then learn more about halfway through the book when the TRIAL begins-circling back to the trunk of the car BEFORE there is a verdict.

Since Eddie’s partner Kate left the law firm in the last book, it’s Eddie and Harry at the Defense table, and nothing could make me happier as Eddie will take RISKS at Trial which the straight laced Kate wouldn’t, making for a much more ENTERTAINING experience in the Courtroom.

Bloch (FEARLESS!) and Gabriel Lake are still investigating and Denise is still running the office so we get to catch up with them and others from earlier books. Although this can be read as a standalone, the relationships between the characters grow and evolve throughout the series, so it is beneficial to read them in order to appreciate that.

I was correct with many of my guesses, but there was a twist in the end that I didn’t suspect making this another COMPELLING read and nearly impossible to put down!

Will we get an Eddie Flynn book 11? I have no idea but I would be all for it, and that SPEAKS VOLUMES because as a general rule-I don’t like many series-but I can’t seem to get enough of this one!

Warning ⚠️ The Murders in this installment are pretty graphic!

A buddy read with my lovely friend Ceecee from the UK! I was delighted that we could read this one together and share our thoughts along the way! Be sure to watch for her review!

Expected publication date in the UK: July 30, 2026

Thank You to Headline Publishing and Steve Cavanagh for the gifted ARC provided through NetGalleyUK. As always, these are my candid thoughts!

Eddie Flynn #10
Eddie is back to three resounding cheers.
Currently, Eddie is in the boot of a car, he knows the end could be near and as per usual, his ability to get himself into trouble is some kind of gift. How does he get there? This story starts five months previously with the brutal murder of Molly Green, assistant to Patrick Vanderpool, the son of billionaire Julian Vanderpool. Patrick has political ambitions and this could well jeopardise his chances of success especially as he has been having an affair with Molly. It’s obvious he will be a murder suspect alongside his wife Vanessa. One of them is guilty but which one? Eddie and his team need to learn the truth but they put themselves at great risk.

Steve Cavanagh is back with a bang. Right from the start, he has me scratching my head trying to figure it all out. First of all, why is Eddie brought into the defence team? These people are über rich and could have anyone and yet they pick our Eddie. Do they want a fall guy for some reason? If so, they don’t know Eddie. Secondly, some characters are really hard to read, even Eddie is perplexed and if he’s perplexed, I’m doubly so. At least one of them is up to something, that’s clear from the start, but what? We have to wait a while to find out and it’s clever.

There are several points of view (about five) but with this author it’s part of the plot ruse and there are two conflicting points of view which add to the conundrum of who is telling the truth. There are so many layers to it that it’s hard to discern and I love that air of uncertainty. There is some repetition and overlap and whilst I can see what the author is trying to do here, at times it’s almost word for word.

The courtroom scenes are, as usual, really good. There aren’t perhaps as many Eddie tricks but I love how he is prepared to challenge and keep challenging despite the odds that are stacked against him. I love the hits too about the law and those with money, power and thinking the rules are not applicable to them– more disruptors like Eddie are required! One character in particular has me apoplectic with anger at what he believes he can get away with. He is 100% odious.

The plot twist and turns, I like the pace it’s told at which perfectly suits the storyline. It’s scary in places with danger levels at Mach 1, it’s exciting, tense and suspenseful. I thoroughly enjoy some occasional bits of humour especially from one very colourful character with an equally colourful nickname. I like the ending, it’s good, I have worked part out but not all and everything slots neatly into place. However, after all the excellent buildup, it could maybe have had more oomph.

Overall though, it’s another cracker of a read, so buckle up as this one gets very bumpy.

With thanks to NetGalley and especially to Headline for the much appreciated in return for an honest review.

This was a great buddy read with my lovely friend Jayme - be sure to check out her review!

[Gary · Rating 4 out of 5]

One of Us Is Guilty, is the tenth novel in the Eddie Flynn series by Steve Cavanagh. Conman turned defence lawyer Eddie Flynn must risk his life to find out. Eddie Flynn is a New York lawyer, having made the switch from a co artist and believes the two roles aren’t that different.

The story centres on New York’s absolute elite, the Vanderpools, a couple who seem to have it all, but are secretly built on a foundation of lies. Patrick Vanderpool, the son of a billionaire media mogul, is a man destined for immense political and societal power. But he has a weakness: an illicit affair that threatens to bring his entire future crashing down. Vanessa Vanderpool, married to one of America’s most influential men, is driven by her own fierce ambitions. Yet, she is trapped in the exact same toxic dynamic, knowing an affair could ruin everything she’s worked for.

When the “other woman” is discovered brutally murdered, the police are left with only two suspects. One of them is a cold-blooded killer. But which one? To solve an impossible case where two powerful people are pointing the finger at each other, you need a defence attorney who can see right through a performance. Enter Eddie Flynn.

Eddie isn’t your typical Ivy League lawyer. He’s a former New York con artist who traded a life of street hustles for a legal gown. In Eddie’s world, cross-examining a witness on the stand isn’t all that different from playing a mark on the street, both require reading a room, anticipating a lie, and manipulating human nature to your advantage.

But defending one half of a billionaire power couple isn’t just a legal challenge; it’s a death warrant. As Eddie steps into the crosshairs to uncover which Vanderpool is telling the truth, he quickly realises that powerful people will stop at nothing to keep their secrets buried, putting his own life squarely on the line.

This is an excellent addition to the Eddie Flynn series, One of Us Is Guilty proves how good Steve Cavanagh is. By only have two suspects, a husband and wife, the narrative creates a tense setting where every piece of evidence can be interpreted two different ways.

Eddie Flynn remains one of the most uniquely entertaining protagonists in crime fiction. Watching him use his street-smart grifter instincts to outmanoeuvre high-priced corporate attorneys and corrupt elite systems is an entertaining change from other legal thrillers. The novel is well paced with an intriguing plot.

I would like to thank both Netgalley and Headline for supplying a copy of this novel in exchange for an honest review.

Final Thoughts: ​I enjoy learning legalese through fiction. I was unaware of how deep the Marital Confidences Privilege goes in New York compared to other states; when the author was explaining the law, I had to do a deep dive to discover if it was true. There was a previous book where they bent the law for the sake of fiction and I assumed this would be the same, but it was not.
​One of Us Is Guilty didn't quite deliver the same explosive "bomb" of intensity as the previous Eddie Flynn books I’ve read (I’m still waiting on #3 and #7 to be published in the US), but it was still a five-star read all the way through. It is nice to dive into a mystery where I genuinely couldn't figure everything out. I’ll likely be reading this again next year, as I’m sure one of my book clubs will snap it up as a selection.
​For those curious about the series: The first part definitely needs to be read in order, but the latter part is written in a standalone format where you can jump in anywhere and only get vague spoilers for the previous books instead of a direct continuation.

​Recommend to others: Yes! With the way this man weaves a web for a novel, this series could probably go on for 50 books, and they would all be good.

Patrick Vanderpool is the heir to a media empire. His wife, Vanessa, is determined to protect her family's power at any cost. When Patrick's mistress, Molly Green, is found brutally murdered, both become prime suspects in a case where lies are currency and the truth is buried beneath layers of wealth, influence, and manipulation. Enter Eddie Flynn, the former conman turned defense attorney who has built a career on spotting what everyone else misses. As he digs deeper into Molly's death, it becomes clear that someone is playing a very dangerous game, and Eddie may be the next target.

At this point, Eddie Flynn has earned his place among the most beloved characters in thriller fiction, and somehow Steve Cavanagh keeps finding new ways to make him shine. Every time I finish one of these books, I tell myself there is no way the next installment can possibly top it. Every time, I am wrong. The plotting here is so sharp and so deceptively clever that I spent the entire book trying to get one step ahead, only to discover Cavanagh was ten moves ahead of me. The twists don't feel manufactured; they feel authentic, unfolding with the kind of precision that makes you immediately want to start the book over and see what clues you missed the first time.

What I love most about this series is that it never settles for simply being a legal thriller. These books are puzzles, character studies, and adrenaline-fueled page-turners all at once. The tension is relentless, the reveals are jaw-dropping, and Eddie remains the perfect guide through the chaos because he is every bit as clever as the reader hopes he will be. 𝐎𝐍𝐄 𝐎𝐅 𝐔𝐒 𝐈𝐒 𝐆𝐔𝐈𝐋𝐓𝐘 is another absolute knockout from Steve Cavanagh and proof that this series isn't just maintaining its quality, it's somehow getting better with every single book. Many thanks to Headline for the early copy that publishes in the UK July 30, 2026.

I absolutely LOVE this series and, if you haven't already read it, I would definitely recommend you start at the beginning and read in order. Eddie Flynn is the BEST character and you really do need to meet and get to know him properly to fully appreciate his awesomeness.
We start with Eddie waking up in the trunk of a car. Quite how he got there is one heck of a story...
Patrick Vanderpool is the son of a media mogul who is about to stand for office. He is also one of the two initial suspects to the brutal murder of Molly Green, his PA and mistress. The other suspect and indeed defendant after her arrest, is his wife Vanessa and it is her that Eddie is tasked with defending.
I'm not saying any more about anything as, if you have read this series before, and you have, you'll know exactly what you are letting yourself in for.
Suffice to say all the shenanigans that Eddie is famous for are front and centre in this book too. As are those of his colleagues - especially Bloch and Lake who play a cracking part in proceedings. Harry is there, as usual, to try and steady the ship. Each knows exactly their roles and they all play then with aplomb.
As for the case - it is everything I expected and more. Convoluted, interconnected, with secrets, lies and dysfunctional behaviour aplenty as the author does a great job of obfuscating and sending the reader down a rabbit hole, followed by a swift about face.
But, and this warrants mention, as it doesn't happen very often in this series - I guessed something early! And I was chuffed to bits when I found out I was right :)
I actually can't praise this series enough. It is probably one of my top 5 all time favourites and, even at the grand old age of 10 books (plus inbetweenies) unlike other series I enjoy, this one has NEVER let me down.
I could bang on and on about how awesome it is. The plotting, the execution, the courtroom scenes, the characters, the twists, the stings, but I'd be here all day and, you know, books to read and all that! So... just get the book and read the book, you won't regret it.
My thanks go to the Publisher and Netgalley for the chance to read this book.

The 10th book in the fabulous Eddie Flynn series is here! In this instalment, the rich and powerful Patrick Vanderpool’s affair is a huge risk to his campaign for governor. And when the other woman is found brutally murdered, both he and his wife are the clear suspects.

With Patrick’s family empire behind him, his wife Vanessa is quickly put on trial and Eddie’s the man they want to represent her. But can Eddie trust her when she says it was her husband who killed Molly, and not her?

Steve Cavanagh has absolutely smashed it yet again! Honestly this series just gets better and better, and I am so addicted! Eddie Flynn is just the BEST lead character for me. He’s always several steps ahead of the most depraved criminals, and lawyers! And I love that I can just get fully absorbed in the story, knowing that it’s going to be a clever, twisty ride and that things won’t end up being what they first seem!

It’s always a comfort settling back into a new story with our usual favourite characters - Harry (and Clarence the dog), Bloch and Lake. I’ve missed them! And they’re as funny and brilliant as ever.

And as always with this series, I went on a wild journey with Eddie, from the first chapter which glimpses ahead to a sticky situation Eddie finds himself in towards the end of the trial, to him and his team wading through Vanessa and Patrick’s lies, to the final twist just when I thought we had all the pieces of the puzzle put into place!

Everything is so intricately and cleverly plotted so that we can’t possibly understand everything until the end - but Eddie, of course, notices everything and he always knows when he’s being lied to!

And the writing, as ever, is snappy, urgent, and compelling. You can feel what’s coming next, and it’s irresistible when Eddie gets one up on the prosecution and, well, everyone who’s against him!

I’m just obsessed with this amazing series and am just going for a small cry now that I have to wait another year for more!

thank you to NetGalley and Atria Books for the ARC!

I want to start off this review by saying this is easily the weakest Eddie Flynn book I've read... and it turns out, the weakest Eddie Flynn book is still like, quite good.

I think the main issue is the stakes in this series are simply getting too big at this point and the characters are getting into too many seemingly deadly, no-escape situations, and fighting their way out. Bloch and Lake have long wrecked ... ugh I can't believe I'm going to use this term ... the "power level" of this series. I like them enough as characters to give them a pass, but they can basically do anything and it's like, just a fact. but now Eddie is making crazy physically demanding (to say the least.) escapes too. I hope the next book goes a little smaller.

ok I've spent enough time complaining. this book has the same strengths as the Eddie Flynn series usually does, in that the story is insanely compelling and the court scenes absolutely crackle. unlike the physical fights, I never tire of seeing Flynn and company get themselves into inescapable situations IN COURT and seeing the super clever way they do get out of them.

also it's funny. a plot point was super bothering me THE ENTIRE LENGTH of this book. I can't talk about it without major spoilers, but I think anyone who reads this will immediately pick up on it from very early on as well. it bothered me significantly more than the fight stuff I mentioned above. I was fully prepared to come on here and complain as vaguely as I could. but then, at like literally 97% of the way into this book, not only was that plot point resolved, like four other plot points were also resolved. some of them I'd seen coming, but some of them I definitely hadn't!

Vanessa... girl. [salutes]

overall, if you want to read Eddie Flynn books, you can do better than this one. but you're still going to have a very good time.

Book 10 in the fantastic Eddie Flynn series, One Of Us Is Guilty explodes out of the gate with a gripping, high energy opening that immediately pulls you in. Told through a multitude of POVs, but it’s the perspectives of the two main suspects that truly hook you they keep you constantly questioning everything.
As always, the courtroom scenes are brilliantly written sharp, tense, and utterly compelling. Steve once again proves he’s at the top of his game when it comes to legal thrillers. But this time, there’s an added level of action woven throughout, giving the story an extra edge and making it even harder to put down.
The plot is incredibly clever, full of twists that will have you second guessing yourself at every turn. Just when you think you’ve figured it out, the story shifts and pulls the rug out from under you. I managed to guess one part of the twist and felt quite pleased with myself but the other completely caught me off guard.
Eddie himself is, as always, a master of outfoxing everyone around him. Watching him piece things together and stay one step ahead is a huge part of what makes this series so addictive. This might just be his best outing yet.
As always Harry, Bloch, and Lake are all standout characters who add depth and personality to the story. You can’t help but feel like you’d love to sit down with them all for a dinner party, how fascinating would that be?
The ending is absolutely first class smart, impactful, and perfectly executed. This is one of those books that completely takes over your time in the best possible way. Once you start, you won’t want to stop.
Im honestly surprised this series hasn’t been picked up for a TV adaptation yet.
While it can be read as a standalone, I’d highly recommend diving into the entire Eddie Flynn series to fully appreciate just how brilliant these books are.
