A couple disappears without leaving a trace—until suddenly, seven years later, their bodies are discovered. This case lands on the desk of Josie Quinn and her team.

With full dedication, she dives—both literally and figuratively—into the investigation. She’s determined to unravel this mystery too and give the grieving family and friends the answers they need to find closure and try to move on.

Knowing Josie, she leaves nothing to chance, and giving up is simply not in her vocabulary. She knows that a breakthrough will come if she just keeps digging.

When she finally figures out how everything fits together, I was shocked. This was truly an ending I never saw coming. It’s proof that the author has once again portrayed Josie and her team brilliantly.

But beyond Josie the detective, there’s also Josie the wife and the guardian. In her personal life too, there are still some issues that need to be resolved—and although it’s not all fixed overnight, there’s definitely progress.

The story is built up beautifully, becoming more complex and tense as it unfolds. The emotions are portrayed masterfully—you feel them deep within yourself.

The author paints a striking picture of how you think you know people, until you see what happens behind closed doors—and then realize you didn’t know them at all.

I’m more than ready for book 24 ;) I simply have to give this story 5 stars.

Thank you.

In The Couple’s Secret, Lisa Regan once again proves why she’s a master of the modern crime thriller. This 23rd instalment in the Detective Josie Quinn series is both gripping and deeply human, weaving a tale of love, loss, and the devastating consequences of secrets kept too long.

When the bodies of Tobias Lachlan and Cora Stevens are discovered in a submerged car seven years after their disappearance, Josie Quinn is pulled into a case that’s as emotionally charged as it is baffling. What begins as a tragic cold case quickly spirals into something far more sinister, as Josie uncovers layers of deception that fracture the image of a seemingly perfect couple.

Regan’s writing is taut and evocative, balancing the procedural precision of a seasoned detective with the raw emotional undercurrents of a family torn apart. The discovery of a mysterious key, the silence of grown children, and the sudden appearance of another body all build toward a climax that is both shocking and heartbreakingly inevitable.

What sets this novel apart is its emotional depth. Josie’s empathy and determination shine through, making her not just a detective, but a deeply relatable protagonist. The pacing is brisk, the twists are smart, and the tension never lets up.

The Couple’s Secret is a standout in an already stellar series—perfect for anyone who loves a mystery that lingers long after the final page.

With thanks to Lisa Regan, NetGalley and the Publisher for the ARC of this book in return for my honest review.

Tobias and Cora disappeared after going out to dinner. Seven years later they are found in a submerged car and it’s up to Josie and her crew to solve the mystery. Also they have just become guardians to Wren who seems to hate them. I enjoyed catching up with Josie and all of the other characters. Something happened towards the end of the book that has me anxious to read more. I highly recommend this series and this book.

Josie is tasked with figuring out what happened to the couple found in a submerged vehicle who have not only been missing for years but are from a distant town. As she interviews the children the couple left behind, she becomes more convinced that there are secrets and lies to be uncovered. It has so many twists and turns that just when you think you've figured it out, something else comes into play. Adding to the difficulty of this cold case, Josie and Noah are trying to find a way to connect with Wren, the teenager they took guardianship of when she lost her parents. This is a roller coaster of a read with all the hope for a relationship with Wren as well as the tragedies that unfold as clues are found. I did not even come close to figuring it out and that's my definition of a perfect mystery book.

When a seemingly perfect couple, Tobias and Cora, vanish after a dinner and their bodies are found years later,
Josie Quinn reopens a long-cold case filled with emotional complexity and buried secrets. A tiny antique key found in Cora’s purse becomes the chilling keystone to what unfolds — exposing hidden truths, distraught families, and a killer desperate to stay silent
Another great read by Lisa Reagan. The Josie Quinn series is one that you won’t be disappointed in.

Thank you to NetGalley and the publisher for an advanced copy for an honest review.

This latest Josie Quinn thriller was amazing. Josie and her team take on a case of bodies found submerged in a river, who turn out to have disappeared years ago from a town hours away. But they didn't drown - they were murdered before disappearing into the water. Who would want this couple dead, and why were they found so far from their home? The more she investigates, the more questions Josie has. And the more she realizes that even families that appear perfect can have plenty to hide.

The story was so enthralling, and the mysteries so layered, with many family members entangled in the secrets of the couple's past. They are the type of people who project one image to society, leaving their true selves exposed only to those closest to them. Josie and her team really have to dig into this family and get them to push past their loyalties to reveal their darkest secrets. It's the only way they will get justice for the victims. They may not be totally innocent, but they still deserve justice, and Josie always fights for that. It's why her character has such a high level of integrity. And once those involved start to spill, you won't believe how depraved some people can be!

I loved this book and recommend it to everyone. This is an awesome series that never disappoints.

The Couple’s Secret is another great book by Lisa Regan. This is book 23 in the Josie Quinn series and it just keeps getting better. You can read this as a standalone but I suggest going back and start with the first book, either way this is an amazing series. I highly recommend it, you won’t be disappointed. Thanks to Netgalley and Bookouture for this arc.

The Couple's Secret by Lisa Regan is full of mysteries, deep family secrets, and deceit. The Couple's Secret is part of Detective Josie Quinn book series. If you don't know Josie, you should. She is a strong female character that runs towards danger to protect the innocent. The Couple's Secret plot surrounds one thrown together family and the secrets that they all keep. The book takes you on twists and turns until the truth is finally uncovered but also leaves you feeling a little unsatisfied because you don't get all the answers about crimes that were committed 20 plus years ago. This book also shares a new side of Josie Quinn because she became a legal guardian along with her partner and co worker Noah. Josie knows how to be a detective but trying to "parent" a teenager has her stumped. I love this book series for a variety of reasons but if you are a fan of mystery/thrillers, you will enjoy this series. I also think these books can be read as a stand alone as well. Publication date is September 1st, 2025.


Thank you Lisa Regan, Bookouture, and NetGalley for the Opportunity to read and review this book.

The Couple’s Secret is another masterpiece by Lisa Regan.
You have a little romance, a lot of suspense and of course non-stop action.

Josie Quinn is probably one of my favorite series of all time.
This book has you believing one thing then at the end you find out what really is going on. Such a good read!
I stumbled upon Lisa Regan while looking for something to read and I was so excited to have found her.
Her writing is amazing and she doesn’t disappoint.

If you’ve never read Lisa Regan you are truly missing out.

Lisa Regan retains the streak of 5 Star Ratings in the 23rd Josie Quinn installment!

The Couple’s Secret delivers everything I have come to expect from this series.

Great mystery as Josie and team try to find answers to a cold case after the bodies of a couple, Tobias and Cora who vanished 7yrs ago are discovered in a submerged car in a river near Denton. There were no clues found in the initial investigation. The detective on the case now retired, only one key suspect was pursued over the 7 years. As the case progresses, there are questions relating to other women involved with Tobias and known to the prime suspect, could they all be linked in some way? Then, after the funeral, the daughter of Cora goes missing and is found dead at the spot where the car was found. What caused her death and was it by her own hands and a bottle of vodka or was she murdered, and if so, why? This investigation will have you hooked!

Add in our main characters and all that is going on in their lives. Josie and Noah are adapting to life post the aftermath of their last case, the fears the nightmares as well as new home dynamics as they welcome newcomers into their life (do not want to say too much or it could spoil things for those who are not up to this book yet). On the work front, Turner, closed off to the team when it comes to anything personal about himself of his life outside of work, he manages to provide some insightful contribution towards the case and Josie and Noah’s home life. We also find out a little more about him.

Above all, there is a beautiful, joyful ending that will have a smile on your face.

Tobias and Cora go out to dinner only to never be seen again. Now, seven years later the bodies are found in a submerged car. Their children were left behind and were devastated by the loss and had been looking for answers. Detective Josie Quinn gets called to the scene and sets out to determine what happened as somebody must know something.

Josie is also struggling as she is a guardian to Wren who she swears hates her. She has known loss in her life as is trying to connect with Wren and help her. Noah is still struggling with PTSD and they have planned a vow renewal so she is juggling many things at once. Josie is one of my favorite characters as she has gone through so much tragedy and keeps on pushing forward.

She digs into Tobias past and realizes he wasn't the saint everyone made him out to be. I loved all the side characters, family drama and how she slowly reveals the truth of what happened years ago. This would work as a stand alone but you appreciate more if you read the series.

Absolutely loved this book! Lisa Regan is a master storyteller! Mystery, intrigue, suspense all rolled into the story making it hard to put down! You won’t be disappointed!

I absolutely loved this story! This one focuses on a couple who had been been missing for 7 years before they were found murdered 3 hours from where they were last seen. This story had a lot less characters/suspects to keep track of than the last book, therefore making it easier to follow, (for me, anyway) and because of that, it made it a lot more interesting as far as trying to figure out who the guilty party was. And as always, getting more from the personal lives of Josie and all the reoccurring characters was the perfect balance to the investigation. I like that the author includes little reminders of who everyone is and how they came to be a part of the ongoing storyline, because without those, after 23 books in the series, I would struggle to keep track until they appear in more books. I really enjoy the interactions the detectives have with the newest member. There were several of them that made me laugh out loud. I can only hope we learn more about him in the next book since the ending left off with an oh shit moment about him.

Lisa Regan never misses - she pushes her characters more and more with each book - and it's absolutely fabulous to read. Josie and Noah are struggling with a new addition to their family, in addition to currently being on separate shifts. This book, Josie is paired with Gretchen, and it's fantastic to read their interactions and work on this case together. They are called do an old boat dock by the river where a car has been submerged for years - upon retrieving it, they find two bodies inside... and the case begins. After the couple is identified, the case takes many twists (in true Lisa Regan fashion) until it starts to unravel. Lisa Regan's Josie Quinn Series is one that cannot be missed - it's one of the absolutel best! Thank you to NetGalley and Bookouture for an advance reader copy of this book; the opinions expressed are my own.

This is #23 in the Detective Josie Quinn series but can easily be read as a standalone.

There’s enough of Josie’s personal life to be interesting without taking away from the main story. Josie and Noah have just become temporary guardians to Wren, a teenager, and are trying to navigate their way around this new situation.

When the water level of a lake lowers, the remains of a car are revealed. Inside are two skeletons who turn out to be an engaged couple – Cora and Tobias – who went missing seven years ago, leaving their blended family of three teenagers behind. It appears that they were shot, so Josie has to investigate a cold case murder, and it’s not easy.

Thank you to NetGalley and Bookouture for an advance reader copy in return for an honest review.

As always, Lisa Regan DELIVERS! Not only a plot that has you chasing your own tail, own thoughts, and then second guessing them bit then delivers the biggest bomb of a conclusion... boom!

I must be honest, because that’s what we’re here for! This is the first one of the whole series that actually took me a little while to fully immerse myself in. It didn’t feel like the previous installments. It wasn’t as full on, BUT once I was sucked in, I was completely in!

A car has been found, submerged in a river in Denton. A river that is usually flowing high, but due to the first drought they’ve had in years, has now been discovered. Josie, being Josie, takes it upon herself to dive in and recovers the number plate, which leads back to a missing persons case from seven years previously. When the car is recovered, remains are found, both with bullet holes in the skulls.

Among the debris in the car, Cora’s purse is also recovered. Inside is a tiny skeleton key. But what did it fit and why did Cora carry it with her?

Seven years ago, engaged couple Cora and Tobias disappeared after a night out, leaving three teenagers, Cora’s daughter Riley and Tobias’s sons Jackson and Zane, without their parents. The children have lived the past few years in limbo, hoping with a small thread that one day they’ll return, and now that hope has been crushed.

Can Josie, Noah, Gretchen, and Turner get the results they need to get justice for this couple, or has too much time passed?

On a more personal level, Noah is still struggling with PTSD (book 22), and Josie is desperate for him to get help. With them now guardians to Wren, they have a lot to live up to.

I’m really hoping that we’ll soon find out more about Turner, he wasn’t a huge part of this story, apart from the sprinklings of ‘douchebag’ 🤣 but an added surprise at the end makes me think we’ll finally start learning some more. Lisa is a master at character development, as we’ve seen with Josie from the very beginning,  I just need a little patience.

This was a real rollercoaster read with plenty of red herrings, twists, suspense, and a lot of emotion thrown in. And for once, I didn’t have the slightest clue how it would end!

Huge thanks to Netgalley and Bookouture the ARC.

Can you keep a secret?  This novel does!

Lisa Reagan's The Couple's Secret focuses on one secret that most couples already know: Relationships are hard! While Noah and Josie are evolving in their relationship after some recent traumas, they are also building a relationship with a new additions to their family. Meanwhile, Josie and Gretchen are solving a  seven-year-old murder mystery that leads to a web of other mysteries, all tied to strained relationships. Regan reminds us again of the importance of familial bonds, teamwork, and telling the whole truth.

I’ll say it again and again, Detective Josie Quinn is my absolute favorite!!! And 𝙤𝙛 𝙘𝙤𝙪𝙧𝙨𝙚 Lisa Regan, does not disappoint. This book was worth the wait!!! Please do us both a favor and add this series to your TBR..

Thank you NetGalley, Bookouture and Lisa Regan for the advance copy!!!

This book had me hooked from the very first page. The mystery of Tobias and Cora’s disappearance was chilling, and the twists just kept coming. I thought I had it figured out—then Lisa hit me with another curveball! Josie Quinn is such a strong, relatable character, and every case she works pulls me deeper into her world. The emotions in this one hit hard—grief, secrets, betrayal—it had everything. I couldn’t stop turning the pages. Highly recommend for anyone who loves a smart, gripping detective thriller with heart.

When a drought lowers the water levels in the river, a submerged car is discovered with two skeletons inside. The bodies are identified as a couple who went out to dinner seven years earlier and never returned home. The case was never solved. It’s also determined that they were murdered. Since the car is discovered in Denton’s jurisdiction, Josie and her team are assigned to reopen the cold case and determine who killed the couple and why. There are a few possible suspects. As the clues start to add up and secrets come to light, another member of the family is found murdered and Josie is determined to get justice. The deceased couple weren’t the only ones hiding secrets. Twists, turns, lies, betrayal, and so much more!

On the home front, Josie and Noah are still trying to make positive progress with Wren, but she isn’t helping matters at all.

The teaser at the end regarding Turner having a teenaged daughter named Cassidy, leaves us eagerly awaiting the next book in the series.

I voluntarily read and reviewed an advanced copy of this book. All thoughts and opinions are my own.
