The Devil’s Code
A BRUTAL MURDER
When Isaac McFadden is found with the dismembered body of a young man in the boot of his car, it’s an easy conviction for the jury. But, then a notebook is discovered in Isaac’s house, and the police believe they have a serial killer on their hands.
A CRYPTIC CODE

Dr Olivia Winter is a forensic psychologist whose job is to understand the minds of serial killers.
This time around she’s brought in to help DI Linus Sutton of Northumbria Police, who believes they may have a serial killer on their hands.
Isaac McFadden was driving along the A1 near Newcastle when he was pulled in by the police, and when asked to open the boot of his car, he seemed awfully reluctant. The reason soon becomes evident, because Isaac has bags of body parts in there!
A search of his home reveals a journal that points to him being a serial killer. The journal shows pages of cryptic clues, alongside what appears to be trophies of his victims, and DI Sutton, Olivia, and assistant DC Ryan Sweetland, are really going to be tested by this horrific case.
This is a chilling read, with the tension becoming unbearable at times, but it’s deeply engaging and thought provoking, not to mention very clever. It goes without saying that it is well written (Well Michael Wood wrote it)! Highly recommended.
*I was invited to read The Devil’s Code by the publisher and have given an honest unbiased review in exchange *

4.5⭐️ rounded up.
Well done, Michael Wood! This series deserves way more attention than it gets, it’s so good.
Olivia Winter, a forensic psychologist and final girl who survived being stabbed multiple times by her serial killer father, is a compelling character. She’s flawed by her traumatic past yet portrayed with realism. Strong and resilient but also vulnerable and weighed down by survivor’s guilt, she feels authentic and complex.
No need to repeat the book’s synopsis since it is already well stated without giving too much away. The plot is clever, and although I was mostly able to work it out by the end, I still wavered a few times in my prediction. Olivia’s perspective is fascinating as she profiles a serial killer and, in this installment, works to unlock a cryptic code believed to reveal the locations of more bodies. The killings are quite brutal, so this one is definitely not for the faint of heart.
While this can technically be read as a standalone, I highly recommend starting with the first book to fully understand Olivia’s traumatic past. The Devil’s Code had me hooked from the very first page all the way to the last, and now I can’t wait for the next installment. In the meantime, while I impatiently wait for book three, I’ll be diving into his DCI Matilda Drake series, which I’ve heard is also excellent. Highly recommend!

It’s dreadful weather and Isaac McFadden is driving on the A1 in the North East listening to The Big O when he sees blue lights flashing behind him. Has he been speeding? Will he be over the limit? A fraught conversation ensues resulting in the officer realising Isaac does not want him to see what’s in his boot and Isaac appreciating that he shouldn’t have gone out tonight. The game is up.
14/12/24
At his trial, Isaac is inevitably found guilty. Has a serial killer in the making been foiled? Discoveries made by his daughter Eleanor suggests otherwise and she calls DI Linus Sutton who enlists forensic psychologist Dr Olivia Winter to interpret what has been unearthed. Olivia is a survivor, can her ‘luck’ hold? She’s looked evil in the eye and lived.
If you’ve read Michael Wood before, you’ll fully appreciate the anticipation of starting a new novel. I didn’t think he could better the Matilda Darke series which I love but I think he might have hit the jackpot again with this one. It grabs me right from the start, keeps my attention fully engaged and takes me on a dark, fast paced rollercoaster ride of twists, turns and shocks in another brilliant chiller of a thriller. There are so many layers to it as well as the obvious investigation pursued by DI Sutton, Olivia and very able assisted by DC Ryan Sweetland who I hope we meet again. There is a clever, devious, horrifying puzzle to crack that requires them to be at the top of their game and places them in great danger.
It’s very much character driven, obviously central is Olivia and I find her increasingly fascinating as the past very much impacts on her, she carries a great deal of pain and is permanently on her guard. Perhaps the only person she can fully relax with is her partner Sebastian Lister at the Behavioural Science Administration and I really like their relationship and the trust that lies between them. Stanley the dachshund is also very important in her life.
Another interesting layer is the impact and fallout of Isaac‘s crimes on his daughter Eleanor and how she handles this burden. Nobody knows how they would cope when placed in a terrible situation such as Eleanor finds herself in and she’s very conflicted.
I like the ‘true crime’ angle too which gives much food for thought and as this type of drama is becoming increasingly common on tv, the storyline here makes you think of its ramifications.
Overall, Michael Wood has knocked it out of St James Park and nicely set us up for Number 3. If you are a fan of mystery thrillers and haven’t read this author before, what are you waiting for?!
With thanks to NetGalley and especially to HarperCollins, One More Chapter for the much appreciated arc in return for an honest review.

Oh my word! The Mind of a Murderer was my first Michael Wood book, and since then I have started his Matilda Drake series. I have eagerly been waiting for the second Olivia Winter book, and The Devils Code did not disappoint. This book is brilliant, just so clever and so addictive. I do enjoy a serial killer case and these books are just detailed and thought provoking.
Olivia is drawn into a case in Newcastle, when a journal is discovered in the home of Isaac McFadden by his daughter after his arrest and incarceration. Isaac was pulled over and bags of body parts were discovered in his boot. Now it seems that was not the first of his crimes. In the notebook is a cryptic code, that along with the box of trophies, have Olivia determined to find the truth.
I loved that Olivia was working with a different team this time. DI Sutton and DC Ryan Sweetland were both really interesting characters, and the 3 of them worked really well together. All of them have their demos, Olivia more than anyone, but they use them together to find the clues and try to crack the code.
Olivia is still and always will be dealing with her past, and a TV drama about her father about to air is hard for her to avoid. Losing herself in a new case is just what she needs. I love learning more about her and look forward to more in book 3. These books are intense and extremely dark and messy, just as I like them.
Another easy 5 star read from a new auto read author for me. Thank you so much to Harper Collins UK, One More Chapter for introducing me to Michael Wood. Publishes on March 28th

Michael Wood is a fantastic writer and he proves it yet again in The Devil's Code.
Dark, gruesome, tense, gritty, it delivers on so many levels. It's not just the brilliantly thought out, original story but the characters that Wood gives us are brilliant, fully fleshed out too, especially dr. Olivia Winter. She might be the poster girl for the 'final girl', she might still be affected by the survivor's guilt, but she's one tough cookie who you just cannot help but to cheer on.
I absolutely love those books and can't wait to see what's next for Olivia Winter.

I enjoyed the first Olivia Winter book so glad to start another one. With no progress indicator on, I was surprised how long this book was but I enjoyed taking it page by page. Good writing and solid characters. I am not sure how I felt about the perp and there were some good twists and turns by the end. I will definitely give the next one in this series a try as soon as it’s available!
Thank you both Netgalley and the publisher for the opportunity in exchange for an honest review.

This time Dr Olivia Winter is tasked with deciphering a mysterious notebook found in the home of a suspected serial killer. Slick and cleverly done once again. I did work it out but still enjoyed the journey!

This is the second book in the 'Dr. Olivia Winter' series, both 5 star reads.
I love it when a thriller manages to hook me up, drag me into some pretty disturbing stuff, and mess with my mind. And that's what this book did.
Dr Olivia Winter is a forensic psychologist, also known as a 'final girl', because she previously survived two killers (read volume one for this). She is asked to help understand the mind of another murderer by DI Linus Sutton, after the police found a dismembered body of a young man in the boot of Isaac McFadden's car. But then a cryptic notebook is found in his house and the police believe they have a serial killer on their hands.
This was such a fun ride. Olivia gets to use again her wonderful mind to understand what was written in that notebook and hopefully catch another serial killer. It had some reveals that I did not guess and it ended up being more complex that I thought it would be.
It was suspensful, mysterious, messed up and so well written. A really captivating read.
I will definitely read the next volume.

I’ve just finished reading this book and oh boy what a rollercoaster. It’s second in a series but can absolutely be read as a stand alone. It’s got twists, it’s got turns, it’s got blood, it’s got body parts. What more could you possibly want?! I also gave book one 5 stars, so if you’re a thriller lover, crime procedural connoisseur or a serial killer binger, please pick up this series. 100% for fans of Chris carters Robert Hunter series.
Also, what a way to end the acknowledgments. When the hell is book 3?!?!

Forensic psychologist and serial-killer researcher Dr. Olivia Winter was introduced in The Mind of a Murderer. The survivor of a serial killer--her own father--Winter has dedicated her life to finding out what makes killers tick.
Isaac McFadden is on his way to dispose of a dismembered body when a routine traffic stop catches him. He is uncooperative and is quickly convicted of the killing. Then, McFadden's notebook is found, containing a code indicating he may have killed multiple times. Unable to crack the code, the police turn to Olivia to try to get McFadden to open up about the killings and to help in solving the code. Olivia's noted professional reputation and her personal history have drawn unwanted attention and distracted her from her investigation. This, combined with a manipulative McFadden, makes Olivia's task all the more difficult.
I am a fan of Wood's DCI Matilda Darke series, and this series is proving equally enjoyable. As with all of his books, this is a dark and chilling read. It is also suspenseful with good twists and excellent characters. I highly recommend this book and author. 4/5 stars.

Really good read, if you have an interest in serial killers and not upset by blood and body parts its pretty good.
June 16, 2025
It took soooo long for the clues to be revealed, and even so, they were uncovered circumstantially & not through clever deduction. And God that throwaway Eminem reference “will the real xxx please stand up”- so cringey 😭 There are so many unnecessarily mundane details that add nothing to the plot. The characters are also not particularly interesting. I’m sorry to say that this lacks many elements of a good detective/murder mystery novel.

Doctor Olivia Winter, forensic psychologist specialist in serial killers (and daughter of a serial killing father who also tried to kill her) is back to help with a new investigation in Newcastle. Issac McFadden is pulled over during a storm and the police find a dismembered body in his trunk. Is this his first kill? Or are there more victims to find?
PROS and CONS:
Doctor Olivia Winter is back in this sequel to Mind of a Murderer (fantastic book - I couldn’t read it fast enough!). This one, while still well written and definitely a thriller, is a bit slower than the last one. A code is discovered during the investigation, and figuring it out occupies many pages in this one - while interesting, it wasn’t quite as compelling as tracking a serial killer’s current movements, etc. Still enjoyed and can’t wait to read #3 when it comes out!
READ IT?
If you’re into graphic police investigations featuring serial killers, then this one’s for you!
4 Stars

Thank you to NetGalley and Harper Collins UK One More Chapter for allowing me access to an ARC of The Devil's Code by Michael Wood. I was beyond excited to read this book after loving book one in the Dr Olivia Winter series.
I am a huge fan of Michael's Matilda Darke and standalone novels., having read all his published books, he is a brilliant author. You know what you are getting from his novels they are dark, complex and character driven.
In this series the main protagonist is Dr Olivia Winter a renowned Forensic Psychologist, an expert in the minds of serial killers. As the daughter and survivor of the serial killer Richard Button she is making it her life's work to understand what makes someone become a serial killer.
In this book DI Linus Sutton from Newcastle asks her to assist with the Issac McFadden case a killer who has recently been convicted of killing Sean Bridger after his car was routinely stopped and bags of body parts were discovered in his boot.
The book is fast paced with twists and turns, red herrings and occasional humour which leads you through this page turner to a tension filled conclusion.
Absolutely brilliant and nicely set up for book three.

My first 5 star of the month! The second Dr Olivia Winter instalment and I am hooked. Olivia, basically a serial killer hunter, goes to Newcastle to help the police with another case where a recently convicted killer has left a tricky code as well as some trophy’s pointing to more victims. I was so impressed with myself solving some of the code before I got to that part in the book. I also had a strong inkling of who the killer was but there was a few red herrings. A great read, I cannot wait for the next one and to add more Michael Wood books to my shelf! His writing is perfection in this series.

5 stars without a doubt. Book 2 in the Olivia winter series. Olivia is a forensic psychologist who I’m book 1 we learned a lot about. Her job is to get into the kind of serial killers. This book was crazy good. And crazy. I cannot recommend this series enough. Book 3 just came out so I will be reading that one.o. Please excuse the typos. I am vision impaired.
April 23, 2026
I had hoped that I would like this book better than book 1 because it has such a high rating but unfortunatly I didn't. I don't think these are bad books they just don't do anything special and the main character makes very stupid decisions for someone supposed to be that smart. I don't think I will read book 3.
September 21, 2025
I absolutely loved the first book in this series and when I tell you that this one, tops it by a mile!! The Devil’s code was so clever and so well plotted. It’s probably one of the darker thrillers I’ve read this year and would absolutely recommend it. It was so good and I will be recommending this series to everyone.

3.5⭐️
Hmmm, I have such mixed feelings writing this review because I really loved The Devil’s Code overall, but the ending left me a little conflicted.
The characters were fantastic and honestly one of the strongest parts of the book. They felt well developed, engaging, and easy to invest in, which made the story really enjoyable to follow. I was completely pulled into the plot and found myself eager to keep reading to see how everything would unfold.
The pacing and tension throughout most of the book were great, and I loved the ideas behind the story. It kept my attention and made it hard to put down. However, similar to the first book, the twist at the end was predictable. I had a feeling early on about where things were heading, and unfortunately it ended up playing out exactly that way.
That said, the predictability of the twist didn’t ruin the experience for me. The journey getting there was still really entertaining, and the characters and storyline were strong enough to keep me invested the whole time.
Overall, despite the somewhat obvious ending, I still really enjoyed this book and would definitely recommend it.

Audio version of this 📕- A great addition to the series

I figured out the killer’s partner within the first few chapters, yet somehow Olivia—the so-called forensic genius—misses the world’s most obvious clue parade. Does she solve crimes or just narrate them in hindsight like a crime podcast with amnesia?
She barrels through the case with zero self-preservation, like surviving The Last Girl gave her a god complex and a death wish. Her choices scream “main character immunity,” not “top-tier psychologist.” And Michael… what happened? This isn’t even the shadow of Matilda Darke’s sharp, gritty excellence. It’s like her boring cousin showed up to cosplay detective and forgot the plot.

I’m a huge fan of Michael woods books. They veer towards the darker side of crime, but my god the author sure knows how’s capturing the readers’ attention from the off. You can read The Devil’s Code the second book in the series, as a standalone. But I would recommend you read both. The Devil’s Work is a dark, often brutal, gripping and unsettling psychological thriller that is nigh on impossible to put down.
The book follows forensic psychologist Dr. Olivia Winter as she faces her toughest challenge yet: deciphering a coded notebook linked to suspected serial killer Isaac McFadden, found with a body in his car. McFadden’s case grows increasingly complex as the notebooks suggest more victims.
Olivia, still haunted by Survivor guilt, faces her own vulnerabilities as she delves into the mind of the suspect. Her character brings emotional depth and resilience to the narrative, which is complimented by Michael Woods’ hallmark suspense. The coded notebook at the heart of the narrative adds a layer of mystery which I appreciated keeping the stake high and the tension palatable. It also gives the reader the opportunity to play an ‘arm chair’ sleuth and decipher the codes alongside Olivia.
Michael Woods cements his reputation as a master of crime fiction writing. He balances a gripping police procedure with the psychological exploration of a flawed and dangerous, manipulative serial killer’s mind. McFadden’s character actually gave me a couple of nightmares!!! And I call myself a hardened crime thriller reader. The pace is relentless, fuelled by unexpected twists and dark revelations. I absolutely loved The Devil’s Code, and this is a must read for fans who enjoy a dark crime thriller.

I’m a huge fan of Michael wood’s books. They veer towards the darker side of crime, but my god the author sure knows how’s capturing the readers’ attention from the off. You can read The Devil’s Code the second book in the series, as a standalone. But I would recommend you read both. The Devil’s Work is a dark, often brutal, gripping and unsettling psychological thriller that is nigh on impossible to put down.
The book follows forensic psychologist Dr. Olivia Winter as she faces her toughest challenge yet: deciphering a coded notebook linked to suspected serial killer Isaac McFadden, found with a body in his car. McFadden’s case grows increasingly complex as the notebooks suggest more victims.
Olivia, still haunted by Survivor guilt, faces her own vulnerabilities as she delves into the mind of the suspect. Her character brings emotional depth and resilience to the narrative, which is complimented by Michael Wood’s hallmark suspense. The coded notebook at the heart of the narrative adds a layer of mystery which I appreciated keeping the stake high and the tension palatable. It also gives the reader the opportunity to play an ‘arm chair’ sleuth and decipher the codes alongside Olivia.
Michael Wood cements his reputation as a master of crime fiction writing. He balances a gripping police procedure with the psychological exploration of a flawed and dangerous, manipulative serial killer’s mind. McFadden’s character actually gave me a couple of nightmares!!! And I call myself a hardened crime thriller reader. The pace is relentless, fuelled by unexpected twists and dark revelations.

The Devil's Code is fast paced, chillingly good and you will want to devour it all in one sitting.
Dr. Olivia Winter who studies serial killers ( almost of victim of not one but two serial killers) is back and investigating one of her toughest challenges to date.
Olivia is dealing with her own battle wounds but when she is brought in to investigate the killer Isaac McFadden and she is determined to solve the mind boggling code he had written down.
Olivia is convinced to break the code will lead them to many other victims.
The atmosphere is tense and with every twist and turn, every body that is found you will be locking your doors and looking over your shoulder.
The Devil's Code is not for the faint hearted and is devilishly clever.
Expect the unexpected with Michael Wood.
You just never know.
My only complaint is I did not want the book to end and I will patiently for Olivia's next intriguing case.
Thanks to NetGalley and Harper Collins UK, One More Chapter for the privilege of reading and reviewing The Devil's Code.

This is book 2 in a series. I love the premise of Olivia be the daughter and survivor of a serial killer. Book 2 has Olivia aiding in an investigation once again and meeting new colleagues. Without giving too much away this was a new dimension for me regarding serial killer dynamics in method so not for the faint of heart be warned. I enjoy this writer and will continue to read this series I highly recommend him though the blood was a little much for me. Thank you NetGalley for this ARC!!

The only regret I have is that I wish I read this more slowly. Thoroughly enjoyed this.
