The Peasedsle Woods K i l l e r s series has definitely been enjoyable one. Book 3 dove into Mason’s character, alternating between past & present. The past before he was caught & now life after prison under his new identity.

The past chapters were very challenging as Mason was just a kid, forced into a life a crime he did not want to be a part of. It really makes you feel bad for Mason despite him being an accomplice for so many young boys’ demise. He was truly just a victim as well!

This story definitely brought a fresh perspective, as we have already seen The Other Boy & The Other Mother’s POVs in books 1 & 2. This was a great read, and addition to this series. I received a free copy of this book via Booksprout and am voluntarily leaving a review.

Third book in the Peasedale woods murders.

This installment gives us Mason's story. The chapters alternative between past and present giving us a better idea of what life was like for Mason when he was younger. He didn't seem to stand a chance against Gunner and I think he lacked the sense to tell a responsible adult what was going on. His immaturity and experience of being treated poorly by his teachers and stepdad means he was exceptionally vulnerable.

Present day Mason is figuring it out and I think he's still stuck in some way. He has the naivety of someone much younger and his decision making is somewhat floored. You can't help but feel sorry for him and that there's a sense of inevitability about his present and future.

This is a great series but some people may find it a hard read due to the content.

After reading The Other Boy and The Other Mother over the last few months - and loving them! - I'm back with the third and final book in The Peasedale Woods Killers series.

 

Now, although this book could read fine as a standalone, the storyline does continue on from the previous books and I feel that you'd definitely get more from this if you read the series as a whole.

 

So, we come back to Mason, now two decades on and he's just released from prison and trying to navigate life outside - trying to start a new life and be better.

But almost as soon as he settles, bad things start to happen and it's soon clear that someone knows who he is and they want their revenge.

 

Obviously, the setting here is quite different from the previous reads, but I have been so invested in this series that the eerie atmosphere follows on and I think when you know someone could be stalking you, there's always that I comfortable feelings as you're reading and just waiting for the next thing to happen.

 

The writing style gripped me from the start and I was again sucked into this world and I couldn't put this down.

I'm pretty sure there were large chunks where I felt like I was holding my breath or not even blinking - as I raced through this so fast.

 

After everything, I still couldn't help feeling for Mason and really hoping and rooting for him throughout.

 

Another great read and a great series as a whole.

I'm excited to read more from this author and see what will come next.

The third and final installment in Field's Peasdale Woods Killer series, The Other Killer was an eagerly anticipated read for me having thoroughly enjoyed the two previous books.

Twenty years on since the last book sees Mason having been released from prison. This was his redemption. However ghosts don't always stay buried forever...

With chapters giving us insight into the past of a life littered with woes, a mother's love never waned.

A gripping page turner full of twists and turns with an added layer of emotion I didn't see coming. A satisfying end to what's been a great series.

Another intriguing and exciting story in this series. I would recommend you read this series from the beginning. It is incredibly intense with mystery, suspense, and surprises. Ms. Field has done an excellent job with this series and I will definitely be looking forward to more of her works.

This series has been amazing and this book - wow!
I didn’t expect to feel as emotional reading this as I did, the characters have a way of getting to the reader and writing draws you in and doesn’t let go.
A thriller yes, but this is so much more we get to see Mason twenty years on and out of prison, it’s hard not to give too much away but I was completely invested in his story and his relationship with his mother.
You could probably read these as standalones but I think to get the full picture you need to read all three, you will not be disappointed they are reads that will stay with you.

You can change your name…
Change your life…
But someone knows exactly who you are…

Book three in The Peasdale Woods Killers series takes us twenty years after Mason was imprisoned as an accomplice to Gunner - the man responsible for the brutal crimes against the boys. 📚

Now he’s finally out… but not as Mason. 🙋🏻‍♂️

Under a new identity - Jace, he’s desperate for a clean slate, a second chance, a life far away from the horrors of his past. With his mum’s help, he’s been set up with everything he needs: a new phone, a fully furnished apartment in Duldridge, and enough supplies to get him started. 🏢

Everything should be different this time… 🙌🏼

Some chapters also take you 20 years back, before Mason’s arrest, revealing how he became entangled with Gunner and how it all began. 🤨

But can you really escape a past like that… or is it only a matter of time before it catches up with you? 🤔

I absolutely loved this book - it was so intriguing, it completely pulled me in! I was totally hooked from start to finish. 📖👀

Packed with twists and turns, utterly gripping and emotional, with a fantastic ending to The Peasdale Woods Killers series! 🤯

Heidi has done a fantastic job - each book in the series just keeps getting better and better! 🤩

Huge thanks to Heidi and Zooloos Book Tours for letting me be part of the tour. I’m so happy I got to continue this series! ♥️

First, I want to thank Heidi Field, Tule Publishing and Zooloo Book Tours for providing me with this book so I may bring you this review.

DANG!!! If you are not reading Heidi Field’s The Peasedale Woods Killer Series what are you waiting for?! Seriously, she has instantly become one of my favorite psychological thriller authors. Each book in the series has been better than the next. However, The Other Killer, the final book in the series, was Heidi’s best of the best. Heidi was able to answer a lot of questions us readers had from past books.

Croco Designs did a great job creating the cover for The Other Killer. It created that creep factor.

I highly suggest that if you have not read Heidi’s other two books in the series The Other Boy and The Other Mother that you do so. You will get a better idea of the characters and the backstory. If you read this one before reading the other two books you may be a little bit lost. Not to mention those storylines are so deep, dark and twisted!

So, If you read the other books in the series then you are in for a treat in The Other Killer! In this book we get the opportunity to meet Mason after he gets out of prison and see the man he has become. On the flip side Heidi takes us back to where it all first started and how he landed in prison. We also get to meet Gunner himself. This is the book the fans have been waiting for to hear his side of the story!

Heidi got a little spicy this time around with Mason and Gracie. Then again cooped up all those years with no female interaction yeah he deserved that night. Then again on the flip side mention he did get some male fun in prison. Only to later find out he was groomed by Gunner for that act as a kid. Which was a lot to take in.

One of the recurring themes in the book was second chances. Mason made a point in every situation to be a better man in every situation. Sometimes he succeeded and sometimes he could have done better.

Heidi had so many incredible twists and turns in this book that it was crazy!! Especially the intense climatic jaw dropping ending that left me speechless!! Never saw that one coming!! The Other Killer is another book to add to your growing TBR list!! This is a series people should be talking about because it is an amazing series by a truly talented author that has a gift in this genre!!

I have been waiting for this to arrive and oh my it did not disappoint me. This is book 3 in the The Peasedale wood killer. To be honest you can get away with reading them as standalones.
I absolutely adore this author, I have devoured this series. It definitely gave me every tense motion I have ever had. This is addictive, thought provoking, breathtaking, it is perfect 👌
It has been a phenomenal read and can’t wait for the next book that Heidi writes.

Psychological thrillers are one of my favourite genres, so I’ve read a lot of them over the years. It was refreshing to find one that broke away from the typical tropes, as the story is told from the perspective of an antagonist. I love a dual timeline and it was interesting to read the then and now which gave insight into past motivations and present fears.

This can be read as a standalone in my opinion, as I didn’t feel I missed too much. I’ll rely on other bookworms to tell me whether having read the third book first will remove the tension of the unknown in the previous novels.

A great read for those enjoying morally dark characters and tension you can cut a knife with!

Book 3 in The Peasedale Wood Series.
I loved Books 1 and 2 and could not wait to read this one.
20 years ago, Mason Tucker was tried and convicted as a teenager who helped the serial killer, The Pied Piper of Peasedale.
Now Mason is released from prison and changes his name.
But has he changed?
A great series....and now starting book 4.

This is book 3 in the Peasedlse Woods Killers series, normally I would want to read a series in order but something really drew me in with this book that I couldn’t refuse the chance to give it a go. It is now safe to say I really am interested in going back and reading the others now!

A read that unsettled and unnerved me to the core, yet I was hooked and hanging on to every word. I like my dark reads, so this was exactly up my street, but I could imagine it could be very unsettling to some.

The short chapters kept me racing through the chapters and I loved that we followed the main character through his past and his present. It was an addictive book and I couldn’t help but tell others about it. I wasn’t ready for the ending at all, I had so many unanswered questions, that I was left wanting and needing more! A brilliant psychological thriller.

Here’s my review for The Other Killer by Heidi Field

I thoroughly enjoyed reading book three, The Peasedsle Woods Killers which was a superb psychological suspense thriller. I was hooked right from the very beginning of the book and I found I just couldn’t put it down. It was so easy to read and get into! I have totally loved all the books in this series. In this book, Mason has served his twenty years prison sentence and is now a free man. His mum has set him up with a first floor flat, in a new town, he gets a job that he enjoys doing on a building site and he feels like he has a new purpose in his life. His new name is Jace Grayson James. Someone watches him leaving prison. He has a near miss with a car that clips his hip. He receives photos from someone showing the shack, the prison and a couple of others but who sent them? Who is after him? This story was excellently written, extremely well plotted and brilliantly thought out. Jace was an intriguing character as he was trying to stop his past from resurfacing, and he was trying to stay out of trouble, but it seemed to come to him. Could he being stalked? He had aged well, filled out through working out and the ladies liked what they saw. He had to keep his wits about him. This was a ‘now’ and ‘then’ story which are the type of stories I really love reading. I could feel the suspense in the story as I was reading it. The characters were interesting and well described. I would like to read more books by this author in the future.

Blurb :

You can change your name. Change your life. But someone knows exactly who you are.

Twenty years ago, Mason Tucker was tried and convicted as the teenager who helped lure young boys to the serial killer known as the Pied Piper of Peasedale. After serving his twenty-year sentence, Mason is freed and hopes to remain invisible while he rebuilds his life as an adult, hoping to become a man he can be proud of. A new town, a new flat, a new job and a new purpose.

But living with secrets is challenging, and protecting his anonymity, the woman who stood beside him, and her child becomes impossible when the past pushes back. Hard. Within days of his release, Mason suspects he’s being stalked. He’s threatened and twice attacked. He never imagined being outside would be more dangerous than being in prison. The police aren’t an option. One headline will destroy him.

Someone wants him punished, not redeemed, and as danger closes in, you will never suspect where the next threat comes from.

The Other Killer is the final book in Heidi Field’s The Peasedale Woods Killers series. I have read all three books and would not recommend reading the final book without reading the first two. The book was very gripping and compelling. It is well written and also because of all the feelings it coaxed out of me, I’ve given it 5 stars. This is Mason’s story and told from his perspective. It begins 20 years after the first book, however it is told with chapters alternating between the past and present. We learn more of the gruesome story where an evil man forced a teenager to take part in the killings of so many innocent teenage boys. The book lets us see another side to Mason and his fears, regrets and feelings both in the past and now.

As the story begins, Mason has been released from prison after serving his 20 year sentence. He has a new name as Jace, an apartment in a different town and a job at his mother’s company doing construction work. He witnesses a young kid across the street from his place, being ignored by his mom and abused by his stepfather. Jace offers to help the boy fix up his bike and gets him food when his parents aren’t around. The stepdad is not happy about Jace and looks into him. Jace reconnects with Shiv, the woman who visited him in prison for 20 years and who is the daughter of the serial killer. She is divorced and has a teenage son who is filled with anger and doesn’t like Jace. His new life initially goes okay and then Jace senses someone stalking him and others suspect his real identity. Things go sideways fast and suddenly Jace’s second chance looks to be in jeopardy.

The characters are well created by Heidi. In spite of everything that Mason/Jace has done, the reader can’t help but feel saddened for his bad choices and his tragic situations in life. His mother has been a source of support to him for all his years and her life has also been tragic. The descriptions of the serial killer’s actions are truly disturbing and Jace presents his situation in the past as hopeless. The ending of the book is shocking and there are surprises throughout the story. If you are a fan of thrillers, this is a series I would recommend.

I was fortunate to receive this ARC from Tule Publishing Company in exchange for my honest review.

There’s something quietly powerful about a story of second chances, and The Other Killer by Heidi Field delivers exactly that with a strong emotional core that lingers long after the final page.

Set twenty years after the events of Book #2, we meet Mason as he is released from prison for crimes he was involved in as a teenager alongside Gunner. Having only read the previous book, I can honestly say this one still stands strong on its own. Heidi Field does a great job of grounding the reader, allowing you to slip into Mason’s world without feeling lost or overwhelmed by backstory.

What unfolds is a deeply human story. Mason is trying , really trying to rebuild his life. He forms connections with Gunner’s daughter and grandson, Pip, and even takes young Kenny, the kid across the road, under his wing. Watching him attempt to carve out something meaningful for himself, including securing a stable job, makes you root for him from the beginning. You want him to succeed. You want him to be more than his past.

But of course, the past doesn’t stay buried forever.

As tensions rise and old shadows begin to creep back in, Mason’s fragile new life is put at risk. The outside world isn’t always ready to forgive, and that’s where the emotional weight of this story really hits. I found myself genuinely feeling for Mason especially as he once again loses everything, all in the name of love, echoing the tragedy of his earlier life.

One of the standout elements for me was Mason’s relationship with his mother. In a genre where family ties are often fractured or toxic, this was refreshingly different. Her unwavering love and support, even through his twenty years in prison, added such a heartfelt layer to the story. She never turned her back on him, and that kind of unconditional love brought warmth and depth to what could otherwise be a dark narrative.

Overall, The Other Killer is more than just a thriller ,it’s a story about redemption, resilience, and the enduring power of love. It’s raw, emotional, and incredibly human. If you enjoy character-driven thrillers with heart, this is definitely one to add to your list.

The Other Killer ~ The Peasedale Woods Killers #3 by Heidi Field

Having followed The Peasedale Woods Killers series from the beginning, I can confidently say that The Other Killer is another strong, compelling instalment. Heidi Field delivers a well-crafted narrative that is rich in suspense and intrigue, maintaining a steady sense of tension throughout.

This third book continues the story of Mason, who has spent the past twenty years in prison for his involvement as an accomplice to the child killer Gunner. The plot is engaging from the outset, drawing the reader in with its layered storytelling and carefully developed characters.

Without revealing any spoilers, I would recommend reading the series in order to fully appreciate the overarching narrative and character progression.

Overall, The Other Killer is a gripping and well-written crime thriller that will appeal to readers who enjoy dark, suspenseful fiction. Highly recommended.

The Other Killer #3 by Heidi Field

Alright… first things first—thanks Heidi and BookSprout. Really. Nothing says “great reading experience” like emotional damage that lingers a little too long after you’ve closed your Kindle.

Also, let’s not pretend you can just jump into this one like a chaotic gremlin. If you haven’t read The Other Boy (#1), don’t be that person. Go back. Do it properly. Otherwise you’re just ruining it for yourself, and honestly? That would be a crime.

Now that we got that out of the way…

Mason.

Yeah. Him.

Because apparently I went from absolutely not to well damn… now I feel things. And I hate that for me.

Let’s be clear—what he did? Not okay. Not even a little bit. But this book forces you into that uncomfortable corner where you start asking the annoying questions. The ones you don’t want to ask because they mess with your clean, judgmental little worldview. He was 14. Fourteen. Kids don’t just wake up and choose chaos for fun. There’s always something underneath. And once you start seeing it… you can’t unsee it.

And somehow—against my better judgment—I felt it. His fear, his anxiety, the constant weight he’s dragging around. I understood him. I even understood his mother. And that realization? Yeah, that one stings a bit. Because it’s messy and morally inconvenient and not nearly as black-and-white as we’d like it to be.

This book doesn’t hand you answers. It hands you questions and then watches you spiral.

Second chances… do they even exist? Or is there a point where you mess up so badly that no amount of time, regret, or good intentions can fix it? What if you’re already marked? What if the past doesn’t just follow you—but owns you?

Cute thoughts to have before bed, right?

And then the ending.

I was this close to launching my Kindle across the room like it personally betrayed me. Heart = shattered. Expectations = laughed at. Emotional stability = gone. It felt unfair. It felt wrong. And maybe that’s exactly the point.

Because every good intention, every attempt to do the right thing… just spirals anyway. And you’re stuck there, feeling it all, like an unwilling participant in a slow emotional car crash you can’t look away from.

So yeah. Five stars. Not because it was “nice” or “enjoyable” in a cozy way—but because it made me feel everything I didn’t sign up for. It got under my skin, messed with my perspective, and refused to let go.

And honestly? That’s the kind of story that sticks.

Just… be warned. You might walk away a little less certain about who the real villains are.

I really enjoyed book 1& 2 in the Peasedale Woods series by Heidi Woods so I was delighted to get a copy of the last in the series.
The Other Killer is Mason's story , he has a new identity , having been released from prison, and is enjoying a labouring job . However someone is stalking him and he plans to find out who it is .
Very intense script , as the author Heidi Field takes the reader back to the time of Mason's offending , with the alternating chapter focusing on his present life.
This has been a riveting series but I would say content may be triggering for some families .
Recommend to anyone who enjoys psychological thrillers.

I think my only issue with the third book in the series is that it is written entirely from the point of view of Mason Tucker, known ‘as the teenager who helped lure young boys to the serial killer known as the Pied Piper of Peasedale’. Initially he is drawn in because the killer threatens to kill his mum if he doesn’t help him procure his victims. But the question is how far would you go to protect someone?

In Mason’s position, I think most people – even a child – would go straight to their mum, tell her what’s going on, and go together to the police. Report the weirdo and ask for protection. But then Mason is different and it started with the rabbit.

So is he fundamentally evil? If you’ve read The Other Mother you will know what happened to his sister Lily. His behaviour then was already not normal.

I have to say I can’t warm to him or forgive him. And I don’t like Shiv either. I think she is manipulative. Having married, had a son Pip, separated from her husband, and waited 20 years for Mason to be released from prison, you would think she would want to distance herself from all of it for the sake of her son. He’s also not very nice, but who can blame him.

And then there’s neighbour Kenny. Yes, he has an alcoholic, useless mother, and dreadful stepfather who beats him, but the last thing Mason should do is befriend a teenage boy, not with his history.

But I really enjoyed the book, in spite of everything I’ve just said. It’s been a great series and I would read another chapter, but I’m not sure there is anyone left!

Many thanks to @ZooloosBT for inviting me to be part of this blog tour.
