DS Liam Kilshaw #2

The Replacement

Rate this book
A body on the beach. A myth come to life. And a killer who won’t stop…

When a mutilated body washes up on Sennen Beach, DS Liam Kilshaw is plunged into a case as dark and unforgiving as the Cornish winter. With the victim’s face so severely disfigured that identification is impossible, whispers of a local superstition begin to surface—the killing bears a chilling resemblance to the legend of Bucca Dhu, a vengeful sea demon said to demand human sacrifice.

But myths don’t murder people. When a second body is discovered just above the high-tide line, Kilshaw knows he’s racing against time. A missing crew member, a lost shipping container and a trail of cryptic clues all point to something far more sinister.

In a place where folklore and reality blur, Kilshaw must uncover the truth—before the killer strikes again.

Liam gets a call about a horrifying new crime. Someone has found a body on the beach, trapped in a bag and horribly mutilated. Someone is luring young men into a trap and murdering them in this disturbing way. There are concurrent chapters in which we are given insight into the insane perpetrator. Then there is another identical death, and the team is racing against the clock to prevent another grisly murder.

This is the third book which I have read by Matt Brolly, and Book 2 in the DS Liam Kilshaw series, and I must admit, he’s becoming a huge favourite of mine. I didn’t read a synopsis before opening the book, I just saw the title and author, and immediately had to read it.

A body sealed in a hessian bag washes up on Sennen Beach, with horrific injuries to his face, and it’s not long before there are reports of young men going missing in the surrounding areas in Cornwall. They all have the same thing in common, they all resemble each other…dark haired, handsome, and in their twenties. When a second body is discovered, with the exact same facial disfigurement, sealed in a hessian bag, DS Liam Kilshaw, races against time to find the killer, before another body is found.

This is another gripping, page turner, which also contains some Cornish folklore, which I was excited to read, as I do love the “old ways”, and the tales, which are believed by some throughout the towns, all over the world.

Thanks to the author Matt Brolly, Thomas & Mercer, and NetGalley for providing me with this free ARC, with which I leave a voluntary review

3.5. / 5.0

Not a bad book for a starting series, there’s still a lot of development and area to work but it’s a great series. It’s easy to follow, whilst there is mentions of the events of the previous book, there’s enough to follow and understand the team dynamics. I’d say there’s still quite of Liam Kilshaw that we as readers are yet to uncover but I’m invested on how the character will develop along with the series. The police procedural is definitely up there, but at points it’s not as convincing. An example is the discovery of a connection is more so told as opposed to finding that out, which felt slightly forced in a way. Other than this moment, things naturally progressed and developed - hoping that the next book in the series will avoid that pitfall. I found the character development of Liam Kilshaw to come across natural and logical as well - which I’ve found in a few books now unnatural it can be when that happens.

When a mutilated body washes up in Sennen Beach, DS Liam Kilshaw is plunged into a case that’s as dark and unforgiving as the Cornish winter. With the victims face so severely disfigured that identifying the body is nearly impossible, whispers of a local superstition begins to surface of the legend of Bucca Dhu - a demonic sea demon said to demand human sacrifices. When another body is discovered just above high tide line, Kilshaw is up against time. With a missing crew member, a lost shipping container and a trial of cryptic clues all point to something even more sinister. It’s up to Kilshaw to uncover the truth before the killer strikes again.

Overall, it’s not a bad book. It’s an interesting one, the main points are that the logic follows and makes sense. The actions of the character makes sense for their character at that moment of time as well. It’s a series I’m intrigued in. It’s not perfect, but the series looks promising.

This is the second installment in the DS Liam Kelshaw series. While I did read the first book, I believe this could be enjoyed as a standalone novel, although there are numerous references to the previous story. Liam is a divorced former Marine suffering from PTSD stemming from a near-drowning incident during his service.

A maimed body encased in a hessian bag washes up on the Cornish Coast and Matt and his team are on a race to discover the culprit and stop any more killings. Could it be, as someone suggests, related to an ancient legend of giving sacrifice to Bucca Dhu, a water spirit with the power to generate storms?

Brolly weaves a captivating blend of myth and psychopathy in this gritty, fast-paced, and suspenseful read. Set during the unforgiving winter in Cornwall, the atmosphere is palpable. His vivid descriptions of the snow and cold evoke a strong desire for a blanket! Liam is an interesting character, and I particularly like the working dynamic between him and his boss, Maya.

It’s all go once again for DS Liam when a body is washed up in a hessian sack down at Sennen Cove.
I loved this one. The story telling was rice and combined folklore in the story adding an extra dimension to the story. I loved how so unhinged some of the characters were as their story developed through the book. This one is paced really well and I absolutely flew through it.

Book 2 in the DS Liam Kilshaw series. A good read though not quite as ‘edge on your seat’ as book 1. Not loving the main characters in the series as they seem a bit 2 dimensional, would be nice if the author gave them a little more character. Good unusual storyline.

Thank you to NetGalley and Amazon publishing uk for the arc of this book in exchange for an honest review

ARC review - Matt Brolly’s The Replacement opens with a disturbing image—bodies found in burlap bags with their faces badly damaged—and it pulls you in right away. From there it follows a steady investigation led by an investigator who refuses to give up, which keeps the story moving at a good pace.
What stayed with me most was the broken family at the center of it all. A mentally ill, controlling mother and children who have each been affected in different ways create this constant sense of discomfort. It adds feeling to the story without getting in the way of the plot.
This is a dark, fast read that’s easy to get through in a short time. Some moments are hard to read, but it keeps your attention, and it’s a solid choice if you enjoy crime stories with complicated families and plenty of tension.

After reading The Lines as part of a book tour last November and really enjoying it I knew I immediately had to request this when I saw it on Netgalley and it definitely did not disappoint!
I loved the duel POV and the chapters from Alex's POV were so good giving just enough about his captivity to keep you invested while giving nothing away. This was a slow burn but once it got going I couldn't stop reading. The way it all came together was so well done and the reasons behind everything was just so twisted Again in this, like book 1, I loved Liams character, his PTSD and the difficulties he has with loneliness etc make him so relatable and you just want him to be happy, his RNLI took a backseat in this which again is so lifelike while investigating multiple murders but I hope this returns a bit if there is another book written.

I was thrilled to read The Replacement by Matt Brolly. It features Detective Sergeant Liam Kilshaw. Set in and around Bodmin in Cornwall, England, this police procedural and crime novel is a great addition to the series.

A mutilated body washes up on Sennen Beach and Liam arrives to start the investigation during a dark and cold winter. The victim’s face is severely disfigured making identification difficult and the killing bears a resemblance to a folklore legend. However, myths don’t murder people. Clues point to a race against time when a second body is found.

Liam is a former marine and Special Boat Service member who suffers from post-traumatic stress disorder after his breathing apparatus failed and he nearly drowned on a mission. However, he is doing better than he was. He had always loved the water and is volunteering with the local lifeboat team as a type of immersion therapy to help himself (along with his breathing techniques). He tends to keep people at arm’s length, but is working on that. He cares about others and enjoys a decent relationship with his ex-wife and son. He’s also relentless in his pursuit of those who prey on those who are vulnerable and immerses himself in the cases. However, this causes him a work-personal life balance issue.

Once again, the author starts the story with a chilling prologue that immediately grabs a reader’s attention, but readers don’t quite know how it pertains to the current timeline. Throughout most of the story, there is a sense of urgency as the investigators try to make sense of what has happened and what may happen. While the story ensnared me from the beginning and the ending was action-packed, the middle is solid police work, but slower paced.

Told from the alternating perspectives of Liam and one other person, it will keep readers fully engaged. There are several twists and turns giving readers the opportunity to test their investigative skills as the police search for answers, including motives, relationships, and who is behind the crimes. The author also does a great job of creating atmosphere that makes it easy to feel like you’re with Liam hunting for answers. Secrets, folklore, murder, isolation, and relationships co-exist in this disturbing storyline.

Overall, this was a gripping, gritty, and chilling story with complex characters. This atmospheric thriller has a strong sense of place and a terrific cast of characters. I’m looking forward to reading the next book in the series. Those who enjoy police procedurals, this author, and British crime dramas will likely enjoy this series.

The Replacement by Matt Brolly is a highly recommended procedural and the second book in the Detective Sergeant Liam Kilshaw series following The Lines. It can be enjoyed as a standalone novel. Kilshaw, a former Marine, is a intuitive investigator who also suffers from PTSD and has alopecia.

When a body in a hessian bag (burlap for US readers) washes up on Sennen Beach in Cornwall, DS Kilshaw is called out to investigate. The face of the man in the bag is so mutilated identification is almost impossible. Kilshaw takes note when a local man brings up the legend of Bucca Dhu, a sea monster who demands human sacrifice, but clearly this is the result of human depravity. When a second man's body is found on the shore also in a burlap bag with the face beaten beyond recognition, it is clear that a serial killer is at work. Kilshaw must use all his skills to find the perpetrator before another body is found.

The opening prologue will immediately attention grabbing and also provides the reader a brief glimpse into what may be related to what is currently happening. Set during the winter in Cornwall, the atmosphere in the novel is literally chilling in words and deeds. The narrative unfolds through the point-of-view of Kilshaw and another person, who's viewpoint will keep your attention focused even when the investigation slows the pace down in the middle of the plot. The anticipation over what may happen next is ever present in this even-paced procedural and there are several twists along the way. The ending is, as expected, action packed.

Kilshaw's character development continues in this second novel as he works on his interpersonal relationships, a skill with which he struggles. He is portrayed as a realistic, complicated individual with strengths and weaknesses. He has a good relationship with his boss, Maya, his ex-wife and tries to makes sure to see his son George. Additionally, thank you Matt for making sure the dog was okay, which may be a spoiler for some but other readers will want to know this.

The Replacement is a great choice for those who enjoy British procedurals and investigations set by the sea. Matt Brolly is always a dependable author who writes compelling stories. Thanks to Thomas & Mercer for providing me with an advance reader's copy via NetGalley. My review is voluntary and expresses my honest opinion.

DS Liam Kilshaw Book 2. After finishing and loving Book 1 last week, I had to jump right into the next. Available on KU!

This dives right into a harrowing discovery: a mutilated body washed up on Sennen Cornish beach, stashed in a hessian bag. The victim's face is severely disfigured, making identification impossible. Whispers within the town bring an old legend to life, Bucca Dhu—a vengeful sea demon demanding human sacrifice. However, when the second body appears, just as disturbing as the last, it's clear to DS Kilshaw that no folklore is killing these people; he has a serial killer on the loose. This mystery needs to be solved before the next victim turns up.
I inhaled this one like an addiction, listening to it at any given moment. With such an enticing start, I was hooked.
As an avid police procedural reader, some themes can become common, but this had a highly unique and chilling premise. There was a crosshatch between the heinous crimes and Cornish folklore, which really piqued my interest and added depth to an already well-layered plot.

I really enjoy this author's writing style and flow. The narrator also does it justice, and I find myself totally absorbed.

This predominantly follows DS Kilshaw and his relentless detective work. He's passionate about his police career and pushes all boundaries to solve the case. He is a flawed detective with a tormented past, which often reflects his relationship problems, both historical and current. A divorced former Marine suffering from PTSD, the author does an impeccable job at crafting a well-rounded, likable male protagonist that appears authentic with traditional values. I'm invested in his character.

I was captivated by this sinister case; it's disturbing, graphic, and deliciously grim. The descriptive language is vivid and raw. I easily imagined the maimed bodies stuffed inside the hessian bags, and it made my blood run cold. The harsh Cornish winter setting complemented the gruesome scenes and added pure ferocity to the tale. The woven-in POV from the psychotic perpetrator was a creepy interruption, scary, and did the trick.

Fast-paced from the start, every meticulous detail made me fall deeper into the conundrum. This cleverly executed story came with a very satisfying ending. I'm eager to jump into the next, but Book 3 isn't out until 28.04.26! 🤯

I read this book as an ARC from NetGalley and this review is my honest feedback based on my completing it.

I read this as an advance copy and waded into it expecting a dark coastal crime novel having read another book by Matt earlier. What I got was something even more layered and quietly unsettling. The Replacement leans heavily into atmosphere and mood and that is where it truly shines. From the opening discovery on the Cornish shoreline there is a sense of dread that can confuse readers to feel this is a horror novel, that never quite lifts. The sea feels hostile, the community feels closed off and the story wastes no time letting you know that this will not be a comfortable read.

Matt balances police procedural detail with a creeping sense of folklore and unease. The narrative moves between perspectives in a way that keeps the tension simmering rather than exploding too early. I especially appreciated how much restraint there is in the writing. Instead of relying on constant shocks Matt allows silence, memory and implication to do much of the work. This is very much in line with the kind of crime novels I tend to enjoy and recommend in my Goodreads reviews where atmosphere and character psychology matter just as much as plot mechanics.

The characters are bruised, believable and often frustrating in very human ways. The lead investigator carries emotional weight that informs his decisions and reactions even when those choices are questionable. At times the story revisits these personal struggles a little too often and a few emotional beats feel repeated rather than deepened. This slightly softens the impact but never enough to pull me out of the story entirely. I would have liked a bit more tightening in the latter half but the emotional stakes remain strong right through to the end.

Overall this is a compelling and moody crime novel that trusts the reader to sit with discomfort. The coastal setting, the moral ambiguity and the slow burn tension all work together to create something that feels both bleak and thoughtful. Fans of darker crime fiction who enjoy character driven stories will find plenty to admire here.

Four stars for a novel that lingers long after you close the book.

4* Another good story, but when oh when will Liam make his life more meaningful, real? Will he make his father's mistakes?

Book 2 in this very good police procedural series can be read as a standalone. There's enough mention of Liam's past in drips and drabs to clue new readers in. It picks up shortly after the scary ending (for the almost-girlfriend, his son George's teacher, whose name I've forgotten just minutes after she appears in the penultimate chapter) with Liam giving her space.

It's quite clear that Liam's heart sort if thinks it lies elsewhere, in his past, which as this book ends, might also end up lying in book 3 - I'm hoping the 'lying' doesn't turn out to mean bad decisions lying. I hope he treads with caution as there's something about Grace that raised red flags in book 1, and here, the police professional body feel the same, although by the end of the book, she's back in favour. And far more local. Liam isn't entirely using his big head where she's concerned, buying a burner phone to contact her whilst the professional investigation is ongoing and whilst he's still being questioned. I'm not sure he's capable of long-lasting feelings or a relationship. His head's far too much in his past with his parents' mistakes, but he's not that far off the., putting work first, disappointing his son and rightly irritating his ex.

The storyline is freaky but you don't see the baddies until right at the very end, other than the glimpses in the prologue. The book should've featured them a bit more given the unique premise and twisted mindsets of more than one generation. How social services didn't pick up on things requires a bit of suspension of disbelief.

Still, it's a decent read, though emotionless.

Review copy was received from NetGalley. This does not affect my opinion of the book or the content of my review.

Liam Kilshaw is our point of view for almost everything.  He's a former Marine with PTSD after being caught underwater and almost drowning.  He still loves the sea and is a member of a lifeboat rescue team.  He has a son but never married the mother as he was stationed away.

Liam is contemplating his life as men in their 20s turn up on or near the sea and badly beaten in cloth bags.  He wonders who would notice if he were missing as some of the men are reported missing and some are not.   It's difficult identifying the men and then trying to piece together their last known timeline with family and friends.

Liam enjoys spending time with his son George. Mostly he spends all his time otherwise working with thoughts of dating.  He doesn't seem to know how to make a strong, regular connection with a woman right now.

The case is dark and grim with a lack of useful evidence. They do a great job of combing through videos from different kinds of cameras to find cars and people to match witness statements.   I'm definitely looking forward to more in the DS Kilshaw series.  Next up is Broken Circle in April.

Narration:
I appreciate the same narrator continuing with the series.  The emotional tones and accents felt appropriate.  The speech was clear with the voices distinct.  I listened easily at my usual 1.5x speed.

I love British detective stories, so I'm always glad when I find one. This is the second book in the DS Kilshaw series, but you don’t have to read the first to enjoy this one. The author puts in plenty of references to first book that help you understand Liam Kilshaw.

The story starts with a creepy situation where a girl is having her doll sewn up in a “hessian” bag - I didn’t know what this was so I found out it’s a “strong coarse bag made of jute or burlap.” Apparently, the fabric was used to make uniforms for the soldiers of the State of Hesse in prewar Germany - hence “hessian.” By sewing up the doll she will be forever enshrined as she was that day. From there the story switches to Liam who’s taking over a case of missing men when a mutilated body of one shows up in a hessian bag. I will say Liam and his fellow officers are dedicated as they find clues - not a lot of red herrings here, just good procedural stuff. If you want to know more, you’ll have to read the book. It will be worth it.

The book is nicely written. Liam’s a well developed character — I liked him and sense that more books are coming. The book is also paced nicely. I enjoyed the book; it’s a good mystery.

I’d like to thank NetGalley and Thomas & Mercer for allowing me to read this book.

The Replacement by Matt Brolly, published by Amazon Publishing UK, is a powerful second instalment that proves this series has real staying power. It delivers everything I hoped for and more, especially the welcome return of characters I was so pleased to revisit.
At the centre of the story is DS Liam Kilshaw, a protagonist who continues to grow in depth and complexity. There is something incredibly compelling about the way he approaches his cases, determined, flawed, and human. His interactions with those around him add both tension and warmth, and it is these evolving relationships that give the series its emotional backbone.
The plot itself is gritty and tightly constructed, full of intrigue and steadily building suspense. Just when you think you have a handle on what is unfolding, another layer is revealed. Yet amid the darkness, there are moments of dry humour that feel natural and well placed, giving the reader brief pauses for breath without ever undercutting the seriousness of the investigation.
This second book feels confident and assured, deepening the world and strengthening the character arcs. For fans of character-led crime fiction with edge and intelligence, The Replacement is a thoroughly satisfying read.
My thanks go to Netgalley and Amazon Publishing UK for the ARC of this book.

I listened to this as an ARC audiobook from NetGalley, and since I hadn’t read the first book in the series, I did find it a bit challenging to fully connect with the characters right away. It felt like I was stepping into an already-established world, and it took some time to get my bearings and understand the relationships and dynamics.

That said, I’m really glad I stuck with it. As the story progressed, I became much more invested in both the characters and the outcome of the mystery. The plot itself is genuinely intriguing, with enough twists and reveals to keep things engaging without feeling overdone or unrealistic.

The pacing is definitely on the slower side compared to what I usually prefer, but it works in the book’s favor. Matt Brolly does a great job of building tension gradually and maintaining a steady sense of suspense throughout. Even during the quieter moments, I still felt compelled to keep listening and find out what would happen next.

Overall, this was a solid and well-crafted mystery. While I think reading the first book beforehand would have helped with the initial connection to the characters, this still stands on its own as an engaging and worthwhile read. I’d definitely consider going back to the beginning of the series or continuing on with the next installment.

When a mutilated body washes up inside a hessian bag on a Cornish beach, it’s just the start of a difficult murder investigation for DS Liam Kilshaw. Even once the victim is identified as a missing man, it’s a tough case to crack with no obvious motivation for his death. Local Cornish myths and legends play a part in the way the man was killed and suggest a very warped mind is involved.

Liam’s personal life is also not easy. Divorced from his wife, he sees his son, six year old George whenever he can, but sometimes work gets in the way, which he hates. He was in a new relationship with Millie, a teacher at George’s school, but after she was kidnapped and nearly drowned, she has been struggling with PTSD and wants to keep some distance from Liam and his job.

Eventually long hours and dedicated police work by Liam and his boss Maya will find some answers, but it will be a race to the finish line to catch the perpetrators and may be too late for another victim. This dark and disturbing crime in the depth of an icy English winter is atmospheric and creepy. Mostly related by Liam, the cast of characters, subplots and twists maintain a good pace and deliver a gripping tale. 4.25★

Set in Cornwall, descriptions of the locations give a good impression of where scenes are playing out. A young man is found dead in a hessian sack on the beach. His identity is not immediately apparant and when it does become known, he does not have much contact with his family. There are also first person accounts of a young man being kept prisoner in a cave. He is enchanted by his captoress, Adelaide . Liam, the detective does not have much to go on but gradually the plot and reasoning behind it emerges. Liam has a habit of taking risks when investigating, which may put him in difficult situations.
Although this book is a fairly slow burn without too much physical action and is told from different points of view, it is not difficult to sort out the different voices and the plot was engaging enough to keep my interest throughout. Towards the end the suspense builds up and I had to stay up to finish the book. Number 2 in the series, Liam and his circumstances are familiar, though I`m not sure if I read the first book or not. It is fine as a stand alone though.
Thanks to Net Galley for the ARC. A great read

A mutilated body on a Cornish beach. A whisper of ancient superstition. And a detective chasing shadows through winter’s gloom.

Matt Brolly’s The Replacement is a moody, myth-tinged thriller that blends folklore with forensic grit. DS Liam Kilshaw returns in a case that’s as chilling as the sea wind off Sennen Beach. With echoes of Bucca Dhu—the vengeful sea demon said to haunt the coast—this story dances between legend and reality, never quite letting you settle.

Kilshaw is a compelling lead: sharp, haunted, and quietly relentless. As the clues twist through missing crewmen and cryptic symbols, Brolly’s prose remains taut and evocative, painting Cornwall in shades of grey and dread. The pacing is brisk, the atmosphere immersive, and the mystery satisfyingly layered.

Perfect for fans of coastal noir and folklore-infused crime fiction, this is a tale that lingers like sea mist—unsettling, beautiful, and hard to shake.

Time to revisit DS Liam Kilshaw for his second novel, “The Replacement”. I loved the first novel, “The Lines” and could not wait to see how the characters would continue to grow. I had no clue we were in for a second book so soon.

Matt Brolly does not disappoint with this atmospheric novel.

A body is found (in what amounts to a potato sack) with much abuse from the water and in general. So much abuse, they can’t tell who it is. DS Kilshaw and his team begin the investigation to see who the deceased is. As this goes on, another body appears.

Between the investigation and personal issues, life begins to pile on DS Kilshaw. The question is, will he finally crack the case, or crack himself.

I have become a big fan of this series and am hoping for a 3rd novel soon. My only complaint is there are a few times it just felt a bit repetitive. Near perfect novel. It was so good, I went through it in one day.

I received this ARC from NetGalley and the publisher in exchange for an unbiased review.

4.5 stars out of 5 stars

This is the second book in the DS Liam Kilshaw series, and I would recommend reading book one (The Lines) first in order to fully appreciate Liam’s backstory: his struggle with PTSD following an apparatus failure, which lead to him almost drowning during his time as a marine. This book also touches on key points from the investigation in book one.

The story gripped me from the off! From the chilling prologue I knew I was in for an exciting and gruesome read – I loved the inclusion of Cornish folklore. It’s easy to get lost in the atmosphere of an unforgiving winter in Cornwall, and the authors description of the snow and cold created a tension I could almost feet. The tale is told from the alternating perspectives of Liam and one other person, so it allowed me to keep guessing as to where we would go next. We also see Liam’s character development continue and he becomes more likable – more human, as he works on his personal relationships. All in all, this is a riveting, chilling and atmospheric thriller. Highly recommended.

Thank you to NetGalley for the ARC of The Replacement by Matt Brolly

This was a gripping and atmospheric crime thriller that drew me in immediately. Set against the harsh Cornish coastline, the story is steeped in local folklore, with echoes of ancient myths and sea legends adding an unsettling undercurrent to an already chilling investigation. The folklore never overwhelms the narrative but instead deepens the sense of place and menace in a really effective way.

What stood out most for me was the strength of the characterisation. DS Liam Kilshaw is a thoughtful and convincing lead, and the emotional depth given to both the investigators and the wider community adds real weight to the story. The plot is tightly constructed, with twists that feel earned, and the bleak winter setting mirrors the darkness of the crimes perfectly.

Although this is part of a series, it worked brilliantly as a standalone and never felt inaccessible. This was my first book by Matt Brolly, and it certainly won’t be my last. A richly layered, immersive and highly satisfying read. An easy five stars.

Chilling, compulsive and captivating! Matt Brolly never disappoints and the highly anticipated second instalment in the DS Kilshaw series is an absolute triumph!
When bodies are discovered in a hessian bag on Sennen beach Cornwall, Liam and Maya are thrust into a high-stakes race against time and a looming Cornish winter, desperately trying to prevent another murder.
The real heart of this series lies in Liam’s character. His journey of recovery, his empathy and his well meant occasional forays from the rule book make him deeply relatable. The friendly banter with Maya cements them as a formidable duo who will back each other to the hilt.
The pace ramped up in the second half, keeping me reading into the wee small hours to reach a nail biting ending that ties up everything as neatly as one of those hessian bags wrapped in a bow. 
An atmospheric, expertly plotted must-read!
My thanks to Netgalley and the publisher for the privilege of an advanced copy. This is my own opinion.
Release date 10 February.

The Replacement follows DS Liam Kilshaw, a former marine struggling with PTSD, as he investigates mutilated bodies washing up on Sennen Beach.

I love how this author's books keep me on the edge of my seat! (I really enjoy his Louise Blackwell series as well.) The Replacement is definitely not a warm and fuzzy book, but one that is a fast-paced police procedural. It's easy to care about Liam and the rest of the team he's part of. I very much appreciate the fact that there isn't a "token person" on the team who is hateful, as there sometimes seems to be in some of the other books I read. I must confess that the freezing cold weather I was reading about made me grateful I was under my electric blanket as I read! I've got the next book on my Kindle, so I must go. I can't WAIT to see what happens next!

For some of my friends who are as soft-hearted as I am:

This is the second book in the DS Liam Kilshaw series. It's set in Cornwall and he is faced with a series of bizarre ritualistic murders of young men.

I haven't read the first book in the series and it didn't impact my reading at all. I didn't feel like I was missing anything or I didn't understand things. I will still probably go back and read book one at some point.

I liked the Cornish setting, it was very natural and I loved the references to the Cornish legend of Bucca Duh which was woven into the story.

It was well paced with interesting characters. Definitely looking forward to the next book.

Books one and two are already out and book three is coming out in April.

Thanks to NetGalley for the book

Prolonged Suspense

Whenever I read a Matt Brolly novel, I know that I'm in for an unusual and breathtaking adventure. I've read all of the Louise Blackwell novels, and now the Liam Kilshaw books are proving to be just as good.
In THE REPLACEMENT, Liam is attempting to identify two bodies that were found sewn into Hessian bags and mutilated beyond recognition. What he doesn't know is that a mother and daughter team is committing these acts because of a bizarre belief that the person sewn in the bag will live forever. Without giving away any spoilers, this is another wonderful police procedural that Brolly is so good at. I had to stay up late to finish this one so that I could breath again. Excellent read!
