Pick up the first in a BRAND NEW Scottish crime series from bestselling author Daniel Sellers. A must-read for fans of Aline Templeton and Matt Brolly. 🔍👀🩸 Knapdale, Argyll. A place of beauty, tranquillity… and murder

When newly promoted DI Anna Vaughan is called to a case in remote Knapdale, on the Argyll coast, she welcomes the chance to escape her life in Glasgow - more specifically the mother-in-law from hell…

Ellen McIver, Baldrishaig’s local busybody, has been found dead. Run over — repeatedly — by a tractor belonging to local farmer Glen MacGibbon. The most likely culprit is Old Wullie, MacGibbon’s elderly father, who, despite his dementia, still likes to drive the tractor about the lanes. But once at the crime scene Anna can tell something sinister is afoot… this was no accident. Whoever drove that tractor did so with murder in mind.

With the help of local DC Jo McLean, Anna leads her first murder case as a DI. She soon finds that all is not as it should be in this corner of the Scottish Highlands. The locals have been living under a cloud of fear for months, and as Anna starts to uncover secrets buried for years, she is in a race against time to find a murderer hiding in plain sight.

Fans of Aline Templeton, Caro Ramsay and Marion Todd will not want to miss this brand new, gripping Scottish crime series.

First and foremost, a large thank you to NetGalley, Daniel Sellers, and Boldwood Books for providing me with a copy of this publication, which allows me to provide you with an unbiased review.

Always eager to experience history and crime through the lens of a new-to-me author, I turned to this series debut by Daniel Sellers. Set in Scotland, this gripping police procedural immediately hooks the reader with its layered storytelling, vivid setting, and a compelling new lead detective.

Following her promotion, DI Anna Vaughn is reassigned from Glasgow to the remote coastal community of Knapdale in Argyll. Eager to escape both the city and her increasingly difficult mother-in-law, Vaughn hopes for a quieter posting. That hope is quickly dashed when she arrives to investigate the brutal death of Ellen McIver, whose body was found repeatedly run over by a tractor. McIver was widely disliked and had no shortage of enemies, making motive easy—but answers far more elusive. While suspicion initially falls on an elderly local man, something about the crime scene and the town itself feels off. Teaming up with local DC Jo McLean, Vaughn soon discovers that the Highlands are steeped in secrets.

Ellen McIver herself had been investigating mysteries of her own, keeping cryptic notes that may hold the key to her death. Meanwhile, Vaughn’s mother-in-law has gone missing, and authorities are suddenly interested in her connection to an incident in London. As these threads begin to converge, Vaughn must determine whether cracking one code might expose a killer desperate to keep the truth buried.

Sellers delivers a confident and engaging thriller that balances multiple storylines without ever losing focus. The police procedural at the center provides a strong backbone, while carefully placed subplots add depth and intrigue. With brisk, mid-length chapters, the pacing never falters, and once the story gains momentum, it’s hard to put down. Each narrative thread feels purposeful, drawing the reader forward with the promise that everything will eventually click into place.

The characters are a particular strength. DI Anna Vaughn is a well-drawn protagonist whose personal baggage and professional instincts complement one another nicely. She’s surrounded by a strong supporting cast, each bringing their own perspective and expertise to the investigation. Rather than serving as background filler, these secondary characters actively enrich the mystery, adding texture and tension through their choices and motivations. Sellers clearly understands how to make characters work in service of both plot and atmosphere.

The plot itself steadily builds, offering well-timed surprises that enhance tension and keep the reader guessing. While the murder investigation remains front and center, additional revelations emerge organically, deepening the story and expanding its scope. Twists are thoughtfully executed, taking the narrative in unexpected directions without feeling forced.

This was an impressive introduction to Daniel Sellers and a promising start to a new series. With sharp writing, a compelling lead, and an evocative Scottish setting, this novel delivers everything I look for in a strong thriller. I’m eager to return to the Highlands and see what lies ahead for DI Anna Vaughn.

Kudos, Mr. Sellers, for a wonderfully Scottish police procedural.

Set in Scotland, this gripping police procedural immediately hooks the reader with its layered storytelling and beautiful setting, Daniel Sellers is a new to me author. I will definitely read more by this author.

Following her promotion, DI Anna Vaughn is assigned to investigate a suspicious death in the remote but stunning coastal community of Knapdale in Argyll. Ellen McIver, the local busy body, has been found dead and not only that she has seemingly been run over by a tractor...repeatedly. McIver was widely disliked and had no shortage of enemies. Teaming up with local DC Jo McLean, Anna, soon discovers that the Highlands are steeped in secrets. Simmering beneath the peaceful village of Knapdale we come across suspicious deaths, petty crimes, and a whole host of secrets just waiting to be discovered.

I loved the rural, remote setting. This is one of those places where every body knows everyone's else's business. Gossip spreads around the villagers faster than the police can investigate the crimes. Being in a tight community in an isolated setting is the perfect way to ramp up the tension and make the reader sit up and wonder what's going to happen next.

Sellers delivers an engaging thriller with multiple storylines but they a re not complicated to follow. The police procedural at the centre of this storyline helps to provide depth and intrigue. I found this to be fast paced. I devoured it quickly.

The characters are well written. DI Anna Vaughn is a strong female lead but she is supported by a strong cast of characters, each bringing their own perspective and expertise to the investigation.

The plot itself is full of surprises and red herrings to keep the reader guessing. There are sub plots aplenty too, which i really enjoyed and helped to enhance the storylines and dynamics within the book.

This was a fabulous start to a new series. With sharp writing, a compelling lead, and a gorgeous Scottish setting, this novel really delivered everything you'd want from a mystery/police procedural without being too dark and heavy. I look forward to reading more in this series.

Thank you to NetGalley, Daniel Sellers, and Boldwood Books for providing me with a copy of this ahead of publication day in exchange for an honest review. My opinions are my own.

4* Good red herrings in a tale with multiple characters, any number of which could've killed the awful Ellen.

Ellen seems to be a very twisted Hyacinth Bucket-type character; keeping tabs on everyone and their - in her eyes, misdemeanours - making threats; interfering in their business; reporting them; spreading rumours and more. We don't fully learn what motivates her, as she's killed in the first few pages. She seems to have been a half-decent sleuth, with a very unchristian heart, sadly. Did she deserve her ending? For most of the tale I thought she did, but when the killer was revealed, perhaps Ellen had been trying to do a form of...not quite good, maybe, but the right thing? I mean, she'd have still had an ego boost out of it had she succeeded in unmasking the killer, but some people got the closure they needed after far too many years.

The characters in this were decent as was most of the police work. I'm not sure that some of the police should've been on the case given their connections with Ellen, but they did offer decent insight and knowledge. Pretty much every character potentially had been wronged by Ellen, who seemed to have some kind of personality disorder but also a massive superiority complex and arrogance to match. She never had a kind word for anyone, never seemed to enjoy small-village life, just liked to watch, snoop, make notes and keep a revenge diary.

The killer was twisted and their motivation about past actions wasn't revealed, although it's clear why they went after Ellen. I suspect there was a 'by proxy' element to their mindset, on top of what felt like enjoyment, too. They were worse than Ellen, for sure, but I'm not sure how they got away with things for so long, especially when people had spoken up.

In the end, I was about 80% sold on the killer, but how their nearest and dearest hadn't had the moral courage to do the right thing, was a tad unbelievable. Unless, they were about to when said killer did something unforgiveable...?

I always enjoy crime fiction, especially when it is set in Scotland, so was happy to have the opportunity to review the first book of the Scottish Highland Killings series.

I felt this was a very promising introduction to the series, and I particularly took a liking to DI Anna Vaughan. Anna is sent to investigate the murder of Ellen McIver, a local busybody who is very unpopular with her neighbours, and is run over repeatedly by a tractor on a remote road by the sea. There were certainly plenty of suspects who had a motive to kill her due to her pernicious actions in the community.

Alongside this events are happening at home for Anna where Anna’s mother in law is staying, and isn’t particularly wanted or nice to Anna, and a storyline develops with this.

It felt a while to feel really into the book, but that is really to be expected with a new series as the author introduces you to the main detective and sets the scene. For those who are a fan of Daniel Sellers’ other series, there is a brief cameo appearance by Lola Harris. Once the book really got going I found myself increasingly hooked and had to keep on reading, and I like how the author gave you a chance to work out the killer, which unfortunately some authors don’t.

I felt the book was well paced, had a range of interesting characters in, and some great dialogue in (which I always feel makes for a good crime detection book). I feel I have found a new detective and series for the future.

Overall I really enjoyed the book and eagerly await the next book in the series, and happily recommend this book to anyone who enjoys good detective and police procedural books.This would also be a good read for anyone who enjoys books set in the remote parts of Scotland, which is almost like another character in the book.

As an aside it’s always great to see a map at the front of a book - a nice touch here!

Thanks to Net Galley, the publishers and the author for providing me with an advance copy of the book, and I am happy to voluntarily leave an open and honest review of the book.

The Knapdale Murders by Daniel Sellers is a gripping and atmospheric crime novel that delivers a satisfying blend of procedural detail, strong characterization, and steadily building tension.

What stood out immediately was the setting. Sellers brings Knapdale to life in a way that feels vivid and immersive, and the isolated atmosphere adds an extra layer of unease to the investigation. The sense that everyone might be hiding something made the mystery feel more complex and engaging, and it created that classic small-community tension where secrets don’t stay buried forever.

The investigative elements were particularly well done. I appreciated how methodical and realistic the process felt, with clues revealed gradually rather than through convenient breakthroughs. The detective was a compelling lead—intelligent but human, carrying their own emotional weight while trying to remain objective. Their persistence and attention to detail made the case feel believable and grounded.

The pacing is more of a slow burn at first, focusing on establishing characters and motives, but it builds momentum as the story progresses. Once the pieces started coming together, I found myself fully invested and eager to see how everything would connect. The twists weren’t overly dramatic, but they were thoughtful and made sense within the story.

The writing style is straightforward yet effective, allowing the tension and emotional stakes to take center stage. Sellers does a great job balancing the mystery itself with the personal impact of the crimes, which added depth beyond just solving the case.

Overall, The Knapdale Murders is a solid and engaging crime novel with a strong sense of place and a well-crafted mystery. It’s an excellent choice for readers who enjoy atmospheric police procedurals and character-driven investigations with a steady, satisfying payoff.

DI Anna Vaughan was grateful to be called to Knapdale, on the Argyll coast. It took her from Glasgow and her mother-in-law who'd dropped in on them unexpectedly, and wouldn't leave. The small town of Baldrishaig wasn't far from where she and Neil had a small cottage, so Anna wouldn't have to worry about accommodation. But the death was quite obviously murder, and extremely gruesome. The woman, Ellen McIver, was disliked across the whole village, but someone had taken it to the extreme, using a tractor to repeatedly run over Ellen.

Jo McLean, the local DC, helped Anna in all they needed to do. It was a first for them both, but they were up to the task. The beauty of the Scottish Highlands, the small beach not far from the murder scene, the locals who held secrets, and also a dose of fear - would Anna & Jo get the answers they needed; discover the murderer before others died?

The Knapdale Murders is the 1st in The Scottish Highland Killings, and my first by Daniel Sellers and it definitely won't be my last! I thoroughly enjoyed the mystery; the strength of the two women who were leading the case, and the awe-inspiring beauty of Scotland's Highlands. I find I'm loving Scottish crime, after reading Neil Lancaster's gritty DS Max Craigie series, and now I have more to look forward to :) Highly recommended.

With thanks to NetGalley & Boldwood Books for my digital ARC to read and review.

The Knapdale Murders is a strong and really enjoyable opener to Daniel Sellers’ new Scottish crime series. It has everything I love in a rural‑set mystery — a close‑knit community full of secrets, an isolated landscape that adds to the tension, and a detective who feels both capable and wonderfully human.

DI Anna Vaughan is a great lead. She’s smart, dry‑humoured, and more than ready for a break from her stressful Glasgow life (especially the mother‑in‑law…), so the call to a remote murder in Knapdale seems like a welcome change. But the moment she arrives at the scene — a local busybody run over multiple times by a tractor — it’s clear this small village isn’t as peaceful as it looks.

I loved the partnership between Anna and local DC Jo McLean. There’s an easy rapport between them, and Jo’s knowledge of the area adds a nice balance to Anna’s outsider perspective. As they dig deeper, layers of tension in the community start to surface, and the sense of unease builds really nicely.

The mystery is well paced, full of red herrings, and rooted in long‑buried secrets that give the story a satisfying depth. Sellers captures the atmosphere of rural Argyll beautifully — the wild landscape, the sense of isolation, and the way everyone knows everyone’s business, even when they pretend they don’t.

By the final reveal, I was fully invested in both the case and Anna as a character. This series has tons of potential, and I’m already looking forward to the next book.

A great pick for fans of Aline Templeton and Scottish‑set crime with plenty of grit but not too heavy on the darkness.

Thank you to NetGalley for the ARC of The Knapdale Murders by Daniel Sellers

This was an engaging and well-structured rural crime novel, and an excellent first introduction to Daniel Sellers’ work. Set in the close knit communities around Knapdale, the story centres on the discovery of a body run over by a tractor on a remote country road. This death of a local busybody that quickly exposes the undercurrents of grudges, old wounds and simmering tensions that have been quietly shaping village life for years.

What I most enjoyed was the attention to the rural setting and the psychology of small communities. The way minor slights, resentments and half-spoken rumours can grow into bitter bad blood feels very believable, and it adds a richly textured backdrop to the central mystery. The slow unravelling of motives, from long standing feuds to new arrivals disrupting the social order, helped to make the investigation go beyond the purely procedural.

The characters are well developed and feel authentic to the landscape. There’s a real sense of local pride, suspicion of outsiders and unspoken history that grounds the narrative. The local detective’s attempts to balance community expectations with a rigorous search for truth provide much of the novel’s emotional tension, and I liked how personal and professional stakes intersect throughout.

The pacing is steady and the atmosphere and gradual build of suspense kept me engaged. A satisfying mystery with strong sense of place, believable characters and enough twists to hold interest until the end. As the first in a new series, it definitely has me coming back for more.

‘The Knapdale Murders’ is the start of a new series from the pen of Daniel Sellers. I adored the Lola Harris series, and although this is still in that universe, the tone of this one is a bit lighter and cosy. You can pick up this story though as a new reader, but I highly recommend the rest of the books he has written.

DI Anna Vaughan is about to lead her first case as a DI. Ellen McIver has been found dead in the remote village of Baldrishaig. She was repeatedly run over by a tractor, and it was no accident! Anna is being helped by a local DC, Jo McLean, and they soon realises the whole village has a reason to kill Ellen!

This was a gripping read right from the start! From the slightly gruesome scenes with the tractor to the final revelation, the narrative was engaging and full of misdirections and hidden reveals. Along with the death, there were various subplots— the mystery that Ellen was trying to solve herself and the more personal story with Anna’s mother-in-law from hell! These were deftly woven into the narrative by the author and added some depth and lots more intrigue.

Anna and Jo have the makings of being a brilliant team. They balance out one another, with Anna being more reserved than the bubbly and talkative Jo. They were nuanced with personal aspects being interlaced with the case, which manages to make them more interesting characters to read.

The location itself was important, and Daniel managed to paint a vivid and detailed picture of rural, picturesque Scotland. The writing is superb, and the tension and pacing were excellent. I am looking forward to the next in the series!

Let me know if you pick this one up!

A Twisting and Compelling Start to a New Series

Daniel Sellers has once again proved what a talented crime writer he is with The Knapdale Murders. As the first book in a brand new series, it delivers everything you could hope for in a gripping detective story: an intriguing case, well-drawn characters, and plenty of twists to keep the reader guessing.

DI Anna Vaughan makes a strong and memorable debut. She is a believable and engaging lead, and her dynamic with the rest of the team works extremely well. Sellers also weaves in glimpses of her personal life, adding depth to her character without ever slowing the pace of the investigation. Fans of the Lola Harris series will also enjoy the brief interactions between Lola and Anna, which provide a welcome link between the two worlds.

The mystery itself starts out complex and slightly puzzling, but that only adds to the enjoyment as the investigation unfolds. Piece by piece, the clues begin to fall into place as Anna and Jo work tirelessly to untangle the truth. Just when I thought I might have worked things out, another twist appeared, sending the story in a completely new direction.

By the time everything came together, the conclusion was both satisfying and unexpectedly poignant. This is one of those books that makes it far too easy to say “just one more chapter” — and before you know it, the evening has disappeared.

A brilliant opening to what promises to be a thoroughly addictive new series. I’m already looking forward to the next instalment.

Thanks to Daniel and NetGalley for allowing me to read The Knapdale Murders prior to the publication date.
This is the 1st book in a new series, with the author using a character, D.I. Anna Vaughan, from the previous series.
It is an easy and engaging read.
Daniel has created a cast of interesting characters in the book, some local born and bred and others are incomers.
To date, Anna;s experience has mainly been in the urban environment of London and Glasgow where the forensic teams are within easy reach. The rural setting will see Anna relying on the services of the local officers and their knowledge to contain the scene overnight in a country lane.
Anna has been tholing the uninvited presence of her sharp tongued mother-in-law, Melinda.
In an attempt to keep the peace, Anna’s husband, Nick, has taken them to an upmarket restaurant.
However Melinda immediately orders and demolishes an expensive bottle of wine, whilst loudly criticising everything and everyone.
Anna is relieved to receive the call to attend a suspicious death ( I suspect that she might otherwise have committed murder).
The victim, Ellen McIver, has taken an unofficial neighbour watch role, spying on the residents and documenting their perceived misdemeanours in her little black book.
Whilst farmer, old Wullie Cameron, is the likely culprit, details of Ellen’s behaviour are gradually revealed and the suspect list grows.

This was such an enjoyable start to a brand new Scottish crime series, introducing DI Anna Vaughan and I’m already looking forward to seeing where her story goes next.

Anna has recently been promoted and is sent to investigate a suspicious death in the remote coastal community of Knapdale in Argyll. What initially appears to be a tragic accident quickly reveals itself to be something far more sinister, and as Anna begins to dig deeper, it becomes clear that this small, tight-knit village is full of secrets.

I really liked Anna as a main character. She’s strong and capable but also very human, juggling the pressures of her new role alongside personal challenges, which added an emotional layer to the investigation. Her partnership with local DC Jo McLean worked well too, bringing balance and local insight to the case.

The rural Highland setting was a standout for me. Sellers creates that classic small-community atmosphere where everyone knows everyone and gossip spreads faster than facts. It gave the story a strong sense of place and helped build tension naturally as the investigation unfolded.

The plot itself is engaging, with multiple threads and suspects woven together without becoming confusing. There are plenty of red herrings and surprises along the way, and the pacing kept me turning the pages.

Overall, this is a solid 4⭐ crime read. An intriguing mystery, a compelling new lead character, and a promising start to what looks like a great new series.

Newly promoted Glasgow DI, Anna Vaughan, is called out to the Argyle coast, to the little village of Knapdale - a beautiful tranquil place, where nothing much happens - until now that is!

An elderly woman, Ellen McIver, has been found dead after a tractor repeatedly ran over her. The tractor belongs to local farmer Glen Cameron. The most likely culprit is Old Wullie, Cameron’s elderly father, who, despite his dementia, still likes to drive the tractor about the lanes.

McIver wasn’t liked locally, she was such a busybody, a mean spirited woman who liked to police her neighbours and cause unpleasant scenes for all and sundry.

When Anna arrives at the crime scene she’s certain that this wasn’t an accident. Someone definitely wanted McIver dead. With the help of local DC, Jo McLean, Anna begins her first ever murder investigation.

Beneath its beautiful facade, the peaceful village of Knapdale is not only hiding a murderer, but a whole host of secrets just waiting to be discovered!

This is a great start to this new Scottish crime series. Anna is a smart and feisty protagonist, and with more red herrings than you can shake a fishing rod at, it kept this reader engaged throughout!

Another fantastic and compelling read from Sellers so much so, he is now an auto buy author.
Not only can he write amazing gritty crime books but rural crime/police procedural stories too.
I absolutely loved this. You are instantly drawn in by the prologue. What was Ellen doing? What did she take from the outhouse and why was she killed in such a gruesome way?
I also enjoyed the opening chapter where we meet our protagonist DI Anna Vaughan, her husband Nick, and her monster, sorry mother in law, Melinda. lol It’s an hilarious chapter and I loved how Nick dealt with her and defended his wife. Green flags all round for Nick! 🥰

I enjoyed how the story developed throughout the chapters, constantly learning new things that turns what you thought you knew on its head. Providing twists and turns that add to intrigue without being overly complicated to the point you get lost.
There is also a fabulous array of characters that you’ll love, question and distrust in equal measures.
I normally come up with my own theories when reading crime/thrillers but, with this, I was too enthralled in the constant drama and revelations that I just kept turning the page desperate to know what happened next.

I truly was hooked and cannot wait to read more from DI Anna Vaughan. An amazing start to a new series.

Daniel Sellers is no stranger to writing mystery/thrillers and creating series around the main characters. “The Knapdale Murders” is the start of a new series by Mr. Sellers. This series stars DI Anna Vaughan. And what a protagonist she is!

I had seen Daniel Sellers’ novels from time to time. They have popped up as suggested reading on many occasions. But to be honest, I wasn’t looking for a new writer or series to dive into. But when I read up the blurb on this novel, I thought, “Why not.” I am so glad I did.

The characters are so richly written. The procedural is engaging and never boring. They mystery will keep you guessing right up till the big reveal. I even had to go back and reread the prologue after finishing the book. And to be honest, I started to go through the book again. There are very few authors that can grab my attention that much.

Now I have to deal with the fact that when I didn’t heed the advice and check out Daniel Sellers in the past, I was the one that missed out. He is one of the best writers in the mystery/thriller genre. So do yourself a favor and don’t miss out on this. People will be talking about this book and the series to come.

This was a strong, well-plotted Scottish police procedural set against the atmospheric backdrop of the Highlands and I loved every minute of it.

DI Anna Vaughan is already dealing with a tricky family situation in Glasgow when she’s called to oversee her first murder case in Baldrishaig. The local busybody has been killed in what looks like a tractor accident but it quickly becomes clear it’s anything but.

Trouble escalates back in Glasgow when Anna’s mother-in-law disappears, adding a compelling personal thread that raises the stakes even further.

The Highlands setting adds so much tension, with a close-knit community where everyone seems to know or is hiding something. One of the standout aspects for me was the presence of two strong female leads. DI Anna Vaughan and DC Jo McLean make a fantastic investigative team. Anna’s steady leadership combined with Jo’s local knowledge and sharp instincts gave the investigation real depth and credibility.

With personal drama brewing back home and secrets unravelling in Baldrishaig, this was a very solid police procedural with strong characters, an atmospheric setting, and a well-developed investigation. I’m definitely looking forward to seeing where the next instalment takes Anna.

The Knapdale Murders by Daniel Sellers was a really enjoyable cozy-leaning mystery with a classic small-town setup done well.

The victim is the village’s notorious busybody — always watching, judging, and threatening to report her neighbors for every perceived wrongdoing. So when her body is discovered, it quickly becomes clear that almost everyone had a motive. As the investigation unfolds, the suspect list keeps growing, making it frustrating (in a good way!) to sort through what actually matters versus what’s just local resentment and gossip.

I really loved the characters and the sense of community — even with all its secrets. The dynamics between the investigators and the villagers were engaging and kept me invested throughout. I did find the side plot involving Nick’s mother a bit distracting at times, as it pulled focus away from the central mystery, but it didn’t take away from my overall enjoyment.

This was a completely satisfying read, and I’d happily continue with this series. I’m definitely looking forward to reading more by this author.

The Knapdale Murders by Daniel Sellers is the first book in a new The Scottish Highland Killings series and I enjoyed reading this book. It was full of good twists and turns from the very beginning which made it a good turner. I enjoyed learning about DI Anna Vaughan, who is newly promoted and she is called to first case! in the remote Knapdale, on the Argyll coast. Now, she welcomes the chance to escape her life in Glasgow and more important the mother-in-law from hell.

Ellen McIver, is Baldrishaig’s local busybody, has been found dead. She has been Run over repeatedly by a tractor which belongs to local farmer Glen MacGibbon. who is the most likely culprit is Old Wullie. Now, Glenn MacGibbon’s elderly father, who, despite his dementia, and he still likes to drive the tractor about the lanes. and he feels nothing is wrong with him!!!
Now at the crime scene Anna can tell something sinister is afoot. . . . . this was no accident. Whoever drove that tractor did so with murder in mind. But Who?

This book was so good I ended up reading it all day and loved the new DI Anna Vaughan and now looking forward to the next book within this series.

The Scottish Highland Killings #1

When newly promoted DI Anna Vaughan is called to a case in remote Knapdale, on the Argyl coast, she welcomes the chance to escape her life in Glasgow - more specifically the mother-in-law from hell.... Ellen McIver, Baldrishaig's local busybody, has been found dead. Run over - repeatedly - by a tractor belonging to local farmer Glen Cameron. The most likely culprit is Old Wullie, Cameron's elderly father, who despite his dementia, still likes to drive the tractor about the lanes. But once at the crime scene, Anna can tell something sinister is afoot.... this was no accident. Whoever drove that tractor did it with murder in mind.

This is a multilayered story. Knapdale is a tight rural village where gossip can spread like wild fire. The pace is fast in this quick read. DI Anna Vaughan is a strong character and I liked her. There were twists, red herrings and surprises along the way. This is a promising start to a new series.

My thanks to NetGalley and Boldwood Books, for letting me read and review an advanced copy of ‘The Knapdale Murders’, by Daniel Sellers.

In this new mystery series by Sellers, DI Anna Vaughan is called out to the scene of a suspicious death in the Scottish highlands. Ellen McIver, the local busybody and village pest, was run over by a tractor (several times). DI Vaughan and local DC Jo McLean have to sift through several possible suspects, before they eventually get closer to a suspect with a real motive. At the same time, Anna’s husband is dealing with his mother, who evidently has gotten into trouble in London, causing Anna some distraction.

I really enjoy the Scottish setting for this mystery, as well as the storyline. Anna and Jo’s determination to solve the original case, as well as an additional murder, leads them to the reason why Ellen was the first victim and the secrets she had uncovered. This was a very nice cozy mystery/police procedural that kept my interest throughout.

As a lover of Daniel Seller’s ‘The Lollipop Man’, I was excited to read this new release by the author. This is Book 1 in a new series set in the Scottish Highlands when new DI Anna Vaughan is tasked with coming to a community town to solve a disturbing murder. I will be straight and say that I read this in a day. I found this easy to read and easy follow and at less than 300 pages, it was an enjoyable read. The reason it doesn’t hit full marks is definitely down to personal preferences. I found the chapters slightly too long at times (like I said, personal taste) but none the less they were easy to follow. I found the title of the book was a little confusing until around 70% but it did all tie up nicely towards the end and did make sense. It has several gasp moments which I obviously enjoyed and I did enjoy getting to know new characters as well as a little reference to the Lola Harris series. I am excited to see what book 2 holds and will definitely pick it up. This is for the mystery thriller lovers, new to thrillers and general quick readers and this is a nice rainy day read!

✨️Spoiler Free Review✨️

Thanks to @netgalley @danielsellersauthor & @theboldbookclub for the ARC in return for my honest review.

This was a cosy but gripping police procedural thriller that kept me guessing from start to finish and all set up in the Scottish Highlands where everyone knows everything about each other. The main character, DI Anna Vaughan, was great; really smart & intelligent, completely relatable and had a really good rapport with her colleague Jo, who is the local detective.
It was a proper 'whoduunit' type of book. It wasn't high octane excitement but it was very down to earth. There was a subplot also running alongside it, but for me it wasn't really needed. My only real criticism is that I felt that the ending was a not rushed but on the whole I did enjoy the book and will definitely read more!

A cosy mystery/police procedural story. Anna is having a tough time with her monster-in-law but seems to catch a break when her boss needs her to go to Knapdale to investigate a murder.

The monster-in-law is an absolute pain and there's a side story around her bad behaviour that is somewhat amusing. I can see it would be quite infuriating to deal with as a son and/or daughter-in-law.

The murder in Knapdale is a tricky one for Anna to unpick and you do wonder if her accommodation is likely to lead to some kind of mishap for her. The victim is also a bit of a pain with everyone having a reason to dislike her so it doesn't make things easy for the police. The culprit isn't obvious and it's much later in the story that you start to realise the real reason for the murder. Definitely a interesting twist and keeps up the suspense as you r as through.

In an isolated small town on the coast of Scotland, Ellen McIver is murdered, run over several times by a large tractor. DI Anna Vaughan is sent from Glasgow to investigate the killing. It seems the almost everyone in the village is a suspect as Ellen had logged all their possible, although imaginary, crimes into her always present notebook. She then reported them to any official who would listen. Anna, assisted by DC Jo McLean, painstakingly interviews each villager and has slowly narrowed down the list of suspects. Then there is another death.

The Knapdale Murders, by Daniel Sellers, is the first in a new series. An atmospheric location, captivating characters, an interesting subplot, a well planned plot - it’s an excellent police procedural. I’m looking forward to what comes next! 5 stars.

Thank you to NetGalley, Boldwood Books and Daniel Sellers for this ARC.

This is my first book by this author and I'll definitely be working through his backlist! This is my kind of crime thriller. Not too gritty, but very intriguing with a host of suspects in a small community. I loved how we got to know everyone and all the reasons behind animosity. I also loved that our main character, a newly promoted detective inspector was a normal functioning human being, in a positive relationship. How refreshing! A love a puzzle to solve and this book provided that. A knotty mystery, with prickly suspects and a murder victim who nobody liked. I enjoyed finding out the why out of it as much as the who. Cleverly written, an absorbing read that I whizzed through in a couple of days. ready for the next one!

I’m giving this a 4.5 stars! ⭐⭐⭐⭐✨
​A massive thank you to NetGalley and Boldwood Books for the ARC! This was an absolutely engaging thriller that pulled me in from the very first page. If you love a mystery that keeps you guessing until the final reveal, this is a must-read.
​The characters are incredibly rich and well-written. I was especially impressed with the protagonist—they are a well-drawn lead with a genuinely interesting background that adds so much layers to the story. The pacing is spot-on, never letting the tension slip as the mystery unfolds. Truly a great thriller read!

I would like to thank Net Galley for an ARC in exchange for an honest review.

Just another police procedural - 3*

Don't get me wrong! I'm a huge fan of police procedurals and I did enjoy this. I did. This is not one of those reviews where you criticise the author for every tiny thing. It absolutely isn't.

I enjoyed this novel. I did. I liked it and it stole a few hours away from me and I enjoyed it but did I love it? No. I didn't love it and that's okay.

I liked the characters but they're not memorable.
I liked the plot but I'm not going to think about it after I've read this book.
The subplot was there and I just have no feelings about that.

If you want a good police procedural, then this is the book for you.

A Stunning Start To A New Series! ​
Daniel Sellers’ latest series is a true gift.
Set against the atmospheric backdrop of rural Argyll and Bute, the vivid descriptions transport you straight to the rugged coastline. When unpopular villager Ellen McIver meets a brutal end via a farm tractor, newly promoted DI Anna flees a nightmare visit from her mother-in-law to lead the investigation. ​
The pacing is perfect, the characters are richly drawn, and the nod to Lola Harris is a treat for long-time fans. With layers as deep as the local waters and a conclusion tied up neatly as a gift-wrapped jar of homemade jam, this is a must-read.
I can't wait for Anna's next adventure and hope to see more of Jo!
My thanks to Netgalley and Boldwood Books for an advanced copy. This is my own opinion.

Recently promoted DI Anna Vaughn is sent to the remote community of Knapdale to investigate the death of Ellen McIver. Teaming up with local DC Jo McLean, she learns Ellen McIver was widely disliked, leading to a large number of suspects. As the investigation continues, it is learned that Ellen was carrying on her own investigation regarding a killer who has gone unnoticed. As Anna uncovers what Ellen was researching at the library, she realizes who the killer is. Multiple storylines keeps the reader turning the pages for the identity of the killer. Strong police procedural - looking forward to reading the next book.

This is the first book by Daniel Sellers that I have read - and it is the first of a new series. Lucky me!!
Also, I love a Police Procedural with a strong female lead, and DI Anna Vaughan is exactly that.
She is smart, and experienced in her investigations.
Also good is that her personal life is also mentioned - which is a must for me - as the police officers do have a life away from the station! It gives the story a 'real feel'.

I really enjoyed the novel, and raced through it, and finished it in under 24 hours.
I am looking forward to the next Anna Vaughan book, and will definitely look out for more Daniel Sellers books!

5/5 stars from me. I am hooked!
