Retired detective Frank Marshal lives in a remote part of Snowdonia with his wife Rachel who is suffering from dementia. When Frank and his grandson Sam witness a coach crash, the hero of the hour, a wealthy local landowner Ben Carver, seems desperate not to be in the spotlight and that seems suspicious.

Police are contacted by a woman claiming that the man she has seen on the news is not Ben Carver but her husband Daniel Owen who went missing several years earlier. Frank and his friend Annie, a retired Crown Court Judge, begin to investigate as they unravel the dark secrets of Ben Carver’s life.

Can Frank and Annie uncover the sinister truth behind the true identities of the two men who bear a more than uncanny resemblance to each other.


Marshal of Snowdonia is the fifth book in the Frank Marshal Crime Thriller series from multi-million bestselling author Simon McCleave. If you like dark thrillers, psychologically complex characters and shocking twists, then you’ll love Simon McCleave’s pulse-pounding new novel. Perfect for fans of LJ Ross, JM Dalgleish, Rachel McLean and JD Kirk.

Blood Mountain: A Frank Marshal Crime Thriller (Marshal of Snowdonia Book 5) Simon McCleave

A book written by Simon McCleave never fails to have you sitting and neglecting housework, dog walking and anything else you have to do. They are what it says in the title, Crime Thriller. I have read each book as they come on sale and every one is different but the same, I just can’t put it down!
Enjoyment on paper is what it is. I thoroughly encourage any book reader to try any of his books and you will become aware that I am right. Just read!!

Blood Mountain - a review by Rosemary Kenny.

Blood Mountain is set in North Wales, in a former slate-mining community that hides a long-buried secret about a local family. It's brought to light by chance after a coach crash. The phrase, 'no good deed goes unpunished' could have been coined for this, yet the reverse is also true in this case, as Frank Marshall and his sidekiclk Annie work to unravel a murder-mystery that is likely to be their strangest investigation yet.

Simon McCleave writes a gripping story with great characters and well-researched locations, which blend seamlessly into a fascinating whole.

This was such an addictive crime thriller and honestly one of those books that keeps you guessing the entire way through. Simon McCleave has a talent for creating suspense without rushing the story, and I found myself completely invested in the mystery surrounding Ben Carver and the missing man, Daniel Owen. Every time I thought I had figured things out, another twist came along and changed everything.

What really made this book stand out for me was Frank Marshal. He’s not your typical detective character, and that’s exactly why he feels so real. Seeing him deal with his wife Rachel’s dementia added a deeply emotional layer to the story that stayed with me throughout the book. Their relationship was heartbreaking at times but also incredibly touching, and it gave the novel much more depth than just being a standard crime thriller.

The setting in Snowdonia was another highlight. The atmosphere was brilliantly written — quiet, remote, and slightly haunting in a way that perfectly matched the mystery. I could almost picture the landscapes and feel the tension building in those isolated surroundings. It added so much mood to the story.

I also loved the partnership between Frank and Annie. Their investigation felt intelligent and believable, and the way the secrets slowly unraveled kept me hooked from beginning to end. The psychological side of the story was especially well done because nothing felt too obvious or predictable.

The pacing was excellent too. It balanced emotional moments, detective work, and suspense perfectly without dragging. By the final chapters, I genuinely could not stop reading because I needed to know the truth behind the identities of the two men.

If you enjoy crime thrillers with strong characters, emotional depth, atmospheric settings, and genuinely shocking twists, this book is absolutely worth picking up. Simon McCleave delivers a story that feels both gripping and emotionally human at the same time. Definitely one of the most memorable thrillers I’ve read recently.

I find this series a very quick read - the books are quite short and the plots relatively easy to suss out so they do not take too much concentration to complete. I like the characters and their development however I am not keen on the way Frank can basically do what he wants to do without any consideration to correct police proceedures, I mean he randomly has a tracking device that he can slip on a car on someone that feels "off" to him, whether he turns out to be a suspect or not 😱
Also I feel that if two elderly strangers randomly turn up on a doorstep wanting the third degree on the residents life story hmm would you just role your lifestory out to complete strangers, thats weird
As for the police chase, hmm like Franks car would be the fore runner in that and the police wouldn't let him and Annie get that close no matter how good he was back in the day and lets not forget the shotgun 🤦‍♀️
Just a bit far fetched procedurally for me to go any better than a 3 ⭐

Heart Stopping

Another grest story from Simon who has again delivered the goods. Apart from a miscalculation with date if birth if one character who was born in 1966 and described as being 63 in 2026, that was just human error. The story kept me guessing right to the final climax when nothing is quite what it seemed and people are the most complex and calculated individuals when their back is up agsinst the wall. Looking forward to the next Frank and Annie adventure in Nov 2026 when Simon assured me he WILL be back. Can't wait. Grown fond of this couple, mire soas they are nearer my age and nothing will hold us oldies back, unlike the young, we have a lifetime and weath of experience on our side. Never doto understimate us pensioners, we ARE full of surprises under the surface..

Excellent read

This is a very thoughtful book, with a few different strands that you follow throughout the story. Very clever plot and certainly unexpected. Quite emotional in parts, with very realistic descriptions of behaviour and reactions that I can really relate to with regard to dementia. Really enjoyed it and am looking forward to the next one.

The Best Yet

The history of Welsh slate mining. The disaster of 1904. Bullying of a young boy and abuse of another.
Then a bus crash with a real local hero.
Or is all not quite as it seems?
The pairing of Frank and Annie doesn't really strike me as being very likely but it makes for great reading.
I heartily recommend this book.

Another great read from Simon

As always a great read from this author. Everytime I finish one of his books I want to book a trip to Wales! There is always just the right amount of intrigue to keep you turning the pages and to keep you awake in to the early hours to read one more chapter!!!

Perfect!

This book was about so much more than a murder mystery. It spoke of the importance of friendship and family. And it also spoke about the love and loyalty of our dogs...both from them to us and us humans to them. I can't wait to read more from the author.

Another Compelling Read

MCleave has woven another compelling, engaging tale, set against the magical, otherworldly setting of North Wales. This may be one's of his most satisfying books to-date.

I usually love Simon’s books. Not this time. Entirely predictable from almost the beginning. It really felt like an overdone story line to meet a publishing deadline.
