Living and working in Snowdonia was always retired detective Frank Marshal’s dream. Until a phone call asking for his help turns it into his worst nightmare.
Retired detective Frank Marshal lives in a remote part of Snowdonia with his wife Rachel who is suffering from dementia. Working as a park ranger, Frank gets a phone call from close friend Annie, a retired judge. Her sister Meg has gone missing from a local caravan park and she needs his help to find her.
As Frank and Annie start to unravel the dark secrets of Meg’s life, it seems at first that her disappearance might be linked to her nephew and a drug deal gone wrong. In a shocking twist, their investigation leads them to a series of murders in North Wales from the 1990s and a possible miscarriage of justice.
Can Frank and Annie uncover the sinister truth so they find her sister in time to save her? Or will a brutal serial killer add Meg to his list of victims?
I love Snowdonia and have visited at least once a year since I was a child, even now staying in or close to the farmhouse we’ve booked since I was 12 years old. I also enjoy crime fiction so I can’t believe I haven’t come across Simon McCleave before. This is the start of a new series so I have the joy of going straight to the beginning of his other novels and devouring them. Frank Marshal is an interesting man, the ex-detective and mountain ranger lives in Snowdonia with wife Rachel who has dementia. For most of the novel their daughter Caitlin lives in the annexe with her son after fleeing an abusive relationship. It was quite a slow start to the novel but I could see what the writer was doing, setting the scene of the awe-inspiring landscape and also sowing seeds for future novels. I could see family issues and heartbreaking choices ahead for Frank, as well as some future rivals in the force and the criminal world. Annie was an interesting character too, an ex-judge and described as a close friend of Frank’s, he definitely shows his commitment and loyalty to that friendship as he puts himself in danger to find her sister Meghan. In a lot of ways Frank reminded me of my own father who has spent his life climbing all over Welsh mountains as a youth worker and climbing instructor. Frank’s desire to protect his family, as well as forgetting his age in the process was very familiar to me. Thank goodness my dad doesn’t have his guns anymore, but he’s not afraid to put his bare knuckle fighting and boxing skills to use when necessary. He’s a real worry. So I could imagine being Frank’s daughter and I recognised his determination when he realises half way through a fight that he’s feeling almost all of his 71 years.
The story really picks up speed after the first few chapters and as it became more addictive, I admit I stayed up until 1am this morning to finish. I had a hunch and I had to see how it played out. Frank and Annie’s investigation starts as Meghan goes missing and her son Callum turns up in hospital with amnesia. Annie doesn’t want to think that her nephew has anything to do with this, but at first they make a couple of discoveries that seem to point in his direction. However there are other potential avenues. The murky world of a 1990s serial killer, convicted when Frank was still on the force and a drug boss who dresses like a Boden model but is a Scouse gangster underneath. Frank’s police connections get them places most people couldn’t, including visiting a serial killer. They have a couple of nasty skirmishes too and I had to keep reminding myself that this was a couple of OAPs! Annie is equally ballsy and has some connections of her own, including a youth offender who now works in IT so he can care for his elderly mum. I’m fascinated with cold cases, in terms of the science we now use to convict offenders decades later, but also because of the things that are missed and dismissed. There’s a detail that’s so important to finding the truth that was completely dismissed by officers due to the witness being a sex worker. I watched a documentary about the Yorkshire Ripper where the police’s attitude to first killings was almost a shrug of the shoulders because they were sex workers. Yet when he killed a young woman on her way home after a night out both police and press said it was his first ‘innocent’ victim which made my blood boil. Frank and Annie find the witness, who has two very pertinent clues ignored for thirty years that could be the key to the case.
I’m always complaining about thrillers and crime novels that rely on their twists and turns without any depth to the characters or the story. I couldn’t complain at all here. There are twists, including one I only started to suspect few pages before it was revealed. However, the book was also full of emotion: Frank and his wife sitting in bed and looking at old photos was so poignant since both know she is slowly forgetting it all; the beautiful relationship between Frank and his grandson; Annie’s grief over her sister’s disappearance and her nephew’s accident. All felt like fully realised people, even those only in the novel a short time. I could see Frank locking horns with police chief Dewi in the future. I felt totally creeped out by Meghan’s rather unsettling neighbour at the caravan park. I was even interested in the scouse drug dealers and could imagine them finding their way into future storylines. I loved the setting too, the author has managed to capture it’s beauty and it’s bleakness, plus I look forward to visiting the Barmouth chippy when I go there later this year. This was a cracking mystery that crept up on you slowly then didn’t let you put it down. I’m looking forward to many more adventures with Frank Marshal.
