Evan Warlow Books in Order: The Complete Rhys Dylan Reading Guide
If you enjoy British police procedurals that combine difficult investigations with the character dynamics of a continuing detective series, Evan Warlow is worth exploring. The books are set in Wales, where dramatic landscapes and close-knit communities provide the backdrop for murders, disappearances, and long-buried secrets.
Warlow’s cases are individually resolved, so you can understand the central mystery in each book. However, his relationships with Jess Allanby and the wider police team develop over time. Reading the books in order gives you the fullest picture of those changes.
Evan Warlow Books in Publication Order
The following list covers all 21 main novels published through 2026, with a brief introduction to each mystery. Publication order is the recommended reading order.
1. The Engine House (2021)
The series begins when a landslip on Pembrokeshire’s coastal path exposes the remains of two bodies. The discovery brings former DCI Evan Warlow out of retirement because he originally investigated the disappearance of the two people years earlier.
As the investigation reopens, more deaths raise the stakes. Working with a younger team, Warlow must revisit the past and uncover what happened before the killer can conceal the truth again.
This is the essential starting point because it introduces Warlow, his investigative instincts, and the unresolved case that draws him back into police work.
2. Caution: Death at Work (2022)
A dark past casts a shadow over Warlow’s next investigation. The second novel continues the series’ focus on crimes that cannot be understood by examining the immediate evidence alone.
Warlow must look beyond the obvious explanation and work through the people, relationships, and history surrounding the case. Read it after The Engine House to continue following the detective’s developing story.
3. Ice Cold Malice (2022)
Revenge is at the heart of this third installment. The investigation draws Warlow into a case where past grievances and present-day consequences become difficult to separate.
The title captures the cold, deliberate quality of the mystery. As with the earlier novels, the investigation depends on understanding what people have done, what they want to hide, and how old resentments can turn dangerous.
4. Suffer the Dead (2022)
When a farmer and his son go missing while chasing something in the countryside, the disappearance sets the stage for another troubling investigation.
The rural setting plays an important part in the mystery, where an apparently ordinary disappearance can conceal a much more complicated story. This installment continues the series’ use of Welsh communities and landscapes as more than just scenery.
5. Gravely Concerned (2022)
The fifth novel explores a world in which predators are patient and danger may be closer than it first appears. Warlow must investigate the circumstances behind a case that raises questions about who is watching, who is vulnerable, and who may be preparing to strike.
It is another entry in the series’ blend of police investigation and psychological tension.
6. A Mark of Imperfection (2023)
Warlow has enemies, and his position as a detective chief inspector means that the work can bring him into conflict with people who have their own reasons for resisting an investigation.
The sixth novel continues to develop the pressures surrounding his professional life. It is best read in sequence because the wider series increasingly depends on the history and relationships established in earlier books.
7. Burnt Echo (2023)
A disturbing discovery involving a deep, dark hole and a foul smell leads into another investigation. The details point toward something concealed, and Warlow must establish what lies behind the discovery and how it connects to the people involved.
The novel uses the idea of something buried or hidden to build an unsettling crime story, while continuing the series’ focus on the secrets that communities would rather leave undisturbed.
8. A Body of Water (2023)
A delivery driver stumbles across a dead body, setting off a new investigation for Warlow and his team.
The discovery opens a case in which the circumstances surrounding the death are as important as the identity of the victim. The novel continues the series’ emphasis on careful police work and the gradual reconstruction of events.
9. Lines of Inquiry (2023)
The ninth book brings the investigation closer to the police themselves. Warlow suspects that a murder may involve one of their own, complicating the task of establishing the truth.
Cases that touch the police force can be especially difficult because professional loyalty and personal relationships may interfere with an objective investigation. This installment puts those tensions at the center of the story.
10. No One Near (2023)
The title suggests isolation, and the novel uses that sense of vulnerability to shape its crime story. Warlow faces another investigation in which the circumstances surrounding a victim and the absence of obvious help become important questions.
It is the tenth main novel and a natural point to appreciate how rapidly the series has expanded since its debut.
11. The Light Remains (2024)
A revered sports legend becomes central to a case involving the games people play and the public images they maintain.
The contrast between a celebrated reputation and the private realities behind it gives the investigation its central tension. Warlow must work through the relationships and hidden details that can turn an apparently straightforward case into something far more complicated.
12. A Matter of Evidence (2024)
The twelfth novel explores the consequences of wrongdoing and the difficulty of deciding what evidence truly proves. The case unfolds in a bleak setting, where the circumstances surrounding a crime demand careful scrutiny.
The title points to one of the central questions of police work: how investigators distinguish what they suspect from what they can actually establish.
13. The Last Throw (2024)
This case is described as more than personal, suggesting that the investigation reaches beyond a routine crime and into matters that carry a deeper emotional cost.
Warlow must navigate the facts of the case while confronting the personal stakes surrounding it. As the series progresses, professional responsibility and individual relationships continue to intersect.
14. Dragon’s Breath (2024)
Set against the mountains of Wales, this novel explores the dangerous secrets that can be hidden in remote places.
The landscape gives the story a strong sense of place, while the investigation requires Warlow to look beyond what is immediately visible. It is the fourteenth main novel and another example of the series’ use of the Welsh setting to create atmosphere and tension.
15. The Bowman (2025)
In the wild heart of Wales, terror stalks the open countryside. The investigation draws Warlow into a case where the rural landscape and the danger surrounding it are central to the story.
The fifteenth novel continues the series’ interest in the unsettling gap between picturesque scenery and the violence that can take place within it.
16. One Less Snake (2025)
This installment turns toward a seemingly sleepy coastal town, where the peaceful surface of local life hides a more troubling reality.
The title hints at the removal of a dangerous presence, but the investigation must establish who is involved and what has actually happened. The book continues the series’ exploration of small communities where personal history and hidden motives can be closely intertwined.
17. A Word with the Dead (2025)
A body in the hills, a missing man, and an unreliable account create the starting points for this investigation.
Warlow must determine which details can be trusted and how the different pieces of the case fit together. The novel’s premise makes it a natural choice for readers who enjoy mysteries built around conflicting accounts and uncertain evidence.
18. Druid’s Moor (2025)
The eighteenth novel returns to the atmospheric Welsh landscape, this time focusing on a moor where the dangers are not limited to the natural world.
The setting gives the story an unsettling edge, while the investigation explores the darker possibilities behind the events unfolding there. It is the final main-series release of 2025.
19. Cross Cut (2026)
The nineteenth novel opens with the idea that the dead are not necessarily the greatest source of trouble for Warlow. The living may be the more difficult problem.
The investigation brings fresh challenges for the detective and continues the series’ interest in the people who remain after a crime has occurred. It is part of the 2026 run of Evan Warlow novels.
20. Wilful Cruelty (2026)
A body, a silent street, and too many people who may have something to hide form the starting point for this crime story.
The case challenges Warlow to work out how the victim’s death connects to the people nearby. The title suggests deliberate harm rather than a simple accident, but the investigation must establish the facts rather than rely on appearances.
21. Reckless Deceit (2026)
The twenty-first main novel continues Warlow’s investigations with a case involving a murder of crows and an unsettling set of circumstances.
The story adds another mystery to the series’ growing collection of Welsh crime investigations. If you have followed the books from the beginning, this is the latest published main installment as of October 2026.
Where Does The Wolf Hunts Alone Fit?
The Wolf Hunts Alone is a free prequel novella associated with the DCI Evan Warlow series. It is available through Rhys Dylan’s official author website and is a useful extra for readers who want more of the series’ world.
You can read it before The Engine House if you prefer a prequel-first experience. Alternatively, start with the first full-length novel and return to the novella afterward.
For readers who want the simplest route through the series, the 21 main novels listed above are the priority. The prequel is an optional addition rather than a replacement for the opening novel.
Should You Read the Evan Warlow Books in Order?
Yes, publication order is the best approach, especially if you plan to read several books. Each novel has a main investigation, so the central crime generally reaches a resolution within that book. You do not need to remember every clue from the previous novel to understand the next case.
However, the continuing cast matters. Warlow’s working relationships, his connection with Jess Allanby, and the wider police team’s development carry across the series. Starting with The Engine House helps those details build naturally.
If you have already read a later book, you can still go back to the beginning without losing the enjoyment of the individual mysteries.
What Makes the DCI Evan Warlow Series Different?
The series is rooted in Wales, particularly the landscapes and communities of South Wales. Rural roads, coastal paths, mountains, and isolated settlements often become part of the atmosphere surrounding an investigation.
The books also focus on the gap between how a community appears and what its residents may be concealing. A murder or disappearance can expose old grudges, hidden relationships, and histories that have remained buried for years.
Warlow himself is another reason to read the series in sequence. His experience and observational skills shape the investigations, while the continuing relationships around him give the books a sense of progression beyond the individual crime.
