CASES
A detective who never quite leaves the coast
Every case in this series is investigated by the same small team, on the same stretch of North Wales coastline — read one book and you already know them.
DCI Trevor Llywelyn
Twenty-three years on the job, all of it within sight of this coast. Walks two collies, Bracken and Nel, every morning whether there’s a case on or not — and more often than he’d like to admit, one of them finds the first piece of evidence before he does. Divorced from Alys, settling slowly into something real with Megan, and still carrying, five years on, the pen that belonged to the mentor he couldn’t save in time.
Rhian
Trevor’s detective sergeant — meticulous, unflappable, the one who builds the case file while everyone else is still reacting to the body.
Bethan
Steady where the job needs steadiness most — the colleague Trevor calls first when a discovery is about to get personal.
Dylan
The unit’s youngest — forums, phone records, the digital trail nobody else on the team has the patience for.
Eleri Vaughan
Trevor’s superintendent for most of the series — sharp, protective of her officers, and edging closer to a retirement that changes everything about how the unit runs.
Calvin Arwyn Hughes
Trevor’s mentor. Missing, presumed dead, since long before Book One — and the case Trevor has spent five years not quite able to open.
The Llŷn Chronicles
Four novellas, one continuous story. Start with Book One — each one picks up threads the last left dangling, building to an answer Trevor’s been avoiding for five years.
The Smuggler’s Tide
A boat sinks quietly at her own mooring in Pwllheli harbour — with a body aboard. What looks like an accident opens onto a smuggling operation that’s older than Trevor’s career, and the first real crack in the five-year-old silence around his mentor’s death.
The Saints’ Hoard
A volunteer surveying seabird burrows on Bardsey finds something in a sea cave that has no business being there. The trail leads Trevor into antiquities trafficking — and, for the first time, all the way to Chester.
The Apostles’ Wake
A diver surveying the century-old wreck of the Twelve Apostles off Porth Neigwl finds a second wreck nearby — one with modern hull plating, and a body that’s far too recent to belong to 1898.
The Keepers’ Reckoning
A storm uncovers new evidence in the exact gully where Calvin’s car went off the road five years ago. After half a decade of not asking, Trevor finally gets the case — and the reckoning — he’s been putting off.

The Llŷn Casebook
After Book Four, Trevor is promoted and stands up the North Wales Cold Case Review Unit. These two anthologies collect eight standalone cases from the new unit’s early files — no series arc required, read in any order.
Four Cases
- What the Tide Uncovers — a storm-buried find on Hell’s Mouth beach
- The Packet Port — a heritage society chairman, dead below the cliff path
- The Corpse Candle — an old superstition, twice witnessed on the pilgrim road
- Whisky Galore, Properly — a family “salvage” story that doesn’t add up
Four More Cases
- The Arrow Field — a detectorist found dead by a wartime ruin
- The Auction — a shipping container breaks up on the rocks, and a village helps itself
- The Cursed Village — a language-course student goes missing at Nant Gwrtheyrn
- The Private Island — a TV survival show, a lost access right, and an unlucky margin
