🔥 BBC’s ‘Twisty’ New Welsh Crime Thriller Featuring a Shetland Star Is Already Turning Heads — The Dark 6-Part Coastal Murder Mystery About an Unlikely Detective Duo Sounds Like the Next Addictive Binge for Crime Drama Fans!!
Crime drama fans, brace yourselves — the BBC has just unleashed a fresh Welsh gem that’s poised to become your next obsession. Packed with jaw-dropping twists, dark secrets, stunning coastal backdrops, and an unlikely detective partnership that crackles with chemistry, Old Town Murders is already generating massive buzz ahead of its release.
This six-part thriller follows two seasoned detectives — old friends reunited by circumstance — as they tackle baffling murders in the picturesque seaside town of Tenby, southwest Wales. Think Midsomer Murders meets Shetland with a hearty dose of Welsh heart and wit. If you loved Grantchester, Under the Salt Marsh, or the brooding intensity of The Shetland series, this one’s going straight to the top of your watchlist.
From Bereavement to Breakthrough: The Heart of Old Town Murders
The story kicks off when DI Glyn Walsh (Mark Lewis Jones) returns early from bereavement leave, only to be thrust into partnership with DS Sion Dearden (Steffan Rhodri). What starts as a complex investigation into the murder of an esteemed university professor quickly spirals into a web of university intrigue, local secrets, and multiple baffling killings across the region.
One victim is a local head teacher mysteriously poisoned and found drowned while wild swimming. Another involves a shocking case of mistaken identity during a triathlon. The duo must navigate these perplexing cases while literally living under the same roof, blending sharp procedural work with deeply personal stories of reinvention and friendship in later life.
Set against the breathtaking modern-day Tenby coastline — with its colourful harbour, dramatic cliffs, and sweeping South Wales landscapes — the series promises visuals as compelling as the crimes. Creator Matthew Barry describes it as more than a crime drama: “At its heart, it’s about friendship, reinvention and the courage to begin again later in life.”
Star Power: Mark Lewis Jones and Steffan Rhodri Lead the Charge
Leading the cast are two powerhouse Welsh actors with serious pedigree. Mark Lewis Jones, known for standout roles in Baby Reindeer, The Crown, Men Up, and gritty dramas like Out There, brings his trademark intensity to DI Glyn Walsh. His portrayal of a detective grappling with personal loss while hunting killers is already being tipped for awards buzz.
Steffan Rhodri, beloved for Gavin & Stacey, Steeltown Murders, and Men Up, steps into DS Sion Dearden. The pair’s real-life friendship and previous on-screen collaboration in Men Up translate into authentic, lived-in chemistry that elevates every scene. Their banter, shared history, and mutual support amid chaos make them one of the most watchable detective duos in recent British TV.
The supporting cast is equally impressive. Julie Graham (This City is Ours, Time) plays forensic biologist Pamela Thomas, bringing sharp scientific insight to the investigations. Catherine Ayers (The Guest, Missing You) appears as Chief Superintendent Melanie Morris, while Bethan Mary-James and James Bamford round out the team as DC Remy Jones and DC Neil Miller.
This ensemble promises rich character dynamics, with personal stakes that run as deep as the mysteries themselves.
Twisty Plots, Coastal Charm, and Dark Underbelly
What sets Old Town Murders apart is its perfect blend of cosy coastal charm and chilling crime. Tenby’s idyllic harbours and beaches hide a seedy underbelly of university scandals, small-town grudges, and shocking betrayals. Each episode delivers a self-contained case while advancing a larger arc of friendship and purpose.
Expect poisoning plots, identity swaps, academic corruption, and plenty of red herrings. The series explores how these later-in-life detectives find renewed meaning through their work and bond — a refreshing take that resonates far beyond typical whodunits.
The Welsh locations steal the show too. From Cardiff’s urban edges to Tenby’s stunning coastline and historic sites, the scenery adds atmosphere and authenticity. Viewers will feel transported to these windswept shores as the body count rises.
Why This Series Is Poised to Explode
In a crowded TV market, Old Town Murders stands out with its witty script, heartfelt themes, and star chemistry. Produced by Quay Street Productions (behind hits like Fool Me Once and After the Flood) and created by Matthew Barry, it has pedigree to match its promise.
BBC Cymru Wales Head of Commissioning Nick Andrews called it “where picture-perfect Wales meets murder mystery in a thrilling, twisty tale.” Early read-through photos and announcements have fans of British crime dramas buzzing on social media, with many comparing it favourably to Shetland for its sense of place and character depth.
For fans tired of bleak Scandi-noir or overly slick US procedurals, this offers warmth, humour, and emotional grounding alongside the twists. It’s the kind of show you’ll binge in a weekend, then immediately rewatch for missed clues.
The Bigger Picture: Friendship, Hope, and Second Acts
Beyond the murders, Old Town Murders delivers a poignant message about finding purpose later in life. As Glyn and Sion confront their own demons while pursuing justice, the series celebrates resilience, male friendship, and the idea that it’s never too late for reinvention.
This thematic depth, combined with clever plotting and stunning production values, positions it as more than just another detective show — it’s a character-driven drama with universal appeal.
Don’t Miss This Welsh Wonder
As filming wraps and anticipation builds, Old Town Murders is shaping up to be the BBC’s next big crime hit. With its irresistible mix of twists, talent, and terrific locations, it’s tailor-made for crime drama devotees seeking their next addictive fix.
Mark your calendars and prepare for late nights glued to the screen. In the sleepy seaside town of Tenby, murder is anything but quiet — and the detectives bringing killers to justice are about to win your heart.
