Cleddau returns for second series on S4C and BBC iPlayer

The award-winning Welsh crime drama Cleddau is returning for a second series, set to launch on S4C this October. The English-language version, The One That Got Away, will also be available on BBC iPlayer, continuing the show's dual-language production format.

The six-part second series sees DI Ffion Lloyd (Elen Rhys) and DS Rick Sheldon (Richard Harrington) reunite to hunt a killer who uses a dating app to stalk and target victims. Newly released images showcase the Pembrokeshire coastline, which serves as a dramatic backdrop to the series.

Cast and crew

Returning cast members include Mali Ann Rees as DC 'Mogsy' Morgan, Aled Pugh as DS Celyn Howells, Sharon Morgan as Delyth Lloyd, William Thomas as Griff Lloyd, Rhian Blythe as Helen Sheldon, and Hannah Daniel as Lisa Redwood. Joining the cast for the second series are Saran Morgan as DC Catrin Duffy, Garmon Rhys as Tom Danbridge, Mabli Jên Eustace as Manon Grant, and Gareth David-Lloyd as Liam Floyd.

The series is written and created by Catherine Tregenna, adapted into Welsh by Hanna Jarman and Matthew Glyn Jones, and directed by Siôn Ifan.

Reception and accolades

The first series of Cleddau was a significant success for S4C in 2024, achieving the highest average viewing sessions of any non-sport and non-children's series on the service. It went on to win Best Drama at the RTS Cymru Wales Awards in 2025 and was nominated in four categories at the BAFTA Cymru Awards, including Elen Rhys for Best Actress.

Producer Mared Swain expressed delight at the response to the first series, saying: "We were delighted by the response to the first series of Cleddau, from audiences in Wales and beyond. The story, characters and world Catherine Tregenna created left us with so many possibilities to explore, so we're thrilled to be bringing viewers a second series." She added that returning to Pembrokeshire with the cast and crew had been a privilege, and expressed gratitude to S4C, particularly Gwenllian Gravelle, Head of Film and Drama, for continued support.

Viewer reactions

Audience feedback on the first series has been mixed. Some viewers praised the show, with one Rotten Tomatoes review stating: "We loved it. Binged the show." Another said: "I binge watched this after finding it on bbc iplayer. The story was interesting and was a fresh take on the serial killer crime genre." However, other reviews were more critical, with one noting: "Good watch, couple of occasions where police jump to conclusions slightly ruined it. Elen Rhys fantastic in lead role." Others offered harsher assessments, including "Good but extremely flawed procedurally" and "So predictable it was ridiculous."

What was claimed, and who backed it

Each row is one claim, attributed to the outlet whose wording states it most clearly. Confidence rates how directly the source text states the claim — explicit and unhedged rates high; hedged, pieced-together, or internally inconsistent statements rate lower. It does not measure whether the claim is true. Status counts the distinct outlets we found asserting it — so a single-source claim can still show high confidence, and a multi-source claim can show medium. Every one of those outlets is named beside the status, so you can check the count against the list. For claims extracted before we began storing that list, the row says so: it names the outlet the claim is quoted from and states that we have not recorded which outlets backed it. Outlets wrote at different times, so a figure that evolves — a casualty count, for example — can legitimately differ between rows; check the "as of" time next to each claim's source.
