[1] The series stars Eve Myles as Faith Howells, a solicitor at a family-run law firm whose husband, Evan, disappears whilst she is on maternity leave following the birth of their third child.

[12] Set in the fictional town of Abercorran, filming started in the summer of 2017 in Carmarthenshire, with exterior views of Faith's home situated high up overlooking the estuary and the castle of Laugharne.

With a stellar cast and a completely compelling story, plot and setting, we're hoping the audience will grow to love the world and the characters of Un Bore Mercher as much as we in S4C have as we worked to develop the series.

[20] Gary Raymond, in Wales Arts Review, wrote: "...particularly interesting to see a genuine diamond emerge from the coalface in the form of Keeping Faith" and "Social media opinion has been a little more approving" [than the limited publicity surrounding the series].

[22] A review (under 'Show and Tell' by Paul Flynn) in Grazia magazine was titled "Like Broadchurch when it was good, Welsh production Keeping Faith is a TV trailblazer" and was generous with its praise.

[24] Jon Coates in the Daily Express wrote, "Keeping Faith's unprecedented success ... has led to a primetime run on BBC One starting on Thursday ... with a second series due to begin filming this autumn.

"[25] The Guardian review in July 2018, "... already a huge iPlayer hit, this Carmarthen-set drama about a vanished husband is realistic and beautifully shot ... it looks real and brilliant and Welsh".

[27] The first series won three Welsh BAFTAs in 2018: Best Actress (Eve Myles), Best Writer (Matthew Hall) and Original Music (Amy Wadge and Laurence Love Greed).
