Just finished Under Salt Marsh and enjoyed it a lot. The Guest with Eve Myles is another bit of Welsh fun. Not sure how available it is but I recently finished a two series drama called The Gone which is set in New Zealand and features an Irish link (an Irish detective teams up with a local Kiwi as a result of a young Irish couple going missing - why that comes about is plausibly explained). Beautifully shot, and Maori language and culture feature prominently. Its well worth a watch if it is available in your part of the world.
