Evan Help Us, by Rhys Bowen, is a Constable Evan Evans mystery.
The novel takes place in the village of Llanfair, Wales where Evans is stationed. It is a "policeman as detective" story, rather than a police procedural.
Here's the description from Amazon:
In the ineffably quaint and impossibly charming village of Llanfair in North Wales, Evan Evans is into his second year as local constable: his landlady spoils him, the buxom barmaid flirts with him, and the golden-haired schoolteacher with the cornflower-blue eyes helps clear his mind but muddles his heart. Two murders in quick succession stun the town: an elderly retired colonel whom everyone liked and a returning local, who announces plans for a haunted slate-mine theme park (!) just before being dispatched. Evans-the-Law (to distinguish him from Evans-the-Meat, the butcher, and Evans-the-Milk, the dairyman) is sure there is a connection, and it may have to do with the colonel's discovery of some possibly ancient ruins or the strong feelings that run for and against the tourists that Morgan's plans would bring to Llanfair.
While the book is well-written, I'm afraid I couldn't get into the character of Evan Evans, in particular because of the love triangle. He's in love with a woman named Bronwen, but is too shy to make his feelings known, and vice versa. And one of the susupects is a beatiful woman...
