Thanks all... we really enjoy this program but, unfortunately here in the U.S., it moves around from channel to channel. We used to get it on Hallmark, but now it's on Biography at 1300 hours on Saturday for crying out loud! We're not much for TV, but this one is a keeper, as they say.
For one thing, one has to pay close attention to keep track of all the various characters that are introduced and, more especially, to these tin Yank ears, one has to listen closely to decipher the dialogue from the sometimes intense accents. (For such a seemingly small county the murder rate is atrocious!)
One aspect that is greatly appreciated is alluded to by spudqueen, that being small inferences that could easily be missed. Another is that sometimes the overall tone of one program is dark and foreboding only to be followed by one that is semi-humorous (at least as humorous as murder can be). I've also noted that recurring background noises are utilized for dramatic effect. In every program there's an unseen barking dog and a shrill bird call (usually a crow). Mrs. C thought I was imagining it until she began paying attention...
At any rate, thank you for your answers and thanks to the British for this understated drama, from this side of the Atlantic...
