I'm enjoying this series as well (currently airing in Australia). It is light and old-fashioned; can't believe it was made in 2015. I compare it to Murder in Suburbia or Rosemary & Thyme; light-hearted murder who-dunnit, put your feet up, relax with a cuppa, don't think too hard, simple storylines, beautiful scenery and so on. I do agree with someone else here who remarked on the lead character's dowdy hair styling; maybe no budget for hairstyler?
I've seen Claire coming out of her dressing room trailer at 7:30 in the morning with her hair in rollers heading for the catering truck for breakfast while on location and no, I didn't take any photos. I think I can safely say that her hairstyle is all her own, how many women do you know who go to the hairdresser every morning. I know this because my son was a member of the crew and as he hasn't yet passed his driving test I gave him lifts to the various location unit bases. Claire and the rest of the cast and crew are a pleasant and friendly bunch of people.
