This is a new BBC crime/mystery show that is premiering on BBC America on Wednesday at 8/7. It does repeat several times during the week and I suspect that if it's successful, it will probably get a run on PBS in the future. The word of mouth is quite good and I'll definitely be taking a look. It showed to very good ratings in Britain this spring.
Fox is also supposed to be making a version of this show, but I don't watch American versions of British shows. I always enjoy the original.
Here's a link for anyone else who might be interested. http://tv.nytimes.com/2013/08/07/arts/television/broadchurch-a-dark-drama-arrives-on-bbc-america.html?partner=rss&emc=r ss
