Started last Friday, repeated on Tuesdays, Sky Living channel in UK at 9pm. If you didn't see it, you missed the first episode but I'm sure it'll be on catchup.
<insert youtube trailer here>
At work at the moment so can't get on youtube
Here is IMDB link instead: http://www.imdb.com/title/tt2741602/
Really enjoyed it myself. Did anyone else see it?
