I never paid any attention to it when it came up on the iplayer list but felt compelled to start watching it when I saw an advert via Facebook.
It was seeing Ruth Wilson in it that made me intrigued, as we're also watching Mrs Wilson atm.
I have to say it is absolutely compelling g viewing, even though we're only on episode 2 series 1.
We're watching Doctor Who tonight, but my evenings are going to be full for the next few weeks to catch up!
