I really enjoyed this. I've pretty much ran out of new series ( I've been watching all the UK crime ones) and found this last night. I like how they keep you guessing throughout, did he didn't he. Well acted and good script. Stayed up til almost 4am watching all 4. I clapped at the end. Haha. I don't know why but I did. I highly recommend if you are into these type of series. Very good one!
