I am sure you probably already watching this but if not then I can't recommend it highly enough! It's one of the most gripping dramas I've seen in a long time, in fact, possibly ever. The suspense is off the chart! Watching it last night I could barely move and could feel the adrenalin racing around my body, literally! It's fast paced and action packed but also laced with emotion & passion, it's so high octane in every aspect! I love it. The only problem is it might keep you awake for hours...Thank you BBC for yet another brilliant tv series! You can watch it on catch up here.
