Really can't believe they only did 4 episodes. Never heard of this before, I always miss bbc series until years later. But I've watched all 4 and I enjoyed it very much, a lot of unanswered questions that could have been filled in with the extra episodes if required. It's a shame really. Could have been an excellent show. But overall I did enjoy the drama, good cop trying his best but doing bad things at night!! Watch out criminals coz you could be on his death list if you carry on. Watched it as I remember the lad from Luther, so thought I'd give it a try, think I'm only ten years late watching this.
