You know what it's like - just one more episode then I'm going to bed then before you know it you've done the whole thing and it's 2:00am on a work night! I have no idea who has rated this low but they were not watching the same thing as me! I was gripped and can't quite believe that the police, those that are here to protect us, could behave so despicably, so devious and blinkered. No spoilers but just wait until the last two episodes! Absolutely amazing!!!
