I am still with it but can't say I've worked it out. I know who I think it is but I've nothing to support that. I think there's wall to wall red herrings kicking about.
I have to watch every episode twice to try to understand what's happening, it was difficult enough with two time frames and now we have a third to get our heads around! I'm really enjoying it though, you really have to concentrate otherwise it's easy to miss small clues and it makes a nice change to not be able to work out 'who dunnit' in the first 30 minutes.
Looking forward to the last episode next week
People who are wrong are just as sure they're right as people who are right, the only difference is they're wrong
