I was so confused by this episode! I must be very tired or something! Spoilers below for those who have not seen episode.
Was Nicola's character the real Abbey or not in the end? The episode ended without you seeing if there was a body and I just couldn't tell if she actually was just a performer con woman or if she was Abbey who later became a performer and got mixed up in the whole thing? I mean I *think* she was a con woman but I'm not sure? And also, according to the BBC website her character in this was a serial killer? When was that ever revealed in the episode? What did I miss?
