With only two episodes to go, who do you think killed.....? SPOILERS
1. Grace Gibson?
2. Cara?
3. The Taxi driver (friend of the illegal one)?
4. The little girl in episode 6?
Any other relevant deaths? Was Marcella's daughter killed also? And if so, by whom?
...............
I think there are at least 2 killers, the main suspects are:
Jason - could have killed Grace because she was going to leave him as she had fallen inlove with somebody else and was having his baby OR to frame Marcella or make her crazy thinking she did it (blames her for their daughter's death?). Jason also could have paid somebody to kidnap the little girl who died in Episode 6, because he knew it was the anniversary of his daughter's death, and this would have hit a nerve with Marcella. Maybe the 'kidnap' went wrong and they had to kill the child before getting caught.
DI Tim Williamson - Too nice for my liking. He worked with Marcella before so knows all about the previous case, and about her personal life, including her daughter's death. He could have killed Grace and left her body where he knew Marcella would look, in Hampstead Heath. He would know about her 'rage' and blacking out episodes, so he would know this would drive her up the wall and she would think she was the killer. He also could have kidnapped the little girl in Episode 6 for the same reason, because he knew it was the anniversary of her daughter's death. He also had inside knowledge of who the police were looking for etc, so he also could have killed the Taxi Driver because he could be a future witness against him in Grace's murder. Did he actually get Cara involved in Grace's murder, asked her to help him 'move' something that night? (And this was the 'girl', the taxi driver saw? This would also give him a reason to kill Cara. Motives? Psycopath, or revenge for something we don't know about yet?
Sylvie Gibson (Grace's mother) - - Could have killed Grace if Grace had told her she was pregnant with Jason or even worse, Sylvie's husband. Jealous of daughter? Doesn't seem to be mourning much, seems more interested in the 'property deal' than in finding her daughter's killer. I wonder why? She also could have had Cara killed because she's the one who slept with her and it was her jewellery she had stolen. We saw that Cara also had older female clients, and therefore perhaps Sylvie was one of them.
Regarding Marcella's daughter's death....why are they keeping the circumstances of her death a mystery?
BTW I believe all the other 'suspects' (ie. nearly all the cast) are just red herrings.
Any thoughts on who is doing the killings and why?
