The first episode showed potential but I was not overwhelmed by it.
The second episode very much wore its influences on its sleeve. Now you just have to figure out how much of the Wicker Man is there going to be. Will Grace be the sacrificial goat?
Grace is being goaded by some of the locals and particularly by her predecessor Gruffudd Prosser. He is not happy as Grace blames him for the ineffectual search for Cai Prideaux.
The discovery of his body brings over a police team from the mainland led by Ann Fletcher (Jill Halfpenny.) She certainly has a passive/aggressive thing going on with Grace. For a start she very much demotes Grace from the investigation.
Only while Fletcher thinks that Cai might have ended up getting lost or stranded. Grace very much comes with the opinion that it was murder.
By now you really do think there is a conspiracy and just who is on it. I liked the scene where Fletcher throws the mobile phone into the sea as she departs the island. While Grace furiously wants to let her know that new evidence has been found.
