Episode 2 revealed still more entanglements. Ruth Wilson is excellent as the bottled up middle class Englishwoman, but now that her sons have found out some of the truth, how will she cope? Alex's job is shady, to say the least. What was all that about his arrest in the park? I'm hoping that all will be revealed in the final episode, but as this is a real life drama, tying up all the loose ends and answering all the questions raised could be difficult.
