Claire Danes/Matthew Rhys Excellent acting throughout. The killer is the suspected killer from scene one . . . a nice change. Danes (Agatha) has blamed the death of her son in a car accident on the other driver (teenager, maybe drinking) but we learn she was a distracted driver definitely to blame as well. Ending, unfortunately, was ho-hum. Nile's (Rhys) second wife becomes suspicious that he is the killer, confronts him. They argue . . . he screams YES, I KILLED HER. Ah, but she has turned on the record feature of her iPhone and he's cooked. He gets murdered in prison, just to satisfy viewer that justice has been served. Danes writes her book and presumably it's a huge success. Last scene is her at a reading crying her heart out. All in all, very good. Too bad the ending was so conventional.
