One of the best episodes so far. Maybe I'm wrong, but I haven't seen a show so far where you find such compassion in the most unexpected ways. It seemed until now there's who you suspect of murder, who's really guilty and the victims. You expect this compassion to come at first, in the middle but then there's almost always the cold hearted murderer to balance it all out.
That's why at first when they place a pretty well-known actress as one of the suspects that she would be the murderer (they've done that before). They've also had an episode where one character that was believed to be framed was really the murderer so no excitement there.
But what was different in this episode was that it wasn't enough just to know who the murderer was. It wasn't an episode where there's only a murderer and a victim. Hell! There were even 2 that is not what made the episode so great for me. It was the meshwork in pulling the whole story together, and the surprise at the end. Even if you guessed the murderer you didn't necessarily guess the ending, and yet such a deep one.
