I thoroughly enjoyed it, but want to know what happened to Sean, I guess he died, but then that should be investigated. So she became her sister in the end and that's how she knew who killed her, I loved it. I thought the killer's wife had an intruiging face, really strange. and why did the little daughter keep insisting that they had seen the missing girl and the mother denying it, had they? And who was the blonde girl on the railway station?
