This was a fantastic episode which had very good ending. It reminded me of a morbid game I used to play as a teen--you know, the \"if you could marry anybody who would it be, if you had to spend eternity in a city, what would it be, if you could kill somebody, who would it be???\" 

In this episode, it proves that no matter what, your sins find you out. And even if you plan the perfect murder, it will sooner or later come out in the wash. 5 stars.
