I don't mean to spoil the episode in that summary of mine.
However, it must be said that the writing, directing, and finally the acting quality is god-like. A truly special episode of the Alfred Hitchcock Presents television series. Vincent Price is a detective who jailed an innocent man for something he did himself, that is "Murder." In the end he uses the same means to clean his tracks. However, the perfect crime does not exist. Television is fantasy, and in this day and age it is difficult to cover up man slaughter as Hitchcock can arrange. But it's great seeing the flow of dialogue and mind-blowing thought you undertake as you wonder how the episode will end.
