Dial M For Murder - 8/10.
My dislike for mystery movies tends to be the necessity for things to come out of nowhere in the course of solving a murder, but here, I ain't got nothing to worry about. You know who, you know how, it's just a matter of waiting to see how the killer will eventually fuck up. It a mindtrick. In other words: it's magic. I think this is how every episode of 'Columbo' works. I should watch 'Columbo.'
