This seems to me as one of my favorite shorrt stories written by Ray Bradbury. The story is so inordinary that you almost have no idea what to take from the text. As Doug plots to kill Ralph Underhill. This statement is so random until u=you further your reading in the story. The utterly Perfect Murder, is a contradiction in itself by the fact that the murder plot seemed perfect, but the fact as to if the murder was ever carried out is a mystery.

Well the only perfect murder that can be carried out is in the mind don't you think?
