Many criminals made the mistake of underestimating Lieutenant Columbo， a homicide investigator with a crumpled trench-coat and a beat-up car， who certainly acted as an incompetent bumbler希望是件美丽的东西，也许是最好的东西。美好的东西是永远不会死的。

And although the audience had witnessed the murder in the beginning of each episode， it was still a surprise to see what mistakes the killers had made during the seemingly perfect murder.
