this is way at the top of my list of favorite episodes. I love how Columbo chases Oscar across town toward the beginning of the episode.
I love the scenes with the Congressman too, he has one of my favorite lines of people talking about Columbo, "he's got an act you could take on the road."
The victim is interesting in this one. Someone describes him as "one of our city's most notorious racketeers", but when you see him he's this jovial character that says everything with a chuckle, even when he's threatening you.
And this episode features TWO secretaries prominently. Both the murderer's and the victim's. The victim's secretary was so devoted to him that she goes into a near catatonic state after his death. I realize I am preoccupied with secretaries, I can't help it.
