In try and catch me, what the $*&%#! is Abagail Mitchell thinking when she gives Columbo the keys? Makes absolutely no sense. I guess the senility was kicking in.
All I know is that Abby exerted an incredibly amateurish approach for such an accomplished mystery writer, but then, they had to make it easy. This is why season 5 is the end of the series in my book.
By the way, the luncheon club where Columbo addresses the ladies in attendance about being a cop can be seen in a Rockford Files episode entitled: "The Farnsworth Strategem".
