One of my all-time favorite television shoes is Columbo. I love how the seemingly dimwitted detective relentlessly unravels the mystery.
Consistently Columbo faces intelligent murderers who dismiss Columbo as a nitwit who they can easily outwit.
In one of my favorite Columbo episodes is Bye Bye Sky High IQ Murder Case.
Wikipedia explains that, after Bertie Hastings discovers that his friend, Oliver Brandt, a senior partner in an accounting firm, has been embezzling money to support the lifestyle of his wife, Brandt kills Hastings at the Sigma Society, a club for geniuses. 1
