A half hour Private Eye
TV show from 1958 that ran for three years, updating the Hardboiled Detective
ideals of the 1930's with 1950's notions of jazz cool. It featured the crime-solving skills of the title character (Craig Stevens), who got equal portions of help and hindrance from Lieutenant Jacoby. He hung out in a nightclub where his girlfriend was the singer; the owner often provided tips and clues to the crime.
Well executed, but mostly forgotten... except for the fact that Henry Mancini
's theme music is legendary, and still popular today.
