Ellery queen? Da fukk is that
it was a murder mystery show, way ahead of its time. Starred Jim Hutton. John Hillerman was in about half the episodes. Only lasted one season.
Every mystery was solvable, you'd get right to the final clue, once it was shown Ellery would break the 4th wall and let you know he's solved it, ask you if youve got it. Give you a subtle hint or 2, and then gather all the suspects for the reveal. John Hillerman played like an offbrand radio star Ellery Queen type, and would often give a false reveal because he was terrible. The show was from the 70's and set in the early 40's.
In Leverage theres an episode where they all go to a costume party dressed as famous fictional detectives, Timothy Hutton goes as Ellery Queen and labels him "The Greatest Fictional Detective Ever"
