This year's Booksteve Channel Father's Day TV Father of the Year Award goes to...Inspector Richard Queen as played by David Wayne in the short-lived but top notch TV mystery series from 1975-76, ELLERY QUEEN.
Although the format of the series dictates that he never actually fully solve a crime, Inspector Queen is invariably shown to be a more than competent policeman, and, in fact, given a richer history and background than many supporting characters.
It's also shown that that he is and has been a loving and nurturing single father to Ellery. They fight and argue about a case but then immediately he might ask what Ellery wanted for dinner that evening.
With Jim Hutton's quirky and almost Autism Spectrum-like portrayal of Ellery unlike that of the literature version of the character, the writers and actors managed to take what could well have been a typical smart detective/dumb cop relationship and make it into one of the best father/son combos in TV history...even if the short-lived status of the series means that few people remember that.
