With these words, Sergeant Preston and his loyal dog, Yukon king always got their man. Played by Richard Simmons, Sergeant Preston patrolled the western reaches of the Canadian frontier in the 1890s. Action and justice in such locales as Yellowknife, Dawson, and Whitehorse were seen each Saturday morning by the same kids who had just finished watching The Lone Ranger and Sky King.
The series episodes featured stories set against the harsh extremes of the Yukon winter and summers in the Canadian Rockies. To match the climate, Preston would trade his dogsled for his horse, Rex. King was along wherever the good sergeant went.
Simmons was the perfect embodiment of Sergeant Preston, the pride of the Northwest Mounted. To this day (despite Due South) when I picture a Mountie......it's always Sergeant Preston. And of those of who watched the show as kids, who can forget that stirring theme music and the words with which Sergeant Preston closed each episode, "Well King, this case is closed."
