At the start of the final season in 1971 of "My Three Sons", Francis played bowling-alley waitress Terri Dowling, who marries character Laird Fergus McBain Douglas of Sithian Bridge, Scotland, and returned to his homeland as royalty. (Fred MacMurray played the dual character roles of Steve Douglas and Fergus McBain Douglas in this four-part story arc.) She appeared twice as a guest star on "Columbo", once as the manipulated lover of the murderer ("Short Fuse", 1972) and once as the murder victim ("A Stitch in Crime", 1973).
