Baur succeeded Barbara Anderson in portraying a female detective on NBC television's Ironside, as her character of Fran Belding replaced Anderson's Eve Whitfield. In 1972, she told a reporter: "They interviewed 100 girls for this role. Then they had 14 of us come in and read for the part. Finally they gave seven of us screen tests. I was really surprised they chose me." Two years later, she said, "Officer Fran Belding is the hardest part I've ever had to play, because she's so straight, so normal."
