San Francisco Police Commissioner Stewart "Mac" McMillan and his amateur detective wife keep their marriage unpredictable while solving the city's most baffling crimes.
Martha Raye made several earlier appearances as Agatha before becoming a regular on the show.
Police commissioners are administrators, not investigators. They would not have the time (and potentially lack the ability) to solve crimes. In fact, the involvement of the commissioner in an active investigation would likely be used by the defendant in any appeals if they were convicted.
