This Man Dawson (1959)

This Man Dawson is a syndicated drama television series starring Keith Andes as a former United States Marine Corps colonel hired to clean up police corruption in an undisclosed American city. The thirty-three episodes, in which Andes portrayed Chief Frank Dawson, aired during the 1959-1960 television season. The series was partly inspired by Andes’s Universal Studios film Damn Citizen, in which he played crusading Louisiana State Police Superintendent Francis C. Grevemberg.

The program narrator is the late William Conrad, formerly the voice on the radio version of Gunsmoke and later the star of CBS's Cannon detective series. The black and white half-hour series was filmed by Ziv, later part of MGM Television.
