The Whisperer was an American old classic radio program which broadcast 13 episodes in summer replacement from July 8 to September 30, 1951 on NBC.

It was based on stories by Stetson Humphries.

The plot

Lawyer Philip Gault (Carleton G. Young), due to an unexplained accident, lost his voice and can only speak in an eerie whisper. Gault infiltrates "the syndicate" in his native Central City to bring down organized crime from within; to the underworld, he becomes known as the Whisperer. Later, his voice is restored through surgery, but he continues to lead a double life as the Whisperer, relaying instructions from the syndicate bosses in New York (who don't know he's a mole) to their lackeys in Central City, whom Gault is actually setting up. Betty Moran portrayed Gault's girlfriend, Ellen, the only person who knows Gault's double identity.

Bill Karn was the producer-director, and organist Johnny Duffy supplied the background music.

The radio actor Carleton G. Young is sometimes confused with the film actor Carleton Scott Young.
