The Whisperer was an American old-time radio program which broadcast 13 episodes on late Sunday afternoons [5:00 p.m. Eastern] as a summer replacement from July 8 to September 30, 1951 on NBC.
Later, his voice is restored through surgery, but he continues to lead a double life as the Whisperer, relaying instructions by telephone 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.
In the prologue to the final episode from September 30, 1951 titled "Strange Bed Fellows", Philip Gault explains his history as follows: "It all began ten years ago when I was kicked in the throat while playing college football.
After a bakers dozen of women fainted when I spoke to them and countless babies went into paraclisms [sic] of crying, I disappeared from my usual haunts and went to work for a group which I later discovered were known as the crime syndicate.
William Conrad frequently appeared in different supporting roles under his alias, "Julius Krelboyne", as he was under exclusive contract to CBS radio at the time.
