Oscar-winner Edmond O'Brien headlines three old time radio mysteries, including a pair of audition recordings as investigative reporters. First, he's "the man with the action-packed expense account" in "The David Rocky Matter" (originally aired on CBS on January 20, 1951). Then, he plays reporter Hank Mitchell in the audition for Night Beat - recorded before Frank Lovejoy won the renamed role of Randy Stone (recorded May 19, 1949). Finally, O'Brien stars as a real Los Angeles reporter who helps to bring down a counterfeiting ring in the audition for The Fourth Estate (recorded June 26, 1946).
