The worlds of Ray Bradbury jump from the page to the airwaves with four old time radio adaptations of his stories. First, a ventriloquist's dummy holds the key to a murder case in "Riabouchinska" (originally aired on CBS on November 13, 1947). Next, a little girl tries to save a woman in danger, but no one believes "The Screaming Woman" is real (originally aired on CBS on March 1, 1955). Finally, we'll hear a pair of Bradbury's classic sci-fi tales adapted for the airwaves. First, his novel "The Martian Chronicles" is presented on Dimension X (originally aired on NBC on August 18, 1950). And a group of astronauts wonder if "Mars is Heaven" on X Minus One (originally aired on NBC on May 8, 1955).
