Feisty, fiercely independent Maureen O'Hara - the red-headed Irish-American leading lady of old Hollywood - made only one visit to "radio's outstanding theater of thrills," but it's a great episode that finds her playing a strong woman stepping up to track down a killer. It's "The White Rose Murders" (originally aired on CBS on July 6, 1943). Then she recreates her screen role from How Green Was My Valley in a broadcast from the Gulf Screen Guild Theatre (originally aired on CBS on March 22, 1942).
