Before she menaced puppies as Cruella de Vil, Betty Lou Gerson was one of radio's busiest character actresses. Her husky voice and powerful characterizations added flair to shows like Suspense, Escape, Johnny Dollar, and Sam Spade. We'll hear her as a murderess trying to stay a step ahead of her conscience in "Beyond Reasonable Doubt" from The Whistler (originally aired on CBS on July 16, 1947). Then, she co-stars in "The Indian Giver" from The Adventures of Philip Marlowe (originally aired on CBS on August 13, 1949).
