Radio’s stingiest would-be violin virtuoso Jack Benny traded puns for peril when he visited Suspense. Benny was the star of one of radio’s most popular comedies, but he proved himself quite adept in the dramatic world when he guested on radio’s outstanding theater of thrills. We’ll hear him in “Murder in G-Flat” (originally aired on CBS on April 5, 1951) and “A Good and Faithful Servant’ (originally aired on CBS on June 2, 1952).
