Dick Powell reinvented himself as a hardboiled hero with his performance as Philip Marlowe in Murder, My Sweet, and several films noir and radio detective shows followed. We'll hear Powell as gumshoe Richard Rogue in "Blood on the Sand" from Rogue's Gallery (originally aired on Mutual on December 13, 1945). Then he's Richard Diamond, Private Detective in "The Martin Hyer Case" (originally aired on NBC on July 23, 1949).
