When the mail arrives for George Valentine and Dan Holiday, it means mystery and adventure are soon to follow. Both gumshoes find cases in the responses they receive to their newspaper ads offering their help to people in dangerous situations. We'll hear Bob Bailey in "Destination: Dead End" from Let George Do It (originally aired on Mutual on February 14, 1949). Then, Alan Ladd stars in a pair of syndicated episodes of Box 13 - "Book of Poems" and "The Great Torino."
