The original radio show began portraying Japanese and German characters as villains after Pearl Harbor. The producer, Edward Byron, observed "If radio characters don't get into war work soon, listeners will demand to know why they haven't joined the Marines".
"The Case of Baby and All," one of the original radio episodes available online, is actually a composite of two episodes "Baby and All" and an unknown episode dealing with a gambling ring. It segues into the latter case after the young man has been murdered.
