We're setting sail with three old time radio detectives who find capers on cruise ships. First, Basil Rathbone tries to stop a shipboard poisoner in "Murder by Moonlight" from The New Adventures of Sherlock Holmes (originally aired on Mutual on October 29, 1945). Then, Bob Bailey is undercover as a cruise athletic director to catch some smugglers in "Serenade to the Southern Star" from Let George Do It (originally aired on Mutual on June 13, 1949). And finally, Frank Sinatra is Rocky Fortune as he tries to clear his own name and solve "The Shipboard Jewel Robbery" (originally aired on NBC on October 20, 1953).
