Crime doesn't take a rest during the holidays. Fortunately, radio's best gumshoes are working on Christmas to keep the airwaves safe. In the annual "Down These Mean Streets" holiday special, we'll hear four gumshoes and super sleuths in Christmas capers. First, Les Damon is private eye Mike Waring, aka The Falcon, in "The Case of the Unwelcome Christmas Present" (originally aired on NBC on December 24, 1950). Next, it's "that most famous of all manhunters" – Nick Carter, Master Detective. Lon Clark is Nick in "Nick Carter's Christmas Adventure" (originally aired on Mutual on December 25, 1943). Then, we have a Saint – not Nicholas, but Simon Templar. Vincent Price stars in "Santa Claus is No Saint" (originally aired on NBC on December 24, 1950). Finally, we head to London with Basil Rathbone and Nigel Bruce in "The Night Before Christmas" from The New Adventures of Sherlock Holmes (originally aired on Mutual on December 24, 1945).
