Hope you brought your appetite - this week's show features four mysteries set in the world of food. From restaurants to the grocery store, our detectives have a lot to chew on in these cases. First, Boston Blackie investigates a murder in a Chinese restaurant and Dan Holiday comes to the aid of a beleaguered restauranteur in "Tempest in a Casserole" from Box 13. Dick Powell goes undercover in a butcher's shop in Richard Diamond, Private Detective (originally aired on NBC on January 7, 1950) and Johnny Dollar gets a deadly dinner invitation in "The Fatal Filet Matter" (originally aired on CBS on May 10, 1950).
