Though based on items from True Detective magazine, this series was usually sponsored by other interests. Not much is know of its earlies shows, its best-known and most durable format being the Mutual run of 1944-58. This was an anthology, with a "case history of an actual crime" offered each week. Some of the cases were more than 20 years old, but all were geared to proved that crime doesn't pay. _{John Dunning}
