True Detective Mysteries dramatised cases taken from True Detective magazine, broadcast on Mutual from 1937 and later sponsored by Listerine and Oh Henry. Each week presented the case history of a real crime, often narrated from the offender's point of view, and several broadcasts closed with an appeal for information on a fugitive still at large.

The shape of the run

What survives, year by year

5 dated broadcasts across 8 years on the air, with 7 years where nothing is known to survive. Brightness is transfer quality; empty cells are months lost to time.
