Broadcast History: 7 April 1945 to 25 August 1945
Calling All Detectives was both a mystery and a quiz show. It aired daily for fifteen minutes on Network with a melodrama of eight minutes. The following five minutes were handed over to local affiliate radio stations when announcers would telephone prior contestant listeners and ask them to identify the perpetrator. The show would then rejoin the Network for the concluding part of the story and the local station would then award prizes to their listeners who had correctly identified the culprit.
