Calling All Detectives
Calling All Detectives is an American radio mystery program. A 30-minute version was broadcast on the Mutual Broadcasting System April 7, 1945 - August 25, 1945. A 15-minute version was syndicated from 1947 to 1950. The first program of its kind, the Mutual version featured "nation-wide audience participation".
Mutual version
Each episode of the program began with a mystery that listeners were challenged to solve. Immediately after the climax of the mystery segment, control of the broadcast switched from the network to local stations for five minutes. At each station, an announcer selected a postcard from those sent in by listeners and called the person whose card was selected. If the person solved the mystery correctly, he or she received a war bond. When the local segment ended, control went back to the network for the conclusion of the story. Personnel at each station called the selected person during the initial network segment to ensure that he or she was at home. Values of prizes varied from station to station; at each station if the person called gave an incorrect answer, the prize value was increased for the next week.Opening with "a whodunit narrative", each episode included clues provided by a narrator named Robin. The clues were designed to help listeners determine who committed the crime. Vincent Pelletier portrayed Robin, and Paul Barnes played detective Browning. Owen Jordan and Frank Lovejoy were heard in supporting roles. The announcer was George Bower, and Dick Platt played the organ. Kenneth Houston was the writer, and Alan M. Fishburn was the director. Sealy Bedding Company was the sponsor. The show was broadcast on Saturdays at 9:30 p.m. Eastern Time.
