Calling All Detectives ran from 1945-1950, the shows format was a combination of Quiz show and Detective drama. The host Paul Barnes played all the characters in each episode. His primary role was that of Detective Browning. Barnes would start the short crime drama then during a commercial break he would dial a random telephone number from the phone book, the listener would then try to figure the answer to the mystery, then Barnes would finish the rest of the original drama. Some of the listeners were unaware of what was going on during the phone call part of the show, this resulted in Barnes only calling the numbers that had been sent into the show from listeners.
