After losing his newspaper job, Morse brought several scripts he had written throughout the 1920s to an interview with NBC. He soon was offered a job at KGO, the San Francisco outlet of NBC's Blue Network, and began his radio career scripting House of Myths. Morse began work on NBC Mystery Serial, which included such episodes as "Captain Post: Crime Specialist" and "Case of the One-eyed Parrot". Other mysteries scripted by Morse included The Witch of Endor, The City of the Dead, Captain Post: Crime Specialist, The Game Called Murder and Dead Men Prowl.
