The Inner Sanctum Mysteries

Taking its name from a popular series of mystery novels, Inner Sanctum Mysteries debuted over NBC's Blue Network in January 1941. It featured one of the most memorable and atmospheric openings in radio history: an organist hit a dissonant chord, a doorknob turned, and the famous "creaking door" slowly began to open. Every week, Inner Sanctum Mysteries told stories of ghosts, murderers, and lunatics.
