Childish Laughter
Description
A researcher visits a spooky old house after barely getting away from a ghostly young girl he met while driving. He tries to ignore the sound of a child laughing that fills the rooms, but when he sees an old painting and remembers the terrible thing that happened because of a formula he created, he learns what really occurred.
CBS Radio Mystery Theater is a radio drama series created by Himan Brown that was broadcast on CBS Radio Network affiliates from 1974 to 1982, and later in the early 2000s was repeated by the NPR satellite feed. In New York City it was not aired by the then all-news WCBS but by its originating station, WOR, which produced and announced it as simply Radio Mystery Theater.
