The Ghost with a Knife

Based on supposedly true events, this tells the tale of a family terrorized by a ghost with a blade who destroys their garden and keeps changing their temperature settings. Paranormal investigators attempt to communicate with the spirit and figure out why he acts so oddly.

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.
