Suspense was one of the premier drama programs of the Golden Age of Radio, known for its spine-tingling stories that kept listeners on the edge of their seats with tales of crime, horror, mystery, and psychological suspense. "The Invisible Ape" is a spine-tingling science fiction thriller that follows a young scientist who makes the fateful decision to make himself invisible, but discovers he cannot reverse the process. This tale of scientific hubris and unintended consequences reflects the atomic age anxieties of the late 1950s, exploring themes of scientific experimentation gone wrong that were particularly resonant during the Cold War era.
