WHEN THE MOON TURNED GREEN

Episode #514 · Written by Hal K. Wells · Narrated by Scott Miller

Bruce Dixon expected the outside world to look exactly as he had left it three days earlier. Instead he steps out of his mountain laboratory and finds the moon blazing an unnatural green across the Arizona desert. Birds lie rigid in the grass. A prospector stares upward without moving. Every living creature appears trapped in a silent paralysis that mimics death.

The disaster is spreading across the planet in the path of the moon’s strange light. Within hours Dixon discovers the horrifying explanation: alien refugees from Alpha Centauri have begun the conquest of Earth by turning the moon itself into a weapon. The green rays flooding the atmosphere leave humanity helpless while grotesque hybrid creatures roam the land as enforcers for their unseen masters.

By chance and ingenuity Dixon discovers the one weakness in the invading strategy. Lead shields him from the deadly radiation, leaving him among the last free minds on Earth. With Emil Crawford’s experimental radio-guided projectile and Dixon’s newly created radium explosive, a single desperate strike might destroy the alien ship that is poisoning the moon from space.

But reaching the launch point means fighting through alien guardians, monstrous hybrids grown from spiders and insects, and the creeping paralysis that steadily drains Dixon’s strength. As the green moon sinks lower in the sky, every minute brings him closer to the same living death that has already claimed the rest of humanity.
