The Slime People
Robert Hutton – Les Tremayne 1963
Tom Gregory , a Los Angeles-based sports reporter, is flying into L.A. and lands his private plane after a rough descent through some kind of opaque midair disturbance, only to find the airport deserted. He meets Professor Galvin and his two daughters, Bonnie and Lisa, who tell him that the city has been overrun by huge, hulking slime-covered subterraneans called Slime People, who appeared out of the sewers and other underground water concentrations. Appearing out of a strange thick fog apparently generated by a device of their own, they’ve killed hundreds, possibly thousands, panicked the population, fought the army to a standstill, and have now cut off the city with a wall of solidified fog.
