For your listening pleasure, here are three stories by the well known talents of Keith Laumer from the glorious days of Science Fiction in the early 1960s: A Bad Day for Vermin, The King of the City and Doorstep. They were all published in various Science Fiction magazines then flourishing in the United States at that time. I won't spoil your fun of listening to them by giving detailed story outlines, but be assured that there are aliens of various disgusting and/or beautiful shapes involved in several and a sad view of our future life when the US government collapses.
