The Radio Menace — Ralph Milne Farley

From Pulpville Press: At the close of "The Radio Planet," did you ever wonder what had become of Doggo, the Ant Man, or Quivven, the Golden Flame? Well, this book answers all of your questions, as these two, aided by the Whoomangs of Venus, invade the Earth for conquest. Myles Cabot, the Radio Man, makes a brief, off-stage, appearance in this book.
