Fawcett Movie Comic #15

A young woman named Enid witnesses a strange glowing ball descending near her home and encounters a visitor from Planet X, who she initially mistakes for a horrible creature. The alien visitor—a man from another world—reveals himself to be friendly but warns of danger from Dr. Mears, a brilliant but unscrupulous mathematician allied with an enemy creature bent on controlling Earth through scientific forces. John and Dr. Mears reach a space vehicle where Enid is being held captive, and after a rescue attempt and confrontation with the alien enemy, the men send a desperate message to London requesting help from Scotland Yard. The story concludes with authorities discovering a red space ball in the English countryside, confirming the incredible tale.
