Escape From Pluto by William Oberfield

Marcius Kemble stood upon the frozen surface of Pluto and swore aloud. He knew there were none to hear him but, just the same, he shouted into his plastic space helmet until his ears were ringing, cursing all the planets and their diverse inhabitants in order, most of all Earth.

You see, Marcius Kemble was an example. He was an example to any others, in the year of twenty-two hundred A.D., who would strive to rule the solar system. The planets were independent states and they were to remain that way. For trying to change this, Kemble had been exiled to unexplored Pluto.

Marcius raised his mailed fist toward the mighty stars and ground out curses against Earth and all those upon it, wishing that he could call upon it the wrath of Heaven and Hell, for it had been the men of Earth who had brought about his ultimate downfall.

It had been the age-old story of a power-mad tyrant finding out the secret grudges of his subjects and working on them to inspire a frenzy of hate, to maneuver them into a war against unsuspecting neighboring nations. He had gained control of the whole of Mars in this way and had been reaching out for the moon-system of Saturn, when the full force of the Planetary Combine had come against him, scattering his forces.

The counter offensive had been led by Earth, and it had been an Earth ship which, after his short-lived escape, had parachuted him to the cold surface of Pluto. Is it any wonder that he should hate them?

Marcius Kemble looked fearfully around at the bleak, frozen landscape of Pluto, a cold Hell, hardly reached by the light of the sun. Then he began to laugh.
