Dr. Bloodmoney — Philip K. Dick

Thermonuclear war has just ravaged the planet leaving only pockets of civilisation. Walt Danger-field, an astronaut, remains in space to broadcast music and culture and organize what is left of this peace-loving post-bomb society peopled by biological freaks. But Bruno Bluthgeld alias Dr. Bloodmoney, a bungling scientist and unrepentant megalomaniac obsessed with international communist conspiracies, comes back to threaten the new status quo. And then young Hoppy, an armless and legless victim, also makes a stand for world domination by using his special gifts of telekinetic know-how.
