Temple Trouble

What if Earth existed in countless parallel versions, each timeline completely unaware of the others? That's the premise H. Beam Piper explores in this sharp little gem of speculative fiction. Everything works fine until one timeline develops the technology to slip between realities, and suddenly the ParaPolice have a very complicated job on their hands. Someone's been messing with the timeline, and it's up to them to sort out the mess before the fabric of reality unravels entirely. The beauty here is in the premise itself: cosmic consequences filtered through the lens of competent, somewhat exasperated professionals just trying to do their jobs. Piper builds an entire mythology around para-time travel with playful efficiency, treating interdimensional chaos as a bureaucratic inconvenience. It's the kind of story that makes you look at the world and wonder which version of yourself is reading this right now.
