The Probability Broach
Denver detective Win Bear, on the trail of a murderer, discovers much more than a killer. He accidentally stumbles upon the probability broach, a portal to a myriad of worlds—some wildly different from, others disconcertingly similar to our own. Win finds himself transported to an alternate Earth where Congress is in Colorado, everyone carries a gun, there are gorillas in the Senate, and public services are controlled by private businesses.
