In 1980, L Neil Smith turned the science fiction field upside down with the publication of THE PROBABILITY BROACH. Set in the (then) near future, it's the story of Win Bear, a Denver detective on the trail of a murder. But the trail leads him to another America, where things are different. In a world of zeppelins, intelligent apes who can vote and no federal government. Win solves his mystery and things are never the same for him again.
