Sounds more like Blade Runner or one of the other Phillip K Dick books...As for Fool in the City's storyline...believe it or not,it features Falk Rogner as the protagonist in a futuristic city...ala Logan's Run,where rock and roll is outlawed.Rogner is a faithful enforcer to a powerful artificial intelligence,mainting the law and order inside the city,until he accidently kills the leader of the underground resistance,and finds himself leading the resistance....it's about as much as I can remember.
I vaguely remember this being discussed on Wax Trax some time ago, and I seem to recall that Rogner wasn't the only person from FSS to appear in this, some of the fatimas make apperances (not necessacealy as fatimas but the characters copy over)
Is Fool For the City IN the FSS timeline or is it a parallel storyline? This was also discussed way back when but I don't recall if a answer was even determined..
It also sounds like it would make a good movie. Its shorter than trying to adapt a whole serial as long as FSS to a screenplay.
