The city council sought to clean up the red-light district by renovating the streets and cleaning up the shops. Its latest initiative went too far as to puritanize the public; the proposition set a nine-o-clock curfew, banned all other mind-altering substances, and even fined all public displays of affection. They named it heaven-on-earth and sectioned off the district to run an experiment. Those invited would have their basic needs provided for but could not leave for a full decade. Those who attempted to depart through alternative means were marked with a halo. Many halos hung by decade’s end.
