It's a stand-alone story that takes place several weeks earlier than Chapter 1 of the serial. The plot is that Miranda Grossman, who will soon be Paul's girlfriend, starts an affair with her new roommate Vivian. But later Paul will start his own affair with Vivian, so everybody is misbehaving eventually. How will it all turn out? I don't know yet. This is happening in the Kingsbridge Heights section of The Bronx in the summer of 1977.
