Philip K. Dick’s last wife has reworked the novel he was working on when he died in 1982 and is publishing the book herself....Ms. Dick said that a letter from her husband to his editor and agent revealed plans to “have a great scientist design and build a computer system and then get trapped in its virtual reality,” and added: “The computer would be so advanced that it developed humanlike intelligence and rebelled against its frivolous purpose of managing a theme park.”
