"One of the experimental texts Vidal refers to as his "inventions", "Duluth" describes both a novel written about Duluth (that, bordered on one side by Minneapolis and on the other by Michigan, bears scant resemblance to the real city) and a television series
of the same name; when residents of the city die, they end up as characters in the TV show, who can in some cases continue interacting with the living through the TV screen.When members of the cast of "Duluth", the TV show, die, they become characters in "Rogue Duke", a romance novel serialized in the pages of "Redbook", the popular women's magazine.
