Spookmeister Stephen King has come up with a novel way to plug his new short-story collection: an online-video series based on one of the stories. The Wall Street Journal reports that Marvel Comics will remix the story, ”N,” into bite-sized video vignettes. The vignettes will be distributed in several online and mobile channels before the book, “Just After Sunset,” is published in November. The “Webisodes” kick off on Monday and will run five times a week, through Aug. 29.
