Guest host Robert Sean Leonard presents a tribute to the classic TV series, “The Twilight Zone,” including two stories that were featured on the show: Price Day’s “Four O’Clock,” read by Zachary Quinto, in which a man with awesome powers knows just how to improve the world. And “Perchance to Dream,” by Charles Beaumont, in which the lines between sleeping and waking blur. It’s read by Zach Grenier. Roald Dahl’s “The Landlady,” is the perfect hostess, thinks the unwary young man who comes to her door. It’s read by Sam Underwood.
