Host Meg Wolitzer presents three pieces about marriages that outlive the romance. In Etgar Keret’s “A World without Selfie Sticks,” performed by Tate Donovan, a man meets the woman of his dreams; but she’s from an alternate universe. “On the Honeymoon,” by Javier Marias, a husband has a strange encounter with a woman in the street. It’s read by Ivan Hernandez. And in Duncan Birmingham’s “The Cult In My Garage,” performed by Michaela Watkins, an old college buddy turns up, and he’s got a mission.
