This summer's second Underappreciated segment looks at David Markson's 1988 novel Wittgenstein’s Mistress, which David Foster Wallace called “pretty much the high point of experimental fiction in this country.” Ann Beattie, longtime admirer and friend of David Markson, and Françoise Palleau-Papin, professor of American Literature at the University of Paris III (Sorbonne Nouvelle), discuss Markson's work.
