Colson Whitehead is one of the most lauded writers working today. His 2016 novel “The Underground Railroad” won the National Book Award and the Pulitzer Prize for fiction; he won the Pulitzer again for his next novel, “The Nickel Boys,” in 2020.  His career is notable for hopping from genre to genre. As an artist, he tells David Remnick, “it seemed like, if you knew how to do something, why do it again?” Whitehead is again trying something new: a sequel. He’s following up “Harlem Shuffle,” his 2021 heist novel, bringing back the furniture salesman and stolen-goods fence Ray Carney. He talks to David Remnick about how he mined the language of mid-century furniture catalogues, and his interest in teasing out the nuance in his characters. “I’m exploring different ways of being a criminal and trying to think about who actually is bad,” Whitehead says. “Carney has this secret self, this criminal self. But I think all of us have these different uncivilized impulses in us that we have to tame in order to function in society.”
