The Lincoln in the Bardo author is back with another metaphysical tale. He discusses Buddhism, partisan politics and the terrifying flight that changed his life

Like his first novel, Lincoln in the Bardo, which won the Booker prize in 2017, George Saunders’s new novel is a ghost story. In Vigil, an oil tycoon who spent a lifetime covering up the scientific evidence for climate change is visited on his deathbed by a host of spirits, who force him to grapple with his legacy. What draws Saunders to ghost stories? “If I had us talking here in a story and I allowed a ghost in from the 1940s, I might be more interested in it. It might be because they are in fact here,” he says, gesturing to the hotel lobby around us. “Or even if it’s not ghosts, we both have memories of people we love who have passed. They are here, in a neurologically very active way.” A ghost story can feel more “truthful”, he adds: “If you were really trying to tell the truth about this moment, would you so confidently narrow it to just today?”

Ghosts also invite us to confront our mortality and, in so doing, force a new perspective on life: what remains once you strip away the meaningless, day-to-day distractions in which we tend to lose ourselves? “Death, to me, has always been a hot topic,” Saunders says. “It’s so unbelievable that it will happen to us, too. And I suppose as you get older it becomes more …” he puts on a goofy voice: “interesting”. He is 67, grizzled and avuncular, surprisingly softly spoken for a writer who talks so loudly – and with such freewheeling, wisecracking energy – on the page. He says death is close to becoming a “preoccupation” for him and he worries that he is not prepared for it.
