Norman Maclean published A River Runs Through It when he was seventy-three, and only after his children implored him to write down the stories about fly-fishing, brotherhood, and the wilds of Montana that he’d told them for years. The resulting novella is a classic of economy and clarity. A few years later, Pete Dexter visited Maclean in Montana and profiled him for Esquire in “The Old Man and the River.” Dexter, a National Book Award winner, joins host David Brancaccio to discuss the master class he got from Maclean in what truly matters most—in writing, nature, and life.
