Here's a mystery. The Vanity Fair article has Cormac McCarthy running off to Mexico in 1977 with a teenage girl. But in a 1974 letter to Hugh Kenner, Guy Davenport mentions that McCarthy had just run off to Mexico with a teenage girl. Did McCarthy do this more than once? Did Vanity Fair get the date wrong?
Re: the Cormac McCarthy story. In 1973 and 1974, McCarthy was editing Guy Davenport's first story collection, Tatlin!, making many severe strictures. Then, McCarthy disappeared. In a 1974 letter to Hugh Kenner, Davenport explained what happened.
