Harper's: "What happened in Vegas"

An entertaining exchange, which the magazine introduces this way:

From The Lifespan of a Fact, by writer John D’Agata and Jim Fingal, published in February 2012 by W. W. Norton. In 2005, as an intern at The Believer, Fingal began fact-checking D’Agata’s article on the 2002 suicide of Las Vegas teenager Levi Presley. The book is based on emails exchanged by D’Agata and Fingal. The fact-checked article appeared in The Believer in 2010.
