On Sunday, at Pordenone Legge, a book festival in northern Italy, my interviewer, Chiara Valerio, challenged me to tell the audience something about Emily Dickinson (one of her poems has a cameo in Necessary Errors), who, my interviewer said, is currently having a bit of a moment in Italy. Somehow, a minute or two later, I found myself singing an Emily Dickinson poem to the tune of “The Yellow Rose of Texas.” And quindi, as the Italians say, when I was interviewed on the radio program Fahrenheit a few days later, the host, Loredana Lipperini, decided to ask me for a reprise, audible with all its involuntary tremolo here, if you click on the word “Ascolta.”
