In this special episode taped live onstage in New York, John interviews his pal Jonathan Freedland – Guardian political columnist and co-host of the Unholy podcast – about his new book, “The Traitor’s Circle: The True Story of a Secret Resistance Network in Nazi Germany – and the Spy Who Betrayed Them.” Freedland, the author of nine thrillers under the pen name Sam Bourne, describes how "The Traitor's Circle," like its predecessor “The Escape Artist,” marries rigorous research with the techniques of genre fiction to create a serious work of historical non-fiction that reads like an Agatha Christie mystery. The two also discuss how pop culture has processed the Holocaust, from “Shoah” to “The Odessa Files” and “Inglorious Bastards.”
