This week, host June Thomas talks to writer Adam Sisman about his two biographies of the late spy novelist John le Carré. In the interview, Adam discusses how he managed to land such an exciting project and how he was granted so much access to le Carré, whose real name was David Cornwell. He also talks about his friendly but complicated relationship with le Carre and some surprising findings that almost derailed the whole project.  After the interview, June and co-host Isaac Butler share research tips for nonfiction book projects.  In the exclusive Slate Plus segment, Adam explains the importance of in-person interviewing.  Send your questions about creativity and any other feedback to working@slate.com or give us a call at (304) 933-9675.
