This is his recent appearance as guest on NPR's Fresh Air, hosted by Terry Gross. I didn’t listen to the whole thing -- it's about 45 minutes -- but did listen for 25 minutes, and thoroughly enjoyed it. What I heard is mostly about his life as a spy and his analysis of politics today surrounding Russia and Trump. Thanks to Eric Boardman for bringing this to my attention.
I don’t know if he gets into his writing later, though he reads a few passages from the book -- and most-especially when he reads from the first page (about a minute in) he’s tremendous. So good that you want to hear him read the whole book. So, even even you have no interest in listening to the whole thing, or even any, it's definitely worth checking out the first two minutes, if only to hear what it's like when an author is magnificent reading from his own work.
