Going Gray with Christy Potter - with guest Brian Kannard

I'm Christy Potter. A longtime journalist turned author, I now love to get out and meet people who have interesting stories to tell. They may not make the headlines, but these are the people who keep the world fascinating, fun, and inspirational. Today I talk with author Brian Kannard, whose latest book, "Steinbeck: Citizen Spy" reveals hard-core evidence that the beloved writer was also working for the CIA.
