Dan Brown, author of one of the most popular and controversial books of the last century, The Da Vinci Code, spoke on Sunday, April 23rd in Portsmouth as part of our Writers on a New England Stage series. Brown talked about his famous book, its adaptation to a new film and the controversy surrounding both. In the second part of the show, host Laura Knoy joined him onstage for a few questions of her own. Today we broadcast some of that performance. (Note: This show is an edited version of the performance.)
