Vikas Swarup is author of the book that became Danny Boyle's "Slumdog Millionaire" (the best-reviewed movie of 2008 and the best-reviewed Indian-themed movie since "Gandhi"). Calling in from South Africa, where he is India's deputy ambassador, Swarup will discuss the movie and his book, "Q&A." Here's just one testimonial from the worldwide acclaim the book has received: "A very clever story told very cleverly and at a relentless pace" - Syndey Morning Herald.
