North By Southwest -

In this week's edition of "North By Southwest" Nicolas Jackson meets Philippa Gregory, the historian and writer whose passion for the Tudor monarchs has inspired six novels on this period of English history, including The Other Boleyn Girl, which was made into a major Hollywood film starring Natalie Portman, Scarlett Johansson and Kristin Scott Thomas, amongst others. We catch up with Philippa Gregory at Spain's largest literary festival, the Hay Festival in Segovia, were she came to discuss her work and to promote the Spanish edition of her novel The Red Queen, published by Planeta.
