John of Gaunt: with Helen Carr

In the second episode of Series Two, Dr Nicola Tallis is joined by fellow historian and author Helen Carr to explore the story of English prince, military leader, statesman - and the third of the five sons of King Edward III - John of Gaunt.

Helen, whose book The Red Prince, a biography of John of Gaunt, is out now (but it here), tells Nicola about the controversial Duke of Lancaster and the pair delve into his love life and the story behind the famous SS collar.
