Writer Damian Barr hosts this episode - the last of this series - from Hamilton Town House. From an intrepid pack of librarians on horseback to a brave and brilliant mother and a fictional pop star and protest queen, novelists Jojo Moyes and Kirstin Innes and American screenwriter Dustin Lance Black discuss the pure ‘gallus' characters at the heart of their books. There's poetry from Jenny Lindsay and this week's book group, who come from Edinburgh and West Lothian, tell Damian what they thought of Kirstin Innes' Scabby Queen.
