Roy Jenkins guest is a nun who is one of the world’s best-known campaigners against the death penalty. Sister Helen Prejean came to international fame when she was played by Susan Sarandon in the Academy award winning film Dead Man Walking, based on her best-selling book of the same name. She has had direct dialogue with two popes, and is credited among those who’ve helped move the Catholic Church into opposition to capital punishment in all circumstances. Helen Prejean has witnessed the trauma of men being executed on six separate occasions, but the willingness to put herself through this, like her worldwide campaigning, required first a revolution in her own thinking - not least in her understanding of her faith. In a new book River of Fire, she describes her spiritual journey, with passion and humour. This programme was first broadcast in February 2020.
