In the latest microphilosophy podcast I talk to Richard Lloyd Parry, author of People Who Eat Darkness, and Tobias Jones, author of Blood on the Altar about how the experience of writing about true, gruesome crimes has affected their understanding of evil and human nature. The discussion was recorded live at Foyles bookshop in association with the Bristol Festival of Ideas.
