Will Storr is an award-winning writer. He has written fiction and non-fiction and over the years has become an expert on storytelling itself. For years Joseph Campbell's 'Hero's Journey' has been used as the way to craft 'perfect stories' and in recent years there have been attempts to crack the 'bestseller code'. Will looks at the actual science behind stories and why we tell them to ourselves and others. It turns out we can learn a lot from the ultimate storyteller; the human brain!
