On Start the Week Andrew Marr talks to Robert Douglas-Fairhurst about the life of Lewis Carroll. Alice's Adventures in Wonderland has become an influential part of our cultural heritage but beneath the fairy tale lies the complex history of the author and his subject. Gillian Beer explores the links between Darwin and Carroll and the struggle to define and classify a changing world. The children's author Katherine Rundell enjoys the chaos and ambivalence in the Alice stories, and brings a sense of adventure to her own work. Centuries earlier, as intrepid travellers returned from distant lands with tales of wonder and exotic beasts, fearful hybrid monsters were all the rage as Damien Kempf describes in his Medieval Monsters.
