Luca Turin moved to Nice, France when he was a young man. He was entranced by the region's beauty, and by the strange, dusty bottles of perfume he found at local flea markets. It was one perfume - the evocatively-named Nombre Noir - that initiated Luca into what would become his career. He spent the next 15 years studying the secret of smell. Also in this episode, Sy Montgomery traveled all over the world writing about nature, and thought she knew about animals. Then she was given a sickly runt of a pig. She named him Christopher Hogwood and, as she tells Dick, remained infatuated with Christopher even after he became a 750-pound eating machine.
