As 2015 draws to a close we are republishing some of our best documentaries of the year. Nigerian-born Inua Ellams, a London-based writer, created the story "Dolphins" as part of "The Refugee Tales", works about the journeys of refugees and migrants seeking safety in Britain. Ellams worked with children who have made treacherous journeys across desert and sea, and wrote the stories based on their experiences. In this video, Ellams reads extracts from "Dolphins" and speaks about his collaboration with the children and his own background as a migrant.
