Kate Adie introduces BBC foreign correspondents with the stories behind the headlines. Prague; Budapest; Warsaw. Our correspondent takes the train on a journey which illustrates how, in some ways, Europe is more joined up than ever before. Another is in the slums of Nairobi, trying to find out how a friend was murdered. A young soldier is baptised in the Helmand River in Afghanistan, and our hypochondriac reporter in LA has a close encounter with the US healthcare system and, he says, only just survived to tell the tale.
