Andrew Marr talks to David Attenborough as he goes on the trail of the elephant bird. Fifty years ago he was given pieces of its egg on a visit to Madagascar, now he returns to find out what this giant ostrich-like creature can tell us about the balance between survival and extinction. A journey of a different kind for Sheila Hancock who goes in search of the often over-looked artist of the watercolour. The writer David Shields heralds the death of the realist novel, as he advocates blending fiction and non-fiction in a kind of 'lyric essay', but he does it by plagiarising other authors in a form of 'creative sampling'. And poet Andrew Motion meditates on crossing the borders between fact and fiction.
