Andrew Marr talks to Simon Wessely about the mental health of soldiers serving in Iraq and Afghanistan, and explores why British personnel appear to have fared so much better than their American counterparts. The historian John Stubbs revels in the antics of the Cavaliers - the 17th century dandies and political intriguers, loyal to the king. The experimental physicist Athene Donald argues that science is as creative as the arts, and describes how studying the texture of yoghurt could help the treatment of dementia. And Simon Sebag Montefiore studies the texture of a city - Jerusalem. His epic 3000 year history is a chronicle of faith and power, diversity and co-existence.

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.
