Start the Week - Thomas Heatherwick on design and architecture

On Start the Week Andrew Marr goes in search of ancient landscapes with the writer Robert Macfarlane. With a mix of geology, cartography and natural history, Macfarlane journeys on foot to explore ideas of pilgrimage, trespass and ancient pathways. Jonathan Meades is equally preoccupied with a sense of place, but turns his attention to its architecture and the futility of landmark buildings. Anna Minton argues against the increasing privatisation of public space. And size is no matter to the designer Thomas Heatherwick - from a new London double decker, to a bridge that curls up and a handbag made from zips - he always has the human scale in mind. Producer: Katy Hickman.

World Book Club - Amitav Ghosh – The Shadow Lines

This is the last edition of the London Calling season of World Book Clubs - which have been going out each Saturday during May.

This week the programme are guests of The Nehru Centre - the cultural wing of the High Commission of India in London - and we're talking to acclaimed Bengali Indian author Amitav Ghosh about his haunting novel, The Shadow Lines.

A moving and thought-provoking meditation on the very real yet invisible lines, which divide nations, people, and families, The Shadow Lines focuses on a family in Calcutta and Dhaka and their connection with an English family in London.

From the tales of his colourful cousin the narrator conjures up a picture of London in his imagination that is so vivid that he recognizes it instantly when he visits years later and learns that real places can be invented inside your head.
