In an exciting sequel to his last talk for us, our president now follows a spectacular branch of the Silk Road from the Caucasus across the Caspian Sea to Samarkand. He then turns south-east to explore the High Pamirs of Afghanistan – a region well-known to Marco Polo – before making a dramatic finale at the source of the Oxus in the heart of Central Asia. His stunning photos and entertaining and informative commentary make this a talk not to be missed.
