Holly Morris takes over the journey in Central Asia, where silk was traded for "flying horses" from the fertile Ferghana Valley. Crossing the Jiptik Pass to Osh, she then explores the ancient Kingdom of Samarkand and Bukhara before crossing the stony desert of Turkmenistan to the lost city of Merv. Then it's on to the modern capital of Baku in oil-rich Azerbaijan, her last stop before reaching the caravanserais of Turkey and finally the rich bazaars of Istanbul.
