Overview: The presenter visits the Dorset estate of Kingston Lacy, a country house with a vast collection of rare art, including an Egyptian obelisk which proved vital to the original deciphering of ancient hieroglyphics. The house also has a history of scandal involving its 19th-century owner William Bankes, who was forced to flee the country and live in exile - but is rumoured to have occasionally snuck back home. Plus, Alison Hammond meets the estate's herd of cows and Oz Clarke visits nearby Corfe Castle.
