Auctioneer Izzie Balmer and jewellery expert Ishy Khan explore the county of Yorkshire, pointing their vintage golden Volvo towards the likes of Knaresborough, York and Harrogate, before heading south for their third auction. They also discover an awful lot of fascinating history along the way, including a trip to a spa and the little-known story of a woman who played a part in setting up some 200 schools around the world
