Charlie and Izzie continue their B-road romp, pointing their classic car towards Surrey. Gemologist Izzie finds a piece of jewellery that causes quite a stir at auction, while Charlie’s passion for furniture in all shades of brown sees him uncover a very rare table that sparks a frenzy of bids at the Dorking auction. Ditching the classic car, Charlie heads down river in a desperate attempt to keep eels swimming, while Izzie looks up to the sky in admiration of Britain’s first female astronomer.
