Episode 18

Raj Bisram and Catherine Southon reach the halfway point of their road trip. Starting in Suffolk, they are headed for an auction in Bourne, Lincolnshire. Catherine gets to the point with a propelling pencil, while Raj hopes to get ahead at auction with some 19th-century Italian hatpins. Detours around East Anglia give an opportunity for Catherine to learn how melons have helped to save millions of lives, while Raj meets an endangered horse with a significant history in these parts.
