Paul Laidlaw and Claire Rawle set off on the final road trip leg from the Derbyshire town of Matlock.
Militaria mad Paul hopes a late 17th-century hand-forged halberd head earns him a huge profit. Claire buys a Chinese cloisonné vase and an Edwardian inkstand.
Paul also unravels the story behind the world-famous crooked church tower at Chesterfield and Claire meets a relative of the first man to circumnavigate Australia, who hails from the Lincolnshire town of Donnington.
Will Claire be the comeback kid and crush the mighty Laidlaw? The pressure is on at the final auction in Stamford, Lincolnshire.
