Antiques Roadshow: Walmer Castle 1

The Antiques Roadshow arrives in Walmer Castle near Deal. There are surprises in store for a woman who has always believed that her mother's ring contained a large topaz stone, and the owner of a rare Wemyss piglet, casually kept on a windowsill. A table with a secret compartment intrigues furniture expert Lennox Cato, while books specialist Justin Croft is enthralled by the story of the first recorded man to swim the channel in 1875. Other curiosities include the diary of a British prisoner of war held captive in Germany, and a beautiful set of French fashion illustrations from the 1920s. Rare objects include a table clock by renowned 17th-century maker Daniel Quare, and a showstopping collection of Martin Brothers pottery. Andy McConnell challenges Fiona to spot the impostor amongst a collection of Roemer glasses, only one of which is a genuine 18th-century piece.
