Chumley and Rodgers venture to Yates Castle in Suffolk. The castle is the former home of the Chumley family, but was lost in a card game by Sir Bernard's great-great grandfather. It is now owned by Dame Lily Yates (David Foxxe). Tony tries to discover the whereabouts of the Golden Potato from Lily, while Sir Bernard seeks revenge by attempting to burn it down the house by setting fire to Lily's bedroom.
