Flog it! comes from Highcliffe Castle in Dorset, which is built from the ruins of several French great houses. Christina Trevanion and Adam Partridge pick out some gems to take to auction, among them an art deco diamond watch and a Newlyn copper teapot. Other finds include some Isle of Wight glass and postcards by 20th-century manufacturer Tucks. Presenter Paul Martin explores the incredible salvage store in the castle and hears the extraordinary story of a wheeler-dealer Victorian collector in Bournemouth.
