Fiona Bruce and the team visit Hatfield House in Hertfordshire. Amongst the objects exciting the experts are a collection of almost 500 ornamental pigs, doll's house furniture made out of shell cases from the Somme in World War One, and three small tiles salvaged by a builder, which turn out to be worth a fortune. Meanwhile, Fiona takes a spin in the car that stars in the programme's opening sequence - the classic Daimler Dart.
