A new series starting on the BBC, presented by the excitable Dan Cruickshank, looks at some of the finest homes in 'The Country House Revealed - A Secret History of the British Ancestral Home'. The series promises a look behind the estate wall at some homes which have never been open to the public, giving us a rare chance to glimpse houses which enjoy secure, well-funded ownership and demonstrating that the fears of those who thought these houses would never be sustainable have been thankfully proved wrong.
