Most of the nation's greatest works of art are in our museums and galleries, but there are also thousands of significant works – some valuable, some not - in homes across the country.

BBC Arts Editor Will Gompertz discovers extraordinary stories behind the art-works on our domestic walls or shelves, and the tales they tell about our nation - an unwritten biography charting ups and downs, highs and lows.

In this edition, Will looks at art passed from fathers to sons. Many art-works - and the tales behind them - are handed down in this way, and the programme includes the story of how Luke, son of celebrated artist Mark Gertler, began to understand his father's life through the art he now owns.
