Martin is off to visit his brother, Tim, to see if he can shed any light on the life of their Grandfather.
When he was just 10 years old, Martin Freeman's father died of a heart attack. As a child, the actor tried to show people that he was a "brave little four-foot thunderball". "I've only realised how tough it is as I've got older," he says.
The early loss of his father had another effect: Martin knows "embarrassingly little" about his dad's side of the family. To fill in the gaps, Martin begins by researching the life of his grandfather, Leonard.
