The probate researchers investigate a competitive case based in Dorset, using the newly-released 1939 register to help unlock a family tree. Their search turns up an uncle of the deceased who was once a naval policeman and as they scour other censuses, they discover more and more hidden family members. In a second case, a retired publican and hotelier with a great love of bowls is found to have been born illegitimately north of the border in Scotland, complicating the heir hunter's search. Working the deceased's mother's side of the family only, research reveals an uncle who servied in Asia.
