Series following the work of probate researchers as they search for heirs of people who have died without leaving a will and left thousands of pounds unclaimed.
Avid cricket fan Cecil Walton died in Durham in 2010 leaving no will. It's now up to the heir hunters to find relatives who can inherit his estimated £100,000 estate.
The Heir Hunters also look at the case of Gustav Sturm a German who came to Britain as a prisoner of war and never left. Gustav's family knew little of how he had been forced to fight for the German army in some of the bloodiest battles of World War II. Plus, details of three unsolved cases. Could you be an heir to an unclaimed estate worth thousands or even millions of pounds?
