The heir hunters are on the trail of families entitled to the estates of people who have died without a will. Often that can mean a windfall of thousands of pounds.

Ronald Millar died aged 80. After a shocking incident four years before his death, Ronald became a recluse, his only contact with the outside world coming through volunteers who helped him with shopping. But he left behind an estate worth £30,000, and the Fraser team is soon in a race against time to find any descendants.

At Heirtrace in Suffolk, Derek Rodbard is working to trace the descendants of people killed during the Holocaust - the systematic genocide of the Jews by the Nazis. Focusing on Ernst Hornung, a Jewish professional who was killed leaving a still-unpaid life insurance policy, he soon discovers a son, Otto. But for Otto, the money is of secondary importance.

As Derek delves deeper, a tale emerges of incredible courage and tenacity, of a family determined to maintain its unity despite being torn apart by events, and of a Swedish diplomat's extraordinary efforts to save the lives of 100,000 people. Show less
