Kenneth Wren lived all his life in Romford, and when he passed away aged 79 he appeared to have no remaining family. Despite having lived in sheltered accommodation for nearly 16 years, even his neighbours knew nothing about him. As the heir hunters at Fraser and Fraser set to work they discover that Kenneth was once part of a very large family struggling to survive the inter-war years. But why did he lose touch? And with such a big family, surely there must be at least one surviving heir? Fraser and Fraser is also on the case of Jan Olszewski. A Polish emigrant living in Halifax, Jan died in 1998 leaving an estate of 53,000 pounds. As the trail leads back to Poland, a tale emerges of wartime heroism, the systematic carving up of a country and the shocking truth behind the notorious Katyn massacre of 1940. But will the team succeed in tracking down Jan's family? And how will any heirs react to hearing that he survived the war and started a whole new life for himself in England?
