Claudia Cornwall, born in the International Settlement of Shanghai, came to Canada with her parents in 1949 and was baptized as an Anglican. At the age of forty she wrote to an uncle in Vienna seeking childhood photos of her father. Her uncle sent a photo of her young father in a garden with two women, and an accompanying letter which casually mentioned that "the woman standing up was our mother, who died in concentration camp." Shaken, Cornwall set out to unearth her family's buried Jewish heritage. ..

In 1939, as the Nazis closed in, Alfred Berger mailed a desperate letter to an American stranger who happened to share his last name. He and his wife, Viennese Jews, had found escape routes for their daughters. But now their money, connections, and emotional energy were nearly exhausted. Alfred begged the American recipient of the letter, “You are surely informed about the situation of all Jews in Central Europe.... By pure chance I got your address.... My daughter and her husband will go... to America.... Help us to follow our children.... It is our last and only hope....” After languishing in a California attic for decades, Alfred’s letter ended up in the hands of Faris Cassell, a journalist who couldn’t rest until she discovered the ending of the story. Traveling across the United States as well as to Austria, the Czech Republic, Belarus, and Israel, she uncovered an extraordinary story of heart-wrenching loss and unforgettable love that endures to this day. Did the Bergers’ desperate letter find a response? Did they—and their daughters—survive? Did they leave living descendants? You will find the answers here. A story that will move any reader, The Unanswered Letter is a poignant reminder that love and hope never die.
