Making a nearly one thousand mile journey from the Midlands, I've travelled to an unremarkable corner of north-western Poland to meet a remarkable young woman. Gryfice is a historic town just a few miles from the Baltic Sea, and it's home to Katarzyna Zablocka. At 25, Katarzyna has already suffered unimaginable pain in her life, but shown not just a determination to get to the truth, but an enduring love for the mother she lost so tragically.
