Last month, I received a letter from a Swedish woman. She had seen an old news film shot in 1980, in which I had reported from the frontline of the Iran/Iraq war. She said my team had filmed a man, who then had been a young Iranian soldier languishing in an Iraqi prisoner of war camp, but who today, 40 years on, is her husband and the father of their two children. So we decided to visit him in Stockholm. How had a man who had suffered 13 years as a POW in Iraq somehow found his way to life and love in Sweden?
