Tales of torture and abuse are the stuff of nightmares: this weekend a such a story is being retold, but this has, if not a happy, at least a hopeful, ending. The Macalester College theater department is presenting the world premiere of "Return to Kanburi" a remarkable story of how Eric Lomax, a British soldier tortured in by the Japanese during World War 2, found one of the men responsible decades later, and forgave him.
