Stolen Treasures

Three tales of stolen treasures: A hunt across two continents for the true owner of a Modigliani masterpiece that may have been looted by the Nazis during World War II. The first television interview with one of Canada’s most prolific art thieves, John Mark Tillmann -- he stole an estimated 10,000 items and the Mountie who tracked him down called him a “kleptomaniac with taste.” And on the frontlines with Canada’s little-known wildlife cops, who are tackling a $30 billion illegal trade in everything from reptile parts, plants, tusks and ivory.
