It remains one of Ontario's enduring mysteries. On December 2, 1919, theatre magnate Ambrose Small completed a deal of a lifetime. After selling his Ontario-wide theatre network, Small banked $1 million and promised to be home for dinner - and then he disappeared from sight. No one confessed to a crime, his body never turned up, and leads went nowhere. The Agenda welcomes Toronto Star reporter Katie Daubs, who became fascinated with this story and chronicled it in her book, "The Missing Millionaire: The True Story of Ambrose Small and the City Obsessed with Finding Him."
