Ambrose Small, a 53-year-old Canadian theatre magnate, disappeared from Toronto on the afternoon of December 2, 1919, after depositing a cheque for one million dollars with his wife, Theresa. He had sold his theatre holdings for $1.7 million the day before and was last seen at about 5:30 p.m. in his office in the Grand Opera House by his lawyer, F. W. M. Flock. His absence was not reported for weeks because he sometimes disappeared for affairs; police were alerted in January 1920.

Investigators interviewed many people, including Small’s mistress, his wife Theresa, and his secretary John Jack Doughty. Doughty briefly vanished with bonds but was later found and not tied to Small’s disappearance. A purported confession from someone named Reuter claimed Small’s body had been burned in the Grand Opera House furnace, but no body or conclusive evidence ever emerged. A 1936 re-investigation suggested possible murder by his wife, and the case remained open through the 1960s before the Toronto police closed it in 1960; Small was declared dead in absentia in 1923. Who has information about Ambrose Small’s final movements in Toronto that December afternoon?
