Many knew this man as Sidney Reilly, but his real name was Sigmund Georgievich Rosenblum -- probably. Historians do know he was a British intelligence officer, and he’s considered the most accomplished spy in history. But, most of Reilly’s account of who he was and what he did was probably a lie. We can be certain of one thing; he was executed for treason, on the order of Joseph Stalin, leader of the Soviet Union.
