Yevgeni Vladimirovich Brik and James Douglas Finley Morrison were central figures in what was considered one of the most important Cold War operations in the West at the time. Their story, which involves espionage, intelligence tradecraft, intelligence service penetrations, double agent scenarios, and betrayal, is a piece of Cold War intelligence history that has never been fully told. Yevgeni Brik was a KGB deep cover illegal who had been dispatched to Canada in 1951. He settled in Verdun, Quebec. He eventually became the KGB Illegal Resident where he had responsibility for running a number of agents, one of whom was working on the CF-105, Avro Arrow. In 1953, he fell in love with a married Canadian woman to whom he revealed his true identity. She persuaded him to turn himself in, which resulted in his becoming a double agent, working for Canada. He was later betrayed by a Royal Canadian Mounted Police Officer, James Morrison, who sought money from the KGB to pay his debts. Brik was consequently lured back to Moscow in 1955, where he was arrested, and interrogated. Convicted of treason, a traitor s fate awaited him, predictable, grim and final. Incredibly, he reappeared at a British Embassy as an old man in 1992, seeking Canada s help. He was exfiltrated by a joint Canadian British intelligence team which was headed by Donald Mahar. He was debriefed by Mahar for several months when they returned to Canada. and "
