John George Diefenbaker, or "the Dief", as his supporters called him, is known as one of Canada's most unforgettable and provocative Prime Ministers, serving as the country's 13th leader in the late 1950s and early 1960s, a volatile period of Canadian history. Diefenbaker's fiery campaign speeches and stinging political rebukes could strike fear in the hearts of opponents. During the early stages of his first term in government, he rode a huge wave of popularity. But the Dief was a political animal, a self-described lone wolf, and his obsession with politics eventually resulted in personal and career turmoil. Journalist Ernest Granson and historian, Arthur Milnes, explore this fascinating but perplexing character.
