Dan Mahowny was a rising star at the Canadian Imperial Bank of Commerce. At twenty-four he was assistant manager of a major branch in the heart of Toronto's financial district. To his colleagues he was a workaholic. To his customers, he was astute, decisive and helpful. To his friends, he was a quiet, but humorous man who enjoyed watching sports on television. To his girlfriend, he was shy but engaging. None of them knew the other side of Dan Mahowny--the side that executed the largest single-handed bank fraud in Canadian history, grossing over $10 million in eighteen months to feed his gambling obsession.
