The launch of Brian Mulroney's volume of memoirs, from his boyhood in Baie Comeau, through his years in power as Prime Minister, was the publishing event of this year. But, in more than 1,000 comprehensive pages of anecdotes and information there is one notable name missing - Karlheinz Schreiber - the German dealmaker at the center of the darkest chapter of Mr. Mulroney's life. In Brian Mulroney: The Unauthorized Chapter, Linden MacIntyre and a fifth estate team report new revelations about the relationship between the two men as well as details about the attempt to cover the trail of the $300,000 the former Prime Minister received from Schreiber. Schreiber goes on the record to talk about a story from inside the world of Canadian politics.
