Across Canada peace officers put their lives on the line every day. From John Fisk in 1804, the first known Canadian policeman killed in the line of duty, to the four RCMP officers shot to death in Mayerthorpe, Alberta, in 2005, renowned true crime writer Edward Butts takes a hard-hitting, compassionate, probing look at some of the stories involving the hundreds of Canadian law-enforcement officers who have found themselves in harm's way.

Some, like the four RCMP officers who perished in the Northwest Territories on the "Lost Patrol" of 1910, died in horrible accidents while performing their duties. Others, such as the Mounties involved in the manhunts for Almighty Voice and the Mad Trapper of Rat River, found themselves in extremely dangerous, violent situations.

One thing is certain about all of these peace officers: they displayed amazing courage and never hesitated to make the ultimate sacrifice for their fellow citizens.
