From the pageantry of the Musical Ride to the movie- star good looks of the fictional Dudley Do- Right, the image of the handsome and stalwart Mountie has long been a part of popular North American culture. But there's much more to being a member of the Royal Canadian Mounted Police than wearing a red coat. It's an important career in law enforcement and public service. In M is for Mountie: An RCMP Alphabet, award- winning author Polly Horvath explains the proud traditions and important work of the Royal Canadian Mounted Police.
