1929. Volume seven in the Northwest Series of books. The story begins: Sergeant John Dick, of the Royal Canadian Mounted Police, was leading his horse up a steep and rugged gorge in the great southwest region of Canada. It was close by the United States border, and practically in the shadow of the Rocky Mountains. A fine, military-looking figure, Sergeant Dick cut, in his scarlet tunic, riding-breeches, and Stetson or broad-brimmed, bell-crowned hat. He carried his rifle at the trail in his left hand, and had the bridle of his horse looped over his right arm.
