Blue Pete and his pinto pony, Whiskers, could choose their employer on any of the ranches of the west; they were the best team available, knowledgeable and hard working.
Blue Pete found a good friend in Corporal Mahon, his young Mountie friend. And Mahon had his problems with criminals in the area, leading to Blue Pete's trials.
This friendship, and Blue Pete's adventures lasted for about 25 novels.
Blue Pete: Half Breed is the first of those adventures.
