Hal, Mercedes and Charles

Hal, Mercedes and Charles are one of the main antagonists of Jack London's 1903 short adventure novel The Call of the Wild. They are gold seekers who buy Buck and his team and try to drive them, but their inexperience makes them terrible masters, as they run out of food during the journey and bicker among themselves. The trio are meant to represent the weakness of overcivilized men and to embody the man-dog relationship at its worst.

Background
Buck's next owners are a trio of stampeders (Hal, Charles, and a woman named Mercedes from the United States), who are inexperienced at surviving in the Northern wilderness. They struggle to control the sled and ignore warnings that the spring melt poses dangers. They overfeed the dogs and then starve them when the food runs out. On their journey they meet John Thornton, an experienced outdoorsman, who notices the dogs have been poorly treated and are in a weakened condition. He warns the trio against crossing the river, but they ignore his advice and order Buck to move on. Exhausted, starving, and sensing the danger ahead, Buck refuses and continues to lie unmoving in the snow. After Buck is beaten by Hal, Thornton recognizes him to be a remarkable dog. Disgusted by the driver's treatment of Buck, Thornton hits Hal with the butt of his axe, cuts Buck free from his traces, and tells the trio he is keeping him, much to Hal's displeasure. After some argument, the trio leaves and tries to cross the river, but as Thornton warned, the ice breaks, and the three fall into the river and drown, along with the sled and neglected dogs.
