The Return of the Mucker - The Mucker spent his life fighting. He fought his way out of the worst of Chicago's slums, he fought his way out of a jail sentence for a murder he didn't commit. Then, forced to fight for his freedom, destiny led him through a startling series of further adventures to Mexico -- and a fight for his life in the middle of a bloody revolution. Like two thieves they crept along in the shadow of the canyon wall. Inwardly Billy cursed the darkness of the night which hid from view everything more than a few paces from them. Yet it might have been this very darkness which would help save them, since it hid them as effectually from an enemy as it hid the enemy from them.
