The Return of the Mucker
by Edgar Rice Burroughs
The wonderful story of an evil, hardened Chicago thug and Ruffian responds to the magical touch of great love, slowly changing his entire point of view, ethical norms and character from fear and hatred until he trusts the beautiful Barbara Harding, the daughter of a New York millionaire, and eventually falls in love with her. Eventually, believing that the gap between Grand Avenue and Riverside Drive was too wide for love to be overcome even by him, Billy refused to marry Barbara and left her. When the current story unfolds over the course of more than a year, it passes, and Byrne puts himself in more trouble in revolutionary Mexico.
