Slocum Down Mexico Way (Hardcover, Turtleback School & Library ed.)

Slocum hooks up with a lovely widow in a town bullied by bandits whose leader uses peasants as slave labor, takes any woman he wants, and tortures and kills anyone who displeases him. Slocum's going to show that it's one thing to push around harmless country folk--and another to face a tough pistolero who's shooting back. Original.
