Johnny Vengeance — Frank Gruber

At fifteen he watched four men murder his father and mother. That day he knew what the rest of his life was going to be like. First he taught himself to draw faster than any man in the West. Then he set out, slowly, patiently, to track the killers. Johnny Vengeance knew he'd find them and make them remember that bloody day - and it would be the last memory they'd ever have.
