The Broken Gun
Begin with the massacre of twenty-seven innocent men. Follow it  with two brutal murders almost ninety years later. Add two curious,  hard-bitten veterans of guerrilla fighting and a beautiful,  terror-stricken girl. Mix with a pack of vicious killers who would have  been more than a match for the most notorious gunmen of the old West,  and you have Louis L'Amour' blistering novel of action and adventure in  the new West.
