To Die in Glory — Stuart G. Yates

Three men ride into the town of Glory and by the look of them, they are not coming to enjoy themselves.
Their meeting with the local sheriff can only have one outcome, and as the sheriff lies gunned down after an orgy of violence, the town is plunged into a nightmare of uncertainty and fear. What do the outlaws want, and why did they ruthlessly murder the sheriff?
Meanwhile, things are not going too well for Detective Simms. Having found love only to have it cruelly snatched away from him, his only way of facing the loss of Noreen is to seek solace from the bottom of a bottle. But soon his skills are called upon again, as he hears of a telegram sent from Glory, crying for help.
Promises will be broken and people will die. And in the end, Simms will have to use all his guile and experience to survive.
