Blast to oblivion

the long version

Zach Skann came to Denver toting a deadly 12-gauge Greener shotgun. His mind was warped and sick from fifteen years in a penitentiary and it sought the palliative of vengeance against mines investor Ryan Bennett, the former Pinkerton detective responsible for his incarceration and the hangings of comrades. Subsequently, it fell to Joshua Dillard, gun-for-hire, to seek the truth about Bennett's murder for his sister, icily beautiful Flora Bennett. She declared she'd been cheated of a bequest; that Ryan's widow and his smooth ex-secretary knew more than they were letting on. To clear up the sorry mess of accusation and trickery, Joshua rode to a mining-town hell-hole. There the trail of inquiry became a trail of more blood!
