Hangman's noose

the long version

Freelance fighting man Carter O'Brien had five thousand reasons to go after the notorious Timberlake brothers. Each was a dollar bill. Isaac Parker, the "Hanging Judge" himself had asked O'Brien to track down the murderous outlaws, so he rode west into Indian territory, a vast and lawless land that was home to more than one owlhoot gang, and before long he was swapping lead with a man who wanted him dead, and whiskey with a lady desperado called Belle Starr.
