Sweep of Fury by Dempsey Clay
Killer Jimmy Tucker wanted to die. 'Do It now, Gant,' he begged the stone-faced lawman. 'Don't let 'em swing me off their gallows. Just shoot me now!' He was pleading with the wrong man. The Marshals' Manual was Gant's bible. 'The law says you're to hang, Tucker,' he pronounced, 'and I'll see you do it.' 'You ain't human, Gant!' Gant nodded, Maybe Tucker was half-right but he'd still swing. The next badman to receive mercy from Marshal Gant would be the first.
