His Honor Newland Pontiff III, late of Exeter Territorial Prison, now presides over a vast tract of land with Cayuse Falls at its centre - a town he's confident he can transform into the 'Washington of the West.' But a demon from his past haunts the horizon and time is running short.Mason, vigilante hero to the downtrodden and mankiller, has come out of retirement to settle one last score - the only one that ever mattered - with a man who long ago forgot he'd wronged the famous 'killer of killers'. A tonic peddler, vengeful sisters, and a reluctant lawman all dog Mason's trail.But he vows that nothing will stop him from seeing this last mission through to its end even if he is not to survive.
