Death Rides Alone — Dale Graham

When Bronco Travis rides into the mining town of Silverton in Colorado Territory, his only thought is to avenge the death of his father. Nobody recognises the young son of the part-time marshal who had been brutally murdered eight years before by Jack Bowdrie and his gang. It appeared straightforward enough: just slip into town and get the job done. But Bowdrie has taken over the town and has no intention of being ousted from his profitable roost. So when the bodies begin to pile up, the gang boss takes swift action that almost ends in Bronco's own demise. He will need all his wits and a lethal gun-hand if his deadly nemesis is to be defeated.
