The Vigilante and the Regulator — Ray Hogan

THE REGULATOR
William Thompson was famous for clearing out rustlers from the range, so they summoned him to Oklahoma to clean up the No Man's Land of the Panhandle. He was warned to stay on the right side of the law in carrying out his duties - hard to do in the deadly territory that was the hide-out for cattle rustlers, horse thieves, and other desperadoes. But nothing was going to stop Bill Thompson from getting the job done . . .

Ex-lawman Jake Harper was railroaded by a gang who murdered a miner and his wife and stole a fortune in gold. By trickery and "buying off" the authorities, the outlaws went free and Harper went to prison. Later pardoned, he sets out to track down the killers and make them pay. But a crooked U.S. marshal tries to thwart Harper's pursuit, hoping to see him once more behind bars.
