Slocum and the Gift Horse

Slocum's in a fistful of trouble with a deadly desperado.
Owen Surret earned his living doing dirty jobs for dangerous men. Then he went into business for himself, looting his employers of their ill-gotten gain, before murdering a rancher and rustling cattle. Pursued by the outlaws he betrayed, Surret is pulling up stakes and needs some cowboys to drive his herd to safer ground.
John Slocum has enough skills to join Surret's gang--but only long enough to generate heat with a blacksmith's daughter...and find a way to collect the bounty on the thieving killer's head...
