After twenty years of chasing renegades in the hostile Arizona and New Mexico terrtories, Conway Fargo headed east. Hoping to start a new life, he took a job in Chicago with the Pinkerton Agency. But the manner in which Fargo dealt with criminals was far too violent for eastern society. To keep him out of trouble, the Pinkerton Agency reassigned Fargo to guide two young, aristocratic couples and their Cherokee chaperone to the Navajo reservation. Unknown to Fargo, or to the Cherokee woman, the couples had no interest in the Navajo. Instead, they were secretly bound for Hawikuh, an ancient Zuni pueblo. In possesion of a map, the couples were seeking the lost treasure of Cibola, one of the Seven Cities of Gold sought in 1540 by the conquistador, Coronado. Unkown to the couples, however, Fargo was not the harmless middle-aged guide they assumed could be decieved. He was a man-hunter. The Apaches called him Tats-a-das-ago or Quick Killer. The whites called him The Parson. The Mexicans said he was the hand of God, a man they called Separado.
