Rim Fannin would have done just about anything to prove that John Romaine, the owner of White Mountain Freight, was the traitor responsible for his father's death. So when he got word in the sooty blackness of a Tucson alley that twenty heavily guarded White Mountain wagons were traveling by night toward Tubac, Rim signed on as a mule skinner. He wasn't very good with a mule whip but he managed ... until his train was attacked by Indians and he was captured. Rim knew escape was hopeless when his captors took him to Canyon de Chelly. And late one night when the Bear Clan held a fire dance in the shadow of Spider Rock, he realized why he had been taken alive....Rim Fannin sets out to prove one man is the traitor responsible for his father's death, only to be captured by Indians.
