The story describes the recent uprising along the border, and ends with the finding of the gold which two prospectors had willed to the girl who is the story's heroine. When young Richard Gale arrived in the Southwestern border town of Casita, he didn't realize it was a tinderbox waiting to explode. There's a revolution in Mexico and American troops are stationed along the border. The town itself is overrun by bandits and renegades. And things only get worse for Gale when he promises to help protect the daughter of a murdered Spanish aristocrat. The bandit leader who killed the girl's father wants her found-right away-and he'll destroy anyone who tries to stop him. A FACE haunted Cameron-a woman's face. It was there in the white heart of the dying campfire; it hung in the shadows that hovered over the flickering light; it drifted in the darkness beyond. This hour, when the day had closed and the lonely desert night set in with its dead silence, was one in which Cameron's mind was thronged with memories of a time long past-of a home back in Peoria, of a woman he had wronged and lost, and loved too late. He was a prospector for gold, a hunter of solitude, a lover of the drear, rock-ribbed infinitude, because he wanted to be alone to remember. A sound disturbed Cameron's reflections. He bent his head listening. A soft wind fanned the paling embers, blew sparks and white ashes and thin smoke away into the enshrouding circle of blackness. His burro did not appear to be moving about. The quiet split to the cry of a coyote. It rose strange, wild, mournful-not the howl of a prowling upland beast baying the campfire or barking at a lonely prospector, but the wail of a wolf, full-voiced, crying out the meaning of the desert and the night. Hunger throbbed in it-hunger for a mate, for offspring, for life. When it ceased, the terrible desert silence smote Cameron, and the cry echoed in his soul. He and that wandering wolf were brothers. Then a sharp clink of metal on stone and soft pads of hoofs in sand prompted Cameron to reach for his gun, and to move out of the light of the waning campfire. He was somewhere along the wild border line between Sonora and Arizona; and the prospector who dared the heat and barrenness of that region risked other dangers sometimes as menacing.
