"Back to New York," he said, as one who enters a fog without a compass. "Back to fight pleosaurs, dinosaurs, and all kinds of monsters," he added, with a cheeriness which rang with the first false note she had heard from him. "I don't care," he concluded, and broke into a Spanish air, whose beat ran with the trickling hoof-beats of the ponies in the sand.

"That is it!" she thought. "That explains. He just does not care about anything."

Ahead, the lamps were beginning to twinkle in the little settlement which had sent such a contrast in citizenship as Mary Ewold and Pete Leddy out to the pass. They were approaching a single, isolated building, from the door of which came a spray of light and the sound of men's voices.

"That is Bill Lang's place," Mary explained. "He keeps a store, with a bar in the rear. He also has the post-office, thanks to his political influence, and this is where I have to stop for the mail when I return from the pass."

She had not spoken with any sense of a hint which it was inevitable he should accept.

"Let me get it for you;" and before she had time to protest, he had dismounted, drawing rein at the edge of the wooden steps.

She rode past where his pony was standing. When he entered the door, his tallness and lean ease of posture silhouetted in the light, she could look in on the group of idling male gossips.

"Don't!"

It was a half cry from her, hardly audible in an intensity which she knew was futile in the surge of her torturing self-incrimination. Why had she not thought that it would be here that Pete Leddy was bound to wait for anyone coming in by the trail from Galeria? The loungers suddenly dropped to the cover of boxes and barrels, as a flicker of steel shot upward, and behind the gleaming rim of a revolver muzzle held rigid was a brown hand and Leddy's hard, unyielding face.

What matter if the easy traveller could shoot? He was caught like a man coming out of an alley. He had no chance to draw in turn. In the click of a second-hand the thing would be over. Mary's eyes involuntarily closed, to avoid seeing the flash from the revolver. She listened for the report; for the fall of a body which should express the horror she had visualized for the hundredth time. A century seemed to pass and there was no sound except the beat of her heart, which ran in a cataract throb to her temples; no sound except that and what seemed to be soft, regular steps on the bare floor of the store.
