"You ain't goin' to try to stop him?" the boy said stupidly. "He was goin' to leave Tombstone at sundown. He'll be to the place before you ken ketch him, sure."

"We'll see," she answered shortly; "it is where the Huachuca road crosses, you are certain?"

He nodded forcibly. "Where all them mesquites is to one side, and the arroyo to the other. They'll be behind the mesquite. But you ain't goin' to head him off," he added, "there ain't even a short cut. The road's the shortest."

The stableman came on a run, leading her horse, and she fairly leaped down the steps, and slipping the pistol into the holster mounted with a spring. "All of you follow me," she said; "they are going to hold up Mr. Cairness."

On the instant she put her horse to a run and tore off through the gate toward the open country. It was dark, but by the stars she could see the road and its low bushes and big stones that danced by as her horse, with its belly to the ground, sped on. She strained her ears and caught the sound of hoofs. The men were following her, the gleam of her white dress guiding them. She knew they could not catch her. The horse she rode was a thoroughbred, the fastest on the ranch; not even Cairness's own could match it. It stretched out its long black neck and went evenly ahead, almost without motion, rising over a dog hole now and then, coming down again, and going on, unslacking. She felt the bit steadily and pressed her knee against the hunting horn for purchase, her toe barely touching the stirrup, that she might be the freer in a fall.

If it went like this, she thought, she might get to the cross-road first, and beyond. The four men would not matter much then, if she could but stop her husband. Why had he started back alone—and carrying money too? It was foolhardy. But then there was so little money, she knew, that he had probably not thought of it as booty. She turned her uncovered head and listened. Her hair had fallen loose and was streaming out in the wind. She could not hear the others now. They must be well behind.

There was a faint, white light above the distant mountains in the east. The moon was about to rise. In a few moments more it came drifting up, and the plain was all alight. Far away on the edge was a vague, half-luminous haze, and nearer the shadows of the bushes fell sharp and black. A mile ahead, perhaps, along the road, she could make out the dark blot of the mesquite clump. Behind, as she looked again, she could just see four figures following.

It occurred to her now for the first time that there was danger for herself, so far in front, so entirely alone. The chances for passing the mesquites were not very good. If the men were already there, and that might be counted upon, they would not let her pass if they could help it. It occasioned her but one fear—that she could not stop her husband. If she were to turn from the road out into the open, she would lose time, even if the horse did not fall, and time was not to be lost.

The mesquites were very near. She bent down over the horse's neck and spoke to him. His stride lengthened out yet more. She drew the little revolver, and cocked it, still bending low. If they were to fire at her, the white gown would make a good mark; but she would show as little of it as might be, and she would not waste time answering shots, if it could be helped.

The mesquites were directly ahead. A horseman came out from behind them and placed himself across the road. There was a sheen of moonlight on a revolver barrel and a shouted "Halt there!"
