"Yes," she said, and was aware that her throat was suddenly parched. "You'll be careful, won't you, Phil?"
"Sure," he called back, as he put his horse at a canter to follow his friend up the draw.
The sound of the hoofs died away, and she was alone. That they were going to circle in and out among the tangle of hills until they were opposite the miscreant, she knew, but in spite of Brill's promise she had a heart of water. With trembling fingers she raised the glasses again, and focused them on that point which was to be the centre of the drama.
The man was moving about now, quite unconscious of the danger that menaced him. What she looked at was the great crime of Cattleland. All her life she had been taught to hold it in horror. But now something human in her was deeper than her detestation of the cowardly and awful thing this man had just done. She wanted to cry out to him a warning, and did in a faint, ineffective voice that carried not a tenth of the distance between them.
She had promised to remain where she was, but her tense interest in what was doing drew her forward in spite of herself. She rode along the ridge that bordered the park, at first slowly and then quicker as the impulse grew in her to be in at the finish.
The climax came. She saw him look round quickly, and in an instant his pony was at the gallop and he was lying low on its neck. A shot rang out, and another, but without checking his flight. He turned in the saddle and waved a derisive hand at the shooters, then plunged into a wash and disappeared.
What inspired her she could never tell. Perhaps it was her indignation at the thing he had done, perhaps her anger at that mocking wave of the hand with which he had vanished. She wheeled her horse, and put it at a canter down the nearest draw so as to try to intercept him at right angles. Her heart beat fast with excitement, but she was conscious of no fear.
Before she had covered half the distance, she knew she was going to be too late to cut off his retreat. Faintly, she heard the rhythm of hoofs striking the rocky bottom of the draw. Abruptly they ceased. Wondering what that could mean, she found her answer presently. For the pounding of the galloping broncho had renewed itself, and closer. The man was riding up the gulch toward her. He had turned into its mesquite-laced entrance for a hiding place. Phyllis drew rein, and waited quietly to confront him, but with a pulse that hammered the moments for her.
