Chavis halted, his face a dirty, chalkish white. Twice his lips opened, in astonishment or fear, she could not tell which, but no sound came from them. He stood silent, watching her, furtive-eyed, crouching.

In this interval her thoughts rioted in chaos, like dust before a hurricane. But a question dominated all: could she carry out her threat to kill Chavis, if he took the step?

She knew she would. For in this crisis she had discovered one of nature’s first laws. She had never understood, before, but in the last few minutes knowledge had come to her like a burst of light in the darkness. And a voice came to her also—Randerson’s; she mentally repeated the words he had spoken on the day he had told her about the rustlers: “I reckon you’d fight like a tiger, ma’am, if the time ever come when you had to.”

Yes, she would fight. Not as a tiger would fight, but as Randerson himself had fought—not with a lust to do murder, but in self-protection. And in this instant the spirit of Randerson seemed to stand beside her, applauding her, seeming to whisper words of encouragement to her. And she caught something of his manner when danger threatened; his cold deliberation, his steadiness of hand and eye, his grim alertness. For she had unconsciously studied him in the few minutes preceding the death of Pickett, and she was as unconsciously imitating him now.

Her thoughts ceased, however, when she saw Chavis grin at her, mockingly.

“It’s a bluff!” he said. “You couldn’t hit the ground, if you had a-hold of the gun with both hands!” He moved slightly, measuring the distance between them.

Plainly, she saw from his actions, from his tensed muscles, her threat would not stop him. She was very pale, and her breast heaved as though from a hard run; Chavis could hear the sound of her breathing as he set himself for a leap; but her lips were pressed tightly together, her eyes glowed and widened as she followed the man’s movements. She was going to kill; she had steeled her mind to that. And when she saw the man’s muscles contract for the rush that he hoped would disconcert her, she fired, coolly and deliberately.

With the deafening roar of the weapon in her ears, a revulsion, swift, sickening, overcame her. The report reverberated hideously; she seemed to hear a thousand of them. And the smoke billowed around her, strong, pungent. Through it she saw Chavis stagger, clap one hand to his chest and tumble headlong, face down, at her feet. The interior of the cabin whirled in mad circles; the floor seemed to be rising to meet her, and she sank to it, the six-shooter striking the bare boards with a thud that sounded to her like a peal of thunder. And then oblivion, deep and welcome, descended.

Coming down through the break in the canyon, riding slightly in advance of Hagar, Randerson heard the report of a pistol, distant and muffled. He turned in the saddle and looked at Hagar questioningly.

“That come from your shack!” he said shortly; “Ruth there alone?”
