To David Carrigan this interesting experience in his life might have covered an hour, a day, or a month. Or a year for that matter, for he seemed to have had an indefinite association with Pretty Eyes. He had known her for a long time and very intimately, it seemed. Yet he had no memory of the long fight in the hot sun, or of the river, or of the singing warblers, or of the inquisitive sandpiper that had marked out the line which his enemy's last bullet had traveled. He had entered into a new world in which everything was vague and unreal except that vision of dark hair, dark eyes, and pale, beautiful face. Several times he saw it with marvelous clearness, and each time he drifted away into darkness again with the sound of a voice growing fainter and fainter in his ears.

Then came a time of utter chaos and soundless gloom. He was in a pit, where even his subconscious self was almost dead under a crushing oppression. At last a star began to glimmer in this pit, a star pale and indistinct and a vast distance away. But it crept steadily up through the eternity of darkness, and the nearer it came, the less there was of the blackness of night. From a star it grew into a sun, and with the sun came dawn. In that dawn he heard the singing of a bird, and the bird was just over his head. When Carrigan opened his eyes, and understanding came to him, he found himself under the silver birch that belonged to the wood warbler.

For a space he did not ask himself how he had come there. He was looking at the river and the white strip of sand. Out there were the rock and his dunnage pack. Also his rifle. Instinctively his eyes turned to the balsam ambush farther down. That, too, was in a blaze of sunlight now. But where he lay, or sat, or stood—he was not sure what he was doing at that moment—it was shady and deliciously cool. The green of the cedar and spruce and balsam was close about him, inset with the silver and gold of the thickly-leaved birch. He discovered that he was bolstered up partly against the trunk of this birch and partly against a spruce sapling. Between these two, where his head rested, was a pile of soft moss freshly torn from the earth. And within reach of him was his own kit pail filled with water.

He moved himself cautiously and raised a hand to his head. His fingers came in contact with a bandage.

For a minute or two after that he sat without moving while his amazed senses seized upon the significance of it all. In the first place he was alive. But even this fact of living was less remarkable than the other things that had happened. He remembered the final moments of the unequal duel. His enemy had got him. And that enemy was a woman! Moreover, after she had blown away a part of his head and had him helpless in the sand, she had—in place of finishing him there—dragged him to this cool nook and tied up his wound. It was hard for him to believe, but the pail of water, the moss behind his shoulders, the bandage, and certain visions that were reforming themselves in his brain convinced him. A woman had shot him. She had worked like the very devil to kill him. And afterward she had saved him! He grinned. It was final proof that his mind hadn't been playing tricks on him. No one but a woman would have been quite so unreasonable. A man would have completed the job.

He began to look for her up and down the white strip of sand. And in looking he saw the gray and silver flash of the hard-working sandpiper. He chuckled, for he was exceedingly comfortable, and also exhilaratingly happy to know that the thing was over and he was not dead. If the sandpiper had been a man, he would have called him up to shake hands with him. For if it hadn't been for the bird getting squarely in front of him and giving him away, there might have been a more horrible end to it all. He shuddered as he thought of the mighty effort he had made to fire a shot into the heart of the balsam ambush—and perhaps into the heart of a woman!

He reached for the pail and drank deeply of the water in it. He felt no pain. His dizziness was gone. His mind had grown suddenly clear and alert. The warmth of the water told him almost instantly that it had been taken from the river some time ago. He observed the change in sun and shadows. With the instinct of a man trained to note details, he pulled out his watch. It was almost six o'clock. More than three hours had passed since the sandpiper had got in front of his gun. He did not attempt to rise to his feet, but scanned with slower and more careful scrutiny the edge of the forest and the river. He had been mystified while cringing for his life behind the rock, but he was infinitely more so now. Greater desire he had never had than this which thrilled him in these present minutes of his readjustment—desire to look upon the woman again. And then, all at once, there came back to him a mental flash of the other. He remembered, as if something was coming back to him out of a dream, how the whimsical twistings of his sick brain had made him see two faces instead of one. Yet he knew that the first picture of his mysterious assailant, the picture painted in his brain when he had tried to raise his pistol, was the right one. He had seen her dark eyes aglow; he had seen the sunlit sheen of her black hair rippling in the wind; he had seen the white pallor in her face, the slimness of her as she stood over him in horror—he remembered even the clutch of her white hand at her throat. A moment before she had tried to kill him. And then he had looked up and had seen her like that! It must have been some unaccountable trick in his brain that had flooded her hair with golden fire at times.

His eyes followed a furrow in the white sand which led from where he sat bolstered against the tree down to his pack and the rock. It was the trail made by his body when she had dragged him up to the shelter and coolness of the timber. One of his laws of physical care was to keep himself trained down to a hundred and sixty, but he wondered how she had dragged up even so much as that of dead weight. It had taken a great deal of effort. He could see distinctly three different places in the sand where she had stopped to rest.

Carrigan had earned a reputation as the expert analyst of "N" Division. In delicate matters it was seldom that McVane did not take him into consultation. He possessed an almost uncanny grip on the working processes of a criminal mind, and the first rule he had set down for himself was to regard the acts of omission rather than the one outstanding act of commission. But when he proved to himself that the chief actor in a drama possessed a normal rather than a criminal mind, he found himself in the position of checkmate. It was a thrilling game. And he was frankly puzzled now, until—one after another—he added up the sum total of what had been omitted in this instance of his own personal adventure. Hidden in her ambush, the woman who had shot him had been in both purpose and act an assassin. Her determination had been to kill him. She had disregarded the white flag with which he had pleaded for mercy. Her marksmanship was of fiendish cleverness. Up to her last shot she had been, to all intent and purpose, a murderess.

The change had come when she looked down upon him, bleeding and helpless, in the sand. Undoubtedly she had thought he was dying. But why, when she saw his eyes open a little later, had she cried out her gratitude to God? What had worked the sudden transformation in her? Why had she labored to save the life she had so atrociously coveted a minute before?
