“I was afraid to ask,” said Frances.

He looked down at her. “You’re not afraid now. Shall I tell you everything?”

She met his look. “I know a good deal. I know about—Nan, and about your father,—at least in part.”

“You have got to know—everything,” he said, and stopped where he had stopped once before to gaze out between the Stones to the infinite distance. “And you are to understand, Frances, that what has passed between us now can be wiped out—as if it had never been, if you so desire it. You know about—my sister Nan.” His voice dropped. “I can’t talk about her even to you, except to tell you that you are somehow like her. That was what made my father take to you. He didn’t take to any strangers as a rule. Neither did I.” Again she was conscious of the close holding of his arm, but he did not turn his eyes towards her. He went sombrely on. “We gave up everything and came here because the trouble over Nan had turned his brain. He wanted to tear across the world and kill my cousin. So did I—once. But—my mother—well, you know my mother. You realized long ago that all we did was for her sake. And so—since so far as we knew, my father had only the one mania and was sane on all other points—we came here. Nan’s baby was born here. We settled down. My father never liked the life, but he got better. We hoped his brain was recovering. Then—one winter night—the madness broke out again. I was away on business. He got up in the early morning, went to Nan’s room, and ordered her out of the house with her child. He terrified her, and she went. The next morning she was found up by the Stones in deep snow, dead. The child was living, but she was always a weakling, and she lost her sight. My father had a seizure when he heard that Nan was dead. In his delirium he told them what he had done. But when he came to himself he had forgotten, and his distress over the loss of Nan was heart-rending. Of course he ought to have been sent away. My uncle, Theodore Rotherby, had urged it from the outset; but my poor mother would not hear of it. And I—well, I hadn’t the heart to insist. After that, I never left home again. Either Oliver or I kept guard day and night. But except for occasional outbursts of unreasonable anger he became much better, almost normal. He regarded me as his gaoler and hated me, but he always worshipped my mother. I believe it would have killed him to be parted from her. Better if it had perhaps, but—it’s too late now. What I did, I did for the best.” He uttered a heavy sigh. “It brutalized me. I couldn’t help it. It didn’t seem to matter. Nothing ever mattered till you came. I was harsh with the girls, I was harsh with everyone—except my mother. Life was so damnable. There were times when the burden seemed past bearing. The perpetual strain, year in, year out,—only God knows what it was.”

“I can guess,” whispered Frances.

His brooding eyes softened somewhat, but still he did not look at her. “Then you came. You changed everything. But that letter—you remember that lost letter? My father found it, recognized the writing, knew that my cousin was in the neighbourhood. That brought everything back. Somehow from the first he always connected you with Nan. There is a resemblance, though I can’t tell you where it lies. On the night my cousin came to meet you at the Stones—that ghastly night—he broke out. I think you know what happened. He tried to murder him, but he got away. Oliver was there, but he ought to have been earlier. I blamed him for that. The mischief might have been avoided. However, my cousin got away, and my father dodged us and came back to the house. There he left his gun, thinking he had killed his man. Then he must have seen the child. Possibly she spoke to him. I don’t know. But the lust for murder was on him that night. He followed her to the Stones, dodging us again, and saw her climb on to the Rocking Stone. He had made a great study of the Stones, and it was he who had discovered how to make the thing move. He used his knowledge on that occasion, and—and—well, you know what happened.” His arm tightened about her convulsively.

“Oh, don’t tell me any more!” Frances said.

He bit his lip and continued. “It all came out afterwards in his ravings, but we suspected foul play before. I was practically sure of it. Frances, it nearly killed my mother. I shall never forget her agony as long as I live.”

“My dear—my dear!” Frances said. But she was thinking of the man’s own agony which she had witnessed in the farm-kitchen on the night of little Ruth’s death.

He drew a hard breath between his teeth. “Then, as you know, he was taken ill. And I hoped he would die. My God! How I hoped he would die! That night with you in the garden—do you remember? The night you offered yourself to me! I could have fallen at your feet and worshipped you that night. But—I had to turn away. You understood, didn’t you? You knew?” A passionate note sounded in his voice.
