"No, I'm not hurt," she said slowly. "What does it mean? What has happened? Where is father?"

To this serious question Cragg dared not attempt at once to find an answer.

"Come a little way farther off," he said.

"That wall might go down too. Come this way. You're feeling queasy, aren't you?"

"Yes. I don't know where I am. I don't know what it means."

Pattie spoke slowly, like one bewildered. Then her eyes went to the ruined house, and recollection flashed up. Till then she had been stunned. A cry broke from her.

"Father! father! He was on the roof. Where is he?"

But for Cragg's detaining grasp she would have rushed to the edge of the depth. He caught her, and held her back by main force. She struggled fiercely, then fell back, senseless.

"Thank God for that!" muttered Cragg, tears in his eyes.
