"They don't know," stammered Mona. "I wasn't sent, I came. Oh, granny, don't ask about it now—let me get indoors and sit down. I'm so tired I can't stand. I'll tell you all about it tomorrow."

But tired though she was, she turned back and thanked her rescuer. "I'd have been sleeping under a hedge to-night, if it hadn't been for you," she said gratefully.

"Oh, what I did isn't anything," he said amiably. "'Tisn't worth speaking about. I don't doubt but what you'd do as much for me, if I wanted it. Good night, Mrs. Barnes. Take care of yourself, ma'am, it's a bit fresh to-night. Good night, little maid. Gee-up, Nettle, my son."

What he had done was a mere nothing, as he said. But what he did do before the night was over was a very big something. Between two and three hours later he was in Seacombe, and knocking at Peter Carne's door.

"I knew you'd be anxious, so I thought I'd just step along and let 'ee know that your little maid's all right," he said quietly, making no mention of the seven long miles he had tramped after he had fed and stabled his horse for the night.

"Anxious!" Lucy lay half fainting in her chair. Peter's face was white and drawn with the anguish of the last few hours. Neither of them could doubt any longer that Mona had been swept off the rock and out to sea. Nothing else could have kept her, they thought. Patty and Philippa had told where they had last seen her, but it was four o'clock before they had come out of school and heard that she was missing. So the crowds clustering about the shore had never any hope of finding her alive.

Peter Carne almost fainted, too, with the relief the stranger's words brought him. The best he had dared to hope for when the knock came was the news that Mona's body had been washed in. The revulsion of feeling from despair to joy sent him reeling helpless into a chair.

Humphrey Dodds put out his arms and supported him gently. "I didn't know, I ought to have thought, and told 'ee more careful like."

"Where is she?" gasped Lucy.

"Safe with her grandmother—and there I'd let her bide for a bit, if I was you," he added, with a twinkle in his eye. "It'll do her good."
