She looked at him, while he was telling her of his interview with Hardyman, with an expression in her eyes which he had never seen in them before—an expression which set his heart beating wildly, and made him break off in his narrative before he had reached the end.

“I understand,” she said quietly, as he stopped in confusion. “You have made one more sacrifice to my welfare. Robert! I believe you are the noblest man that ever breathed the breath of life!”

His eyes sank before hers; he blushed like a boy. “I have done nothing for you yet,” he said. “Don’t despair of the future, if the pocketbook should not be found. I know who the man is who received the bank note; and I have only to find him to decide the question whether it is the stolen note or not.”

She smiled sadly as his enthusiasm. “Are you going back to Mr. Sharon to help you?” she asked. “That trick he played me has destroyed my belief in him. He no more knows than I do who the thief really is.”

“You are mistaken, Isabel. He knows—and I know.” He stopped there, and made a sign to her to be silent. One of the servants was approaching them.

“Is the pocketbook found?” Moody asked.

“No, sir.”

“Has Mr. Hardyman left the cottage?”

“He has just gone, sir. Have you any further instructions to give us?”

“No. There is my address in London, if the pocketbook should be found.”
