“And his mother?”

“Yes, and his mother.”

The old man’s voice assumed almost a kindly tone.

“He is, indeed, a friend of my family,” thought Mr. Bixby; and then he started, for fear he might have spoken aloud.

His eyes fell upon the packet of letters. He must read them. He must end the interview. The old doctor must have noticed Mr. Bixby’s eyes, with the tears rising in them, as he tenderly touched the letters one by one, for it was with a voice very gentle and low that he spoke again.

“I attended once a very dear friend of his. It must be quite ten years ago now. Her name was Margaret. I think she loved him, for I remember—yes—it was one Christmas-eve, she said, and after that she said no more, ‘Has Harry come?’”

Mr. Bixby could bear no more. His sobs were striving for utterance. His fingers grasped the strong oak arms of his chair. It was only the thought of the letters which gave him strength to say:

“I am sorry, sir. You mistake me. I must ask you to leave me. You may come again. I shall be here, but I have something I would do to-night. I have given you much of my time. It is already late.”

“It is you who mistake, Mr. Bangs. But I am going now. I said I would stop but a moment. I have kept my promise, as you will see by your clock.”
