"Why does he think that I shall go to San Stefano?" he asked himself. "What is San Stefano to me? Why should I meet him there?"

He sat down again, holding the flower loosely in one hand, and resting his head upon the other. The old langour and sickness of heart were coming back upon him; the momentary excitement had passed away. He would have given a great deal to be able to rouse himself from the depression which had taken such firm hold of his mind; but he failed to discover any means of doing so. He had a vague, morbid fancy that Brother Dino could help him to master his own trouble—he knew not how; but this hope had failed him. He did not even care to go to San Stefano.

After a little time he remembered the letter in his pocket, addressed to him in Mr. Colquhoun's handwriting. He took it out and looked at it for a few minutes. Why should Mr. Colquhoun write to him unless he had something unpleasant to say? Perhaps he was only forwarding some letters. This quiet, grassy quadrangle was a good place in which to read letters, he thought. He would open the envelope and see what Colquhoun had to say.

He opened it very slowly.

Then he started, and his hand began to tremble. The only letter enclosed was one in his mother's handwriting. Upon a slip of blue paper were a few words from the lawyer. "Forwarded to Mr. Brian Luttrell at Mrs. Luttrell's request on the 25th of October, 1877, by James Colquhoun."

Brian opened the letter. It had no formal opening, but it was carefully signed and dated, and ran as follows:—

"They tell me that I have done you an injury by doubting your word, and that I am an unnatural mother in saying—even in my own chamber—what I thought. I have an excuse, which no one knows but myself and James Colquhoun. I think it is well under present circumstances to tell you what it is.

"I am a strong believer in race. I think that the influence of blood is far more powerful than those of training or education, how strong soever they may be. Therefore, I was never astonished although I was grieved, to see that your love for Richard was not so great as that of brothers should have been——"

"It is false!" said Brian, with a groan, crushing the letter in his hand, and letting it fall to his side. "No brother could have loved Richard more than I."

Presently he took up the letter again and read.
