"I think you will find it very difficult to refuse to take it," said Calder. "I do not know Miss Eustace, but I can hazard a guess from the letters of hers which I have read to you. I do not think that she is a woman who will say 'yes' one day, and then because bad times come to you say 'no' the next, or allow you to say 'no' for her, either. I have a sort of notion that since she cares for you and you for her, you are doing little less than insulting her if you imagine that she cannot marry you and still be happy."

Durrance thought over that aspect of the question, and began to wonder. Calder might be right. Marriage with a blind man! It might, perhaps, be possible if upon both sides there was love, and the letter from Ethne proved—did it not?—that on both sides there was love. Besides, there were some trivial compensations which might help to make her sacrifice less burdensome. She could still live in her own country and move in her own home. For the Lennon house could be rebuilt and the estates cleared of their debt.

"Besides," said Calder, "there is always a possibility of a cure."

"There is no such possibility," said Durrance, with a decision which quite startled his companion. "You know that as well as I do;" and he added with a laugh, "You needn't start so guiltily. I haven't overheard a word of any of your conversations about me."

"Then what in the world makes you think that there's no chance?"

"The voice of every doctor who has encouraged me to hope. Their words—yes—their words tell me to visit specialists in Europe, and not lose heart, but their voices give the lie to their words. If one cannot see, one can at all events hear."

Calder looked thoughtfully at his friend. This was not the only occasion on which of late Durrance had surprised his friends by an unusual acuteness. Calder glanced uncomfortably at the letter which he was still holding in his hand.

"When was that letter written?" said Durrance, suddenly; and immediately upon the question he asked another, "What makes you jump?"

Calder laughed and explained hastily. "Why, I was looking at the letter at the moment when you asked, and your question came so pat that I could hardly believe you did not see what I was doing. It was written on the fifteenth of May."

"Ah," said Durrance, "the day I returned to Wadi Halfa blind."
