“And then you saw Olvery?” he asked. “What did he say?”

I got up, paced the room. What had Olvery said? Should I ever forget those blistering words to the day of my death?

“Come, old boy,” said Dennis kindly. “You must remember that Olvery is merely a man. He is only one of the many floundering about among the mysteries of Nature, trying to throw light upon darkness. You mustn’t imagine that his view is necessarily correct, from whichever point he looked at the case.”

“Thank you for that,” I said. “I am afraid I forgot that he might possibly be mistaken. He says he knows nothing of this case at all; he can make nothing of it; it is quite beyond him. He is certain that no such similar case has been brought to the knowledge of optical science. His view is that there is the remotest possibility that this green veil may lift, but he says he is sure that if there were any scientific reason for saying that her sight will be restored he would be able to detect it.”

“I prefer your Dr. Whitehouse to this man any day,” said Dennis emphatically. “He took just the opposite view. This man Olvery, like so many specialists, is evidently a dogmatic egotist.”

“I’m very glad you can give us even that hope. But the eyes are such a delicate instrument. It is difficult to see how the sight can be recovered when once it has gone. Of course, Olvery is going to do what he can. He has suggested certain treatment, and massage, and so forth, and he has no objection to her going back home again. Myra, of course, is tremendously anxious for me to take her back to her father. She is worrying about him already; and, fortunately, Olvery knows Whitehouse, and has the highest opinion of him.”

“Go back as soon as you can, old chap,” Dennis advised. “Wire me if there is anything I can do for you at this end. I’ll make some inquiries, and see if I can find out anything about any similar cases, and so on. But you take the girl back home if she wants to go.”

While we were still talking, Dennis’s man, Cooper, entered.
