“Not deliberately,” my companion replied. “But I believe it was through some human agency that she was blinded. I think some person or persons were anxious that Miss McLeod should remain blind, in case we should, in the process of recovering her sight, hit upon the cause of her losing it.”

“Mr. Garnesk,” I said presently, “you are bringing a very terrible charge against some human monster whom we have yet to discover. But I must admit that you seem to have logic on your side. It remains for me to discover who these people are—if there are more than one.”

“Yes,” he mused; “that is what we must discover.”

“We!” I exclaimed. “Then you’re not going away?”

“Yes,” he said. “I think it would be fairer to you all if I left you. I think my arrival has done some good—my departure may do more. But I assure you, Mr. Ewart, I shall not give up this case till Miss McLeod recovers her sight. I give you my hand on that.”

I shook hands with him warmly.

“But I don’t even know that!” I cried, forgetting Dennis for the moment. As for Olvery, he had gone clean out of my mind. “Who do you mean?”
