"I think so," said Quarles. "The Tibetans followed Mr. Ratcliffe to recover the lost eye, I have no doubt of that, and to be ready for any emergency had supplied themselves with a paste duplicate of the stone. Exactly how Mr. Ratcliffe died I can only conjecture. I remember that his eyes evidently saw something, and I fancy terror killed him. The Tibetans had undoubtedly watched him constantly, and had found out that he had the stone hidden in the boxes. Probably they expected to find it so hidden, having discovered that Mr. Ratcliffe had discarded the inner boxes of the talisman at the time of the robbery. Having made certain of this, I think that on the fatal night they made the curious sound that the idol makes when speaking, expecting that he would be listening for it, as their priests declared those who offended the god always did, and as a curious fact Mr. Ratcliffe actually was, remember; then possibly they thrust between the curtains one of those hideous masks which figure in so many religious ceremonies in Tibet. Mr. Ratcliffe was in a state of mind to give any sudden terror an enormous power over him, and I think he died without any violence being offered him. So the gem was recovered, the paste sapphire and the remaining boxes being left as a sign that the god had been avenged, a sign which I believe I have been able to read. There are the theory and some facts; you must make further inquiries yourself." The professor rose abruptly from his chair. Evidently he had no intention of answering questions, and he meant the interview to come to an end. "Thank you," I said. "I shall take steps at once to find out if you are correct." "For your own satisfaction, not mine," said Quarles; "I am certain. You asked how it was I came to Blenheim Square that morning. Chance! It is called that. I do not believe in chance. When I am impelled to do a thing, I do it because I recognize a directing will I am forced to obey. We live in a world girt with miracles, in an atmosphere of mystery which is beyond our comprehension. We find names for what we do not understand, psychic force, mind waves, telepathy, and the like, but they are only names and do not help us much. Keep an open mind, Mr. Wigan; you will be astonished what strange imaginings will enter it--imaginings which you will discover are real truths. An empty mind in an empty room, there you have the best receptacle for that great will which guides and governs all thought and action. I speak as a philosopher, and as an old man to a young one. Come to me if you like when you are in a difficulty, and I will help you if I am allowed to. Do you understand? Good-bye." * * * * *
