Cyril laid his calm hand on his brother's restless one, and led him off towards the plateau.

"Do nothing, Richard. You are hasty and incautious. They cannot make any discovery."

"And that fellow talking of going to sound the rocks, with his boasted engineering experience?"

"Let him go. If the square sounds as hollow as his head, what then? They can make nothing else of it. No discovery can be made from the outside; you know it can not; and care must be taken that they don't get in."

"Perhaps you would not care if they did," spoke Richard in his unjust passion.

"You know better," said Cyril, sadly. "However I may have wished that certain circumstances did not exist, I would so far act with you now as to ward off discovery. I would give my life, Richard, to avert pain from you all, and disgrace from the Red Court's good name. Believe me, nothing bad will come of this, if you are only cautious. But your temper is enough to ruin all--to set Hunter's suspicions on you. You should have treated it derisively, jokingly, as I did."

Richard, never brooking interference, despising all advice, flung Cyril's arm aside, and turned off swearing, meeting Isaac, who was coming round by the plateau.

"Isaac, we are dropped upon."

"What?"

"We are dropped upon, I say."
