"An explosive!" Zenas Wright almost shouted the words. "You have a brain in that red head, my boy. With the proper chemicals it might be done." He clapped Everson on the shoulder. "With you to help me, it might be done. What do you think, lieutenant?"

"I would do most anything to get a chance at this nest of devils," said Everson, and his eyes glittered. "I have not trusted this man. I do not know that I trust him now. But if he is playing fair, there seems no other way. Whatever you decide to do, I am with you, and will do my best. If we can find the chemicals, we can make an explosive powerful enough to move a few tons of stone, if that will do any good."

"Break you the wall, and I will promise you the rest of the trick," the captain cried, "or Ruthar will die to the last man on the road to Adlaz!"

He considered for a moment.

"One man I can surely take with me to Ruthar," he said. "Two will double, aye more than double the risk; and three would more than triple it. Still, it may be accomplished. I must have a little time; but I will do my best.

"Now, my brother, what say you? If I can bring it about so that you and the old man here, Father Zenas, and this other, who, though he trust me not, I will yet play fair by—if I can manage it that these go with me to Ruthar—will you come, also?"

"What of these others?" Polaris asked, and looked at Rose Emer.

"Here they must stay," Oleric answered.

"'Twill be hard enough to take the three of you—and slaying will be done before it is accomplished. It is impossible to take more. By the way which we shall go, no woman might pass undetected. But I tell you they shall come to no harm in your absence. The very law of the land protects them. They be marked for the ceremonies of Shamar. Until the appointed time, not even the king himself dare harm them. Bethink you, brother; this is the only way."

"Yonder on the ship you made a promise, Oleric," replied Polaris. "I think you will try to keep it. I trust you. But there are other things to consider." He addressed himself to Rose Emer.
