“Has no one learned to use these weapons?”

“No,” Naida answered. “The Duca kept them for himself.”

“We think,” put in Ivana, “that he hoped to learn to use them, and was afraid for us to have the knowledge.”

Kirby filled one of the magazines, and felt the heft of the gun with pleasure.

“Very well,” he said. “It looks to me as though your time to learn the art of shooting has come at last. Come, I think we had better be getting back downstairs.”

Kirby took three guns himself, and with the others lugging the rest, they started back. The parchment rolls, he decided, must be left for examination later on.

They were all elated when they rejoined the girls in the prayer chamber, and high spirits were still further increased by the report, promptly given, that all had remained quiet in the amphitheatre. Save only for the presence of Elana, radiant and calm in death, the give and take of questions would have been accompanied by actual gaiety.

But the time of peace did not last much longer. While Naida was in the midst of answering incessant questions about the wonders of the jewel chamber, Kirby heard a sound from below, and suddenly went over to the downward-winding steps.

“Listen,” he called sharply back to the others.

He had not been mistaken. Many footsteps echoed from the amphitheatre, and he made out that the caciques were coming toward the bolted gate at the foot of the steps. While he listened, and Naida came eagerly to his side, silence fell.
