The flat ground ended abruptly, and they had to climb down jagged rocks. Lucia thought that her chance of escape had come, but the Austrian never lessened his hold on her arm.

They had traveled this far without meeting any one. The only signs of life had been the mysterious noise underground, and the click of Garibaldi's sharp hoofs as they hit the stone.

When they reached a certain point the soldier stopped. "If you make any noise," he said roughly, "I will have to shoot you."

Lucia opened her mouth to scream, but before the sound came she changed her mind. A new and splendid idea had just come to her. She stopped holding back and walked obediently beside her guard. They did not go very far, before he told her to lie down and crawl, and before she realized where she was going, she was in a deep trench that ran along the base of the rock and was completely hidden from sight.

Garibaldi followed them, picking her way daintily, and stopping every now and then to let out a mournful "Naa!" The Austrian did not seem to hear her. If he did, he paid no attention, but led Lucia hurriedly along the dark passage.

They had not gone far before a sentry stopped them. Lucia's guard said something to him that she could not understand. The sentry disappeared, to return in a few minutes with another man. From the respectful salutes that he received, Lucia decided he must be a very high officer. More talk followed which she could not understand, and then her guard turned to her.

"Follow me," he directed, and led her out of the passage across a stretch of open ground, and over to a shed. Another soldier opened the door, and before Lucia quite got her breath, she heard the key turn in a lock and the thud, thud of the men's boots as they marched away.
