"Favonia!" he cried. "It is I. Where are you?"

"Here," cried the girl.

Rushing blindly in the direction of her voice, von Harben encountered one of the abductors. The fellow grappled with him, while, terrified by fear that the legionaries were upon them, the others bolted from the building. As they went they left the door open and the light of a full moon dissipated the darkness of the interior, revealing von Harben struggling with a burly fellow who had seized the other's throat and was now trying to draw his dagger from its sheath.

Instantly Mallius Lepus and Gabula were upon him, and a quick thrust of the former's sword put a definite period to the earthly rascality of the criminal. Free from his antagonist, von Harben leaped to his feet and ran to Favonia, where she lay upon a pile of dirty rags against the wall. Quickly he cut her bonds and soon they had her story.

"If you are no worse for the fright," said Mallius Lepus, "we may thank these scoundrels for simplifying our task, for here we are ready to try for our escape a full three hours earlier than we had hoped."

"Let us lose no time, then," said von Harben, "I shall not breathe freely until I am across the wall."

"I believe we have little to fear now," said Mallius Lepus. "The wall is poorly guarded. There are many places where we can scale it, and I know a dozen places where we can find boats that are used by the fishermen of the city. What lies beyond is upon the knees of the gods."

Gabula, who had been standing in the doorway, closed the door quickly and crossed to von Harben. "Lights are coming down the avenue, Bwana," he said. "I think many men are coming. Perhaps they are soldiers."

The four listened intently until they made out distinctly the measured tread of marching men.

"Some more searchers," said Mallius Lepus. "When they have passed on their way, it will be safe to depart."
