"She is there now, and the man will protect her as long as is necessary. He has promised me that if he hears nothing from me for half a moon he is to understand that none of us three can come to her aid, and that then he will get word to the faithful slaves of the house of Thudos. He says that that will be difficult but not impossible."

"Doria safe!" whispered Gemnon. "Thudos and I may now die happy."

Thudos extended his hand through the darkness and laid it on the ape-man's shoulder. "There is no way in which I can express my gratitude," he said, "for there are no words in which to couch it."

For some time the three men sat in silence that was broken at last by Gemnon. "How did it happen that you knew the brother of a slave well enough to carry a message from one to the other?" he asked, a note of puzzlement in his voice.

"Do you recall Xerstle's grand hunt?" asked Tarzan with a laugh.

"Of course, but what has that to do with it?" demanded Gemnon.

"Do you remember the quarry, the man we saw on the slave block in the market place?"

"Yes."

"He is the brother of Niaka," explained Tarzan.

"But you never had an opportunity to speak to him," objected the young noble.
