"She is my sister," said Barney, looking closely at the man.
"Your sister?" questioned Nu. "I did not know you had a sister, Custer."
"You did not know my sister, Nat-ul?" cried Barney.
"Nat-ul!" exclaimed the man. "Nat-ul your sister?"
"Yes. I supposed that you knew it."
"But you are not Aht, son of Tha," said Nu, "and Nat-ul had no other brother."
"I am brother of the girl you saved from the lion in the garden yonder," said Barney. "Is it she you know as Nat-ul?"
"She was Nat-ul."
"Where is she?" cried Barney.
"I do not know," replied Nu. "I thought that she was a prisoner among you and I have been waiting here quietly for her to be brought back."
