"Will you tell us how you got where you are?" asked Mr. Phipps.

"That's a secret," replied the girl.

"And I presume your name is a secret too?"

"Yes."

"We'll find out who you are when we get out of here. I promise you that," threatened the assistant superintendent.

"Then good-bye."

"No, no, don't go! Don't go!" begged Tad.

"Say you won't tell on her, Mr. Phipps. Don't you see—"

"All right, girl, I'll promise to keep your secret."

"You'd better," retorted the girl.
