"Be careful how you answer, boy. You're not now in school, and you haven't a school-master to deal with. Is this the first time you've been here?"

"Once."

"As you were to my father when I was a child." The words were upon Paul's lips, but he forced them back. Then aloud, "I've not been a spy. I've told no one."
Zuker looked searchingly into Paul's face.
