“What does he want you to do?” Biff asked.
“Just sign a paper.”
“Sign a paper? Is that all?” Biff asked, disbelief in his voice.
Charlie Keene nodded his head. “It would be quite a document, Biff. He hasn’t let me read it, but from what he has said, I get the message.”
“But why the paper, Uncle Charlie?”
“That’s what I’m not altogether sure of. I think Ping Lu believes—in fact, I know he does—he’s convinced that I came into China for a reason quite different from the real one. He believes the reason I gave him for daring to enter this forbidden country is merely a cover-up story for my real mission.”
“What does he think you’re doing here?” Biff insisted.
Charles Keene grinned. “He has me marked as a big fat spy.”
An idea was buzzing around Biff’s mind. He thought he might have stumbled on why Ping Lu was spy-minded. But he’d tell Uncle Charlie about that later. He wanted to know some other things first.
“But how does this all connect up with me?” Biff asked.
