Biff got up from his chair and gently ushered Monica, protesting, out of the study. When he turned back, he was startled to see that an expression of worry clouded his father’s face.

“Yes, Johann, I agree.” Mr. Brewster gave the name its Germanic pronunciation, “Yohann.”

Biff could only distinguish a mumble of words coming from nearly four thousand miles away.

“Well, Johann, don’t you take any chances yourself,” Mr. Brewster continued. “Wait until I get there.... Danger? There’s always danger when the stakes are as high as those we’re playing for.... What!” Thomas Brewster’s frown deepened. “Perez Soto? You say Perez Soto is there? I don’t like that one little bit. The letter, though, you have that safely hidden?”

Again the speaker at the other end took over the conversation. Biff could hear only a scramble of sounds coming from the telephone. He saw his father nod his head absently. His brows knitted into deeper thought.

“You think your room was searched?” he exclaimed. “Had you hidden the letter?”

Biff watched his father intently. Mr. Brewster listened attentively to a long reply. At last he said, “That’s bad, Johann. Very bad. We’ll have to make the best of it, though. All right, Johann.... Yes, leaving here tomorrow ... Northwest Airlines.... Take off from Seattle early the next morning, Wednesday, at five A.M. Be in Hawaii about eight o’clock your time.... You’re stopping at the Royal Poinciana, aren’t you?... Hello ... hello ... Johann?” Thomas Brewster waited a few moments. “Hello....” Then he hung up and turned to Biff. “That’s funny. He didn’t answer. Maybe we were cut off.”

“Maybe the three minutes were up,” Biff suggested with a smile.

“That’s not as funny as you think, my boy,” his father chuckled. “Dr. Weber’s a peculiar man about some things having to do with money. A call from Honolulu to Indianapolis means nothing to him. But if the operator told him his three minutes were up, he’d hang up quickly. He obeys what he thinks are the rules.”

Biff laughed. “Isn’t Dr. Weber the famous scientist? I’m sure I’ve heard you speak of him.”
