“Ah ... and would that man’s name be Charles Keene?” Dietz went on smoothly. Now here was a twist, Biff thought. This is an angle to explore more thoroughly. “I may have heard that name,” Biff said. “To be truthful, I have.” “Then you must know that this Charles Keene represents a great danger to your father and what he has worked for so long.” This situation was growing more and more weird. Dietz was talking about Biff’s favorite uncle, but not knowing it, of course. Dietz was completely convinced that Biff was Derek and thought he was telling Derek Zook about a complete stranger. Biff already was beginning to get an idea of what Dietz was leading up to. The double-cross was becoming clearer. What Dietz didn’t know was that he was double-crossing himself. “Keene was discharged by your father. For good reason. But this made Keene furious. He swore revenge on your father.” Dietz paused. Biff could just see his Uncle Charlie’s expression when he passed Dietz’s story on to him. “We knew that Keene would be at the airport to meet you—” “How could you have known?” Biff asked. The only way Dietz could have gotten this information was directly from Uncle Charlie. Derek’s arrival evidently had not been foreseen, or Derek would have expected to be met. But his, Biff’s, arrival, had been planned by his uncle. Why would Uncle Charlie have passed this word on to Dietz? That question was a real puzzler. Biff felt he might get more of the answer by letting Dietz go on with his lying explanation. “We have kept a close watch on Keene’s actions.” That’s for sure, Biff thought. “We knew he planned to meet you at the airport. It was his intention to prevent a meeting between you and your father until he could extract certain valuable information from your father. Only then would he permit you to join him.” “And just where do you come in on this?” Biff asked. “Ah—we are your father’s friends. We have worked closely with him. That is why he asked us to meet you.” Dietz was digging a bigger hole for himself to fall into. Since he thought Biff was Derek, Dietz had no idea, of course, of how he was giving himself away.
