"He's hiding something," Adams said. "And not all of him is human."

"You're going to have him killed?"

"What he knows," said the masked voice, "is better dead with the man who knows it."

"Perhaps," said Adams, "we could come to an understanding if you would tell me what this is all about."

"I can't tell you, Adams. I wish I could. I can't tell you the future."

"And until you do," snapped Adams, "I won't let you change the past."
