Gorgon Medusa are closely related.'"

"What does that mean?" Malley asked.

"I don't know," Cercy puzzled. "He was always interested in folklore."

"Sounds schizophrenic," the psychiatrist said.

Cercy read it again. "'Upon further consideration, I can see that
Chaos and the Gorgon Medusa are closely related.'" He stared at it.
"Isn't it possible," he asked Malley, "that he was trying to give us a
clue? Trying to trick himself into giving and not giving at the same
time?"

"It's possible," Malley agreed. "An unsuccessful compromise--But what
could it mean?"

"Chaos." Cercy remembered Darrig's mentioning that word in his
telephone call. "That was the original state of the Universe in Greek
myth, wasn't it? The formlessness out of which everything came?"

"Something like that," Malley said. "And Medusa was one of those three
sisters with the horrible faces."

Cercy stood for a moment, staring at the paper. Chaos ... Medusa ...
and the organizing principle! Of course!

"I think--" He turned and ran from the room. Malley looked at him;
then loaded a hypodermic and followed.

In the control room, Cercy shouted Harrison into consciousness.

"Listen," he said, "I want you to build something, quick. Do you hear
me?"

"Sure." Harrison blinked and sat up. "What's the rush?"

"I know what Darrig wanted to tell us," Cercy said. "Come on, I'll
tell you what I want. And Malley, put down that hypodermic. I haven't
cracked. I want you to get me a book on Greek mythology. And hurry it
up."

Finding a Greek mythology isn't an easy task at two o'clock in the
morning. With the aid of FBI men, Malley routed a book dealer out of
bed. He got his book and hurried back.

Cercy was red-eyed and excited, and Harrison and his helpers were
working away at three crazy looking rigs. Cercy snatched the book from
Malley, looked up one item, and put it down.

"Great work," he said. "We're all set now. Finished, Harrison?"

"Just about." Harrison and ten helpers were screwing in the last
parts. "Will you tell me what this is?"

"Me too," Malley put in.

"I don't mean to be secretive," Cercy said. "I'm just in a hurry. I'll
explain as we go along." He stood up. "Okay, let's wake up the
Ambassador."

They watched the screen as a bolt of electricity leaped from the
ceiling to the Ambassador's bed. Immediately, the Ambassador vanished.

"Now he
