It wasn’t. Nevertheless, they could see on it the chamber in which the Sack had rested for what must have been a brief moment of its existence. Two men had entered the chamber, one of them the unknown who had asked his questions in Prdl, the other Senator Horrigan.

To the apparent amazement of the two men, it was the Sack which spoke first. It said, ” `Good-by’ is neither a question nor the answer to one. It is relatively uninformative.”

Senator Horrigan was obviously in awe of the Sack, but he was never a man to be stopped by something he did not understand. He orated respectfully. “No, sir, it is not. The word is nothing but an expression—”

The other man said, in perfectly comprehensible Earth English, “Shut up, you fool, we have no time to waste. Let’s get it to our ship and head for safety. We’ll talk to it there.”

Siebling had time to think a few bitter thoughts about Senator Horrigan and the people the politician had punished by betrayal for their crime in not electing him. Then the scene on the visor shifted to the interior of the spaceship making its getaway. There was no indication of pursuit. Evidently, the plans of the human beings, plus the Sack’s last-minute advice, had been an effective combination.

The only human beings with the Sack at first were Senator Horrigan and the speaker of Prdl, but this situation was soon changed. Half a dozen other men came rushing up, their faces grim with suspicion. One of them announced, “You don’t talk to that thing unless we’re all of us around. We’re in this together.”

“Don’t get nervous, Merrill. What do you think I’m going to do, double-cross you?”

Merrill said, “Yes, I do. What do you say, Sack? Do I have reason to distrust him?”

The Sack replied simply, “Yes.”

The speaker of Prdl turned white. Merrill laughed coldly. “You’d better be careful what questions you ask around this thing.”
