Urteil's hand, which had come down with such hard finality, now showed the carved metallic haft of a force-knife growing out of it.

Dr. Peverale scraped his chair back suddenly, and there was a cry or an exclamation from every man there but Bigman himself. Even Lucky seemed startled.

Bigman's tenor voice rose in delight. "Spread your fingers, you tub of mineral oil. Spread them and then grease back down into your seat."

Urteil stared at his small tormenter without understanding for a moment and then very slowly spread his fingers. His hand was not hurt, not a sliver of skin had been removed. The force-knife stood quivering in the hard plastic table top, an inch of its waveringly luminescent force-blade (it wasn't matter, merely a thin field of immaterial force) in sight. The knife had entered the table, working its way neatly and unerringly between the second and third finger of Urteil's hand.

Urteil snatched Ms hand away as though it were suddenly in flames.

Bigman crowed with delight and said, "And next time you reach a hand in Lucky's direction or in mine, you cobber, I chop it right off. What would you say if I told you that? And whatever you say, say it politely." He reached out for the force-knife, deactivating the blade as he seized the haft, and returned it to its inconspicuous holster on his belt.

Lucky said, with a light frown, "I wasn't aware that my friend was armed. I'm sure he's sorry for having disturbed the meal, but I believe Mr. Urteil may take this incident to heart."

Someone laughed and there was a tight smile on Mindes's face.

Urteil looked with hot eyes from face to face. He said, "I won't forget this treatment. It's obvious to me that the senator is receiving little co-operation, and he'll hear of that. And meanwhile, I'm staying right here." He folded his arms as though daring anyone to make Mm leave.

Little by little the conversation grew general.

Lucky said to Dr. Peverale, "You know, sir, it seems to me that your face is familiar."

"Is it?" The astronomer smiled in a strained fashion. "I don't think I ever met you before."

"Well, were you ever on Ceres?"

"Ceres?" The old astronomer looked at Lucky with some surprise. He had obviously not yet recovered from the force-knife episode. "The largest observatory in the Solar System is on that asteroid. I worked there as a young man, and I frequently visit it even now."

"Then I wonder if I didn't perhaps see you there."

Lucky couldn't help thinking, as he spoke, of those exciting days when the chase was on for Captain Anton and the pirates who were making their lair in the asteroids. And particularly the day when the pirate ships raided the very heart of Council territory, onto the surface of Ceres itself, winning out temporarily by the very daring of their undertaking.

But Dr. Peverale was shaking his head in gentle good humor. "I would have been certain, sir, had I had the pleasure of seeing you there. I am sure I did not."

"Too bad," said Lucky.

"The loss is mine, I assure you. But then it was my season for loss. As a result of an intestinal ailment, I missed all the excitement in connection with the pirate raid. I knew of it only through the conversations I overheard among my nurses."

Dr. Peverale looked about the table now, his good humor restored. The dessert was being served by the mechanical tray-carrier. He said, "Gentlemen, there has been some discussion of Project Light."

He paused to smile benignly, then went on. "It isn't exactly a happy subject under the circumstances, but I have been thinking a good deal about the accidents that have disturbed so many of us. It seems it would be a good time for me to give you all my thoughts on the matter. After all, Dr. Mindes is here. We have had a good meal. And, finally, I have something interesting to say."

Urteil broke a long silence to ask grimly, "You, Dr. Peverale?"

The astronomer said mildly, "Why not? I have had interesting things to say many times in my life. And I will say what's on my mind now." There was a sudden gravity about him. "I believe I know the whole truth, the exact truth. I know who is causing the destruction in connection with Project Light and why."
