Tom took the card he was holding out, looked at the name and the tiny gold symbol in the corner, a letter "J" in the center of a triangle. He handed the card to Greg. "I've seen you before," he told the fat man.

"What do you want with us?"

Tawney smiled again, spreading his hands. "We've heard about the tragedy, of course. A shocking thing ... Roger was one of our group so recently. We wanted you to know that if there is anything at all we can do to help, we'd be only too glad...."

"Thanks," Greg said. "But we're doing just fine."

Tawney's smile tightened a little, but he hung onto it. "I always felt close to your father," he said. "All of us at Jupiter Equilateral did.

We were all sorry to see him leave."

"I bet you were," Greg said, "he was the best mining engineer you ever had. But Dad could never stand liars, or crooked ways of doing business."

One of the men started for Greg, but the fat man stopped him with a wave of his hand. "We had our differences of opinion," he said. "We saw things one way, your father saw them another way. But he was a fine man, one of the finest...."

"Look, Mr. Tawney, you'd better say what you came to say and get out of here," Greg said dangerously, "before we give your friends here something to do."

"I merely came to offer you some help," Tawney said. He was no longer smiling. "Since your father's death, you two have acquired certain responsibilities. I thought we might relieve you of some of them."

"What sort of responsibilities?"

"You have an unmanned orbit-ship which is now a derelict in the Asteroid Belt. You have a scout-ship out there also. You can't just leave them there as a navigation hazard to every ship traveling in the sector.

There are also a few mining claims which aren't going to be of much value to you now."

"I see," Greg said. "Are you offering to buy Dad's mining rig?"

"Well, I doubt very much that we'd have any use for it, as such. But we could save you the trouble of going out there to haul it in."

"That's very thoughtful," Greg said. "How much are you offering?"

Tom looked up in alarm. "Wait a minute," he said. "That rig's not for sale...."

"How much?" Greg repeated.

"Forty thousand dollars," Merrill Tawney said. "Ship, rig and claims.

We'll even pay the transfer tax."

Tom stared at the man, wondering if he had heard right. He knew what Roger Hunter had paid for the rig; he had been with Dad when the papers were signed. Tawney's offer was three times as much as the rig was worth.

But Greg was shaking his head. "I don't think we could sell at that price."

The fat man's hands fluttered. "You understand that those ships are hardly suited to a major mining operation like ours," he said, "and the claims...." He dismissed them with a wave of his hand. "Still, we'd want you to be happy with the price. Say, forty-five thousand?"

Greg hesitated, shook his head again. "I guess we'd better think it over, Mr. Tawney."

"Fifty thousand is absolutely the top," Tawney said sharply. "I have the papers right here, drawn up for your signatures, but I'm afraid we can't hold the offer open."

"I don't know, we might want to do some mining ourselves," Greg said.

"For all we know, Dad might have struck some rich ore on one of those claims."

Tawney laughed. "I hardly think so. Those claims were all Jupiter Equilateral rejects. Our own engineers found nothing but low grade ore on any of them."

"Still, it might be fun to look."

"It could be very expensive fun. Asteroid mining is a dangerous business, even for experts. For amateurs...." Tawney spread his hands.

"Accidents occur...."

"Yes, we've heard about those accidents," Greg said coldly. "I don't think we're quite ready to sell, Mr. Tawney. We may never be ready to sell to you, so don't stop breathing until we call you. Now if there's nothing else, why don't you take your friends and go somewhere else?"

The fat man scowled; he started to say something more, then saw the look on Greg's face, and shrugged. "I'd advise you to give it some careful thought," he said as he started for the door. "It might be very foolish for you to try to use that rig."

Smiling, Greg closed the door in his face. Then he turned and winked at Tom. "Great fellow, Mr. Tawney. He almost had me sold."

"So I noticed," Tom said. "For a while I thought you were serious."

"Well, we found out how high they'd go. That's a very generous outfit Mr. Tawney works for."

"Or else a very crooked one," Tom said. "Are you wondering the same thing I'm wondering?"

"Yes," Greg said slowly. "I think I am."

"Then that makes three of us," a heavy voice rumbled from the bedroom door.

Johnny Coombs was a tall man, so thin he was almost gangling, with a long nose and s.h.a.ggy eyebrows jutting out over his eyes. With his rudely cropped hair and his huge hands, he looked like a caricature of a frontier Mars-farmer, but the blue eyes under the eyebrows were not dull.

"Johnny!" Tom cried. "We were trying to find you."

"I know," Johnny said. "So have a lot of other people, includin' your friends there."

"Well, did you hear what Tawney wanted?"

"I'm not so quick on my feet any more," Johnny Coombs said, "but I got nothin' wrong with my ears." He scratched his jaw and looked up sharply at Greg. "Not many people nowadays get a chance to bargain with Merrill Tawney."

Greg shrugged. "He named a price and I didn't like it."

"Three times what the rig is worth," Coombs said.

"That's what I didn't like," Greg said. "That outfit wouldn't give us a break like that just for old times' sake. Do you think they would?"

"Well, I don't know," Johnny said slowly. "Back before they built the city here, they used to have rats getting into the grub. Came right down off the ships. Got rid of most of them, finally, but it seems to me we've still got some around, even if they've got different shapes now."

He jerked his thumb toward the bedroom door. "In case you're wondering, that's why I was standin' back there all this time ... just to make sure you didn't sell out to Tawney no matter what price he offered."

Tom jumped up excitedly. "Then you know something about Dad's accident!"

"No, I can't say I do. I wasn't there."

"Do you really think it was an accident?"
