"Yes, but my news isn't as good as yours," frowned Walters. "They've already made use of their knowledge of the light-key. They held up a Solar Guard transport en route to t.i.tan and emptied her armory. They took a couple of three-inch atomic blasters and a dozen paralo-ray guns and rifles. Opened the energy lock with their adjustable light-key as easily as if it had been a paper bag. It looks as though they're setting themselves up for a long siege."

"Do you have any idea where they might be hiding, sir?"

"Somewhere in the asteroid belt, I believe," replied the commander.

"They headed for the belt after they held up the transport."

"Well, we'll do what we can from our end, sir," said Strong. "Since Mars is closer to the asteroid belt than any other planet, they might be using Marsopolis as a hangout. Or someone might have seen them recently."

"Use whatever plan you think best, Steve. I'm counting on you."

"Thank you, sir."

"s.p.a.ceman's luck! End transmission."

"End transmission," replied Strong and flipped off the screen.

Fifteen minutes later, the _Dog Star_ settled on a blast-scorched ramp at the Marsopolis s.p.a.ceport, and after a hasty review of their plans, the four s.p.a.cemen left the ship. Strong had a brief argument with a customs officer over a personal search for small arms. They were forced to leave their paralo-ray guns on the ship. Disgruntled, as far as the customs agents were concerned, Strong was actually pleased with the success of their disguise as merchant s.p.a.cemen.

Tom and Strong found the s.p.a.celanes Bar in the roughest and darkest section of Marsopolis. It was large and almost empty. But Tom noted that it was just like many other such places he had been in in Luna City. The walls were scarred and dirty, the floor littered, and the tables and chairs looking as if they had been used in a hundred fights. Behind a bar that ran the length of one wall, a heavy-set man with beady black eyes watched their approach.

"What's your pleasure, s.p.a.cemen?" asked the bartender in a gruff voice.

Strong hesitated a moment and decided to play all his cards at one turn.

"We'll have a thousand credits worth of information."

The barman's eyes narrowed into black slits. "What kind of information would bring that kind of a price?" he asked.

"Information about a man," said Strong.

"What man?" asked the barman. He dropped his hand out of sight behind the bar. Tom's eye caught the move and he wished the customs men hadn't taken away their paralo-ray guns.

Just at that moment he heard Roger's unmistakable laugh and turned to see the blond cadet, followed by Astro, enter, cross the room, and slap the bar for service.

"Let me take care of these two," muttered the bartender and walked down to the end of the bar. Facing Roger and Astro, he snarled, "What'll it be?"

"Coupla bottles of Martian water," drawled Roger.

"Get out of here," roared the bartender. "We don't sell kids' drinks in here."

"Two bottles of Martian water!" growled Astro and leaned over the bar threateningly. Strong and Tom watched the performance with amused eyes.

Without a word, the barman opened the bottles of Martian water and gave them to Roger and Astro. He turned back to Strong.

"These young rocketheads think they're so blasted tough," he sneered, "and then drink kids' soda pop."

Strong looked at Roger and Astro. "That fellow on the right," indicating Astro's size, "looks like he could be a little more than a child, if he got mad."

The barman snorted and leaned over the bar. "What about that thousand credits?" he asked.

"What about it?" countered Strong.

"That's a lot of money just for information," said the barman.

"It's my money," replied Strong coolly, "and my business!"

"What kind of information you interested in," asked the bartender.

"I told you, information about a man," said Strong. "Gus Wallace. Happen to know him?" Strong pulled a roll of crisp credit notes out of his jacket pocket. The barman looked at them greedily.

"Maybe. What'cha want with him?" he asked.

"He knifed a friend of ours in here two years ago."

"Yeah?" drawled the barman. "Who?"

"Pete," answered Strong, suddenly realizing he didn't know the scar-faced man's last name.

"Pete? Pete who?" asked the barman craftily.

"What are you trying to do?" snapped Tom suddenly. "Play s.p.a.ce lawyer?

You know Pete was knifed in here by Gus Wallace two years ago! Carved up good!" He made a slashing gesture from his ear to his throat, indicating the scar on Pete's face.

"So you want Wallace, eh?" mused the bartender.

"We want him a thousand credits' worth," said Strong.

"You didn't tell me for what, yet."

"None of your s.p.a.ce-blasting business," roared Strong. "You want the thousand or not?"

The bartender couldn't keep his eyes off the crisp roll of credit notes Strong rippled under his nose and hesitated. "Well, to tell you the truth, I ain't seen him for a long time."

"Then do you know anyone who has?" asked Strong.

"Hard to tell," said the bartender huskily. "But I do know the guy who would know if anyone does."

"Who?" asked Tom.

"On Venusport's s.p.a.ceman's Row. There's a joint called the Cafe Cosmos.

Go there and ask for a little guy named Shinny. Nicholas Shinny. If anyone knows about Wallace, he'll know."

Tom's heart almost stopped. Nicholas Shinny was a retired s.p.a.ceman who had taken part in his last adventure to Alpha Centauri, and was a good friend of Strong's and the _Polaris_ unit. Shinny had always operated on the edge of the s.p.a.ce code. Nothing illegal, but as Shinny himself put it, 'just bending the code a little, not breaking it.'

Tom spoke up. "That's only worth a hundred credits," he said.

"Whaddya mean!" snapped the barman.

"How would Nick Shinny know Gus Wallace?" asked Strong.

"They prospected the asteroids together years ago."
