Lucky's eyes narrowed. "Let's receive, Bigman."

The voice came through with that trace of accent, that broadening of vowels and sharpening of consonants. It was a Sirian voice.

It said, "-fy yourselves before we are forced to place a grapple on you and take you into custody. You have fourteen minutes to acknowledge reception." There was a minute's pause. "By authority of the Central Body, you are ordered to identify yourself before we are forced to place a grapple on you and take you into custody. You have thirteen minutes to acknowledge reception."

Lucky said coldly, "Reception acknowledged. This is The Shooting Starr of the Terrestrial Federation, orbiting peacefully in the spatial volume of the Terrestrial Federation. No authority other than that of the Federation exists in these spaces."

There was a second or two of silence (radio waves travel with only the speed of light) and the voice retorted, "The authority of the Terrestrial Federation is not recognized on a world colonized by the Sirian peoples."

"Which world is that?" asked Lucky.

"The uninhabited Saturnian system has been taken possession of in the name of our government under the interstellar law that awards any uninhabited world to those who colonize it."

"Not any uninhabited world. Any uninhabited stellar system."

There was no answer. The voice said stolidly, "You are now within the Saturnian system and you are requested to leave forthwith. Any delay in acceleration outward will result in our taking you into custody. Any further ships of the Terrestrial Federation entering our territory will be taken into custody without additional warning. Your acceleration out of the Saturnian system must begin within eight minutes or we will take action."

Bigman, his face twisted with unholy glee, whispered, "Let's go in and get them, Lucky. Let's show them the old Shooter can fight."

But Lucky paid no attention. He said into the transmitter, "Your remark is noted. We do not accept Sirian authority, but we choose, of our own will, to leave and will now do so." He snapped off contact.

Bigman was appalled. "Sands of Mars, Lucky! Are we going to run from a bunch of Sirians? Are we going to leave that capsule in Saturn's rings for the Sirians to pick up?"

Lucky said, "Right now, Bigman, we have to." His head was bent and his face was pale and strained, but there was something in his eyes that was not quite that of a man backing down. Anything but that.

4. Between Jupiter and Saturn

The ranking officer in the pursuing squadron (not counting Councilman Wessilewsky, of course) was Captain Myron Bernold. He was a four-striper, still under fifty, and with the physique of a man ten years younger. His hair was graying, but his eyebrows were still their original black and his beard showed blue about his shaven chin.

He stared at the much younger Lucky Starr with undisguised scorn. "And you backed away?"

The Shooting Starr, having headed inward toward the Sun again, had met the ships of the squadron approximately halfway between the orbits of Jupiter and Saturn. Lucky had boarded the flagship.

He said now quietly, "I did what was necessary to be done."

"When the enemy had invaded our home system, retreat can never be necessary. You might have been blown out of space, but you would have had time to warn us and we would have been there to take over."

"With how much power left in your micro-pile units, Captain?"

The captain flushed. "Nor would it matter if we got blasted out of space. That couldn't have been done before we had, in our rum, alerted home base."

"And started a war?"

"They've started the war. The Sirians… It is now my intention to move on to Saturn and attack."

Lucky's own rangy figure stiffened. He was taller than the captain, and his cool glance did not waver. "As full Councilman of the Council of Science, Captain, I outrank you and you know it. I will give no orders to attack. The orders I give you are to return to Earth."

"I would sooner… " The captain was visibly

struggling with his temper. His fists clenched. He said in a strangled voice, "May I ask the reason for the order, sir?" He emphasized the syllable of respect with heavy irony. "If, sir, you would be so good as to explain the excellent reason you no doubt have, sir. My own reasoning is based on a small tradition that the fleet happens to have. A tradition, sir, that the fleet does not retreat, sir."

Lucky said, "If you want my reasons, Captain, sit down and I'll give them to you. And don't tell me the fleet does not retreat. Retreat is a part of the maneuver of war, and a commanding officer who would rather have his ships destroyed than retreat has no business in command. I think it's only your anger that's speaking. Now, Captain, are we ready to start a war?"

"I tell you they have already started. They have invaded the Terrestrial Federation."

"Not exactly. They've occupied an unoccupied world. The trouble is, Captain, that the Jump through hyperspace has made travel to the stars so simple that Earthmen have colonized the planets of other stars long before ever colonizing the remoter portions of our own Solar System."

"Terrestrials have landed on Titan. In the year… "

"I know about the flight of James Francis Hogg. He landed on Oberon in the Uranian system also. But that was just exploration, not colonization. The Saturnian system was left empty, and an unoccupied world belongs to the first group that colonizes it."

"If," said the captain heavily, "that unoccupied planet or planetary system is part of an unoccupied stellar system. Saturn isn't that, you'll admit. It's part of our Solar System, which, by the howling devils of space, is occupied."

"True, but I don't think there is any official agreement to that effect. Perhaps it may be decided that Sirius is within its rights in occupying Saturn."

The captain brought his fist down upon his knee. "I don't care what the space lawyers say. Saturn is ours, and any Earthman with blood in him will agree. We'll kick the Sirians off and let our weapons decide the law."

"But that's exactly what Sirius would want us to do!"

"Then let's give her what she wants."

"And we will be accused of aggression… Captain, there are fifty worlds out there among the stars who never forget that they were our colonies once. We gave them their freedom without a war, but they forget that. They only remember we are still the most populous and most advanced of all the worlds. If Sirius shouts we have committed unprovoked aggression, she'll unite them against us. It is just for that reason that she is trying to provoke us to attack now, and it is just for that reason that I refused the invitation and came away."

The captain bit at his lower lip and would have answered, but Lucky drove on.

"On the other hand, if we do nothing, we can accuse the Sirians of aggression and we'll split public opinion in the outer worlds wide open. We can exploit that and bring them to our own side."

"The outer worlds to our side?"

"Why not? There isn't a stellar system in existence that doesn't have hundreds of unoccupied worlds of all sizes. They won't want to set up a precedent that would set every system to raiding every other system for bases. The only danger is that we will stampede them into opposition to us by making it look as if we are powerful Earth throwing our weight about against our former colonies."

The captain rose from his seat and strode the length of his quarters and then back. He said, "Repeat your orders."

Lucky said, "Do you understand my reason for retreat?"

"Yes. May I have my orders?"

"Very well. I order you to deliver this Capsule I now give you to Chief Councilman Hector Conway. You are not to discuss anything that has happened during this pursuit with anyone else, either on the sub-ether or in any other fashion. You are to take no hostile action-repeat, no hostile action-against any Sirian forces, unless directly attacked. And if you go out of your way to meet such forces, or if you deliberately provoke attack, I shall see you court-martialed and convicted. Is all clear?"
