“Are you . . . have you—” Hulse congealed. In spite of everything, he was a competent officer, Blades decided. “Please explain yourself,” he said without tone.
“Sure,” Blades obliged. “The Station hasn’t got any armament, but trust the human race to juryrig that. We commandeered the scoopships belonging to this vessel and loaded them with Jovian gas at maximum pressure. If your missile detonates, they’ll dive on you.”
Something like amusement tinged Hulse’s shocked expression. “Do you seriously consider that a weapon?”
“I seriously do. Let me explain. The ships are orbiting free right now, scattered through quite a large volume of space. Nobody’s aboard them. What is aboard each one, though, is an autopilot taken from a scooter, hooked into the drive controls. Each ’pilot has its sensors locked onto your ship. You can’t maneuver fast enough to shake off radar beams and mass detectors. You’re the target object, and there’s nothing to tell those idiot computers to decelerate as they approach you.
“Of course, no approach is being made yet. A switch has been put in every scooter circuit, and left open. Only the meteorite evasion units are operative right now. That is, if anyone tried to lay alongside one of those scoopships, he’d be detected and the ship would skitter away. Remember, a scoopship hasn’t much mass, and she does have engines designed for diving in and out of Jupe’s gravitational well. She can out-accelerate either of our vessels, or any boat of yours, and out-dodge any of your missiles. You can’t catch her.”
Hulse snorted. “What’s the significance of this farce?”
“I said the autopilots were switched off at the moment, as far as heading for the target is concerned. But each of those switches is coupled to two other units. One is simply the sensor box. If you withdraw beyond a certain distance, the switches will close. That is, the ’pilots will be turned on if you try to go beyond range of the beams now locked onto you. The other unit we’ve installed in every boat is an ordinary two-for-a-dollar radiation meter. If a nuclear weapon goes off, anywhere within a couple of thousand kilometers, the switches will also close. In either of those cases, the scoopships will dive on you.
“You might knock out a few with missiles, before they strike. Undoubtedly you can punch holes in them with laser guns. But that won’t do any good, except when you’re lucky enough to hit a vital part. Nobody’s aboard to be killed. Not even much gas will be lost, in so short a time.
“So to summarize, chum, if that rogue missile explodes, your ship will be struck by ten to twenty scoopships, each crammed full of concentrated Jovian air. They’ll pierce that thin hull of yours, but since they’re already pumped full beyond the margin of safety, the impact will split them open and the gas will whoosh out. Do you know what Jovian air does to substances like magnesium?
“You can probably save your crew, take to the boats and reach a Commission base. But your nice battleship will be ganz kaput. Is your game worth that candle?”
“You’re totally insane! Releasing such a thing—”
“Oh, not permanently. There’s one more switch on each boat, connected to the meteorite evasion unit and controlled by a small battery. When those batteries run down, in about twenty hours, the ’pilots will be turned off completely. Then we can spot the scoopships by radar and pick ’em up. And you’ll be free to leave.”
“Do you think for one instant that your fantastic claim of acting legally will stand up in court?”
“No, probably not. But it won’t have to. Obviously you can’t make anybody swallow your yarn if a second missile gets loose. And as for the first one, since it’s failed in its purpose, your bosses aren’t going to want the matter publicized. It’d embarrass them to no end, and serve no purpose except revenge on Jimmy and me—which there’s no point in taking, since the Sword would still be privately owned. You check with Earth, admiral, before shooting off your mouth. They’ll tell you that both parties to this quarrel had better forget about legal action. Both would lose.
“So I’m afraid your only choice is to find that missile before it goes off.”
“And yours? What are your alternatives?” Hulse had gone gray in the face, but he still spoke stoutly.
Blades grinned at him. “None whatsoever. We’ve burned our bridges. We can’t do anything about those scoopships now, so it’s no use trying to scare us or arrest us or whatever else may occur to you. What we’ve done is establish an automatic deterrent.”
“Against an, an attempt . . . at sabotage . . . that only exists in your imagination!”
Blades shrugged. “That argument isn’t relevant any longer. I do believe the missile was released deliberately. We wouldn’t have done what we did otherwise. But there’s no longer any point in making charges and denials. You’d just better retrieve the thing.”
Hulse squared his shoulders. “How do I know you’re telling the truth?”
“Well, you can send a man to the Station. He’ll find the scooters lying gutted. Send another man over here to the Pallas. He’ll find the scoopships gone. I also took a few photographs of the autopilots being installed and the ships being cast adrift. Go right ahead. However, may I remind you that the fewer people who have an inkling of this little intrigue, the better for all concerned.”
Hulse opened his mouth, shut it again, stared from side to side, and finally slumped the barest bit. “Very well,” he said, biting off the words syllable by syllable. “I can’t risk a ship of the line. Of course, since the rogue is still farther away than your deterrent allows the Altair to go, we shall have to wait in space a while.”
“I don’t mind.”
“I shall report the full story to my superiors at home . . . but unofficially.”
“Good. I’d like them to know that we asterites have teeth.”
“Signing off, then.”
Chung stirred. “Wait a bit,” he said. “We have one of your people aboard, Lieutenant Ziska. Can you send a gig for her?”
“She didn’t collaborate with us,” Blades added. “You can see the evidence of her loyalty, all over my mug.”
“Good girl!” Hulse exclaimed savagely. “Yes, I’ll send a boat. Signing off.”

The screen blanked. Chung and Blades let out a long, ragged breath. They sat a while trembling before Chung muttered, “That skunk as good as admitted everything.”
“Sure,” said Blades, “But we won’t have any more trouble from him.”
Chung stubbed out his cigarette. Poise was returning to both men. “There could be other attempts, though, in the next few years.” He scowled. “I think we should arm the Station. A couple of laser guns, if nothing else. We can say it’s for protection in case of war. But it’ll make our own government handle us more carefully, too.”
“Well, you can approach the Commission about it.” Blades yawned and stretched, trying to loosen his muscles. “Better get a lot of other owners and supervisors to sign your petition, though.” The next order of business came to his mind. He rose. “Why don’t you go tell Adam the good news?”
