allowed himself a look of exasperation. “Evidently I’ll have to repeat myself to you. Very well. You know we have had to make some adjustments on our launchers. What you did not know was the reason. Under the circumstances, I think it’s permissible to tell you that several of them have a new and secret, experimental control system. One of our missions on this cruise was to carry out field tests. Well, it turned out that the system is still full of, ah, bugs. Gunnery Command has had endless trouble with it, has had to keep tinkering the whole way from Earth.
“Half an hour ago, while Commander Warburton was completing a reassembly—lower ranks aren’t allowed in the test turrets—something happened. I can’t tell you my guess as to what, but if you want to imagine that a relay got stuck, that will do for practical purposes. A missile was released under power. Not a dummy—the real thing. And release automatically arms the war head.”

The news was like a hammerblow. Blades spoke an obscenity. Sweat sprang forth under his arms and trickled down his ribs.
“No such thing was expected,” Hulse went on. “It’s an utter disaster, and the designers of the system aren’t likely to get any more contracts. But as matters were, no radar fix was gotten on it, and it was soon too far away for gyrogravitic pulse detection. The thrust vector is unknown. It could be almost anywhere now.
“Well, naval missiles are programmed to reverse acceleration if they haven’t made a target within a given time. This one should be back in less than six hours. If it first detects our ship, everything is all right. It has optical recognition circuits that identify any North American warcraft by type, disarm the war head, and steer it home. But, if it first comes within fifty kilometers of some other mass—like this asteroid or one of the companion rocks—it will detonate. We’ll make every effort to intercept, but space is big. You’ll have to take your people to a safe distance. They can come back even after a blast, of course. There’s no concussion in vacuum, and the fireball won’t reach here. It’s principally an anti-personnel weapon. But you must not be within the lethal radius of radiation.”
“The hell we can come back!” Avis cried.
“I beg your pardon?” Hulse said.
“You imbecile! Don’t you know Central Control here is cryotronic?”
Hulse did not flicker an eyelid. “So it is,” he said expressionlessly. “I had forgotten.”

Blades mastered his own shock enough to grate: “Well, we sure haven’t. If that thing goes off, the gamma burst will kick up so many minority carriers in the transistors that the p-type crystals will act n-type, and the n-type act p-type, for a whole couple of microseconds. Every one of ’em will flip simultaneously! The computers’ memory and program data systems will be scrambled beyond hope of reorganization.”
“Magnetic pulse, too,” Chung said. “The fireball plasma will be full of inhomogeneities moving at several per cent of light speed. Their electromagnetic output, hitting our magnetic core units, will turn them from super to ordinary conduction. Same effect, total computer amnesia. We haven’t got enough shielding against it. Your TIMM systems can take that kind of a beating. Ours can’t!”
“Very regrettable,” Hulse said. “You’d have to reprogram everything—”
“Reprogram what?” Avis retorted. Tears started forth in her eyes. “We’ve told you what sort of stuff our chemical plant is handling. We can’t shut it down on that short notice. It’ll run wild. There’ll be sodium explosions, hydrogen and organic combustion, n-n-nothing left here but wreckage!”
Hulse didn’t unbend a centimeter. “I offer my most sincere apologies. If actual harm does occur, I’m sure the government will indemnify you. And, of course, my command will furnish what supplies may be needed for the Pallas Castle to transport you to the nearest Commission base. At the moment, though, you can do nothing but evacuate and hope we will be able to intercept the missile.”
Blades knotted his fists. A sudden comprehension rushed up in him and he bellowed, “There isn’t going to be an interception! This wasn’t an accident!”
Hulse backed a step and drew himself even straighter. “Don’t get overwrought,” he advised.
“You louse-bitten, egg-sucking, bloated faggot-porter! How stupid do you think we are? As stupid as your Essjay bosses? By heaven, we’re staying! Then see if you have the nerve to murder a hundred people!”
“Mike . . . Mike—” Avis caught his arm.
Hulse turned to Chung. “I’ll overlook that unseemly outburst,” he said. “But in light of my responsibilities and under the provisions of the Constitution, I am hereby putting this asteroid under martial law. You will have all personnel aboard the Pallas Castle and at a minimum distance of a thousand kilometers within four hours of this moment, or be subject to arrest and trial. Now I have to get back and commence operations. The Altair will maintain radio contact with you. Good day.” He bowed curtly, spun on his heel, and clacked from the room.
Blades started to charge after him. Chung caught his free arm. Together he and Avis dragged him to a stop. He stood cursing the air ultraviolet until Ellen entered.
“I couldn’t keep up with you,” she panted. “What’s happened, Mike?”
The strength drained from Blades. He slumped into a chair and covered his face.

Chung explained in a few harsh words. “Oh-h-h,” Ellen gasped. She went to Blades and laid her hands on his shoulders. “My poor Mike!”
After a moment she looked at the others. “I should report back, of course,” she said, “but I won’t be able to before the ship accelerates. So I’ll have to stay with you till afterward. Miss Page, we left about half a bottle of wine on the verandah. I think it would be a good idea if you went and got it.”
Avis bridled. “And why not you?”
“This is no time for personalities,” Chung said. “Go on, Avis. You can be thinking what records and other paper we should take, while you’re on your way. I’ve got to organize the evacuation. As for Miss Ziska, well, Mike needs somebody to pull him out of his dive.”
“Her?” Avis wailed, and fled.
Chung sat down and flipped his intercom to Phone Central. “Get me Captain Janichevski aboard the Pallas,” he ordered. “Hello, Adam? About that general alarm—”
Blades raised a haggard countenance toward Ellen’s. “You better clear out, along with the women and any men who don’t want to stay,” he said. “But I think most of them will take the chance. They’re on a profit-sharing scheme, they stand to lose too much if the place is ruined.”
“What do you mean?”
“It’s a gamble, but I don’t believe Hulse’s sealed orders extend to murder. If enough of us stay put, he’ll have to catch that thing. He jolly well knows its exact trajectory.”
“You forget we’re under martial law,” Chung said, aside to him. “If we don’t go freely, he’ll land some PP’s and march us off at gunpoint. There isn’t any choice. We’ve had
