The professor leaned forward. "Commander, I'm telling you-if you don't secure that base, and keep the mutiny from getting hold of those weapons, you'll wish you had to the end of your life, which will probably not be a long one. Now several things can happen. We can try to go back and not make it and crash in the sea. We can try to go back and-if enough of the personnel are involved-they might shoot us out of the sky, if they happen to notice us. We can get there and fail to secure the base, although I believe if you send along enough troops that won't happen. We can get there and secure the base, and the mutineers topside can land a force and drive us off . . . but if we have enough time, we'll have destroyed at least the worst of the weapons. Or we can sit here and do nothing, and be dead with no chance of helping out." He sat back. "I personally think that is the worst option."

"I-I should contact Commander Polacek."

"No, Commander, you should not. You've already said you aren't sure of his loyalty. You know communications are compromised. You know what my authority is."

"He's right," Margiu said, surprising herself by speaking up. "If we're going back out there, we have to do it before they send shuttles down."

Ardsan looked from one to the other, frowning. Finally he sighed. "All right. All right . . . let me think. We need transport that can land at Stack Two and carry troops-" He touched his desk comunit. "Chief-look up what we have on the personnel at Stack Two. And give me an estimate of our

security forces here."

The professor interrupted. "Are there any heavy cargo craft based here?"

"We have the heavy-duty aircars we use along the coast, but we don't like to take them out over the open ocean. They sink like rocks if the power plant fails. That's why we use the amphibs."

"How long would it be before the mutineers could send shuttles down?"

"Depends on whether the station had any short-field shuttles ready to go. The usual shuttles require longer landing fields; there are only four long fields on the whole planet, and two of them are only used for emergencies. The LACs from Bonar Tighe can do it, of course, but they'll require refueling and service-at least a couple of hours of turnaround. Those other ships . . . I don't know which had LACs, and if those LACs were ready for drop. Then unless a ship did a low pass, the LACs would need several hours-I don't really know how many-to fly in. If they launched additional LACs immediately after taking the station, the mutineers could be on that island now.

Or, if they're delayed, it could be tomorrow or the next day."

"And the flight times of your available craft?"

"Depends on the windspeed and direction-and we have no weathersats now. Five hours, six-I can't say exactly."

One of the enlisted men poked his head in the door. "Sir, Stack Two has thirteen civilian scientist personnel, five officers, and twenty-nine enlisted. Commander's a Lieutenant Commander Vinet. We've got fifteen NEM assault troops, and thirty ordinaries, plus the base police."

"Thank you. Carry on." Ardsan grimaced. "Enough to tempt us into trouble, and not enough to get us out-and if I strip Dark Harbor, there's no one to protect the people here-" Then he shook his head as if to clear it. "All right. It's something definite, at least. Professor, I assume you're going-"

"Absolutely," he said. "You need me to disable those weapons, and the scientists and engineers know me."

"Ensign, I'm assigning you to the professor, since he seems to have confided in you before. You are weapons-qualified, right?"

"Yes, sir." She had gone hunting as a girl; she knew she was good with firearms, and her qualifying scores had always maxed out.

"Good. I'll have the armsmaster issue you weapons; I want you to stick to the professor like glue, and watch his back. Just in case any of the people we send along aren't as loyal as we think they are."

"Yes, sir."

"Professor, it'll take some time to fuel the aircraft, brief the aircrew, and assemble the troops.

You'd better eat and rest while you can. Ensign, you too-but you stick with him, you hear?"

"Yes, sir." She realized suddenly that she was very hungry, and also tired, and that she would have to go back out over that cold, wet, vast ocean . . . in the dark.

In the mess, where she and the professor ate, she overheard another conversation.

"It's that damned rejuvenation stuff," the crew chief said. "It doesn't take a grand admiral strategist to see what enormously prolonged youth will do to the career curve of anyone below rejuv age. Promotions started slowing down ten or fifteen years ago, right about when they were doing those senior NCO rejuvs . . . you don't spend all that money on rejuvenating someone and then retire 'em, now do you? And the people who might expect to step into that job see they won't have a chance. Expansion helped some, but how big a space force do we need?"

"But . . . mutiny, Chief. Can you see mutiny?"

"Not right away, no. And not for me, personally, ever. But there's been a rumor that something was wrong with the NCO rejuvenations, and some people-not me-said they were bollixed on purpose. It was one thing to have too many young-old admirals, but they didn't want the enlisted getting ideas."

"Now that makes no sense," the professor broke in. "Senior enlisted are the backbone of every successful military organization-always have been. Admirals are fine, and if you have a strategic genius you certainly want to keep him, but day to day, you need senior NCOs."

"Militaries have made that mistake before. Rank-heavy, officer dominated . . ."

"Well, I used to work in Personnel Procurement," another chief said. "Back when I was a young sergeant. I saw projections of need by rank and grade, and back then, at least, the planners knew they needed more master chiefs than admirals. So I don't think they'd deliberately sabotage a rejuvenation program for chiefs."

"Somebody sure did. Remember Chief Wang last year? We had to watch him every second, or he'd put a six-star fastener in a four-point hole, and tell everybody to do the same. I never saw anything like it, and it wasn't pretty."

"I thought they said it was some brain virus or something, from his fishing trips to the mountains."

"That's what they said then, but when we got that directive on removing rejuved chiefs from active duty until they'd been checked, that's who I thought of. 'Course, he was medically retired by then, but I asked Pauli in sickbay, and he said he thought it probably had been a bad rejuv."

"Bad rejuvs would let the people below move up . . ." a sergeant said softly. "Not that anyone would do something like that . . . I saw Chief Wang right at the end."

"Maybe they didn't know what it would do. I remember giving my mom's pet sarri a cookie once, just sharing, y'know, and it went into convulsions and died. I had no idea they couldn't eat our kind of food. But it was just as dead as if I'd poisoned it on purpose."

"That's true. Never attribute to malice what could be stupidity. It's just as likely to be a cost- containment effort by procurement or even the manufacturer."

Margiu had not even realized that some Fleet personnel had been rejuvenated; she couldn't remember anyone mentioning it in the Academy. She wondered if any of the people in that room had been rejuved. How could she tell?

When the professor finished eating, he touched her sleeve. "Ensign-we'd better get some rest while we can. Do you remember where Commander Ardsan said we could bunk?"

Margiu showed him to the assigned room-clearly an officer's quarters, now theirs for a few hours.

They took turns in the shower, and changed into clean clothes. But before either of them dozed off, the commander told them that transport was ready.

This time the professor donned his PPU over street clothes, and then put his yellow leather jacket on top. "My friends out there will recognize this," he pointed out.

"You're a fine target that way." The major who had met them at the quay was in charge of the mission; Margiu now knew his name-Antony Garson. A Lieutenant Lightfoot commanded the troops.

"True, but if we have to make a hostile landing, at least our side will know who I am."

Margiu, who had on a clean PPU set to midnight blue-the default night-camouflage color, caught the major's eye. He shrugged, and went to check on the rest of the group. Though it was only afternoon, the heavy cloud cover and spitting rain made it seem much later.

By the time they neared the Stack Islands again, daylight had faded into murky night. They'd had clouds all the way, which was supposed to be protective, though Margiu found it dreary as the plane seemed to crawl between two layers of darkening gray. As the light failed, no lights came on in the plane-for security reasons, she was told-but she could feel, all around her, the bulky shapes of the NEMs. The professor had fallen asleep, snoring as musically as the first time, and Margiu leaned cautiously against his shoulder, letting herself doze. She couldn't lean the other way; the unfamiliar sidearm poked her. She woke when the plane slanted downward, and peered out the window into darkness.

"Umph!" That was the professor, almost choking on a final snore. "See anything?"

"No-it's all dark." How were they going to land? What if they ran into Stack Two, instead of landing on it? She could feel the plane sinking under her, and her ears popped repeatedly.

Then a sparkle of light appeared, somewhere in the gloom . . . a tiny bright line, then another line.

"Lights," she said to the professor.

As they drew closer, she could see that the lights outlined an ordinary runway, and other lights showed in buildings nearby. It looked so normal. . . .

The plane landed hard, bounced, came down firmly, and she rocked forward as the brakes caught.

Instead of rolling up to one of the lighted buildings, the plane swung aside near the end of the landing strip. The NEMs were on their feet as soon as it landed. Margiu, lacking orders, stayed where she was; she and the professor had earbugs set to the same communications channel. Another plane, then another, came to a stop near them. In the dark, with only faint light from the runway lights, Margiu could just make out dark figures leaving one of the other planes.
