He stood, and shoved upward against the heavy roof. His feet sank in the pulpy floor, but he was able to jerk loose one of the bubble's interior ribs, now bent in an overstrained curve. He almost passed out from the effort, in the thick air. He found the top edge of the shelter's opening, and slid his finger down the burr-catch just a few centimeters. Just enough for the pole to pass through. He'd feared the black mud would pour in, drowning him at once, but it only crept in extrusive blobs, to fall with oozing plops. The comparison was obvious and repulsive. God, and I thought I'd been in deep shit before.

He shoved the rib upward. It resisted, slipping in his sweating palms. Not ten centimeters. Not twenty. A meter, a meter and a third, and he was running short on probe. He paused, took a new grip, shoved again. Was the resistance lessening? Had he broken through to the surface? He heaved it back and forth, but the sucking slime sealed it still.

Maybe, maybe a little less than his own height between the top of the shelter and breath. Breath, death. How long to claw through it? How fast did a hole in this stuff close? His vision was darkening, and it wasn't because the light was going dim. He turned the heat tube off and stuck it in the front pocket of his jacket. The uncanny dark shook him with horror. Or perhaps it was the CO2 . Now or never.

On an impulse, he bent and loosened his boot-catches and belt buckle, then zipped open the burr by feel. He began to dig like a dog, heaving big globs of mud down into the little space left in the bubble.

He squeezed through the opening, braced himself, took his last breath, and pressed upward.

His chest was pulsing, his vision a red blur, when his head broke the surface. Air! He spat black muck and bracken bits, and blinked, trying with little success to clear his eyes and nose. He fought one hand up, then the other, and tried to pull himself up horizontal, flat like a frog. The cold confounded him. He could feel the muck closing around his legs, numbing like a witch's embrace. His toes pressed at full extension on the shelter's roof. It sank and he rose a centimeter. The last of the leverage he could get by pushing. Now he must pull. His hands closed over bracken. It gave. More. More. He was making a little progress, the cold air raking his grateful throat. The witch's grip tightened. He wriggled his legs, futilely, one last time. All right, now. Heave!

His legs slid out of his boots and pants, his hips sucked free, and he rolled away. He lay spread-eagled for maximum support on the treacherous surface, face up to the grey swirling sky. His uniform jacket and long underwear were soaked with slime, and he'd lost one thermal sock, as well as both boots and his trousers.

It was sleeting.

They found him hours later, curled around the dimming heat-tube, crammed into an eviscerated equipment bay in the automated weather station. His eye-sockets were hollow in his black-streaked face, his toes and ears white. His numb purple fingers jerked two wires across each other in a steady, hypnotic tattoo, the Service emergency code. To be read out in bursts of static in the barometric pressure meter in base's weather room. If and when anybody bothered to look at the suddenly-defective reading from this station, or noticed the pattern in the white noise.

His fingers kept twitching in this rhythm for minutes after they pulled him free of his little box. Ice cracked off the back of his uniform jacket as they tried to straighten his body. For a long time they could get no words from him at all, only a shivering hiss. Only his eyes burned.

Floating in the heat tank in the base infirmary, Miles considered crucifixion for the two saboteurs from the motor pool from several angles. Such as upside-down. Dangling over the sea at low altitude from an anti-grav sled. Better still, staked out face-up in a bog in a blizzard. . . . But by the time his body had warmed up, and the corpsman had pulled him out of the tank to dry, be reexamined, and eat a supervised meal, his head had cooled.

It hadn't been an assassination attempt. And therefore, not a matter he was compelled to turn over to Simon Illyan, dread Chief of Imperial Security and Miles's father's left-hand man. The vision of the sinister officers from ImpSec coming to take those two jokers away, far away, was lovely, but impractical, like shooting mice with a maser cannon. Anyway, where could ImpSec possibly send them that was worse than here?

They'd meant his scat-cat to bog, to be sure, while he serviced the weather station, and for Miles to have the embarrassment of calling the base for heavy equipment to pull it out. Embarrassing, not lethal. They could not have—no one could have—forseen Miles's inspired safety-conscious precaution with the chain, which was in the final analysis what had almost killed him. At most it was a matter for Service Security, bad enough, or for normal discipline.

He dangled his toes over the side of his bed, one of a row in the empty infirmary, and pushed the last of his food around on his tray. The corpsman wandered in, and glanced at the remains.

"You feeling all right now, sir?"

"Fine," said Miles morosely.

"You, uh, didn't finish your tray."

"I often don't. They always give me too much."

"Yeah, I guess you are pretty, um . . ." The corpsman made a note on his report panel, leaned over to examine Miles's ears, and bent to inspect his toes, rolling them between practiced fingers. "It doesn't look like you're going to lose any pieces, here. Lucky."

"Do you treat a lot of frostbite?" Or am I the only idiot? Present evidence would suggest it.

"Oh, once the grubs arrive, this place'll be crammed. Frostbite, pneumonia, broken bones, contusions, concussions . . . gets real lively, come winter. Wall-to-wall moro—unlucky trainees. And a few unlucky instructors, that they take down with 'em." The corpsman stood, and tapped a few more entries on his panel. "I'm afraid I have to mark you as recovered now, sir."

"Afraid?" Miles raised his brows inquiringly.

The corpsman straightened, in the unconscious posture of a man transmitting official bad news. That old they-told-me-to-say-this-it's-not-my-fault look. "You are ordered to report to the base commander's office as soon as I release you, sir."

Miles considered an immediate relapse. No. Better to get the messy parts over with. "Tell me, corpsman, has anyone else ever sunk a scat-cat?"

"Oh, sure. The grubs lose about five or six a season. Plus minor bog-downs. The engineers get real pissed about it. The commandant promised them next time he'd . . . ahem!" The corpsman lost his voice.

Wonderful, thought Miles. Just great. He could see it coming. It wasn't like he couldn't see it coming.

Miles dashed back to his quarters for a quick change of clothing, guessing a hospital robe might be inappropriate for the coming interview. He immediately found he had a minor quandry. His black fatigues seemed too relaxed, his dress greens too formal for office Wear anywhere outside Imperial HQ at Vorbarr Sultana. His undress greens' trousers and half-boots were still at the bottom of the bog. He had only brought one of each uniform style with him; his spares, supposedly in transit, had not yet arrived.

He was hardly in a position to borrow from a neighbor. His uniforms were privately made to his own fit, at approximately four times the cost of Imperial issue. Part of that cost was for the effort of making them indistinguishable on the surface from the machine cut, while at the same time partially masking the oddities of his body through subtleties of hand-tailoring. He cursed under his breath, and shucked on his dress greens, complete with mirror-polished boots to the knees. At least the boots obviated the leg braces.
