They lay side by side, each in his or her own thoughts, looking outside and feeling the rover bounce on its shock absorbers. The wind was still rising, the dust now pouring down Echus Chasma and then Kasei Vallis, in a ghostly mimicry of the great outflow that had first carved the channel. Michel pushed up to check the screens. “Up to two hundred kilometers per hour.” Maya grunted. Winds had been far faster in the old days, but with the atmosphere so much thicker, these slower speeds were deceptive; present-day gales were much more forceful than the old insubstantial screamers.

Clearly they would go in tonight, it was only a matter of getting Coyote’s bursted signal. So they lay back down together and waited, tense and relaxed at the same time, giving each other thorough massages to pass the time and relieve the tension, Michel marveling throughout at the catlike grace of Maya’s long muscular body, ancient by the dates, but in most respects the same as ever. As beautiful as ever.

Then finally sunset stained the hazy air, and the monumental clouds to the east, clouds which now covered the cliff face. They got up and sponged down, and ate a meal, and dressed and sat in the drivers’ seats, getting nervous again as the quartz sun disappeared and the stormy twilight fell away.

In file dark the wind was sheer noise, and an irregular trembling of the rover on its stiff shock absorbers. Gusts buffeted the car so hard.that it was sometimes held down against the full crush of the shocks for seconds at a time, the car struggling to rise on the springs and failing, like an animal fighting to free itself from the bottom of a stream. Then the gust would let off and the car would jerk up wildly. “Are we going to be able to walk in this?” Maya asked.

“Hmm.” Michel had been out in some hard blows before, but in the dark one couldn’t be sure if this was worse than those or not. It certainly seemed like it, and the rover anemometer was now registering gusts of 230 kilometers per hour, but in the lee of their little mesa it was unclear whether these represented true maxi-mums or not.

He checked the fines gauge, and was not surprised to find it was now a full-blown dust storm as well. “Let’s drive down closer,” Maya said. “It will get us there quicker, and make it easier to relocate the car as well.”

“Good idea.”

They sat in the drivers’ seats and took off. Out of the shelter of the mesa, the wind was ferocious. At one point the bouncing grew so severe it felt as if they might be flipped over, and if they had been side-on to the wind, they might have been; as it was, with the wind behind them, they rolled on at fifteen kilometers per hour when they should have been going ten, and the motor hummed unhappily as it braked the car from going even faster. “This is too much wind, isn’t it?” Maya asked.

“ I don’t think Coyote has much control over it.”

“Guerrilla climatology,” Maya said with a snort. “That man is a spy, I’m sure of it.”

“I don’t think so.”

The cameras showed nothing but a starless black rush. The car’s AI was guiding them by dead reckoning, and on the screen’s map they were shown within two kilometers from the outer bank’s southernmost tent. “We’d better walk from here,” Michel said.

“How will we find the car again?”

“We’ll have to get out the Ariadne thread.”

They suited up and got in the. lock. When the outer door slid open the air sucked out instantly, pulling them hard. The wind keened across the doorway.

They stepped out of the lock and were slammed by great blows to the back. One knocked Michel to his hands and knees, and he could just see through the dust to Maya, in the same position beside him. He reached back into the lock and took the thread reel in one hand, Maya’s hand in the other. He clipped the reel to his forearm.

By careful experiment they found they could stand if they stayed crouched forward, helmets at waist level and hands up and ready to catch themselves if they were knocked down. They stumbled ahead slowly, crashing down when strong gusts made it impossible to stand. The ground under them was just barely visible, and a knee striking a rock was all too possible. Coyote’s wind had indeed come down too strong. But there was nothing to be done about it. And clearly the inhabitants of the Kasei tents were not going to be out wandering around.

A gust knocked them down again, and Michel let the wind pour over him. It was hard to keep from being rolled. His wristpad was connected to Maya’s by a phone cord, and he said, “Maya, are you all right?”

“Yes. And you?”

“I’m okay.”

Though there seemed to be a small tear in his glove, over the ball of his thumb. He bunched his fist, felt the cold seeping up his wrist. Well, it wouldn’t be instant frostbite the way it used to be, nor pressure bruising. He took a suit patch from his wristpad compartment, stuck it on. “I think we’d better stay down like this.”

“We can’t crawl two kilometers!”

“We can if we have to.”

“But I don’t think we do. Just stay low, and be ready to go down.”

“Okay.”

They stood again, bent double, and shuffled cautiously forward. Black dust flew past them with amazing rapidity. Michel’s navigation display lit his faceplate, down in front of his mouth: the first bubble tent was still a kilometer away, and to his astonishment the green numbers of the clock showed 11:15:16 — they had been out an hour. The howl of the wind made it hard to hear Maya, even with his intercom right against his ear. Over on the inner bank Coyote and the others, and the Red groups as well, were presumably making their raid on the living quarters — but there was no way of telling. They had to take it on faith that the shocking wind had not halted that part of the action, or slowed it down too much.

It was hard work to shuffle forward doubled over, connected by the telephone cord. On and on it went, until Michel’s thighs burned and his lower back hurt. Finally his navigation display indicated they were very close to the southernmost tent. They could see nothing of it. The wind became stronger than ever, and they crawled the final few hundred meters, over painfully hard bedrock. The clock numerals froze at 12:00:00. Sometime soon thereafter they banged into the concrete coping of the tent’s foundation. “Swiss timing,” Michel whispered. Spencer was expecting them in the timeslip, and they had thought they would have to wait at the wall until it came. He reached up and put a hand gently on the tent’s outermost layer. It was very taut, pulsing in time with the onslaught of air. “Ready?”

“Yes,” Maya said, her voice tight.

Michel took a small air gun from his thigh pocket. He could feel Maya doing the same. The guns were used with a variety of attachments, for everything from driving nails to giving inoculations; now they hoped to use them to break the tough and elastic fabrics of the tent.

They disconnected the phone cord between them, and put their two guns against the taut vibrating invisible wall. With a tap of the elbows they shot together.

Nothing happened. Maya plugged the phone cord back into her wrist. “Maybe we’ll have to slash it.”

“Maybe. Let’s put the two guns together, and try again. This material is strong, but still, with the wind …”

They disconnected, got set, tried it again — their arms were jerked over the coping, and they slammed into the concrete wall. A loud boom was followed by a lesser one, then a cascading roar, and a series of explosions. All four layers of the tent were peeling away, between two of the buttresses and maybe all across the south side, which would surely explode the whole thing. Dust was flying among the dimly lit buildings ahead of them. Windows were going dark as buildings lost lights; some appeared to be losing their windows to the sudden depressurization, although this was nowhere near as severe as it once would have been.
