He and Phyllis talked or danced together only as much as they did with everyone else; and only in the secrecy of their rooms did they embrace, kiss, make love. It was the old pattern of the hidden affair, and one morning around four A.M., returning to his room from hers, a flash of fear shook him; it seemed to him suddenly that his immediate undiscussed complicity in this behavior must tag him to Phyllis as suspiciously like one of the First Hundred. Who else would fall into such a bizarre pattern so readily, as if it were the natural thing to do?

But on consideration it did not seem that Phyllis was attentive to nuances of that kind. Sax had almost given up trying to understand her thinking and her motivations, as the data were contradictory and, despite the fact that they were spending nights together on a fairly regular basis, rather sparse. She seemed interested mostly in the intertransnational maneuvering that was going on in Sheffield, and back on Earth — shifts in executive personnel and subsidiaries and stock prices that were clearly ephemeral and meaningless, but to her utterly absorbing. As Stephen he remained brightly interested in all this, and asked her questions about it to show his interest when she brought it up, but when he asked about what the daily changes meant in any larger strategic sense, she was either unable or unwilling to give him good answers. Apparently it was interesting to her more for the personal fortunes of those she knew than for the system that their careers revealed. An ex-Consolidated executive now with Subarashii had been made head of elevator operations, a Praxis executive had disappeared in the outback, Armscor was going to explode scores of hydrogen bombs in the megaregolith under the north polar cap, to stimulate growth and warming of the northern sea; and this last fact was no more interesting to her than the two previous ones.

And perhaps it made sense to pay attention to the individual careers of the people running the biggest transnational, and the micropolitics of the jockeying for power among them. These were the current rulers of the world, after all. So Sax lay next to Phyllis, listening to her and making Stephen’s comments, trying to sort out all the names, wondering if the founder of Praxis really was a senile surfer, wondering if Shellalco would be taken over by Amexx, wondering why the transnat executive teams were so fiercely competitive, given that they already ruled the world, and had everything they could conceivably want in their personal lives. Perhaps socio-biology indeed had the answer, and it was all primate dominance dynamics, a matter of increasing one’s reproductive success in the corporate realm — which might not be a mere analogy, if one considered one’s company as one’s kin. And then again, in a world where one might live indefinitely, it could be simple self-protection. “Survival of the fittest,” which Sax had always considered a useless tautology. But if social Darwinists were taking over, then maybe the concept gained importance, as a religious dogma of the ruling order…

And then Phyllis would roll over onto him and kiss him, and he would enter the realm of sex, where different rules seemed to obtain. For instance, though he liked Phyllis less and less as he got to know her better, his attraction to her did not correlate to this, but fluctuated according to mysterious principles of its own, no doubt pheromone-driven and hormonally based; so that sometimes he had to steel himself to accept her touches, while other times he felt alive with a lust that seemed all the stronger because it was so unmixed with affection. Or more senseless still, a lust actually heightened by dislike. This last reaction was rare, however, and as the stay at Arena went on, and the novelty of their affair wore off, Sax more and more frequently found himself distanced from their lovemaking, and inclined to fantasize during it, and fall very deeply into Stephen Lindholm, who appeared to be thinking about caressing women Sax did not know or had scarcely heard of, like Ingrid Bergman or Marilyn Monroe.

One dawn, after a disturbing night of that sort, Sax got up to go out on the ice, and Phyllis stirred and woke, and decided to come along.

They suited up and went out into a pure purple dawn, and hiked in silence down the near moraine to the side of the glacier, ascending it by a trail of steps cut into the ice. Sax took the southernmost flagged trail across the glacier, intending to climb the west lateral moraine as far upstream as he could go in a morning.

They made their way between knee-high crenellations of ice, all holed like Swiss cheese, and stained pink with snow algae. Phyllis was charmed as always by the fantastic jumble, and commented on the more unusual seracs, comparing those they passed this morning to a giraffe, the Eiffel Tower, the surface of Europa, etc. Sax stopped often to inspect chunks of jade ice that were shot through with an ice bacteria. In one or two places the jade ice sat exposed in suncups turned pink with snow algae; the effect was strange, like a vast field of pistachio ice cream.

So their progress was slow, and they were still on the glacier when a sequence of small tight whirlwinds popped into existence one after the next, like something out of a magic trick: brown dust devils, glittering with ice particulates, in a rough line that bore down the glacier toward them. Then the whirlwinds collapsed in some fluctuation, and with a clattery bang a gust struck them hard, whistling downslope with a surge so powerful they had to crouch into it to keep their balance. “What a gale!” Phyllis exclaimed in his ear.

“Katabatic wind,” Sax said, watching a knot of seracs disappear in the dust. “Falling off Tharsis.” Visibility was dropping. “We should try to get back to the station.”

So they set off back along the flagged trail, moving from one emerald dot to the next. But visibility continued to decrease, until they couldn’t see from one marker to the next. Phyllis said, “Here, . let’s get into the shelter of those icebergs.”

She struck off toward the dim shape of an ice prominence, and Sax hurried after her, saying, “Be careful, a lot of seracs have crevasses at their base,” and reaching forward to take her hand, when she dropped as if falling through a trap door. He caught an upflung wrist and was jerked down hard, hitting his knees painfully on the ice. Phyllis was still falling, sliding down a chute at the end of a shallow crevasse; he should have let go of her but instinctively held on, and was dragged over the edge head first. Both of them slid down into the packed snow at the bottom of the crevasse, and the snow gave under them so that they dropped again, crashing onto frosty sand after a brief but terrifying free-fall.

Sax, having landed mostly on Phyllis, sat up unhurt. Alarming sucking sounds came over the intercom from Phyllis, but it soon became clear that she had only had the wind knocked out of her. When she controlled her gasping she tested her limbs gingerly, and declared she was okay. Sax admired her toughness.

There was a rip in the fabric over his right knee; but otherwise he was fine. He took some suit tape from his thigh pocket and taped the rip; theT^knee still bent without pain, so he forgot about it and stood.

The hole that they had punched through the snow above them was about two meters over his outstretched hand. They were in an elongated bubble, the lower half of a crevasse that had a kind of hourglass shape. The downstream wall of their little bubble was ice, the upstream wall ice-coated rock. The rough circle of visible sky overhead was an opaque peach color, and the bluish ice wall of the crevasse gleamed with reflections of the dusty sunlight, so that the net effect was somewhat opalescent, and quite picturesque. But they were stuck.

“Our beeper signal will be cut off, and then they’ll come looking,” Sax said to Phyllis as she stood up beside him.
