There had been some warning, conveyed by Dr. Dvalis intermittently-functional telecom receiver. The precipitation had been relatively light in Port Magellan, but dense waves of it were falling in the west, as if focused there.

By the time Dr. Dvali announced this news, the threat was ominously visible. Lise, looking through the back window of the vehicle as it sped down the highway between two equally flat horizons, saw clouds the color of boiling slate materialize from a chalk-blue sky.

"We'll need to get under cover again," she heard Turk say.

To the southwest Turk could just make out the silver-black silhouettes of the Aramco drilling and pumping complex. Evacuated, presumably—a couple of the far towers seemed to be leaning off vertical, though that could be an illusion—but Turk guessed the site would still be guarded, both by machines and by armed men.

Fortunately they didn't need to head in that direction. The oil concessions had grown a ring of commerce around them, businesses run by lonely men for lonely men, strip clubs and bars and porn vendors, which meant that not far down the road they would find more respectable commercial concessions and housing for the hired workers. Which appeared as the two cars raced the black cloud flowing from the east: a gated side road, the gate unchained; a mall (grocery store, media retailers, a multi-mart); and a number of sturdy concrete buildings in which one- or two-room utility apartments were stacked like boxes.

Turk, in the lead car with Lise and Dr. Dvali, looked back and saw the second vehicle pulling into the mall lot. Dvali swung around and intercepted them in front of the grocer)? store.

"Supplies," Diane explained.

"We don't have time," Dvali said sternly. "We need to get under cover."

"Such as the building up ahead? I would suggest you break in or whatever you need to do, and we'll follow as soon as we find food."

Dvali clearly didn't like this idea, but just as clearly, Turk thought, it made sense: they had been running low on essentials and the ash storm might maroon them for a good long time. "Be quick about it," Dvali said unhappily.

Whoever designed this workers' barracks had made no attempt to disguise the institutional nature of the project. On the outside the building was weathered concrete and cracked pavement and an empty parking lot adjoining a tennis court enclosed in a chain-link fence, its net slumped in disarray. The door Turk approached was hollow steel painted industrial yellow, no doubt battered by the boots of hundreds of shit-drunk oil-riggers over the years, and it was locked, but the lock was fragile and gave way after some leverage with a tire-iron. Dvali fidgeted while Turk performed this task, glancing back at the approaching storm. The light was thinning already, the disc of the sun growing weak and obscure.

The door sprang loose and Turk stepped into the interior darkness, followed by Dr. Dvali and finally Lise.
