All she has to do is step outside.

She sits in her cubby, and doesn't move.

Gravediggers

Find the damn mines.

They spread out across the territory like black dogs, sniffing through light and shadow with sonar pistols and flux detectors. Some of them may question the exercise—and some of them almost certainly root for its failure—but nobody still alive after five years down here is going to be dumb enough to go all insubordinate on Ken Lubin.

Find the damn mines.

Clarke glides among them, just another nose on the trail as far as anyone can tell. Hers is not so focused, though. The others follow invisible lines, the threads of a systematic grid laid down across the search area; but Clarke zigzags, coasts down to accompany this compatriot or that, exchanging insignificant bits of conversation and intel before diverging courses in search of new company. Clarke has a different mission.

Find the damn mine-layer.

Hectares of biosteel. Intermittent punctuations of light and shadow. Flashing staccatos at each extremity, little blinking beacons that announce the tips of scaffolds, antennae, danger zones where hot fluids might vent without warning. The baleful, unwavering glare of floodlights around airlocks and docking hatches and loading bays, reignited for today's exercise. Pale auras of wasted light from a hundred parabolic viewports. Twilit expanses of hull where every protuberance casts three or four shadows, dimly lit by lamps installed in more distant and glamorous neighborhoods.

Everywhere else, darkness. Elongated grids of shadow laid out by naked support struts. Impenetrable inky pools filling the spaces between keel and substrate, as though Atlantis were some great bed with its own scary place for monsters lying beneath. Fuzzy darkness where the light simply attenuates and fades; or razor-sharp where some tank or conduit extends into bright sodium sunlight, laying inky shadows over whatever lies beneath.

More than enough topography to hide an explosive device barely twice the size of a man's hand. More than enough to hide a thousand.
