A sea of mist drifted through the cloud forest: soft, grey, luminescent. On the high ridges the fog showed brighter as the morning sun began to warm and lift the moisture, although in the ravine a cool, soundless dimness still counterfeited a pre-dawn twilight.

Commander Cordelia Naismith glanced at her team botanist and adjusted the straps of her biological collecting equipment a bit more comfortably before continuing her breathless climb. She pushed a long tendril of fog-dampened copper hair out of her eyes, clawing it impatiently toward the clasp at the nape of her neck. Their next survey area would definitely be at a lower altitude. The gravity of this planet was slightly lower than their home world of Beta Colony, but it did not quite make up for the physiological strain imposed by the thin mountain air.

Denser vegetation marked the upper boundary of the forest patch. Following the splashy path of the ravine's brook, they bent and scrambled through the living tunnel, then broke into the open air.

A morning breeze was ribboning away the last of the fog on the golden uplands. They stretched endlessly, rise after rise, culminating at last in the great grey shoulders of a central peak crowned by glittering ice. This world's sun shone in the deep turquoise sky giving an overwhelming richness to the golden grasses, tiny flowers, tussocks of a silvery plant like powdered lace dotted everywhere. The two explorers gazed entranced at the mountain above, enveloped by the silence.

The botanist, Ensign Dubauer, grinned over his shoulder at Cordelia and fell to his knees beside one of the silvery tussocks. She strolled to the nearest rise for a look at the panorama behind them. The patchy forest grew denser down the gentle slopes. Five hundred meters below, banks of clouds stretched like a white sea to the horizon. Far to the west, their mountain's smaller sister just broke through the updraft-curdled tops.

Cordelia was just wishing herself on the plains below, to see the novelty of water falling from the sky, when she was jarred from her reverie. "Now what the devil can Rosemont be burning to make a stink like that?" she murmured.

An oily black column of smoke was rising beyond the next spur of the mountain slope, to be smudged, thinned, and dissipated by the upper breezes. It certainly appeared to be coming from the location of their base camp. She studied it intently.

A distant whining, rising to a howl, pierced the silence. Their planetary shuttle burst from behind the ridge and boomed across the sky above them, leaving a sparkling trail of ionized gases.

"What a takeoff!" cried Dubauer, his attention wrenched skyward.

Cordelia keyed her short-range wrist communicator and spoke into it. "Naismith to Base One. Come in, please."

A small, empty hiss was her sole reply. She called again, twice, with the same result. Ensign Dubauer hovered anxiously at her elbow.

"Try yours," she said. But his luck was no better. "Pack up your stuff, we're going back to camp," she ordered. "Double time."

They struggled toward the next ridge at a gasping jog, and plunged back into the forest. The spindly bearded trees at this altitude were often fallen, tangled. They had seemed artistically wild on the way up; on the way down they made a menacing obstacle course. Cordelia's mind ratcheted over a dozen possible disasters, each more bizarre than the last. So the unknown breeds dragons in map margins, she reflected, and suppressed her panic.

They slid down through the last patch of woods for their first clear view of the large glade selected for their primary base camp. Cordelia gaped, shocked. Reality had surpassed imagination.

Smoke was rising from five slagged and lumpy black mounds, formerly a neat ring of tents. A smouldering scar was burned in the grasses where the shuttle had been parked, opposite the camp from the ravine. Smashed equipment was scattered everywhere. Their bacteriologically sealed sanitary facilities had been just downslope; yes, she saw, even the privy had been torched.

"My God," breathed Ensign Dubauer, and started forward like a sleepwalker. Cordelia collared him.

"Get down and cover me," she ordered, then walked cautiously toward the silent ruins.

The grass all around the camp was trampled and churned. Her stunned mind struggled to account for the carnage. Previously undetected aborigines? No, nothing short of a plasma arc could have melted the fabric of their tents. The long-looked-for but still undiscovered advanced aliens? Perhaps some unexpected disease outbreak, not forestalled by their month-long robotic microbiological survey and immunizations—could it have been an attempt at sterilization? An attack by some other planetary government? Their attackers could scarcely have come through the same wormhole exit they had discovered, still, they had only mapped about ten percent of the volume of space within a light—month of this system. Aliens?

She was miserably conscious of her mind coming full circle, like one of her team zoologist's captive animals racing frantically in an exercise wheel. She poked grimly through the rubbish for some clue.

She found it in the high grass halfway to the ravine.

The long body in the baggy tan fatigues of the Betan Astronomical Survey was stretched out full length, arms and legs askew, as though hit while running for the shelter of the forest. Her breath drew inward in pain of recognition. She turned him over gently.

It was the conscientious Lieutenant Rosemont. His eyes were glazed and fixed and somehow worried, as though they still held a mirror to his spirit. She closed them for him.

She searched him for the cause of his death. No blood, no burns, no broken bones—her long white fingers probed his scalp. The skin beneath his blond hair was blistered, the telltale signature of a nerve disruptor. That let out aliens. She cradled his head in her lap a moment, stroking his familiar features helplessly, like a blind woman. No time now for mourning.

She returned to the blackened ring on her hands and knees, and began to search through the mess for comm equipment. The attackers had been quite thorough in that department, the twisted lumps of plastic and metal she found testified. Much valuable equipment seemed to be missing altogether.

There was a rustle in the grass. She snapped her stun gun to the aim and froze. The tense face of Ensign Dubauer pushed through the straw-colored vegetation.

"It's me, don't shoot," he called in a strangled tone meant to be a whisper.

"I almost did. Why didn't you stay put?" she hissed back. "Never mind, help me look for a comm unit that can reach the ship. And stay down, they could come back at any time."

"Who could? Who did this?"

"Multiple choice, take your pick—Nuovo Brasilians, Barrayarans, Cetagandans, could be any of that crowd. Reg Rosemont's dead. Nerve disruptor."

Cordelia crawled over to the mound of the specimen tent and carefully considered its lumps. "Hand me that pole over there," she whispered.

She poked tentatively at the most probable hump. The tents had stopped smoking, but waves of heat still rose from them to beat upon her face like the summer sun of home. The tortured fabric flaked away like charred paper. She hooked the pole over a half-melted cabinet and dragged it into the open. The bottom drawer was unmelted, but badly warped and, as she found when she wrapped her shirttail around her hand and pulled, tightly stuck.

A few minutes more search turned up some dubious substitutes for a hammer and chisel: a flat shard of metal and a heavy lump she recognized sadly as having once been a delicate and very expensive meterological recorder. With these caveman's tools and some brute force from Dubauer, they wrenched the drawer open with a noise like a pistol shot that made them both jump.
