He lifted his cuff, ready to call his deputy, fearing the worst. But he had not even uttered Sparver’s name before his console informed him that there had been a major incident in the Turbine hall.
Dreyfus stepped through his clotheswall and made his way from his room through the warrens of the rock to the non-centrifuge section where the Search Turbines were located. Even before he arrived, he realised that the incident had been grave. Prefects, technicians and machines were rushing past him. By the time he reached the entrance to the free-fall hall, medical crews were bringing out the wounded. Their injuries were shocking.
A conveyor band drew him into the vastness of the hall. He stared in stupefied amazement at the spectacle. There were no longer four Search Turbines, but three. The endmost cylinder was gone, save for the sleeve-like anchor points where it emerged from the chamber’s inner surface. The transparent shrouding had shattered into countless dagger-like shards, many of which were now embedded in the walling. Dreyfus couldn’t imagine the outward force that would have been necessary to rupture the armoured sheathing, which was the same kind of glass-like substance they used to form spacecraft hulls. As for the machinery that would have been whirling inside the glass just before it broke loose, nothing remained except a dusty residue, lathered several centimetres thick over every surface and hanging in the air in a choking blue-grey smog. The Turbine—its layered data stacks and whisking retrieval blades—had pulverised itself efficiently, leaving no components larger than a speck of grit. It was designed to do that, Dreyfus reminded himself, so that no information could be recovered by hostile parties in the event of a takeover of Panoply. But it was not meant to self-destruct during the course of normal operations.
He studied the other Turbines. The sheathing on the nearest of the three, the one that had been closest to the destroyed unit, was riven by several prominent cracks. The apparatus inside was spinning down, decelerating visibly. The other two units were undergoing the same failsafe shutdown, even though their casings appeared intact.
Keeping out of the way of the medical staff attending to hall technicians who’d been lacerated by glass and high-speed Turbine shrapnel—they’d already pulled out the most seriously wounded—Dreyfus found his way to a woman named Trajanova. She was the prefect in charge of archives, and considered supremely competent by all concerned. Dreyfus did not dissent from that view, but he did not like Trajanova and he knew that the feeling was mutual. He’d employed her once as a deputy, then dismissed her because she did not have the necessary instincts for fieldwork. She had never forgiven him for that and their rare meetings were tense, terse affairs. Dreyfus was nevertheless relieved to see that she had suffered no conspicuous injuries save for a gashed cheek. She was pressing her sleeve to it, her uniform dispensing disinfectant and coagulant agents. She had headphones lowered around her neck, glasses pushed up over her brow and a fine dusting of blue-grey debris on her clothes and skin.
Trajanova must have seen the look on his face.
“Before you ask, I have no idea what just happened.”
“I was about to ask if you were all right. Were you in here when it happened?”
“Behind the fourth stack, the furthest one from the unit that blew. Running search-speed diagnostics.”
“And?”
“It just went. One second it was spinning, next second it didn’t exist any more. I’d have been deafened if I hadn’t had the phones on.”
“You were lucky.”
She scowled, pulling her sleeve away to reveal the dried blood on her cuff.
“Funny. I’d say it was fairly unlucky of me to have been in here in the first place.”
“Was anyone killed?”
“I don’t think so. Not permanently.” She rubbed at dust-irritated eyes.
“It was a mess, though. The glass did the worst harm. That’s hyperdiamond, Dreyfus. It takes a lot to make it shatter. It was like a bomb going off in here.”
“Was it a bomb? I mean, seriously: could a bomb have caused this?”
She shook her head.
“I don’t think so. The unit just spun loose, all of a sudden. There was no bang, no flash, before it happened.”
“Those things run near critical break-up speed, don’t they?”
“That’s the idea. We spin them as fast as they can go. Any slower and you’d be the first to moan about retrieval lag.”
“Could the unit have overspun?” She answered his question with look of flat denial.
“They don’t do that.”
“Could the assembly have been fatigued?”
“All the units are subjected to routine de-spin and maintenance, one at a time. You don’t usually notice because we take the burden on the other three Turbs. The unit that failed got a clean bill of health during the last spin-down.”
“You’re sure of that?” Her face said: Don’t question my competence, and I won’t question yours.
“If it hadn’t, it wouldn’t be spinning, Prefect.”
“I had to ask. Something went terribly wrong here. Could a badly formed query have caused the break-up?”
“That’s a bizarre question.”
“It’s just that I sent something through about a second before the accident.”
“The units would have handled millions of queries in that interval,” she said.
“Millions? There aren’t millions of prefects.”
“Most of the queries coming through are machine-generated. Panoply talking to itself, consolidating its own knowledge base. The Turbs don’t care whether it’s a human or a machine sending the query. All are treated with equal priority.”
“It still felt related to me.”
“It can’t have been your query that did this. That would be absurd.”
“Maybe so. But I’m conducting a sensitive investigation and just at the point when I think I’m getting somewhere, when I might be about to connect my case to one of our glorious families, when I might be about to hurt someone, one of my primary investigative tools is sabotaged.”
“Whatever this was, it can’t have been sabotage,” Trajanova said.
“You sound very certain.”
“Maybe it’s escaped your attention, but this is an ultra-secure facility inside what is already an ultra-secure organisation. No one gets inside this room without at least Pangolin clearance, and no one—not even the supreme prefect herself—gets to access the Search Turbines from outside the rock. Frankly, I can’t think of a facility it would be harder to sabotage.”
“But a prefect could do it,” he said.
“Especially if they had Pangolin clearance.”
“I was keeping our discussion within the realms of possibility,” Trajanova said.
“I can think of a million reasons why our enemies might want to smash the Search Turbines. But a prefect, someone already inside the organisation? You mean a traitor?”
“I’m just running through the possibilities. It’s not so very difficult to believe, is it?”
“I suppose not,” Trajanova said slowly, staring him hard in the eye.
“After all, there’s a traitor’s daughter in the organisation even as we speak. Have you talked to her recently?”
“With Thalia Ng? No, she’s too busy acquitting herself excellently on field duties.” He smiled coldly.
“I think we’re done here, aren’t we?”
“Unless you want to help me clean up this mess.”
“I’ll leave that to the specialists. How long before we’ll have the other Turbs back up to speed?” She glanced over her shoulder at the intact tubes.
“They’ll have to be thoroughly checked for stress flaws. Thirteen hours, at the very minimum, before I’ll risk spin-up. Even then we’ll be running at a low retrieval rate. Sorry if that inconveniences you, Prefect.”
