Flag In Exile

don't you?'

'A minor talent, Ma'am,' he said equally softly, and freed his other hand from the bottle to cover hers. Then he stepped back and set the bottle on the tray. 'Buzz if you need anything else, Milady,' he said with a small, formal bow, and withdrew from the cabin.

Honor watched him go, then turned tack to Gerrick and LaFollet. The armsman stood formally beside her chair, but she shook her head and pointed to the couch. He hesitated a moment, then drew a deep breath, nodded, and obeyed her gesture, and she waited for him to settle before she looked back at Gerrick.

'Tell me,' she commanded, and her voice was hers again. Still strained with grief and pain, but hers.

'In a sense, My Lady, it was our fault,' Gerrick said quietly, 'but only because we let the bas...' He paused, as if his anger had finally cooled enough for him to remember his language, then went on. 'Only because we let whoever planned this slip their own people into our workforce, My Lady.' He shrugged. 'It never occurred to us that anyone might deliberately cause a disaster like this. We were only concerned with getting people who could do the job and then training them to do it right; security measures against sabotage never even crossed our minds.'

'There was no reason they should have, My Lady,' LaFollet said, and she glanced at him. 'Oh, in hindsight, yes, it's something you ought to have considered. But hindsight is always perfect, and going in, there was no more reason for you to think any of your employees were mass murderers than for any other company to worry about it.'

Honor nodded, grateful for his reassurance but not really needing it, not now, and looked back at Gerrick.

'Major LaFollet’s right, My Lady, and this was no case of an individual maniac, either. It took at least eighteen or twenty people, acting in concert, to pull this off. That makes it a conspiracy, as well as murder.'

'How did they do it?' she asked.

'They had two strings to their bow,' Gerrick replied.

'Either of them might have done it alone; with both of them in place, I'm amazed we got as far as we did before the dome collapsed.' The engineer made a little face, and if his voice was no less angry, it was also dry and factual when he continued.

'One of their people got himself hired as a power bore operator, My Lady, and he altered the profile on the holes he drilled to hold the main support units. You're familiar with the original design?'

'Only in general terms,' Honor said. She'd examined the plans, but they hadn't been her area of expertise.

'Do you remember how we'd designed the holes to give the maximum volume for the ceramacrete footings while simultaneously locking the base of each support into a natural load-bearing matrix?' Gerrick asked, and she nodded. 'Well, with the supports socketed into the crosscuts and a hundred-plus tons of ceramacrete poured into each footing on top of that, each support in the alpha ring should have been the next best thing to indestructible.'

Honor nodded. Had the ceramacrete been properly fused, it would have formed the equivalent of a plug of solid igneous rock stronger and harder than obsidian. Coupled with the socketing effect of the crosscuts, the support members should have been like extrusions of the planet's very bones.

'All right, My Lady, what actually happened is this. When the man on the power bore drilled his holes, they looked close to specs, but the portion that was supposed to 'neck down' actually had a diameter equal to the support's width, which meant the beams didn't engage in the crosscuts and knocked out that part of the design's stress redundancy. We've only managed to check two of the holes, since the Mueller inspectors won't let us on-site, but we had good visual records on those two. The people who shot the chips were holo-vid techs, not engineers, so they never noticed the proportions were off, and none of our technical people viewed the chips prior to the accident. But we've viewed them now, and we've been able to scale the holes from the HD chips. It's a computer reconstruction, but it'll stand up in any court, and the holes themselves are still there and available for physical examination to confirm it.'

Honor nodded once more, and Gerrick rubbed his eyebrow in a gesture of tired triumph before he continued.

'In addition to the diameter shift, the bottoms of each of the holes we've checked were also off profile, My Lady. They were cut on a slight angle, so that only the edge of each support actually had any bearing surface. Again, with good ceramacrete, that wouldn't have mattered, since the pour would have come in under the unsupported portion of each upright before it was fused. With bad ceramacrete, it became an important factor in what happened.'

'Didn't we check the profiles?'

'Yes and no, My Lady,' Gerrick said with a grimace. 'The specs were locked into the bores' software. For them to be off required the bore operator to deliberately alter them, and we run diagnostics and self-check programs on all our equipment between shifts to catch any accidental modifications. That meant whoever altered them also had to reset them before he went off shift, which he did. That deprived us of any warning from that end... and, just incidentally, proves that what happened wasn't an accident.

'But we had a second built-in check, My Lady. The crews who set the supports also had the proper profiles in their software. If the holes were off, they should have caught them, would have caught them, if they hadn't been deliberately covering for whoever drilled them in the first place. That's how we know there were at least two teams involved in this. And, finally, we had on-site supervisors who were responsible for spot-checking the footings after they were in. But the point is that we were checking for accidents, not deliberate sabotage, and whoever planned this knew it.

'As nearly as we can piece it together at this point, the crews who put the supports into the bad holes knew which ones were off. They put in their beams, then poured the ceramacrete, but they only fused the top half meter or so of it. Two of the bad holes had good ceramacrete, so we're assuming one of our supervisors happened by during those pours and that the saboteurs were afraid to hold back on the fusing process in his presence because they figured he'd spot it. As far as the others are concerned, though, our inspectors, and the Mueller Steading inspectors, for that matter, only drill twenty-centimeter cores for our quality control samples. That's the standard for Sword and steading inspectors, My Lady, partly because it's so hard to drill through ceramacrete in the first place. Given what's happened here, however, I've already recommended to the Protector that the requirement be changed to a full-depth sampling technique.

'What it meant, though, was that a half-meter of good ceramacrete gave a valid quality control check for the entire footing, a footing which, in fact, came nowhere close to meeting the stress loading we'd designed into it. In fact, it wouldn't have been enough to handle the loads in a good hole, but they weren't taking any chances.'

The engineer paused with a bitter smile, then took another sip of his wine and leaned back in his chair.

'So what happened, My Lady, is that approximately fourteen percent of the main load-bearing elements of the dome had been designed to fail, and the angle cut into the bottom of each hole actually threw the mass of those supports against the other elements of the dome. There was no way, My Lady, no way at all, that dome was going to stand with that kind of bugger factor built into it, and whoever did it knew exactly what was going to happen.'

'Who, Adam.' Honor's eyes were hard, and the engineer shrugged.

'At this point, My Lady, we're still figuring out exactly how they did it. We can't identify the crews who set the supports and poured the ceramacrete from our own work orders, but Security is working with the site visual records, and Lord Clinkscales fully expects to find their faces in our employee database. But we can positively identify the bore operator right now, because we know which bore drilled which holes and who was the assigned operator on each bore.'

'And?'

'According to our records, it was a Lawrence Maguire, My Lady,' Gerrick said flatly. 'He's one of the workers who 'resigned in protest' when the first reports of substandard materials came out, and we don't know
