"What we think most likely happened is that two separate sequences of events crossed each other. Jack, trying to defect with Simões, decided he was being doublecrossed. So, he planned to destroy Cachat and Zilwicki in a manner that would eliminate any trace of them, any evidence that could connect him to them. He'd figure we'd assume the Buenaventura explosion was an act of terrorism by the Audubon ballroom. Don't forget, he had a perfectly reasonable explanation for being in Gamma Center that day, with Simões. It had been on his calendar for at least two weeks. In fact, he'd specifically memoed Isabel about it."
"And the surviving Gamma Center records confirm that's where the two of them were?" Benjamin's tone made the question a statement, and Collin nodded.
"Exactly. And, before you ask, Father, no, I can't be absolutely certain that the records which show Simões was there also weren't somehow faked. It wouldn't have been as hard for Jack to successfully fake those records as it would've been for Zilwicki to do the same thing at the Buenaventura, but why should he have? There's no way he himself wasn't present when he destroyed the Gamma Center. That much we know for certain, because Scorched Earth had to be triggered by someone inside the facility. It can't—couldn't—be done by remote control."
He scowled.
"In fact, it wasn't supposed to be possible for Scorched Earth to be triggered by any single person, either, no matter where they were. Trust me, some people have already . . . heard from me about that one. Jack figured out a way to circumvent the two-man protocols, and nobody was supposed to be able to do that."
"So you're assuming McBryde didn't find out about the doublecross until he and Simões had already met in his office," Albert said.
"Yes, and that's where the second sequence of events comes into play. What Jack overlooked—probably because he'd been out of the field long enough for his fieldcraft to get rusty—was the possibility that Irvine might have set up his own surveillance equipment and spotted him meeting Zilwicki. Irvine didn't recognize Zilwicki as Zilwicki because we hadn't spread that information far enough down the chain for him to have any idea what Zilwicki actually looked like. But he did understand that something fishy was going on, so he alerted Isabel. He got through to her on the same morning Jack's negotiations with Zilwicki and Cachat collapsed, and she went down to the Gamma Center to find out just what the hell Jack was up to."
"In other words, it was just really bad timing from McBryde's point of view," Albert mused. "He'd probably have gotten away with killing Cachat and Zilwicki, and he must've had plans for dealing with Simões, too, in the event that his defection fell through. But then Isabel showed up out of the blue, and he realized the wheels had come completely off. There was no way he was going to get away with it, and he knew what the penalty would be, so he committed suicide and took out Cachat and Zilwicki at the same time."
"That's the consensus," Collin confirmed. But Benjamin, who'd been studying his brother closely through the previous explanation, cocked his head.
"Why do I get the feeling you don't agree with that consensus, Collin? Or not fully, at least?"
"Hard to keep secrets between us, isn't it?" Collin gave him a wry smile. "You get that feeling because it's true. I think there's another explanation, one that's more likely, given the principals. But I'll also add that no one else on my team agrees with me, and it's possible I'm being sentimental."
His father had been studying him carefully, as well. Now Albrecht leaned forward slightly, propping one elbow on his desk.
"You think McBryde had a last-minute change of heart," he said softly.
"Not . . . exactly." Collin frowned. "The thing is, I knew Jack McBryde. We worked together for years, and one of Jack's best qualities was that he wasn't vindictive in the least. In fact, probably less vindictive than almost anyone I can imagine. That's one of the reasons he was so popular with his subordinates. Jack would discipline people, when it was necessary. Sometimes even harshly. But never more harshly than was necessary, and never out of anger. I've seen him mad, plenty of times, but it never came out in the way he treated other people. On the other hand . . ."
"He was squeamish."
"Yes, Father." Collin sighed. "It was his biggest weakness, frankly. In fact, it was the reason I had him assigned to Gamma Center originally. Or, rather, the reason I had his permanent file quietly tagged 'not for field ops' and moved him over to the security side in the first place."
"I don't see where you're going with this," Benjamin said with a slight frown.
"I do," Albrecht said. "Why would an overly softhearted person with no history of vindictiveness or vengefulness kill—how many people was it, Collin?"
"As I say, we're figuring a minimum of thirty or forty for the Buenaventura explosion. Personally, I think it was probably close to twice that many, if you count the unregistered seccies who were probably caught in it, as well. We can add another sixty for the Gamma Center—even on a Saturday—even before we count Isabel, her team, and Jack itself."
"But that's not really the point," his father said, looking back at Benjamin. "The people inside the Center were unavoidable collateral damage once he decided on Scorched Earth. But we're talking about a minimum of more than three dozen people—quite possibly a lot more—in a separate explosion he didn't have to set off." Albrecht raised an eyebrow. "Now do you see? Some compulsion had to drive McBryde to overcome his scruples. And if it wasn't vengeance, what was it? What Collin is suggesting is that once it became clear to McBryde that his plans to defect had been aborted and he was going to die, he saw to it that Zilwicki and Cachat died also—and before they got off-planet with whatever he might have given them. As a last act of . . . what would you call it, Collin? Patriotism seems a little silly."
"More like . . . atonement, I think. Keep in mind that I can't prove any of this, Father. It's just my gut feeling. And, as I said, no one else on my team agrees with me."
"Practically speaking, though, it doesn't really matter which explanation actually applies, does it?" Albrecht asked gently, almost compassionately.
"No, Sir. It doesn't," Collin agreed a bit softly.
"And the Park explosion?"
"That one's still something of a puzzle," Collin confessed, and his eyes darkened once more. "I don't like admitting that, either, given how many of my neighbors were killed. The current casualty total for that one is around eight thousand, though, and I'm damned sure Jack McBryde didn't have anything to do with that! At the same time, I don't think I believe somebody would just 'coincidentally' pick that particular day to set off a nuclear charge in a completely separate, spontaneous terrorist incident."
"So you think they're related?"
"Father, I'm sure they have to be related somehow. We just don't know how. And we don't know—and will never know—who actually detonated the damned thing. We've got the feed transmitted from those two cops' HD cams, but neither camera ever had a good angle on the driver's face, so there's no way we can tell if whoever it was was ever in our files. Or, perhaps, I should say in our surviving files." His smile could have curdled milk. "It's possible—even probable—he was Ballroom affiliated, but we can't prove that. I'm inclined to think he was a seccy, not a slave, but that's really as far as I am prepared to go."
He shrugged, much more lightly—obviously—than he actually felt.
"What I don't understand, even assuming he was Ballroom connected, is why. I'm assuming that, with Zilwicki's own Ballroom connections, he was receiving support from assets of theirs here on Mesa, as well. We keep them prunded far enough back that they don't have a truly effective presence—or we think we do, at any rate; what happened with Jack could prove we've been a little over sanguine in that respect. But even pruned back, they've always had some contacts among the seccies, and I think we have to take it for a given that Zilwicki had tapped into them for assistance once he got here. So my first hypotheses was that this was intended as a diversion for his and Cachat's escape. And," his eyes hardened and his voice went grim, "it would have made one hell of a diversion. Eight thousand dead and another sixty-three hundred badly injured?" He shook his head. "It had every emergency responder in the city—and from Mendel, too, for that matter!—racing in one direction, and you couldn't have asked for a better diversion than that.
