It was Alita, working from the Arctic with the raw data Swan had transmitted the moment the room had gone quiet enough to spare the bandwidth, who found the thread that mattered most before the shuttle had even begun its return crossing, her voice carrying, over the comm, the particular focused urgency of someone who had found something and did not want to wait even the few minutes it would take to say it in person.
"The station's old visitor log," she said. "It's not networked to anything current, which is exactly why it survived. Swan's data dump included a partial capture from an automated access terminal near the vault door, the kind that logs an authorization attempt whether or not it succeeds. There's an entry from roughly six weeks ago. A failed attempt to remotely trigger the vault's outer seal, using a genuine Fleet clearance key, command-track schema."
"Which of the three," Taisen said, quiet, feeling the whole room's attention settle on the comm.
"That's the part I need to be careful about," Alita said, "because the schema alone doesn't name a person, it names a category, and I don't want to hand you a name dressed up as more certain than it actually is. Command-track override keys, the kind that can even attempt to trigger a vault seal remotely, are only issued to Fleet Marshal-level staff and their direct adjutants. Logistics chiefs carry a different schema entirely, tied to supply authorization rather than command override. Comm clerks carry a third schema again, tied to message routing, nothing close to what this attempt used."
The comm held a long, weighted silence.
"That rules out Farrow," Swan said finally, working it through aloud. "Her access never had the tier to even attempt this, whoever she actually is."
"It does," Alita agreed. "It doesn't clear Anand entirely, because logistics chiefs occasionally hold emergency override keys for exactly the kind of crisis authorization that could plausibly be stretched to cover something like this, if she was resourceful enough and desperate enough to misuse it. But it points hardest at Oyelaran. Command-track schema, six years as Zhang's adjutant, access to exactly this kind of clearance as a matter of routine rather than exception. I'm not telling you it's confirmed. I'm telling you it's the strongest lean any of us have found yet, and it's earned, not guessed, straight out of a log system old enough that nobody currently watching Fleet's networks would have thought to touch it."
Taisen was quiet a long moment, turning the new shape of the suspect list over in his mind with his usual unhurried care, honest with himself even when the honesty cost him something.
"Three becomes two, weighted toward one," he said finally. "Send everything to Zhang's relay the moment we're back aboard. Every piece of it, plainly, with exactly the uncertainty you just gave me and not a shade more confidence than that. I'd rather he watch Oyelaran harder starting tonight than wait for a certainty that might never fully arrive."
Camaro, listening from her position at the door, said nothing for a moment, and when she finally spoke, there was a weight in it that hadn't been there a moment before. "Six years grooming his own successor," she said. "Zhang said that himself, in his own message. If it's Oyelaran, that's not a stranger who slipped past a careless man's guard. That's a man who spent six years being trusted with everything, deciding somewhere along the way that trust was worth selling."
"We don't know that yet," Taisen said. "I want to be careful about how far ahead of the evidence any of us lets our own certainty run tonight, myself included. A lean isn't a verdict. I've watched good men hang an innocent officer's career on considerably less than what Alita just gave us, and I don't intend to let this crew make that same mistake, however satisfying it might feel to finally have a name to be angry at."
"Understood," Camaro said, though something in her face suggested the caution cost her more than she let show.
Lyn, who had come to stand at the edge of the small compartment sometime during the exchange, arms folded, listened to the last of it in silence before adding her own weight to the room. "I want it said plainly, for the record," she said, "that if it is him, Zhang's going to have to be the one who moves on it. Not us. We're not standing anywhere near the chain of command that could act on this cleanly, and the moment we try to act on it ourselves from outside that chain, we become exactly the kind of rogue element Fleet Command would use to discredit the whole finding, whether it's true or not."
"Agreed," Taisen said. "We hand him the thread. We don't pull it ourselves."
Alita composed the message herself once the shuttle had cleared the docking collar and the archive terminal was hers again to work from properly, choosing each word with the same deliberate care Taisen had used composing his own message before Corvid's Rest, reading it back to herself twice before she let it go, because she understood, better than most people her age would have, exactly how much a single misjudged word could cost a man three relay hops away with nobody left to trust but the voice arriving out of the dark.
Marshal. We found the file. Cold Hearth traces to Calder's Reach, an old observatory holding what's left of a survey your own three visits were quietly circling. We have reason, earned from records that predate anything currently connected to Fleet's own networks, to weight suspicion more heavily toward Colonel Oyelaran than the other two names. I want to be precise about the word I'm using. Weight, not proof. The schema of the access key used doesn't clear Commodore Anand entirely, and it rules Sergeant Farrow out almost completely. We are not asking you to act on a lean. We are asking you to watch more closely where the evidence currently points, and to be careful doing it, because whoever's behind this has already shown they notice when they're being watched back.
There is more here than a leak, Marshal. There is a weapon at the center of it, and it is not a rumor. Krell agents are already circling the same fire we are. Watch your circle, and watch your own back the same way. We are not done pulling this thread, and neither, I suspect, is whoever's on the other end of it.
