Chapter 68: Mole Hunt

"Start with what we know," Kira said from the med bay cot. Her datapad was propped on her knees. The headache was a dull roar behind her eyes, but her thinking was sharp—the inflammation hadn't reached the parts of her brain responsible for paranoia, and right now paranoia was exactly what she needed. "Kaine sent a coded transmission aimed at this station. MI-level encryption. Someone here has a receiver."

Cross stood at the foot of the cot. Jax leaned against the wall by the door. Aria-7's voice came through the room's speaker, the AI running signal analysis in parallel with the conversation.

"The transmission was tight-beam," Aria-7 said. "Directional, aimed at the station's coordinates. However, the frequency used is compatible with any standard personal communications device manufactured within the last fifteen years. The receiver could be a dedicated MI unit or a modified civilian device with the correct decryption key loaded."

"How many personal comm devices are on this station?" Kira asked.

"Approximately one hundred and sixty-three. Every person aboard carries at least one. Some carry two."

One hundred and sixty-three devices. Any of which could be the receiver.

"We can't search them all," Jax said. His voice was level. The formal cadence—the register he defaulted to when the situation was tactical and personal feelings were a liability. "The refugees would panic. The *Talon's* crew would interpret it as distrust. We would damage the relationships we've built in three days of work."

"Agreed," Cross said. "A mass search is counterproductive. We need to narrow the field."

Kira looked at the datapad. The station's population, broken into groups. Forty-seven Meridian refugees. Sixty-three *Talon* crew. Thirty-one marine prisoners—now thirty, with Arun moved to intelligence work. The station's original crew of twelve. Kira's crew. Cross.

"The marine prisoners," Kira said. "They were searched on capture. Weapons confiscated."

"Personal items were not confiscated," Jax said. "Standard convention protocols. Personal communications devices, identification, non-weapon items—all retained. The marines have their comms."

"Then any of the thirty prisoners could be receiving."

"Correct. However—" Jax's cybernetic arm whirred. The subtle sound it made when he was processing something that bothered him. "The prisoners are in the cargo bay. Under guard. Their movements are restricted. If one of them received a coded transmission, they would have no way to respond without being observed by the guards or by Aria-7's communications monitoring."

"Unless the device is configured for passive reception only," Cross said. "Receive but do not transmit. A listening post. The spy receives instructions from Kaine but sends reports through a different method—or has already sent everything Kaine needs before the fleet withdrew."

The med bay was quiet. The warship's amber hum. The recycled air.

"The refugees," Kira said. "Forty-seven people from Meridian Station. We don't know any of them. We don't know their backgrounds, their histories, their connections. If the Emperor wanted to plant an agent—"

"A refugee transport arriving at a station under siege would be an ideal insertion method," Cross finished. "The chaos of processing, the sympathy for displaced civilians, the practical need to accommodate newcomers—all of it provides cover."

Kira looked at Jax. "Can you search the refugee quarters without being obvious about it?"

"Not obvious, no. I can conduct a safety inspection—checking for unsecured power connections, environmental hazards, the kind of routine sweep that a first mate performs on a station with new occupants." Jax paused. "But MI devices are designed to be concealed. If the agent is competent, their equipment will look like personal items. A modified datapad. A jewelry piece with embedded circuitry. A medical device with secondary function."

"Do it anyway. And the *Talon's* crew quarters."

"Drayden will notice."

"Let her notice. Tell her we're doing a safety check on all occupied spaces. She's military—she'll understand the routine."

Jax nodded. Left.

---

The search took four hours and found nothing.

Jax was thorough. The refugee section on Level Four—forty-seven bunks, forty-seven sets of personal belongings, most of them pathetically small. A change of clothes. A family photo. A child's toy. The portable accumulation of lives interrupted. He checked each space with the methodical care of a man who'd conducted a thousand barracks inspections, looking for the tell—the device that didn't belong, the item that was too new or too well-maintained for a refugee's kit.

Nothing. Or rather—nothing he could identify. MI concealment was good. If there was a device in the refugee section, it was disguised well enough to pass a visual inspection, and Jax wasn't going to start cracking open personal items to run electronic scans. Not without more evidence. Not without burning every bridge they'd built with people who'd come to them for safety.

The *Talon's* crew spaces were cleaner. Military quarters. Organized. Drayden had her people running a tight operation—the crew quarters were arranged by rank and division, personal items stowed in regulation lockers, the spaces maintained to Imperial standards despite the fact that they'd defected from the fleet three days ago. Old habits.

Jax found nothing there either. Drayden watched him conduct the inspection from the corridor, her arms crossed, her expression the careful blankness of a woman who knew this wasn't a safety check and was choosing not to challenge it.

"Anything?" she asked when he finished.

"Environmental systems are functioning properly in all occupied spaces," Jax said. The formal answer. The cover story, maintained for the corridor surveillance.

Drayden looked at him. Three seconds.

"If you need to ask me something, Reyes, ask it."

"Not at this time, Commander."

She nodded. Let him go. Her expression didn't change, but her eyes tracked him down the corridor with the attention of a woman who had recently made the biggest decision of her life and was very, very attuned to signs that the people she'd thrown her lot in with didn't trust her.

---

Cross made the decision to bring in Arun at 1400.

She found him in the workspace she'd assigned—a converted maintenance closet on Level Two, equipped with a terminal and access to the station's communications archive. Arun was reviewing fleet communication logs, building the assessment Cross had requested. He'd been working for six hours. The datapad beside him showed handwritten notes in a small, precise script.

"Corporal." Cross entered. Closed the door. "There is a situation I need to discuss with you."

Arun looked up. Read her face. His own expression shifted—the quick recalibration of a man who was trained to detect when a conversation was about to become something more than a conversation.

"You've found something," he said.

"Aria-7 intercepted a coded transmission from Vice Admiral Kaine. Directed at this station. MI-level cipher."

Cross watched his reaction. Not the words—the body. The hands. The eyes. The micro-expressions that MI training taught you to read and also taught you to control. If Arun was the spy, this was the moment. The moment he learned that his handler's communication had been intercepted. The response would tell Cross what she needed to know.

Arun's hands went flat on the desk. Palms down. The gesture of a man stabilizing himself, creating a solid base. His eyes narrowed—not flinching, narrowing. Focus. The pupils contracting as attention sharpened.

"When?" he asked.

"Six hours ago. Aria-7 is working on decryption."

"The cipher type?"

"MI directorate. Non-standard. Aria-7 estimates eight to twelve more hours for decryption."

Arun's jaw worked. Once. The motion of a man chewing on something that tasted wrong.

"There's an agent on the station," he said. Not a question.

"That is the working assumption."

"Not me."

"I have not concluded one way or another."

Arun looked at her. Direct. The eyes of a man who understood that he was under suspicion and was deciding whether to be offended or professional about it. He chose professional.

"If I were the agent," he said, "bringing me into this conversation would be a mistake. You'd be telling me that my communication was intercepted, giving me time to destroy evidence or activate contingency protocols."

"Yes."

"So either you've already concluded I'm not the agent, or you're using this conversation as a test to observe my reaction and make that determination."

Cross said nothing.

Arun leaned back in his chair. "MI directorate cipher means the agent has access to intelligence-grade encryption. That's not standard marine equipment. It's not standard Navy equipment. It's specialist kit—issued specifically to embedded intelligence assets on classified assignments."

"I am aware of what MI directorate cipher implies."

"Then you're also aware that the agent isn't one of the regular marines. The grunts don't carry MI gear. The agent is either someone who was specifically embedded in the boarding force for this mission—unlikely, given the timeline—or someone who was already on this station before the battle."

Cross processed that. Before the battle. That narrowed the field. The station's original crew of twelve had been here for weeks. The refugees had arrived after the battle. Drayden's crew had defected during the battle.

"The refugees arrived after the transmission window," Cross said. "Kaine's fleet withdrew before the transport docked. If the agent was on the transport, Kaine would not have known to direct a transmission at the station."

"Unless the agent made contact through a different channel before Kaine sent the coded message." Arun paused. "But you're right—the timing suggests the agent was here first. Someone who was on the station when the fleet arrived. Someone who has been reporting to Kaine throughout the engagement."

The station's original crew. Twelve people who had been living on the station for weeks before Kira's arrival. Running the basic systems. Maintaining the infrastructure.

"I will need access to the original crew's personnel files," Arun said. "Backgrounds. Service histories. Anything you have."

Cross studied him for three more seconds. His body language had been consistent throughout—the controlled focus of an intelligence professional engaging with a problem, not the carefully maintained calm of a person hiding something. It wasn't proof. Body language never was. But Cross had been reading people for thirty years, and her read on Arun was that the man was genuinely invested in finding the agent, not in protecting one.

"You will have access," she said. "Report directly to me. No one else."

"Understood."

Cross left the maintenance closet. In the corridor, she permitted herself the luxury of a single uncertain breath. If she was wrong about Arun—if the man was the agent and she'd just handed him the keys to the investigation—then the damage would be catastrophic.

She wasn't wrong. She was almost certain she wasn't wrong.

Almost was the word that kept admirals awake at night.

Zeph pressed her face against the inspection window and watched the *Requiem* grow.

The port shield generator coil was forty percent rebuilt. The void-enhanced tissue—that was what she was calling it now, tissue, because it looked more biological than mechanical—had wrapped around the burned-out core and was constructing a replacement from the inside. The new growth was different from the original coil. Not a copy. An improvement. The tissue was denser, the electromagnetic pathways more tightly wound, the structure incorporating elements that Zeph had never seen in any shield generator design.

"You're not just replacing it," she whispered. "You're making it better."

The ship's haptic feedback pulsed. Affirmative. Or agreement. Or just the steady rhythm of a vessel engaged in self-repair.

Zeph switched to the broader diagnostic view and froze.

The bio-growth wasn't limited to the *Requiem*.

Through the docking interface—the shared connection between the ship's modified systems and the station's biological network—data was flowing in both directions. The *Requiem's* damage reports, its system specifications, its engineering parameters were all being transmitted into the warship's network. And the warship was responding. Not just sending energy for repairs. Learning.

"Aria-7." Zeph's voice was tight. The register she used when her brain was moving faster than her mouth. "Are you seeing this? The data flow through the docking interface?"

"I am monitoring. The warship's biological network is receiving telemetry data from the *Stardust Requiem's* damaged systems. The data includes shield generator specifications, hull stress tolerances, and drive efficiency parameters."

"It's studying us. It's learning from our damage—figuring out where we're weak and how to make those systems stronger."

"That interpretation is consistent with the data flow patterns. The warship appears to be incorporating the *Requiem's* engineering data into its own system architecture."

Zeph pulled up the station's internal diagnostic feed—the warship's own biological network, mapped in amber on the schematic. And there it was. Changes. Small. Subtle. In the conduits nearest the docking bay, the warship's organic systems had begun to incorporate new pathways. Shield harmonics that matched the *Requiem's* modified generators. Power routing patterns that reflected the destroyer's drive configuration.

The warship was adapting. Not just repairing the *Requiem*—learning from it. A creature that had been dormant for thousands of years was studying a modern ship's design and integrating what it learned into its own systems.

Mutual evolution. The warship made the *Requiem* stronger. The *Requiem* made the warship smarter.

"That's—" Zeph's hands hovered over the console. "That's prime code, girl. That's really, really prime code."

She started documenting. Voss would want to see this. Cross would want to know the tactical implications. Kira would want to understand what it meant for the warship's combat capabilities.

But right now, Zeph just watched. The amber and green networks, intertwined. Two ships learning from each other. Growing together.

"Yeah?" she said to the *Requiem*. Quiet. Just for them. "You like having a big sister?"

The haptic feedback pulsed.

Lena came to the med bay at 1600 for her resonance check.

Voss ran the scanner while Lena sat on the examination table, her legs dangling, her hands gripping the table's edge with the white-knuckled intensity of someone holding onto something physical because the non-physical things were too uncertain. The resonance signal was steady. Low. Unchanged from the morning reading.

"Stable," Voss announced. "No increase. No decrease. The resonance is maintaining at its current level."

"So it's not going away," Lena said.

"Not at this time. But stability is better than escalation, dear. If the signal were strengthening, we would have cause for concern." Voss set the scanner on the counter. "Any changes in perception? Stronger sensations? Intrusive thoughts?"

"No. It's just—there. Like a sound I can't turn off."

Voss nodded. Made a note on Lena's file. Stepped out to update her records, leaving Lena on the examination table and Kira on the cot three meters away.

Kira watched the girl for a moment. Eighteen. Skinny. Dark hair that needed washing. The look of someone who had been through too much in too short a time and was processing it by gripping furniture.

"How loud is it?" Kira asked.

Lena startled. She'd been staring at the floor. "What?"

"The warship. You said it's like a sound you can't turn off. How loud?"

Lena looked at Kira. The med bay was quiet—just the two of them, the hum of medical equipment, the warship's ambient pulse in the walls. Two people who shared something that nobody else on the station could fully understand.

"Quiet," Lena said. "Like... you know when you're in a room and there's a machine running somewhere else in the building, and you can barely hear it, but once you notice it you can't stop noticing it?"

"Yeah."

"Like that. Except the machine is alive and it's the size of a space station and sometimes I think it knows I'm listening."

Kira sat up straighter on the cot. The headache protested. She ignored it.

"It does know," she said. "The warship is aware of you. You spent two hours connected to it. That's longer than most of my sessions. The creature—it imprints. It remembers the minds that connect to it."

Lena's grip on the table edge tightened. "Can it—does it try to—"

"It doesn't control you. I know it feels like it might. When I first connected, I spent the first twenty minutes convinced that the creature was going to take over my brain and turn me into a puppet." Kira's mouth twitched. Dark humor. The default. "Turns out it's more interested in shield harmonics than mind control. The warship is old, Lena. Very old. It's been dormant for thousands of years. It's not a predator. It's more like—" She paused. "Have you ever seen those old videos of whales? The ocean ones, from original Earth?"

Lena shook her head.

"Big creatures. Huge. They'd swim next to ships and the sailors would be terrified because anything that big should be dangerous. But the whales were just—curious. They'd come close and look at the sailors and then they'd swim away. Not because the sailors weren't interesting. Because the whale had other things to do. Vast, old things. The warship is like that. Curious about you. Connected to you. But not trying to own you."

Lena's fingers relaxed on the table edge. One degree. Two.

"How do you deal with it?" she asked. "The connection. Knowing it's there."

"Sometimes I don't." Kira gestured at the med bay. "I'm in this cot because I tried to reach for the warship when I shouldn't have. I pushed too hard and my brain punished me for it. The connection—it's not just a gift. It's a hunger. It wants to be used. And if you're not careful, you start using it before you're ready."

"Does it ever... talk to you? Like words?"

"No. Not words. More like—direction. A pull. When the warship wants me to know something, I feel it as an orientation. Like a compass needle turning. Not language. Intent."

Lena sat with that. The examination table. The med bay. Two people connected to an ancient intelligence, talking about it the way soldiers talked about incoming fire—honestly, without glamour, with the practical attention to detail that came from living with something dangerous.

"Thank you," Lena said. Quiet.

"For what?"

"For sitting on the floor. In the Throne room. During the battle."

Kira looked at her. The girl on the table. Eighteen. Holding a connection to an alien creature that she never asked for and couldn't give back.

"Any time."

Aria-7 cracked the cipher at 2200. Eight hours early.

"The decryption is complete." The AI's voice cut into the command deck where Cross was reviewing convoy logistics and into the med bay where Kira was trying to sleep. Both women snapped to attention.

"Report," Cross said.

"The transmission from Vice Admiral Kaine consisted of a single coded message. Eleven seconds of compressed data. The content, once decrypted, is four words."

A pause. The AI's processing cycles running something that wasn't computation—something closer to the hesitation of a mind deciding how to deliver information that changed the shape of everything.

"The message reads: 'Is Vance operational? Confirm.'"

Kira sat up in the cot. The headache flared. She didn't care.

Four words. Not a set of orders. Not a strategic directive. Not a plan of action. A question. Kaine wanted to know if Kira could fight. If her neural pathways were functional. If the woman who had turned his flagship into a spinning top and driven his fleet into retreat was capable of doing it again.

"He's making his plan contingent on my condition," Kira said. The words came out cold. The tactical register. "If I'm operational, he prepares for a fight against the warship at full capability. If I'm not—"

"If you are not," Cross finished, "he attacks before you recover. The timing of his assault depends on the answer to that question."

Someone on this station knew about Kira's neural damage. Someone knew about the seizure, the inflammation, the setback, the recovery timeline. And someone was prepared to transmit that information to Vice Admiral Kaine so he could decide when to come back and kill them all.

The message wasn't orders to a spy. It was a question to someone who had already been reporting. Someone who had been watching Kira. Watching Voss's treatments. Watching the med bay visits and the recovery updates and the conversations about neural pathways and inflammation timelines.

Someone close.

Kira looked at the med bay walls. The amber light. The warship's steady pulse. The station that she'd been defending from enemies outside while an enemy inside counted her heartbeats and reported them to the fleet.

"Who knows about my neural damage?" Kira asked.

Cross was already ahead of her. "The crew. Voss, obviously. Jax and Malik. Zeph. Aria-7. Myself." She paused. "Lena was in the Throne room during the injection and the session. Drayden was briefed on your general condition—I disclosed that you were temporarily unable to interface with the warship."

"The med bay isn't private. Anyone walking past could see me in here. The refugee processing area is one level away. Station crew move through these corridors."

"Yes."

The list of people who could have observed Kira's condition was essentially the entire station. But the list of people who knew the details—the neural pathways, the inflammation, the specific recovery timeline—was shorter. Much shorter.

"Narrow it," Kira said. "Aria-7, cross-reference the transmission timing with activity logs. Who was near a communications device at the moment Kaine's message was received? Who could have sent a prior report about my condition?"

"I will begin analysis immediately."

"And Cross." Kira's eyes found the admiral through the comm's video feed. "The convoy raid. We proceed as planned. But we feed the spy false information."

Cross's mouth curved. A fraction of a degree. The expression of a woman who had just been given permission to do what she did best.

"What would you like the spy to believe about your condition, Commander?"

Kira lay back on the cot. The headache pounded. Her left hand twitched once—the neural pathways misfiring, a reminder that the damage was real and the recovery was incomplete and the enemy knew exactly how broken she was.

"Tell them I'm getting worse," Kira said.
