What Callum Captured

The night of the final recording session was Callum's idea.

He'd proposed it two days after Della was found, in the meeting room at ML Detectives, presenting it the way he presented everything — methodically, with his reasoning laid out in order, the logic of it visible from beginning to end. The acoustic data from the tree line session had given them a precise source location. The analysis of the almost-words from the previous night session had given them a frequency profile detailed enough that a final recording from inside the tree line, positioned correctly, would either confirm or significantly advance everything Priya had been building toward. One more session. Properly positioned. With the full equipment setup rather than the reduced configuration they'd used when caution had kept them at the boundary.

Priya had agreed immediately. Nina had agreed after a moment's consideration. Morganta had said she wanted to think about it and then said yes the following morning.

They planned it for a Thursday night. Late — after midnight, which was when the signal was strongest, which was when the almost-words in the previous recording had emerged from underneath the frequency. Full equipment setup. Morganta and Lexus inside the tree line with Priya while Callum managed data from the car, Nina beside him. Ro in the car.

Ro didn't argue about being in the car. She'd been different since their conversation outside the hospital car park, since Morganta had said I'll stay in contact with her and Ro had said someone should have done that for Marcus's friend. Something had settled in Ro since then, not resolved — nothing had resolved for Ro, Morganta understood that, it wasn't the kind of thing that resolved — but settled, like something had been acknowledged and the acknowledgment had given her somewhere to put her feet. She'd been more present in the group work, less alone in the room even when she was sitting apart from everyone.

She got in the car Thursday night without being asked and pulled the door closed.

They went in at twelve thirty.

The forest at night was a completely different thing from the forest in the morning, and Morganta had known this intellectually from the previous session and from every account she'd read, but the reality of standing inside the tree line at twelve thirty in the morning with torches and equipment cases was still something that required a moment of adjustment. The darkness between the trunks was absolute in a way that daylight hours didn't prepare you for. The sounds were different too — fewer of them, the small daytime wildlife sounds gone, replaced by a deeper quiet that had more presence to it, more weight. The frequency was immediately noticeable. Not gradually building the way it had in the daytime session but present from the first step inside the tree line, full and immediate, like entering a room where something had been happening before you arrived.

Priya moved quickly, efficiently, her torch mounted on her head leaving her hands free for the equipment. Morganta watched the darkness ahead and to the sides, a directional sweep she repeated without stopping, methodical, keeping her breathing steady and her attention outward. Lexus was to her left, slightly behind, doing the same thing in a different direction. They'd talked about this beforehand, about what they were watching for and how they'd signal each other, and the conversation having happened meant that now they could just do it without discussion taking up attention they needed elsewhere.

The frequency built as Priya set up. That was the first thing that was different from the daytime session — it built. It wasn't static. It responded to their being there in a way that couldn't be explained by their physical presence affecting the acoustic environment, couldn't be attributed to anything they were doing. It simply increased, gradually and steadily, as though registering them.

Morganta felt it in her chest, the low vibration of it, and kept her face still and her breathing even.

Priya had the setup complete in twelve minutes, which was faster than any previous session. She settled into position, headphones on, equipment running, and gave Morganta a thumbs up that meant she was recording and they should hold position.

They held position.

The first forty minutes were the frequency and nothing else. Priya crouched over her equipment in the torchlight, monitoring levels and making small adjustments, completely absorbed. Morganta and Lexus maintained their watching positions, trading glances occasionally, the steady communicative glances of two people who knew each other well enough that a look contained several sentences.

At approximately one fifteen the frequency changed.

Not in volume. Not in the basic character of it. But in the way it was structured — something altered in the layering, the way the components of it sat on top of each other, and the change was subtle enough that Morganta wasn't certain she'd noticed it for a moment, was uncertain whether she was projecting pattern onto randomness, and then the change continued and became impossible to attribute to imagination. The layers were rearranging themselves. Slowly, deliberately, moving against each other in a way that had a quality of—

She looked at Priya. Priya had gone very still, which meant she was hearing it too.

The almost-words from the previous recording had sat just below resolution, just out of reach. What was happening now was different. The rearranging of the layers had created something in the sound that was closer to the surface. Not language exactly, still not language she could parse, but the sense of language, the shape of intended communication, was stronger than anything in the previous recordings.

Morganta stood in the dark forest and listened with her whole body and tried to receive whatever was being produced without reaching too hard toward it, the same way you sometimes hear something better when you stop trying so hard to hear it.

It lasted approximately twenty minutes, this period of altered layering, this closer approach to resolution. Then the layers shifted back toward their baseline configuration and the almost-words receded again and the frequency returned to its usual steady omnipresent pulse.

Priya took her headphones off. In the torchlight her expression was careful and precise, the expression of someone who had just received something significant and was holding it steadily while she decided what it was.

They packed up and went back to the road.

In the car, nobody spoke immediately.

Callum took Priya's equipment and began the data transfer, connecting her recording unit to his laptop, running the file. Nina sat beside him looking at the preliminary display without speaking. Ro was in the back seat. She hadn't asked anything yet. She was watching Morganta through the car window from the back seat with that quiet steady gaze.

Morganta stood outside the car at the verge, looking at the tree line. Lexus stood beside her. The cold night air was completely still. The road in both directions was empty, no headlights, no sound of distant traffic, just the night and the trees and the frequency that she could still feel faintly even out here, even at the road's edge.

Callum knocked on the window from inside. She went around to the driver's door and he opened it and turned the laptop toward her. "Look at this," he said.

She looked at the spectrograph on the screen. The recording from the previous session, with the almost-words, had shown a dense layering that Priya had described as acoustic chaos with underlying structure. What Callum was showing her now was different. The new recording, from tonight, showed the same dense layering — and then, for a twenty minute section corresponding to the period of altered layering she'd felt inside the tree line, the display changed. The layers didn't resolve into clarity exactly. But they organised. They arranged themselves into a pattern that was more structured than anything in the previous data, more intentional-looking, more—

"Syntactic," Priya said from the back seat, leaning forward. "That's the word I keep coming back to. The structure isn't random and it isn't just acoustic patterns that happen to resemble structure. It has the organisation of syntax. The way words build into phrases. The way communication is built."

"But not a language we can identify," Callum said.

"No," Priya said. "Not any language in any database I can access. But the structure of language. The skeleton of it."

Morganta looked at the display. At the twenty minute section of organised layering. At the point where it built toward something and then receded. She thought about standing in the trees and receiving it without understanding it. She thought about Della saying it showed me things and not having words for what.

"Play it," she said. "Slowed down. The twenty minute section."

Callum looked at Priya. Priya nodded. He found the section and reduced the playback speed and hit play.

The sound that came out of the laptop speakers was lower than the original, stretched, the layering pulled apart slightly by the reduced speed so the components were slightly more separable. In the car, in the dark, at the edge of West Kingsport Road in the early hours of a Thursday morning, they all listened.

It was closer than anything before. That was the first thing. The resolution was closer, the sense of something trying to communicate something pushing further toward the surface. Morganta sat with it and listened and tried to let go of the effort of understanding.

Then something happened that none of them had expected.

Ro, in the back seat, said very quietly: "Marcus."

Everyone looked at her.

She was looking at the laptop speaker. Her face had gone completely still, the way faces go still when something has removed the ordinary surface movement of expression and left just the underneath of a person. "That's his voice," she said. "In there. One of the layers. That's Marcus."

Nobody said anything for a moment.

"Ro—" Nina started.

"I know what my brother's voice sounds like," Ro said. Completely steady. Not breaking, not unravelling. Just certain, the certainty of someone who knew something with a knowledge that went below the level where argument could reach it. "One of the layers in there is Marcus."

The recording played on from the speakers. The stretched, slowed, almost-language of it filling the car.

Callum slowly reached out and stopped it.

The silence after was complete.

Morganta looked at the spectrograph on the screen. At the organised layering of the twenty minute section. At the syntax of it, the structure that Priya had described, the skeleton of communication. She thought about what Priya had said months ago in the kitchen, when they'd first heard the recording with the almost-words: that's why it gets the voices right, that's where it's getting them from.

She thought about the Dawson family. About five names on a memorial plaque outside a library. About Enzo saying that's John's shirt in the voice of a man who already knew something the others were still understanding.

She thought about the voices of the missing woven into the frequency like threads.

She looked at Ro.

Ro was looking at the stopped spectrograph on the screen. She wasn't crying. She wasn't doing anything that could be described as falling apart. She was sitting in the back seat of a car on a dark road at two in the morning with the complete stillness of someone who had just had something confirmed that they'd been hoping for and dreading in equal measure for six years, and she was holding it.

"Ro," Morganta said. She kept her voice level and quiet. "Are you alright?"

Ro looked at her. Something in her expression that was too large and too honest for the confines of a car in the dark. "No," she said. "But I'm here." She looked at the screen. "He's in there."

"Something that was part of him is in there," Morganta said carefully. "That's what we believe. What that means exactly—"

"I know what it means," Ro said. "Or I know enough." She looked at the tree line through the car window. "He's not coming back. Is he."

It wasn't quite a question. The inflection was there but the need for an answer wasn't. She already knew. She had probably known for six years and been building a structure of research and purpose around the knowing because building something is how you function when you know something you can't accept yet.

Morganta looked at her. She thought about what honesty looked like here, what kindness looked like, whether they were the same thing or different things.

"I don't think so," she said. "I'm sorry."

Ro nodded. Once, carefully. She looked at the tree line for a long moment. Then she looked back at the laptop screen. "Then we make it stop," she said. "Whatever it is, whatever it does, we make it stop doing it." She looked at Morganta. "Tell me what you need me to do."

They stayed in the car until almost three.

Nobody drove anywhere. Nobody suggested going back to the house or the office. They just stayed there at the verge with the engine off and the laptop open and the recording file sitting on the screen, and they talked.

Callum went through the technical findings first, because Callum processed things through structure and right now structure was useful for all of them. The syntax of the twenty minute section. The way it organised differently from everything before it. His preliminary analysis suggested that the altered layering they'd captured tonight was not random and not a function of atmospheric conditions or equipment behaviour — the changes in the signal were consistent with something that had adjusted its own output intentionally. Something that had become more organised in its production of the sound during the period they were present inside the tree line.

"It knew we were there," Priya said. "And it changed what it was doing in response."

"It's been knowing we're there since the first day," Morganta said. "Since the first morning session on the road. It's been aware of us the whole time."

"But tonight was different," Lexus said. "Tonight it produced something structured. Something with the shape of communication. Why tonight? Why not before?"

Nina looked at the screen. "Because tonight we were close enough," she said. "Priya's positioning inside the tree line, the full equipment setup, the recording sensitivity. We were close enough to the source that whatever threshold governs whether it attempts communication—" she paused "—we crossed it."

"It was trying to talk to us," Callum said.

Nobody disagreed with this even though it was a sentence that would have sounded wrong in any other context.

Morganta looked at the screen. At the twenty minute section. At what Priya had called the skeleton of communication. She thought about what it had been trying to say, whether there was a way to know, whether there was ever going to be a way to know. She thought about Della saying it showed me things and not having words. She thought about whether the things it showed were another form of the same communication, whether being inside it was the only way to understand what it was saying.

She thought about going in.

She thought about what Nina had told her. The exempted person. Going back in. Coming back out quieter.

She looked at Lexus across the centre console. He was looking at the spectrograph on the laptop, his profile in the dark of the car, the steady quality of him that had been steady since the first day she'd worked with him and had not become less so in two years of working alongside him and one year of being married to him.

She would tell him tonight. What she'd been thinking about. What she was considering. She wasn't going to do anything without telling him, wasn't going to make a decision that large without putting it in front of him first, because that was what their partnership meant and because she was not capable of being the kind of person who did something like that alone in secret and still respected herself.

But she wasn't going to say it in the car with everyone present. She was going to say it at home, tonight, when it was just the two of them, the same way they'd talked about everything else.

"Callum," she said. "The twenty minute section. Can you isolate the section where Ro heard Marcus?"

Callum looked at her. Then at Ro. "Is that—" he started.

"Yes," Ro said. "Find it."

He worked quietly on the laptop, isolating the section, running it through analysis. After a while he identified a frequency layer in the lower register of the recording that had a different character from the surrounding layers — a different resonance, a different quality that his analysis flagged as potentially vocal in origin. He isolated it. Extracted it. Reduced it further.

He played it.

Seven seconds of something that was barely there. Low, stretched by the reduced playback speed, barely distinguishable from the ambient noise of the recording. But with a quality to it that was different from the frequency. A human quality. The residue of a human voice in something that had absorbed it and held it and woven it into itself.

Ro sat very still in the back seat and listened to seven seconds of something that might have been her brother's voice.

When it stopped she pressed her hand flat over her mouth for a moment and sat that way. Then she took her hand down and looked at the dark road ahead and breathed steadily and said, very quietly: "Thank you."

Nobody said you're welcome. It didn't need a response.

After a while Nina spoke. "We're close," she said. "Whatever is going to happen next, we're close to it. The recording tonight moved us further than anything before. We need to think carefully about next steps."

"Tomorrow," Morganta said. "We talk about next steps tomorrow. Tonight we go home."

Nobody argued. Callum closed the laptop. Priya gathered the equipment cases. They separated into their two cars and drove back through the dark quiet roads of Kingsport, the city asleep around them, everything ordinary and unconcerned and entirely unaware of what had been captured on a recording at the edge of a forest on a road that looked like any road anywhere.

At home, after midnight, Morganta sat at the kitchen table across from Lexus with two cups of tea between them that neither of them was drinking. The flat was quiet. The street outside was quiet. Everything quiet.

She told him what she'd been thinking about.

She told him about the exempted person going back in. About the Norwegian account. About coming back out quieter. About what she'd been sitting with since Nina had told her, turning it over, carrying it. She told him she thought she was the mechanism, the way Nina had put it. The person who could get closest without being taken, because it had looked at her and made a decision, and that decision might be the key to understanding how to make it stop.

Lexus listened to all of it without speaking. He sat across the small kitchen table with his hands around his cup and his eyes on her face and listened.

When she finished he was quiet for a moment.

"You're thinking about going in," he said. Not accusing. Just naming it accurately.

"I'm thinking about it," she said.

He looked at the table. At his cup. At the ordinary kitchen around them, the familiar quiet of their home at this hour. Then he looked at her.

"Not yet," he said. "We're not at that yet. We're not close enough to understanding what it means and I'm not going to let you go somewhere unknown for a reason we don't fully understand yet." He paused. "We're close. Nina said we're close. So we get closer first. We understand it better first." He looked at her steadily. "And then we talk about it again."

Morganta looked at him. At the steadiness of him, the consistency of it, the fact that he hadn't told her she was wrong or frightened her or immediately begun arguing against it. He'd just said not yet with a specificity that meant he'd heard her and was taking it seriously and had a position that wasn't refusal but was boundary.

"Not yet," she agreed.

"But you'll tell me when the thinking changes," he said.

"I'll tell you," she said.

He reached across the table and covered her hand with his. They sat like that for a while in the quiet kitchen, the tea going cold, the city outside doing whatever cities do at this hour which is mostly nothing, and outside somewhere in the direction of Fraser the tree line stood dark and unchanged and full of its layered frequency and its almost-language and the voices of the people it had taken woven into everything like threads you couldn't separate from the cloth.

Morganta looked at the wall and thought about going in and coming back out quieter and what quieter meant and whether she was ready to find out.

Not yet.

But closer than before.
