The café was on Pine Street.
Small. The kind of place that had been there long enough to stop caring about being found and had become beloved precisely because of it. Six tables. A counter with stools. Coffee that came in plain mugs without any ceremony about it.
Dana Tsui was already there.
She was at the table in the back corner, not because it was the most defensible position though it was but because it was the table farthest from the window and she had chosen it without appearing to choose it, the way people with her particular history made decisions. Naturally. Automatically. The habit of four years of careful living.
She was smaller than the photograph suggested. Not fragile. Compact. The watchful face was the same but in person it had a quality the photograph had not captured a kind of constant low-level reception, as if she was always processing slightly more than the surface of the moment contained.
She looked up when Rof walked in.
She looked at him the way Silas looked at people, but differently. Silas read pattern and prediction. This was something else. She looked at him the way certain animals looked at something they had detected before it came into range. Recognition without prior meeting.
He sat across from her.
She said nothing for a moment. She was holding her coffee mug with both hands and she looked at him with that quality of reception and he let her look.
"S8," she said finally.
"Rof," he said.
Something moved at the corner of her mouth. "Rof," she said. She tried it out like a word in a language she was learning. "I watched the Tank fight six times. The Silas fight eleven." She looked at her mug. "The Okon fight I've only watched twice. The third round I can only get through once before I have to stop."
"Why," he said.
She looked up at him.
"Because I felt it happen in real time," she said. "From Seattle. I was asleep. Three forty-seven in the morning. I woke up and I felt it like a shift in pressure. Like the moment before lightning." She looked at her hands. "I have felt the others activate before. Distant. Muffled. Like hearing music through a wall." She held his gaze. "Yours was not through a wall. It was in the room."
Rof looked at her.
"What does your ability do," he said.
She was quiet for a moment. Not deciding whether to answer. Deciding how.
"I perceive frequency," she said. "Not sound. Not light. The underlying frequency of living things. Every person has one. Every activated subject has one that is distinct from ordinary human frequency." She paused. "When the speed activated in round three you did not just change frequency. You changed the frequency of the room." She looked at him steadily. "Seven people in that warehouse experienced a physiological response they could not explain. Elevated heart rate. Sudden clarity. Two of them cried and didn't know why."
Rof thought about the crowd making the sound that was not a normal crowd sound.
"I know," he said.
"What you don't know," she said, "is that the frequency you produced in that room matched something I have only encountered in one other place." She held his gaze. "The program notes. E. Voss's original theoretical framework. Before he built the experiment. Before the twelve subjects. Before any of it." She paused. "He described a theoretical frequency. A baseline. The frequency he believed the experiment was trying to access." She held his gaze. "He called it the Ground Tone. He said it was the frequency beneath all other frequencies. The one everything else was built on." She paused. "He said if any subject ever produced it the experiment would have exceeded every projected parameter."
The café was very quiet around them.
"You're telling me I produced it," Rof said.
"I'm telling you that what you produced in round three was closer to E. Voss's theoretical Ground Tone than anything I have measured in four years of tracking the subjects." She looked at her coffee. "I'm not saying you've reached it. I'm saying you're approaching it from a direction nobody predicted."
Rof sat with that.
He did not reach for the implications of it. He let it be information. The same way he let everything be information first before it became anything else.
"Why did you come here," he said.
She looked at him.
"Because Rael is going to try to use you as the centerpiece of Synthesis," she said. "And I have spent four years running from this and I am tired of running." She set her mug down. "And because whatever you are approaching, whatever the Ground Tone actually is when a person reaches it fully " she paused "I do not believe Rael should be the one in the room when it happens."
Rof looked at her.
"You're not here to hide," he said.
"No," she said. "Not anymore."
Outside on Pine Street the afternoon moved past the window in its ordinary way. People with places to be. A dog pulling its owner toward something interesting on the other side of the street. A bus stopping and opening its doors and taking people in and moving on.
"Okafor," Rof said.
"I know about Okafor," she said. "S11. He's been building toward something for years. I've known about his network for eight months." She looked at Rof. "I did not join it because I did not trust the shape of it." She paused. "I trust you."
"You don't know me," Rof said.
"I felt your frequency from two thousand miles away at three forty-seven in the morning," she said. "I know you better than most people I have met in a room."
Rof looked at her for a long moment.
She looked back.
The watchful face was not guarded. It was honest. The particular honesty of someone who had been alone with a truth for a long time and had decided today was the day to set it on a table in front of another person.
"There's a meeting," Rof said. "Okafor. Okon. Silas. Vera." He held her gaze. "You should be there."
She nodded once.
"One condition," she said.
"What."
"The meeting stays off Rael's grid. Completely." She held his gaze. "I have been careful for four years. I have not made a single mistake. I am not going to start now."
"Vera runs our security," Rof said. "She hasn't made a mistake either."
Dana Tsui looked at him.
She picked up her coffee.
She drank from it.
"Okay," she said.
They sat for another twenty minutes. She told him things about the program he had not known. Not from the documents. From direct experience. She had been seven when the visits happened. She remembered more than most of the others because her ability had been active at low levels even then, absorbing things the other children's minds had let pass.
She remembered E. Voss.
Not his face clearly. But his voice. The particular careful way he spoke to the children, not talking down to them, explaining things in plain language, as if he genuinely believed they deserved to understand what was happening. She said it was the thing that had confused her most in the years afterward. He had not seemed cruel. He had seemed convinced. As if what he was doing was the most important thing any person had ever done and he was sorry it had to involve children but the alternative was not doing it at all.
"He believed in it," she said. "Whatever the Ground Tone was supposed to be, whatever Synthesis was supposed to produce he believed it was worth it."
"People who believe in things are the most dangerous kind," Rof said.
She looked at him.
"Yes," she said. "They are."
He left the café at three forty.
He walked back toward the trailer through the afternoon city. The sun was doing its late afternoon thing, the shadows long and the light amber and Philadelphia wearing its particular end-of-day quality.
He thought about the Ground Tone.
He thought about E. Voss in a room with seven children and a conviction that what he was doing mattered enough to do it.
He thought about his father's photograph. The smiling boy in the chair in the white room. Gap-toothed and unaware.
He stopped on the corner of Broad and Federal and stood for a moment.
He put his hand on the cross through his shirt.
He held it.
He did not pray in words. Just held it. The way his father sat with the Bible open in his lap without reading it. The act of proximity to something larger than the immediate problem.
He kept walking.
Nine days.
