At 8:59, Zara took her phone out of her bag, opened the voice recorder, and pressed the red button.
She had checked the law on the way to work, standing on the overground with her coat buttoned to the throat. A person could record a conversation they were part of. What they did with the recording afterwards was a separate question. She would answer that question later.
She slid the phone into her jacket pocket, screen facing her ribs, and knocked.
"Come in."
Mr. Halcott's office was the largest room on the fourth floor. Two tall Georgian windows looked down onto Fetter Lane. A framed print of the Thames at Greenwich hung above the fireplace, and she wondered, briefly and coldly, how many times she had walked past it without seeing it.
He was not pacing. That was the first thing she noticed. For six months she had watched him wear a path in the corridor carpet whenever a matter went badly. This morning he was sitting perfectly still behind his desk, hands folded, with a single pen lying in front of him.
The ink in its barrel was red.
"Please close the door," he said.
She closed it. She did not sit.
"You recognised the handwriting," he said.
"Yes."
"I thought you might. You notice the things other people stop seeing." He looked at her the way he looked at a contract he had already decided to sign. "That's the whole of it, really. That's why you were chosen."
"By whom?"
"By people like me." He unfolded his hands. "For twenty-two years, Zara, a small number of senior practitioners in this city have bought copies of files that were never meant to leave the rooms they were made in. Police files. Disclosure bundles. Coroners' papers. We never used them in court. We used them to know. Which cases were being buried. Which investigations had been told to go slowly. Which defendants had friends in the right places."
"You bought stolen evidence."
"We bought sight," he said. "The system is slow and it can be bent. We made sure some of us could see where it was bending."
"And Diane Ashworth?"
For the first time, something moved in his face.
"The shop was never meant to sell to people like her," he said. "For twenty years it didn't. Our source was careful, and we were the only customers. Then, eighteen months ago, the source started selling to anyone who could pay. Diane Ashworth bought the date an inquest opened and the hour a police statement began. A man called Jordan Fitch bought the right to ring you on the evening you posted your timeline." He paused. "I don't know who Jordan Fitch is. That's what frightens me."
"So you found someone to stop the source."
"We found someone the source couldn't buy." He said it simply, as if it were obvious. "You are the only person in this entire affair who has never paid for a single page. You're not in the catalogue. You're the one thing in it that isn't for sale."
Zara felt the phone against her ribs. Small. Steady. Recording.
"Amara Solis," she said.
"A colleague. She made the call because I couldn't. You'd have known my voice."
"You put me on the Ashworth case so I'd find the leak."
"I put you on the Ashworth case because two women were about to carry a murder they did not commit, and you were the best reader I had ever employed." He held her gaze. "Finding the leak was the second reason. I won't pretend it was the first. I also won't pretend it wasn't there."
"And Mr. Adeyemi's code?"
A silence. Longer.
"The source watches," he said at last. "If copies had come off my code, the source would have known I had broken the arrangement. Raymond has been in this building for nine years. Nobody would ever think him capable of anything."
"So you let him carry it."
"I would never have let it reach him."
"You'd already let it reach him," Zara said. "He found it three weeks ago. He's been coming in at half six to catch a thief who was his own partner."
Mr. Halcott looked down at the red pen.
"The initials," she said. "S.O. On every page. You wanted me to stop trusting Detective Ola."
"I wanted you not to take this to the police," he said quietly, "until you understood that the police were where it started. Ola is honest, as far as I know. But everything you gave him would have gone into a building where somebody sells what comes in."
It was, she thought, the most honest thing he had said. It did not make the rest of it any less of what it was.
"What do you want from me?" she said.
He opened a drawer and took out a single sheet of paper. He laid it on the desk, facing her.
It was a training contract. Two years. Halcott & Boye. Her name already typed in the first line. A salary figure that would cover her mother's scans, Kofi's school trips, the travel card and the weekly shop, with something left over at the end of each month for the first time in her life.
"Find the source," he said. "Quietly. The way you found the gun and the trust. And when you've found it, you bring it to me first, not to the police, and we close the shop ourselves. No trials. No catalogue read out in open court. No list of names."
"Your name," Zara said.
"Among others."
She looked at the contract. She let herself look at it properly, the way she looked at everything, so that later she could never tell herself she had not understood what she was refusing.
Then she thought about Elena Marsh with a mug between her hands. Forty thousand pounds. Half before, half after. About Dr. Nadia, whose excellence had been part of the design.
Someone chose you very carefully. And knew exactly what to offer.
"No," she said.
Mr. Halcott did not look surprised. He looked, if anything, tired.
"You understand what that means for your position here."
"I've read my contract," Zara said. "The one I already have."
She took the phone out of her pocket and turned the screen toward him. The red dot. The seconds still counting.
He looked at it for a long moment.
"That's lawful," he said. "What you do with it next may not be kind to you."
"It wasn't kind to Lena either," she said. "Or to Elena. Or to anyone else in your catalogue."
She stopped the recording. She saved it twice. Then she walked out, closed the door behind her, and went down the stairs without looking back.
Mr. Adeyemi looked up as she passed his desk. He saw her face and did not ask anything. He simply picked up his phone, and she understood that he was ready to be a witness to whatever came next.
On the stairs she stopped, between the third floor and the second, where the burgundy carpet was most worn. She sent the recording to Marcus with no message attached. Then to her personal email. Then she wrote the time in her notebook, 9:23 a.m., and beneath it the only thing she was sure of.
He told the truth about everything except himself.
She thought about the scan on the nineteenth. The deposit she had been setting aside from a salary that, as of this morning, she no longer had. She thought about telling her mother. She put the thought away carefully, the way you put away something you would have to pick up again later, and kept walking.
She got as far as Fetter Lane.
The street was busy with the mid-morning crowd. Couriers. Clerks with trolleys of bundles. The coffee shop queue out of the door. She stood on the pavement with the recording in her hand and her whole income gone, and for a moment she let herself just breathe.
Someone fell into step beside her.
A young man. Early thirties. A good coat, a neutral face, the kind of polished flatness in his voice that had been trained into him.
She had heard that voice once before. On a pavement, in the cold, fifteen minutes after she posted eleven pages.
"Ms. Ademi," he said pleasantly. "We spoke on the phone a while ago. You can keep calling me Jordan Fitch, if you like. It's as good a name as any."
He did not stop walking. He did not look at her.
"My employer would like a word," he said. "About that recording in your hand."
