Faith Njeri remembered the request because the man had asked her to write down a refusal.
She did not tell that to Yanchuan. She told the investigator, who recorded her account and later shared a limited summary with the family. Yanchuan read it on a Friday night while An waited on the call. They had agreed not to open new developments alone when they could help it.
Faith worked at the service compound’s receiving counter. She handled deliveries, passes, and requests for records kept in the maintenance office. On October 30 a visitor had asked for the ticket concerning a temporary cooling arrangement. He gave the name Lin Yansheng. Her colleague entered the name in the book while she searched the request list.
She found the ticket number. She did not find authorization to release a copy.
According to her account, the visitor had not argued. He asked whether she could record that the document existed but could not yet be provided. Faith wrote the reference on a request slip, marked it pending authorization, and told him what she could and could not promise.
He thanked her for making the distinction.
“That’s something he would do,” Yanchuan said.
An did not answer immediately.
It was something Yansheng would do. It was also something any experienced auditor might do when a document was refused. They had promised themselves not to let recognition perform identification.
“Did she know his face?” An asked.
The summary said Faith had identified the man in the equipment photograph as probably the visitor. She also said she had dealt with many people that month and could not be certain from memory alone. The investigator was comparing her account with the original register and request slip.
Yanchuan read that qualification aloud. It seemed to make the silence at the end of the sentence larger.
“She remembers a conversation,” An said. “There’s a request made at the time.”
“Yes.”
“That’s more than we had yesterday.”
He had been about to send his father a message saying Someone saw him on Friday. Instead he deleted the sentence and called Jianming with An.
Their father asked which office, what time, and whether the clerk had met Yansheng before. When Yanchuan explained the limitations, Jianming asked a question neither of them had prepared for.
“Will this woman be safe?”
“I don’t know,” Yanchuan said. “The investigator spoke to her. We haven’t approached her ourselves.”
“Good. Thank her when it is proper.”
Yanchuan thought of the company manager’s fruit basket, the requests made in polished language, and the way help could arrive with a sentence someone expected you to sign. His father was asking after a woman whose full account he had not been permitted to read.
On Monday, Amina called during a break. Someone at the compound had begun saying the missing auditor’s relatives were paying for names. A maintenance worker had been asked whether he could introduce the family to anyone willing to talk privately.
“Was it the man who sent me the gate photograph?” Yanchuan asked.
“We don’t know. It may have nothing to do with him.”
“I never hired him.”
“I know. Rumours don’t check your accounts.”
Amina said workers were asking what Faith had told the police. She could not determine how the account had spread, nor whether anyone had complained to Faith directly. That uncertainty mattered because Yanchuan was already imagining a supervisor standing over the clerk’s desk.
“Can’t we tell people she’s helping a missing person’s family?”
“Then everyone knows she is helping. You would be explaining her decision for her.”
He looked down at his phone. He had wanted to send flowers to the receiving office that morning. The idea, until this moment, had felt kind.
“What can I do?”
“Tell Wanjiru about the rumour. Don’t ask for Faith’s personal number. And if you hear something about her, find out who actually heard it.”
He did both. Wanjiru recorded the concern and asked that any further approach to potential witnesses go through the appropriate case team. She would not promise this could protect Faith from every question at work. The family had no authority to offer employment security, and a public declaration of support could expose the person it praised.
That evening An received a message from Rose Otieno. Daniel’s treatment expenses had been reconciled against the wrong employer account again. Rose wanted help understanding two amounts, not a story about her husband’s role in the missing-person inquiry.
An opened a separate spreadsheet.
Yanchuan was on the video call and watched her label the columns before saying anything.
“Are you going to ask them about the note?” he said.
“No.”
“I only meant—”
“I know what you meant. She asked about a payment.”
He apologized. An worked through the figures with Rose, marking which amount had been paid, which was still described as pending, and where the statements disagreed. At the end Rose said she would take the reconciliation to the person helping with Daniel’s employment case.
When Rose ended the call, An kept the spreadsheet open. Yanchuan offered to help with the figures.
“You were here when she asked,” An said. “What I needed was for you not to turn her accounts into an interview.”
He had thought his apology settled the moment. It had only acknowledged it. He asked whether there were any invoices he could verify without speaking to Rose, and An sent him two.
Later Yanchuan called Amina to ask whether he had misunderstood her warning.
“No,” she said. “You understand it. You just wish helping one family would also let you help your own.”
He could hear dishes being put away at her end. He had no idea who else lived in her home. He had begun, at last, to notice the gap between a name on his case list and the life to which that name belonged.
In the office the following morning Chen returned Yanchuan’s cooling calculation with likely circled in red.
“You meant possible,” Chen said.
Yanchuan looked at the sentence. He had.
He corrected it, then added the assumption the client would need to judge the possibility for itself. Chen read the revision and handed it back without comment.
At night An sent a photograph of their son’s wooden bridge. One support had been removed, but the upper span still stood.
Yanchuan called to ask how the boy had managed it.
“We moved the load,” his nephew said, pleased with himself. “It was too heavy in the middle.”
He listened while the boy explained the new bracing and the test he wanted to run on Saturday.
After the call, the case summary was still open on the screen. A woman had remembered a request and identified a face with care. She had a job, people waiting for her after work, and reasons to measure every word. Yanchuan did not know what those reasons were. He did not need to know them to take them seriously.
The question of his brother’s Friday visit was no longer empty.
He closed the summary before writing to Wanjiru. Whatever Faith had risked by remembering, he would not ask her to risk more to satisfy his impatience.
