Simi's mother, Mrs. Adeyinka, lived in a quiet part of Surulere in a house that smelled of camphor and old paper and the particular warmth of a kitchen that had been cooking since early morning. She was a small woman with close-cut grey hair and the unhurried manner of someone who had decided a long time ago not to be rushed by anything.
She sat them down at her dining table and placed a box between them without ceremony. It was a storage box, the cardboard kind, reinforced with tape and labelled in a handwriting Diane didn't recognise.
"I kept everything," Mrs. Adeyinka said. "My supervisor at the trust told me to keep nothing when I left. That was the first time in fifteen years anyone had ever told me that and it told me everything I needed to know." She opened the box and began setting folders on the table in a neat row. "I took copies of the secondary accounts going back to 1997 when I started. I never looked at them again until last night."
She opened the second folder and slid a single sheet across the table.
It was a payment record. Quarterly disbursements from a Marchetti trust sub-account, going back to 1999. The recipient was listed only as a reference code: OA-7741. Regular, consistent, every quarter without fail. The amounts were not enormous but they were not small either. Over twenty years the total would have been significant.
"OA," Diane said.
"I asked my supervisor once what the code stood for," Mrs. Adeyinka said. "He told me it was a legacy account from the original partnership and that I should process it and not discuss it. So I did." She folded her hands on the table. "What I did not do was stop noticing. The payments continued every quarter. They never missed. Even in years when the trust was in dispute or the accounts were restructured. That account was protected above everything else."
Adrian leaned over the sheet. "Is there a bank reference? A receiving institution?"
"There is." Mrs. Adeyinka turned the sheet over. On the back, in pencil, was a bank code and partial account number. "I wrote it down the last year before I left. I don't know if the account still exists."
Adrian photographed it immediately. He sent it to someone without explaining who and Diane watched him and decided not to ask yet.
"Mrs. Adeyinka," Diane said. "The payments. Did they ever have a name attached. Anywhere in the files."
The older woman was quiet for a moment. She reached back into the box and removed a smaller envelope, the kind used for internal memos, yellowed with age. She placed it on the table but kept her hand on it.
"In 2007 there was a clerical error," she said. "Someone at the originating bank included a beneficiary name on the transfer record instead of the code. It came through on my monthly reconciliation report." She looked at Diane. "I flagged it to my supervisor. He corrected it the same day and the name disappeared from all the records." She paused. "But I had already written it down."
She lifted her hand from the envelope.
Diane opened it. A single slip of paper inside, the kind torn from a notepad. Four words in careful bookkeeper's handwriting.
She read it and felt something shift completely in the room, not just in the air but in her understanding of the past three days, the past four years, everything she thought she had been looking at from a safe distance that had in fact been happening right beside her the whole time.
She passed the slip to Adrian without a word.
He read it. His expression didn't change but she watched his eyes and she saw the moment of impact, brief and contained and real.
He set the slip down on the table.
The name written on it was Emeka Okonkwo.
Adrian's father was O.A. His father was the silent partner. His father had been receiving trust payments from the Marchetti family since before Adrian was born, in exchange for something agreed in 1974 that nobody was supposed to ever find out about.
"He's not trying to delay the clause," Adrian said. Very quiet. Very still. "He's trying to prevent it because if the clause activates, the sealed letter gets opened. And the sealed letter names him." He looked at Diane. "Everything he's done — the surveillance, Raymond, Kelvin, Zara — it's all been about keeping that letter closed."
"What did he agree to in 1974," Diane said. "What was worth thirty years of quarterly payments."
Nobody answered because nobody in the room knew yet.
Adrian's phone buzzed. He looked at the screen and something changed in his face for the first time that morning, something she hadn't seen before. Not fear exactly. The thing that lives next to fear in people who don't allow themselves to feel it directly.
"My father just arrived in Lagos," he said. "He's at my house."
