The Zurich witness's name was Mireille Devereux. She was sixty-one years old and had been living under a false identity in a suburb of Geneva for eleven years because she was afraid.
She should have been afraid. She knew what she saw and she knew what it cost to see it.
She arrived on Tuesday and was installed in a secure location I wasn't told. I knew she was in the city because Zion's entire affect changed — he became more compressed, more precise, the quality of someone approaching something important and handling every other variable with extra care.
On Wednesday afternoon, while Mireille Devereux was across town giving a formal statement to Adaeze and two investigators, I was in Zion's office when his phone rang.
He took the call. His face did not change.
When he ended the call, he said: "Elara knows she's here."
"How?"
"We don't know yet." He stood. "We need to move Mireille tonight. The location is compromised."
"Zion—"
"The case is intact," he said. "Her testimony has been recorded. The legal chain is protected. What we need to protect now is her." He looked at me. "I need you to do something that is not in your brief."
"What?"
"I need you to access Elara's monitoring system in real time and track whether she's moving assets tonight. If she sends people — we need to know before they arrive."
This was no longer data forensics. I looked at him. "If I do this—"
"You become more deeply inside this than you already are," he said. "I know. I'm asking. It is a choice you make yourself."
I thought about all the choices. The deleted email. The service corridor. The lake. The archive room kiss.
"Give me the access parameters," I said.
I spent four hours in Elara's system that night, watching her move. She was precise and she was angry — I can read anger in data, I have always been able to, and what she did that night had the signature of someone who had been patient for six years and was running out of patience. She sent three contacts toward the address she believed Mireille to be at. By the time they arrived, Mireille was not there.
At midnight I messaged Zion: She moved three assets. They've arrived at the compromised location. Mireille is safe.
His response: Thank you.
Then, a minute later: Come to my office.
I went. He was at the window — of course he was at the window — and when I entered he turned and looked at me with the weight of what that night had been.
"She knows we stopped her," I said.
"Yes."
"She'll regroup."
"Yes."
"The case—"
"The case is protected," he said. "Adaeze has everything she needs. The financial records, the testimony, the Node 7 documentation. The case is done, Nova." He looked at me. "We built the case."
I stood in the doorway of his office at midnight and understood what he was saying. The thing we had been working toward — the thing he had been working toward for eleven years — was finished. Done. In the hands of a legal process that would now carry it forward.
And I was still in the doorway, and he was still at the window, and the work that had held the space between us was done, and what was in the room now was not professional.
"She's not going to stop," I said.
"No. She'll keep looking for leverage." He paused. "Her leverage is you."
"I know."
"Which means—"
"Which means we finish this," I said. "Together. Her having leverage over me only works if I'm separate from you."
He looked at me across the room.
"Nova."
"I know," I said. "I know what I'm saying. I'm saying it anyway."
We finished the case. What is left is the thing the case was built around — the reason a precise and solitary man spent eleven years on something this difficult, and the thing he found along the way that he didn't plan for.
