They took Elise Hartwell at the gallery.Priya had considered other locations — her apartment, a precinct interview room, some neutral ground. She had chosen the gallery because she wanted to see Elise there, in the space she'd built over twenty-two years, when the world she'd constructed around the alibi finally closed.It was a Wednesday morning. The gallery was open. Three visitors moved quietly through the anniversary show, which was still installed, which would remain installed until the estate proceedings and the fraud investigation resolved themselves, which would take months. The art would hang in the silence of a place whose owners were both gone, in different ways.Elise was in her office on the second floor.When Priya and Webb came through the door, she looked at them. Just looked. No surprise — the composure Nadia had described was there, but Priya could see now what was underneath it. Not guilt, exactly. Something more pragmatic than guilt. The composure of someone who had known this was coming and had decided to meet it as she met everything: precisely."Elise Hartwell," Priya said, "you are under arrest for the murder of Conrad Vane."She read the Miranda rights. Elise listened without expression.Webb moved to take her arm, and she stood without assistance, with the small dignity of a woman who was not going to be guided.At the door of her office, she stopped."Can I ask one thing?" she said.Priya looked at her."The program," Elise said. "You found it."It was not quite a question. It was the statement of someone checking the accuracy of their own failure point."The event manager kept an archive copy," Priya said.Elise was quiet for a moment. Something moved in her face — not regret, exactly. More like the specific expression of a person who has found the flaw in their own engineering after it's too late to fix it."I knew about the archive," she said. "I just assumed—" She stopped."You assumed it was recycling," Priya said."Yes." A pause. "A reasonable assumption.""Most of the time," Priya said. "Not always."They took her through the gallery. The three visitors looked up briefly and looked away — the careful New York instinct to give people their dignity in difficult moments. The art hung in its still, expensive silence. A Hopper. Two Basquiats. A painting whose provenance, Priya now knew, had been written by a man who was better at creating stories than telling the truth about them.At the entrance, the city was doing what it did — moving, sound-making, indifferent.Elise Hartwell walked out of the gallery she had built for the last time.— ◆ —In the car, Webb said: "The glass alibi.""Yes.""She built the perfect alibi. Nine cameras, two hundred witnesses, not a second out of sight.""The perfect alibi," Priya said, "always assumes the question will be where you were when it happened. She answered that question before anyone asked it." She looked out the window. "She didn't account for the question being what you put in his pocket ninety minutes earlier."Webb drove."You saw the program on day one," he said. "The footage, seven-eleven. You saw it and you went straight for the program.""I saw her hand it to him," Priya said. "And I thought: why would you specifically give your business partner a program that's available on every table? What's in the giving of it that requires you to be the one to do it?" She paused. "Everything visible has a purpose. The glass alibi was visible. That was its purpose. Which meant the murder wasn't visible. Which meant it was somewhere in the ninety-six minutes before he died." She looked at the city. "She built a box out of glass so everyone could see she was clean. The mistake was that the box itself was evidence.""That she'd built it," Webb said."That she'd needed to."
