Howard met his eyes. "I will."
He picked up the cup with a gloved hand, slid it carefully into the evidence bag, sealed it, and walked out the way he had come. The door clicked softly behind him.
Edward stood by the window for a long moment after he was gone. He looked at the river. He looked at the small barge that was now almost out of sight around the curve.
He thought about the seventeen companies. He thought about the three board meetings scheduled for this week. He thought about the lawsuit that had been filed against the medical division in April, and about the merger he had blocked in March, and about the partner he had quietly forced into retirement in January because the man had been moving funds in a way that did not have a clean explanation.
Any one of them, or none of them, or a name he had not yet thought of.
He turned around. Marcus was watching him from the sofa, the small empty bottle of chocolate milk now set carefully on the side table beside him, the cap screwed back on as if the boy had been raised to leave a place exactly as he had found it.
"Marcus," Edward said quietly, "I think you should know something. You did not just save my life this morning. You did something much harder than that. You made a decision that most grown men in this building would not have made. You saw something wrong and you did not look away. Do you understand how rare that is?"
The boy thought about it. "My mom looks at things," he said finally. "She taught me to look at things."
Edward sat down slowly in the armchair across from the sofa. For the first time that morning, he was not behind a desk and the boy was not on the other side of a room. They were two people sitting in a quiet space with the city laid out behind them.
And Edward asked the question he had been wanting to ask since the boy had first stepped through the door: "Tell me about your mother."
The boy's face changed in a small way that Edward recognized. It was the way a person's face changes when they are about to talk about someone they love and are trying not to make it sound bigger than it is.
"Her name is Doreen Hill," Marcus said. "She has worked in this building for almost four years. She used to work two jobs, but last year she stopped the second one because her back started hurting. Now she just works here. She wakes up at 4:00 in the morning. She makes my breakfast and packs my lunch before she leaves. She comes home at 6:00. She makes dinner. She helps me with my homework. She reads with me before bed. On Sundays, we go to church, and then we go to the library."
"Where is your father?"
The boy looked down at his hands. "He died when I was four. He was a bus driver. He had a heart attack while he was driving. He pulled the bus over and parked it and made sure all the passengers were okay before he called for help. The doctor said if he hadn't pulled over, he might have lived. But he didn't want anyone to get hurt." The boy paused. "My mom keeps a picture of him on the wall by the kitchen. She talks to it sometimes."
Edward did not say anything for a moment. He was thinking about the kind of woman who would raise a boy like this on the wages of a cleaning crew shift, who would teach him to look at things, who would send him into the world with the conviction that doing right was its own reward even when it cost you. He was thinking that he had walked past her in the lobby a hundred times without knowing her name.
"Marcus," he said, "when this is over, your mother and I are going to have a conversation."
The boy looked up quickly. There was a flash of something in his face that was not quite fear, but was close to it. "She didn't do anything wrong, sir."
"No, no, that is not what I mean." Edward leaned forward slightly. "I mean that I owe her something. I owe her something for raising the kind of boy who walked into my office this morning. I do not yet know what that something is. I will figure it out, but she is going to know my name the way I now know hers."
The boy thought about that. Then he nodded once, and his shoulders settled the small fraction that they had been holding tight.
There was a soft buzz from the desk. Edward stood and picked up the phone. It was Howard, and his voice was low and quick.
"Edward, I am in the catering hallway now. There are two carts here that match what the boy described. I have located the camera feed from this morning between 7:30 and 8:10. There is a six-minute gap in the recording. The system says it was a routine refresh. It was not. Someone pulled the feed manually and re-uploaded a loop. They were sloppy. The same pigeon flies past the window three times in two minutes. I have the original somewhere on the backup server, and I am pulling it now."
"How long?"
"Forty minutes for the footage. The lab is faster; I should have a preliminary on the cup within the hour."
"Howard, the camera pulled... that means someone in the building."
"Yes."
