The charity event is for pediatric burn care, which is why Nadia is there, moving through the room in a green dress and the particular ease of a person who is good with other people in contexts that require it.
Gideon is not good at these events. He comes because Dr. Morrison from the board expects it, and because it is politically necessary, and because he is enough of a realist to understand that the operating rooms he needs to do his work cost money that comes from evenings like this one. He drinks sparkling water. He shakes hands. He says the right things in the right order and gives nothing away.
He is very good at the surface of this, even if the interior is something he performs.
At eight-seventeen, he is standing near the window talking to a cardiologist named Patterson about a shared patient when he becomes aware of someone entering the room who is not like the other people in the room.
He cannot say exactly why he knows this immediately. It is something in the way the man moves — unhurried, watchful, with the quality of someone who is always locating exits. The man is heavyset, in his early fifties, wearing a tie that does not go with his jacket. His glasses are thick-framed, and behind them his eyes are doing something that has nothing to do with the charity auction happening near the far wall.
He is reading people.
Gideon excuses himself from Patterson. He picks up a glass from a passing tray and carries it toward the window, near the edge of the room, where he can see the space clearly.
The heavyset man makes his way through the room with patience. He stops to speak to someone near the entrance. Then to someone near the bar. Then he turns, and his eyes find Gideon across the room, and there is a brief, absolute stillness before he begins moving in Gideon's direction.
Gideon does not move.
"Dr. Vale." The man extends his hand. "Ray Donahue. FBI. Behavioral Analysis."
Gideon shakes it. Donahue holds on a beat too long. Not aggressive — just deliberate. Just enough to be noticed.
"Interesting hands, Doctor," Donahue says, releasing the grip. "Very steady."
"You have to be." Gideon meets his eyes. They are a very neutral gray, those eyes. They are doing the same reading they were doing across the room. "In my line of work."
"So do I." A pause. The corners of Donahue's mouth shift slightly — not quite a smile. "Beautiful event. The foundation does important work."
"It does."
"Are you a regular supporter?"
"I have colleagues on the pediatric floor."
"Of course." Donahue looks out at the room. His posture is casual and every part of it is calculated. "I've been in Philadelphia six days. I keep hearing your name. Apparently you're the best trauma surgeon in the city."
"I'm adequate."
"That's very modest." He looks back at Gideon. "I have a feeling you're not modest."
Gideon takes a sip from his glass. "Are you here professionally, Agent Donahue?"
"I'm always here professionally." Another shift at the corners of his mouth. "Enjoy your evening, Doctor."
He walks away. Gideon watches him go — the unhurried pace, the watchful eyes, the way he navigates the room without touching anyone.
He is, in a word, precise.
Gideon turns back to the window. The city is visible through it, dark and wet and usual.
He stands there for a moment, very still, feeling the weight of something that has just shifted.
The game, he understands, has started.
He finishes his water and goes to find Nadia.
