The restaurant on Walnut Street has a service entrance on the alley side that the catering staff uses between seven and nine PM. After nine, it is locked from the inside by a bar mechanism that can be released with specific pressure applied to the lower left corner of the doorframe, where the seal is worn. Gideon found this on the third reconnaissance visit. He did not test it then. He tests it tonight.
The door opens.
He is inside for nineteen minutes. He knows this because he counted.
Kelley is in the private dining room, which opens off the main corridor through a door with a frosted glass panel. Through the glass, Gideon can see the shapes of four men around a table. He does not need to go in. He does not need to be near Kelley. He needs to be in the corridor for forty seconds, where the air handling system makes the particular kind of contact he requires technically possible.
This is the part he does not explain to himself in detail. He is a surgeon. He knows what the body can absorb through certain routes of entry that leave no external trace, and he knows exactly how to deliver it without proximity.
He is in the corridor for thirty-seven seconds.
He exits through the service door.
He is two blocks away before he notices it.
The glove on his right hand — the thin surgical glove, the powder-free kind — has a tear at the base of the index finger. A small tear. The size of a pinhole. He does not know when it happened. He does not know if the tear occurred before or during or while he was in the corridor.
He stops walking.
He is standing on a side street. A couple passes at the far end. A taxi. The ordinary city.
He looks at the glove. He pulls it off carefully, then the other one. He puts both in the separate bag. He looks at the index finger of his right hand. Nothing visible. Nothing that can be seen.
But a pinhole is still a pinhole.
He begins, very calmly, to trace his movements backward through the nineteen minutes. The corridor. The door. The doorframe.
The desk in the corridor, near the door. He had touched the edge of it — steadied himself on the corner for one second as he made the turn.
His heart does not speed up. This is not bravery. This is the training. When something goes wrong, you do not panic. You assess. You determine the probability of consequence. You act accordingly.
He walks the two blocks to his car.
He sits behind the wheel.
He runs the assessment: one corner of a desk. The exterior side. Brief contact, low pressure. The probability of a full print is very low. The probability of a partial is higher.
He starts the car.
He does not know, yet, that two days from now a federal agent is going to find exactly what he is afraid of and circle it in red.
He drives home. His hands, on the wheel, are perfectly steady.
They have not failed him yet.
