Chapter 5

The base noise was still around us. Generators. Wind off the ridge. The distant complaint of the vehicle in the motor pool. But the space immediately around us had gone quiet in the specific way that happens when thirty people have simultaneously stopped producing sound.
Corporal Tate was no longer smiling.
Morrow was looking at me.
I looked at Ava Cross for three full seconds, reading the face that had given me nothing I could misinterpret — the stillness that was not passivity, the quiet that was not timidity, the eyes that were not performing anything for my benefit or anyone else's.
The transfer paper in my jacket pocket had a classification designation that told me I would not find her through normal channels.
The rifle case in her hand had corners worn in ways that suggested it had been to places that did not appear in public records.
The tattoo on her wrist was specific in a way that decorative ink is not.
And she had assessed my watchtower structure from the gate, in thirty seconds, more accurately than the engineering review I had requested four weeks ago and not yet received.
I turned to Morrow.
"Show her to Watchtower Three."
Morrow's face did something complicated. The performance he had been running for the past five minutes — the crowd management, the display of authority, the invitation for laughter at something that had turned out not to be funny — was now finished, and the face beneath the performance was not something he had planned for this particular morning.
He walked.

Ava followed him without looking back at the men who had been laughing, without looking at Tate, without looking at me. She walked past them the way she had walked in — like the crowd was a terrain feature rather than an audience, something you navigate around on the way to where you are going rather than something that requires a response.
That night, at 0300, the perimeter sensors went off on the northern approach.
Every man at Dust Bowl had learned over three months to treat the 0300 alert as a false positive — to roll over, listen for thirty seconds, and go back to the compromised sleep that was all any of us were getting. We had been conditioned by repetition to regard the northern sensor as unreliable, and conditioned men make the mistakes that conditioned men make.
The shot from Watchtower Three came before any of us had finished deciding whether to get up.
One shot. Then quiet. Then, over the radio, Ava's voice at the same flat register she had used to say her name at the gate.
"Single infiltrator. Northern approach. Confirm sweep."
Morrow ran the sweep himself. He came back with a face I had not seen on him before — not the face he wore when he was performing for a crowd, and not the face he wore when he was angry, but the face of a man who has been shown, with complete precision, the exact measurement of how wrong he was.

He did not say anything about it.
He did not need to.
