"Your system administrator writes code I respect," I say. The admission costs something, and I deliver it flat, stripped of inflection, because inflection would give it a weight I'm not ready to carry in front of a woman who reads subtext the way I read encryption. "The encryption signature is elegant. Conservative foundations, creative implementations. Whoever designed your security infrastructure understands systems at a level I rarely encounter outside my own work."
"And that was sufficient reason to compromise your anonymity?"
"That was sufficient reason to send a warning. Compromising my anonymity was the cost, and I calculated it before I typed the word."
Victoria is quiet for a moment, and the silence is deliberate. Intelligence professionals use measured pauses to create space for the subject to fill with information they didn't intend to volunteer. I recognize the technique because GCHQ taught it to me, and recognizing it doesn't make it less effective.
"The Committee's weapon targets the human element," I say, filling the space because the alternative is sitting in silence while Victoria studies me like a cipher she hasn't cracked yet. "It goes after communication channels, maintenance routines, the points of contact between an air-gapped internal system and the outside world. Whoever built it studied your system administrator's patterns long enough to map the rhythms and construct a key for one specific lock."
"You've mapped those patterns as well."
The observation is precise and carries an edge I can't deflect. Victoria isn't asking whether I mapped the patterns. She's asking what the difference is between my mapping and the Committee's.
"The difference is what I did with them," I say. "I found the door and knocked. They found the door and built a weapon."
Roman shifts in his seat. The movement is small, almost imperceptible, but the quality of his attention has changed from passive monitoring to active assessment. He's been listening to every word while appearing to watch the darkness through the window, and whatever conclusion he's drawing from this conversation will carry operational weight that Victoria's assessment alone might not.
Victoria reaches into the seat pocket and produces a bottle of water and a protein bar. She sets both on the armrest beside me with the same measured precision she applies to everything.
"Eat," she says. "You'll be briefed when we land, and I prefer my assets functional."
I take the water and leave the protein bar. I drink while the charter climbs through cloud cover, and the darkness outside the windows becomes absolute, the dense black of altitude at night where the ground has disappeared and the sky hasn't replaced it with anything recognizable.
My fingers tap against the bottle, working through the problem. Victoria wants to know if I can be trusted. The Committee is hunting me. Echo Base is hours away, hidden inside a mountain I've imagined but never seen.
Somewhere inside that mountain, a system administrator is awake because the system administrator is always awake, and the cipher I sent through his door is sitting on his screen like a stone dropped into water, the ripples carrying me toward him at cruising altitude.
The protein bar is still on the armrest. I pick it up and tear the wrapper with my teeth because both hands are occupied, one holding water and one tapping rhythms against my thigh.
Victoria watches me eat with the satisfaction of a woman whose orders are followed even when they aren't phrased as orders.
The flight settles into a rhythm of its own, engine noise and cabin pressure and the occasional turbulence that makes the wings flex and my stomach clench. I've spent two years inside a building, and the physical reality of being suspended in the atmosphere inside a metal tube is requiring more adaptive processing than I'd like to admit.
Victoria works on her tablet. Roman is still against the window, his breathing even enough that he could be sleeping except that he doesn't sleep on operational transports. His eyes are closed and his posture is relaxed, but he is fully aware of every sound in this cabin. My breathing rate, the frequency of my finger-tapping, the precise moment I finish the protein bar and fold the wrapper into a square and tuck it into the seat pocket because leaving trash in a borrowed space is a habit I can't break. He catches all of it without opening his eyes.
Time passes. I don't sleep. My bag sits on my lap and the drives inside it hold the weight of years, and the flight carries me west across a country I've barely seen from the outside in over a year.
Somewhere over the Midwest, Victoria speaks again.
"You'll be hooded for the final approach to the facility. Standard protocol for unverified personnel. It isn't personal."
"I understand."
"I expect you do. You also understand that the people inside that mountain have been operating under threat conditions for years and that a stranger arriving with intelligence about theirsystems will be treated with caution regardless of the warning she sent."
"I'd think less of them if they weren't cautious."
Victoria closes her tablet and the conversation with the same decisive motion.
The descent begins somewhere over western Montana. I feel it in my ears before the pilot announces it, the pressure change settling into my sinuses with the discomfort of altitude loss. Through the gap at the edge of the window shade, mountains fill the frame, ridgelines stacking against a sky that carries the flat, pewter quality of high altitude. Forest everywhere. The vast, indifferent geography of a state with more land than people, and somewhere in that geography, a mountain with a facility carved into its heart and a server hum I've been listening for across months of intercepted signals.
The wheels touch down on packed earth outside. The aircraft shudders, slows, taxis to a stop. The engines wind down into a silence so complete it feels like the world has been muted.
Victoria produces a hood from the seat pocket, black fabric that is lightweight and opaque. She holds it up without apology.
"When we're inside," she says, "I'll remove it myself."
I nod. She places the hood over my head, and the darkness is total. The last thing I see before the fabric settles is Roman's hand on the cabin door, steady and certain, opening the way into whatever comes next.
