Chapter 3
Isolde
The workshop is not what I expected.
I expected something feral. Something a pyromaniac would build — fuel cans stacked against walls, exposed wiring, rags soaked in solvent, the smell of accelerant heavy enough to make your eyes water.
I expected to walk in and immediately want to back out, because the contents of the room would tell me everything about the man and none of it would be good.
What I find instead is a chemistry lab.
It takes me a moment to register what I'm looking at.
The building is set apart from the rest of the compound on a small flat between the main yard and the western ridge, with its own concrete pad and its own ventilation system.
Inside, the front room is set up like a workspace — a long stainless-steel table down the middle, with two stools, a magnifying lamp, and a stack of labeled trays.
The back wall is shelving, floor to ceiling, with hundreds of glass jars and metal containers organized in a system I can read at a glance: alphabetical by base compound, color-coded by purpose, dated with neat handwritten labels.
The temperature in the room is sixty-eight degrees and stable.
There's a hum from a climate control unit I can hear but not see.
The floor is sealed concrete with a drain in the middle.
Two fire extinguishers are mounted within reach of any point in the room.
I stand in the doorway with the folder under my arm and I think: this man is not what I thought he was.
He's at the table when I come in, sleeves rolled to his elbows, sorting through what looks like field samples — small zip-top bags of charred debris, each one labeled with a date and a location and a code.
He looks up when my boots cross the threshold.
The amber eyes catch the overhead light and throw it back the way the prospect's eyes did at the gate, except his are quieter. More watchful.
"Sit," he says, and points at the stool across from him.
I sit. I set the folder down. I look at the room one more time because I'm still trying to recalibrate.
"You expected something different," he says. It isn't a question.
"I expected a pyromaniac's basement."
He almost smiles. The almost is becoming a thing I'm tracking.
The unburned half of his mouth lifts a fraction and the burned half follows by a smaller fraction, and the whole expression moves slowly across his face like he's not entirely sure his face will let him do it.
"Pyromaniacs are sloppy. I'm not a pyromaniac. "
"What are you, then."
He considers the question. He turns one of the sample bags in his hand. The charred debris inside it crackles softly.
"An arsonist is a man who has a job to do," he says. "A pyromaniac is a man who has a hunger to feed. The first one understands fire. The second one doesn't. The second one is the one you're trying to find."
I take the folder open and lay it out between us.
We work for three hours without a real break.
I show him my data. All of it. The chromatography from twelve scenes — the two destroyed sites had been on cycle four of the burn cycle and there was nothing recoverable.
The wind data. The topographical surveys.
The cross-referenced fire department reports from each of the fourteen jurisdictions, including the three I had to bribe a clerk in Tennessee to release because the fire marshal's office there was less than enthusiastic about my project.
I lay out my map with the red pins. I trace the geographic spread.
I explain how the spread clarified itself once I figured out what to look for.
He doesn't interrupt. He listens with a stillness that I'm starting to recognize as something like respect — though I'm not letting myself name it that yet.
He asks two questions in three hours. The first is about a fire in eastern Kentucky where the temperature data didn't match the others.
The second is about a residue sample from a fire in southern Ohio that had a slightly different lattice signature than the rest. Both questions are sharp enough that they make me re-examine my data on the spot, and in both cases the answer he's hunting toward turns out to be that the sample in question was an outlier that doesn't match the rest of the pattern.
Not the same fire. Not the same arsonist. Just a coincidence of geography that I'd been treating as part of the larger set.
He's a better fire investigator than I am.
That's a hard thing to admit. It takes me about an hour to admit it to myself.
I've spent fifteen years building expertise in this and he's spent fourteen, and his fourteen years have given him a precision that mine haven't, because he comes at fire from the other side.
I come at it as someone trying to stop it.
He comes at it as someone trying to make it do what he wants.
Both jobs require understanding fire. Only one of them requires commanding it.
After he asks the second question, he goes to the back wall and pulls down a logbook. He sets it in front of me. He says, "These are my jobs. Every one I've ever done. Date, location, compound batch, burn temperature, purpose. Look at it. See if any of them line up with your fourteen."
I open the logbook.
It's meticulous. It's the kind of record-keeping that would make any auditor weep with happiness.
Every entry is dated, signed, and cross-referenced.
The compound batches are documented with formulas and yield numbers.
The burn temperatures are recorded with the instruments used to measure them.
The purposes are written in a code I can't read at first glance but that he explains is a substitution cipher he developed for the club — readable if you have the key, unreadable if you don't.
I read through it.
His entries cover seven years. The earlier years are fewer — apprentice years, learning years.
The later years are more frequent. None of his fires overlap with mine.
None of them are in the right state on the right day.
None of them have the right temperature or the right compound code.
His batches don't fail. His sites don't leak.
The man in front of me has been keeping records that would, in any court in the country, exonerate him completely from the fires I came here about — if I were the kind of person who took a man at his own paperwork, which I'm not.
I tell him so.
"I can't take your word for these," I say. "You could have written them last night."
"I could have," he says.
"How do I verify them."
"You don't. Not on paper. You verify them by working with me, and watching how I work, and deciding whether the way I work is consistent with the records I'm showing you. That's the only verification you're going to get out of this room."
It's not the answer I wanted. It's the answer I would have given if our positions were reversed.
I'm a fire investigator. I know that paper trails can be forged and chemistry can be faked and the only thing that can't be faked is the way a man handles a sample under your supervision.
So I close the logbook and I push it back to him, and I say, "Then let's work. "
We work.
By midnight, we've found the pattern.
It's Ezra who finds it, but only because I gave him a piece he needed.
I lay out the geographic spread of my fourteen fires on the table — pins, dates, distances — and he sits across from me with a topographical map of the Sinners' territorial reach, and he traces the borders of what he calls our zone of operations.
His finger moves slowly. His finger has a scar that runs the length of the second knuckle, white against the brown skin.
"Look," he says.
I look.
My fourteen fires form a ring.
Not a perfect ring. There are clusters and gaps.
But once he draws the boundary of the Sinners' territory in pencil, the fourteen fires fall around it in a pattern that's unmistakable.
They're not random arson. They're not opportunistic.
They're a perimeter, drawn around the Sinners' territory with the meticulousness of someone who knew exactly where the borders were.
Someone isn't just framing the Sinners. Someone is encircling them.
I sit back on the stool. The realization rearranges everything I thought I knew.
"He wasn't trying to kill firefighters," I say. The words come out quieter than I meant. "He was trying to kill you. The fire that took my crew — they were collateral. They were just in the wrong part of the wrong forest."
Ezra is looking at the map. He doesn't look up.
"Yes."
"For two years I've been hunting a man who killed my crew on purpose. He didn't. He killed them by accident. He was making a perimeter and they walked into it."
"Yes."
I have to put my head in my hands.
It shouldn't be worse. It should be better, in some way that makes sense — at least it wasn't personal, at least it wasn't aimed, at least they died for something instead of nothing.
But that's not how grief works. Grief works backward.
If they died on purpose, they died as targets, and targets have meaning.
If they died by accident, they died as math.
They were a rounding error in someone else's plan.
Holt and Rodriguez and Kim and Diaz and Whitlock and Park and Trent — they were a rounding error.
I don't cry. I'm not going to cry in this man's workshop on the first day. I'm not.
But I have to put my head in my hands for a minute.
When I look up, Ezra is watching me. His hands are flat on the table on either side of the map. He hasn't moved. He hasn't reached for me. He hasn't tried to comfort me. He's just watching me, with the kind of attention I haven't gotten from another human being in two years.
I notice, in that moment, three things about him.
The first is that he doesn't touch. I'd already half-noticed it earlier in the day, but now, watching him sit perfectly still while I obviously need comfort, it lands.
Most men, even men who didn't know me well, would have reached for me.
A hand on the shoulder. A pat on the back.
Some gesture in the general direction of I see you and I am being kind.
He doesn't do any of that. He keeps his hands on the table. The space between us is deliberate.
The second is that he's holding himself in a particular way — his right side angled slightly away from me.
The burned side. I'd noticed earlier without naming it.
He always turns his left side toward people.
He talks to me with the unburned cheek forward.
When he reaches for something, he reaches with his right hand because the right hand is closer to me and the right hand keeps the scarred shoulder turned away.
The third is that he's hot. Even from across the table, three feet of stainless steel between us, I can feel the warmth coming off him. I noticed it in the bar. I'm noticing it now. It isn't a room warmth. It's a body warmth that escapes the body in a way human bodies don't usually do.
I don't comment on any of it.
I sit up. I wipe my face with the back of my wrist. I say, "Okay. So someone is encircling you. Why."
"To draw federal heat down on the compound," he says. "Probably to force law enforcement attention onto us so we can't operate. Probably as a setup for a move that needs us distracted or arrested or burned out before it happens."
"A move by who."
"That's what we're going to find out."
He gets up. He goes to a small refrigerator in the corner and pulls out two bottles of water.
He brings them to the table. He sets one in front of me without comment.
When he sets it down, the back of his hand passes within an inch of my hand on the table, and he flinches — not visibly, not so anyone watching would catch it, but I see the way his wrist twitches as he moves it back.
He sits back down.
"You flinch," I say, before I can stop myself.
He looks up. His face does the thing where it doesn't change but something behind it does.
"I'm aware."
"Why."
He's quiet for a long beat. He picks up his own water bottle. He doesn't drink it.
"People flinch when I touch them," he says. "After enough years of that, I flinch first. To save them the trouble."
I don't know what to say.
I look at his hands. I look at my own hand, the scarred one, the rope of healed tissue running down to my wrist. I think about the way his temperature reached me across three feet of table and how I didn't flinch.
I didn't even shift back. I leaned into it without thinking, because warmth is warmth, and I haven't been warm in two years.
I don't say any of this. I'm not ready and he isn't either.
I just say, "I don't flinch easily."
He looks at me. He looks at me for long enough that I have time to notice that the amber in his eyes isn't quite amber — it's something with green at the edges, something that gets warmer when the light moves.
He looks at me long enough that the room gets quiet in a way that isn't only acoustics.
Then he nods, once, and breaks the look, and goes back to the map.
We work for another hour.
When I finally stand up to go back to the cabin they've given me, my shoulders ache and my eyes burn and the workshop is full of the kind of late-night quiet that good work makes.
He walks me to the door. He stops two feet inside it, like he's not going to step out into the yard with me. He says, "Tomorrow. Eight."
"Eight."
"And Isolde."
I turn back. It's the first time he's said my name. He says it like it's a word he's never tried before.
"Yeah."
"I'm sorry about your crew."
He doesn't say it like a man performing sympathy. He says it like a statement of fact. Like the wind is from the southwest or the burn temperature was twenty-two hundred Celsius. I'm sorry about your crew. The fire took six people. I'm sorry that fire is the kind of thing that takes.
I nod. I don't trust my voice.
I walk out into the yard. The compound is dark and quiet and the mountain air smells like dry pine and old smoke. Behind me, I hear him close the workshop door.
I walk back to my cabin slowly, alone, with my hand pressed lightly to the scar on my left palm. The scar is cooler than the rest of my skin, the way old burn scars are. The night air is cool, too. Everything around me is cool.
Except the place on my forearm where his hand passed within an inch of mine. That place is still warm.
