Pamela doesn't answer her phone on a Wednesday morning.
It happens. She goes into field sessions, data collection, hours where the phone is in a bag and the work is in her hands and the world can wait. I know this about her. It's Wednesday and the site three panel submission is due Friday and she's probably at the Crane Street site taking baseline readings.
I call twice and leave a message the second time.
At noon I get a call from a number I don't know. A man's voice, careful: he's a graduate student in Pamela's department, he's calling because her supervisor asked him to, because Pamela didn't come to the lab this morning and she'd had a nine o'clock meeting she never missed and nobody has been able to reach her.
I'm already standing up.
I drive to her apartment. The building super lets me in. Her apartment is unlocked, which is wrong. Everything in it is where it should be: laptop closed on the desk, books where she left them, coffee cup from this morning half finished on the counter.
Her field kit is gone. The small camera. The sample vials and the labeled case she uses for site work.
She went out to work.
I call the graduate student back and ask which sites she'd been planning to visit this week. He gives me three addresses. I go to the first one: the Crane Street site, the one that got the second remediation order.
Her car is parked a block away.
The site itself is a cleared lot where the demolition happened eight years ago. There's a bench at the edge where Pamela sets her kit up when she's taking readings. The bench is empty. The kit isn't there.
I walk the perimeter of the lot.
At the far edge, near the fence that borders the adjacent drainage channel: three sample vials in a row on the ground. Labeled in her field handwriting, smaller than her usual, more deliberate. Capped and standing upright, placed carefully, the way she places them when she's setting up a sequence.
No Pamela.
The fourth vial would go here, I know without measuring. The sequence is obvious. It's not there. The camera isn't there. The labeled case isn't there.
She stopped in the middle of something.
I look at the drainage channel on the other side of the fence. The Crane Street site sits at the convergence point of three contamination plumes, the same convergence she'd mapped on the floor of her apartment two weeks ago. The drainage channel runs along the property line. It's been active recently. I can see the water line on the concrete, higher than it should be for this time of year. A drainage pipe feeding it from the north has been leaking, from the look of the staining. Slow accumulation. The kind of thing the city files as maintenance pending and doesn't act on.
The kind of thing the contractor certifications called compliant.
I take the right glove off.
I crouch at the edge of the lot and press my palm flat to the ground beside the three vials.
What I get comes in before I'm ready for it.
Curiosity. Her curiosity, specific and warm, the texture I'd read off her hand in the East End doorway a year ago but sharper now, more recent, alive in a way that makes the past-tense quality of what I'm reading register with a delay. She'd been here this morning. She'd been interested in what the readings were showing. The soil data was doing something she wanted to document.
And then: attention redirected. Not fear. She'd seen something near the fence line, an anomaly in the water level or the staining on the concrete. The specific quality of a scientist who has noticed something and is going to look at it more closely.
The impression moves. She moved. Toward the fence.
Then the sequence breaks.
Not the way a read ends when it runs out. The way something ends when the person it belongs to is no longer there to generate it. An absence that has a shape, the shape of someone who was present and then wasn't, and no continuation after.
I hold my palm against the ground and there's nothing left to hold.
I pull my hand back.
I stay crouched at the edge of the lot for a long time.
Three sample vials in a row. The fourth position empty. A drainage channel on the other side of the fence carrying water from a leaking pipe that the city filed as maintenance pending. The convergence of three contamination plumes that Pamela had been mapping for two years because the playground was still there and the children were still on it and she hadn't found the chain yet.
She found it.
She followed it to where it went and it took her somewhere she couldn't come back from.
I stand up. I take out my phone and call Renee.
"Pamela Isley is missing," I say. "Crane Street. I need a team and environmental hazmat at the drainage channel along the east fence line."
I say it the way it is. I keep my voice level. I put the phone away.
I stand at the edge of the lot and look at the three vials and the empty fourth position and the fence and the channel beyond it.
The contamination she'd been mapping for two years. The sites she'd documented, the soil samples in their labeled rows, the review panels and the remediation orders. Mooney Street. Crane Street. The playground and the children and the iron content at four times acceptable levels and the contractor who certified compliant and paved over it.
Two sites remediated.
Seventeen on the list.
The hazmat team finds traces in the drainage channel that afternoon.
Biological material and a field kit, the camera, the labeled case, one glove. Not Pamela. The channel connects to a broader drainage network under the East End that hasn't been fully mapped. The hazmat supervisor tells me, carefully, that the contamination levels in the channel are significant. That anyone exposed to the water at the concentration present would have experienced acute chemical toxicity. That recovery, in those conditions, is unlikely.
He says unlikely with the specific care of someone who means something else.
Renee files the missing persons report herself. She does it with the same thoroughness she applies to everything. When she's done she looks at me across our desks for a long moment.
There's nothing to say.
I go home and sit on the kitchen floor with the radiator making its noise. I don't open the notepad. I sit in the dark until the radiator stops making its noise and the city outside goes quiet in the way it goes quiet at three in the morning, which isn't quiet, just a different register of the same sounds.
I know what happened. I know it in my hands and my chest in the place where I know things I can't put in a report.
She followed a contamination plume to its source and the source was the same infrastructure that processed everything in this city: the buried problem, the certificate that said compliant, the gap between what was on paper and what was underneath. Dulmacher didn't touch her. He used the city's existing arrangement and she walked into it because she'd been following it for two years and didn't know what else was using the same ground.
I sit with that until it becomes something I can carry instead of something that's carrying me.
Then I get up. I turn the radiator on. I go to work.
Tomorrow Dulmacher is still in the city.
There's still a case to build.
