Chương 7
Receipts.
Two pens that barely worked.
And a small black notebook.
I stopped breathing.
Cho said my name.
I barely heard him.
The notebook contained handwritten notes from the anomaly investigation.
Not evidence.
Not conclusions.
Questions.
Credentials.
Dates.
Names I had copied while trying to understand who had touched the vendor records.
Julian’s name appeared more than once.
So did the name of his supervisor.
So did another name I had not identified.
“What was he doing with it?”
Hale said, “Security doesn’t know yet.”
My phone buzzed again.
This time it was Sergeant Patel.
I looked at Cho.
“Answer it.”
I stepped away from the microphone.
“Sergeant?”
“We have your husband downstairs.”
Her voice was clipped.
“Is he arrested?”
“No.”
The disappointment that moved through me was immediate and shameful.
“He entered a restricted university area after being told not to, so we’re documenting that.”
“My bag?”
“We have it.”
“Did he open it?”
“I can’t tell you that yet.”
“Why not?”
“Because he says it belongs to him.”
I almost laughed.
“It has my name inside.”
“I understand.”
“No, my actual name is stitched into the inner pocket.”
“I said I understand.”
Her tone softened slightly.
“We’re preserving it as we found it.”
I looked back at the committee.
Twenty-three people were pretending not to listen.
“What did he want?”
“He says he came to give you materials you forgot.”
I closed my eyes.
Of course he did.
Reasonable Julian.
Helpful Julian.
The devoted husband carrying his unstable wife’s forgotten work bag to campus.
“Do you believe him?”
“That isn’t the question I’m working on.”
“What question are you working on?”
“Whether he violated an instruction to stay out of this building and whether there’s probable cause connected to what you reported this morning.”
“I didn’t report anything.”
“You told Professor Hale you were assaulted, and she relayed enough information to trigger a safety response.”
“That’s not a statement.”
“No.”
I heard movement behind Patel, then a man speaking indistinctly.
“Ms. Mercer, I need to ask you something specific.”
“Okay.”
“Did your husband have permission to take your work bag from your residence?”
“No.”
“Did he have permission to bring it here?”
“No.”
“Does it contain university property?”
“Yes.”
“What?”
“My current access card isn’t in there, but there are research notebooks, possibly an old badge, and some project documentation.”
“Anything confidential?”
I looked at the amber network still glowing on the auditorium screen.
“Yes.”
“How confidential?”
“Potentially enough to matter.”
Patel became silent for half a second.
“Then don’t touch the bag when we bring it up.”
“Why?”
“Because I want to document its condition first.”
That sentence shifted something.
Until then, the bag had been another piece of my life Julian had taken and rearranged.
Now it had become an object with a condition.
An object with custody.
An object he could not explain merely by saying I was upset.
“When are you bringing it?”
“After we photograph it.”
“I have to finish my defense.”
“I know.”
I nearly asked how she knew.
Then I remembered the entire building knew by now.
“Is he leaving?”
“He says he intends to wait outside campus property.”
“Can he?”
“Unless circumstances change, yes.”
A hot wave of anger rose through me.
“He held me down while his mother cut my hair off.”
The auditorium became utterly quiet.
I had forgotten I was still holding a microphone in my other hand.
My own voice had gone through the speakers.
Patel paused.
“I heard you.”
I stared at the microphone.
Hale crossed the distance between us and gently switched it off.
My face burned.
“I’ll give you a statement after this,” I told Patel.
“Okay.”
“And Sergeant?”
“Yes?”
“Don’t give him my bag.”
“We won’t.”
I ended the call.
No one in the room looked comfortable.
Ben had stopped pretending not to stare.
Professor Foster’s mouth was slightly open.
Cho rubbed the bridge of his nose.
I wanted the floor to split beneath me.
Hale leaned close.
“You can stop.”
“No.”
“No one here would hold it against you.”
“That’s not why.”
She waited.
I glanced at the screen.
The amber paths looked almost absurdly calm.
Lines.
Nodes.
Probabilities.
A system did not care whether its hidden structure was humiliating.
It simply behaved according to what was actually connected.
“I’m already here,” I said.
Hale’s eyes stayed on mine for another moment.
Then she returned to her chair.
Cho put his glasses back on.
“We will resume when you are ready.”
I wiped my palms against my trousers.
“I’m ready.”
The next forty minutes were the hardest academic work I had ever done.
Not because the questions were cruel.
Because they were fair.
Foster challenged whether my anomaly thresholds could generalize across industries.
Ibarra forced me to defend a design choice I had regretted for two years.
Cho asked why I had not incorporated causal inference into the final architecture.
I told him because I had tried and failed.
“How badly?”
“Expensively.”
He almost smiled.
“Explain.”
So I did.
I explained the failed implementation, the compute costs, the instability, and the three months I had wasted trying to salvage it because I was too stubborn to admit the approach was wrong.
Hale asked what I would change if given another year.
“First?”
“Yes.”
“I’d stop pretending interpretability is a secondary problem.”
She nodded.
“And second?”
I thought about it.
“I would design the data governance layer before the model.”
That answer changed the room.
Cho leaned forward.
“Why?”
“Because a system that can reveal hidden relationships creates responsibilities the original research question doesn’t capture.”
No one spoke.
I looked at the amber paths.
“You can build a model to find what people didn’t know was connected.”
My throat tightened, but I kept going.
“That doesn’t mean you know what those connections mean.”
At ten twenty-one, they sent me into the hallway.
The defense was over.
May you like
The committee would deliberate without me.
I sat on a bench outside with my hands between my knees.
