I wanted to be careful.

“I’ve seen him in her kitchen, but I can’t tell you what he was doing.”

“That’s fair,” she said.

The officers separated us and took statements.

They photographed the broken basin and collected the audio from Gloria’s phone with her permission.

Naomi explained that attacking someone could not be excused by receiving a frightening message.

Gloria sat on the edge of the police car’s back seat and kept asking one question.

“Is Molly coming home?”

The answer never changed.

The police could not promise her that.

Derek took several steps toward his mother and demanded to speak with whoever had lied to her.

Officer Barnes told him to remain where he stood.

Derek looked indignant.

“I’m her son.”

“And we’re taking your mother’s statement,” Barnes replied.

“She attacked a man because he was keeping her granddaughter,” Derek said.

“That’s an allegation, not an established fact,” Naomi answered.

I had never heard an officer say a sentence that sounded so ordinary and so necessary.

For months, our block had treated whatever Derek said as the closest available thing to an explanation.

Now the distinction between a claim and a fact was visible to everybody.

At the station that evening, I sat in a narrow interview room with a glass of water I had not touched.

My cheek had begun to swell.

I wanted an ice pack, a hot shower, and a return to the version of Thursday in which my biggest problem was a deadline for a museum exhibit.

Instead Detective Alina Ward arrived with a legal-aid attorney named Mina Patel.

I had met Mina four weeks earlier when she commissioned me to evaluate some audio messages for a client facing financial exploitation.

She had not told me the client’s name.

Alina laid three photographs on the table.

The first showed the waveform from the message Gloria played.

The second showed a message sent to a retired machinist across town.

The third showed an audio attachment delivered to a woman in Toledo who believed her missing brother needed bail money.

“What do these have in common?”

Alina asked.

“A repeated metallic click about eight seconds in,” I said.

“Anything else?”

“The background noise.

It looks like a room tone loop rather than a continuous recording.”

Mina said nothing, which told me she was allowing the detective to control the interview.

“Can a person make a recording of somebody saying words they never said?”

Alina asked.
