I asked neighbors with relevant firsthand observations to contact the appropriate authorities privately.

The message was less satisfying than the reply I had deleted.

It was also less likely to harm anyone.

A woman named Helen Cho sent me a private message ten minutes later.

She said her mother had briefly stayed at Vivian’s home during a difficult transition after surgery.

Helen wanted to know why I was asking people to report observations.

I asked if we could talk by telephone rather than in the public thread.

She agreed.

Helen worked as an elementary school librarian and lived forty minutes away.

Her mother, Ada, had been discharged from a rehabilitation facility with instructions for supervised mobility exercises and regular medical follow-up.

Vivian’s service advertised short-term residential assistance with meals and transportation.

Helen had paid a deposit and a week of fees.

She removed Ada after four days because her mother reported that the doors were locked from the outside at night.

Vivian said the locks prevented wandering.

Ada said nobody had told her she would be unable to open her own door.

Helen asked for a refund and received a partial payment after threatening to file a complaint.

“I thought it was just a bad business,” she said.

“I didn’t know she had moved other people into the house.”

I asked whether Ada had met Ruth Halpern.

Helen took a moment to think.

“There was a woman who liked crossword puzzles.”

“Do you remember her name?”

“I remember my mother saying Ruth because she complained that Ruth borrowed her pencil.”

The name made my stomach tighten.

I asked Helen to share what she knew with Simone rather than trying to investigate herself.

She promised she would.

“Do you think my mother was in danger?” she asked.

I could not answer that honestly without qualification.

“I think she deserved clearer information and the ability to leave,” I said.

Helen was quiet.

“She kept asking whether she had done something wrong by wanting to come home.”

I thought about June and the fear in her voice.

“She did nothing wrong,” I said.

Helen thanked me and hung up.

I sat at my desk and looked at the pool maintenance invoice.

What Vivian had done to my property was expensive and exhausting.

What she might be doing to the people in her house was harder to measure.

I had spent too much time thinking of her as a terrible neighbor.
