He did not care that the room had recently appeared in a newspaper.

He cared whether a person could enter safely, switch on the lights, and leave without obstruction.

His ordinary questions were strangely reassuring.

I had spent months listening to people describe the basement as a secret chamber, a hiding place, or a scene of imagined danger.

Now somebody was asking about wiring and air circulation.

After he left, Luis and I installed a temporary workbench against the wall.

We found a box of old screws and sorted them into jars for future repairs.

I asked Luis whether he regretted accepting the renovation contract.

He considered the question before admitting that the delays had made him anxious about paying his crew.

I apologized for the uncertainty and thanked him for keeping the workers informed.

Luis said the men did not expect a perfect job, but they needed honest explanations when plans changed.

I realized that was also what Iris had denied me when she appeared at my door demanding entry.

She expected me to change my home without telling me the truth about why.

I placed the engineer’s report in a binder and labeled it for the next owner, whenever that might be.

A house could preserve difficult history without forcing the next family to rediscover every repair from scratch.

ADDITIONAL CHAPTER TWENTY-EIGHT: THE LOST RECEIPT

Nora Wynn called with news that her family had found another envelope among Beatrice’s effects.

It contained a taxi receipt, a list of groceries, and a short note Margaret had written about a visitor who needed to leave before sunrise.

The receipt’s date fell near the period when Mara was believed to have disappeared.

Nora asked whether I wanted copies before she contacted Calder.

I thanked her and suggested she send them directly to investigators so the original documents could be recorded properly.

Nora admitted she feared losing the papers after keeping them safely for so many years.

Calder arranged for the originals to be photographed and returned once they were no longer needed.

The receipt helped support a timeline already suggested by Beatrice’s appointment book.

It did not identify the passenger, and the driver’s name had faded beyond reliable reading.

Nora told Frances she was disappointed that the discovery did not settle everything.

Frances said the value of a document was not measured by the number of mysteries it solved.

Some documents mattered because they allowed investigators to reject an incorrect theory.
