“Tomorrow,” I said, “we tell the detectives everything.”

Iris nodded once.

“And if they don’t believe me?”

“Then they can decide that after hearing the facts.”

Chapter 10: What Was Inside the Wall

The detective who reopened Mara Voss’s file was named Nina Calder.

She had not worked the original disappearance and did not pretend she could resolve it in an afternoon.

Calder interviewed Iris and Leah separately, obtained the original camera recordings, and asked to inspect the blocked basement doorway.

A county building official accompanied the work crew because the wall carried electrical conduit and might affect structural supports.

Luis carefully opened a narrow section beside the steel frame.

Behind it stood a small room lined with plain wooden shelves.

The air smelled of dry plaster and old cardboard.

A single cabinet rested against the far wall.

Its doors were locked with a brass hasp.

Inside the room were boxes of lesson plans, old photographs, and a portable typewriter.

The cabinet itself bore a label written in Margaret’s unmistakably careful handwriting.

“Mara’s account.”

Calder documented the discovery before arranging for the cabinet to be opened by an appropriate technician.

I did not touch it.

I stood beside Luis while he looked at the label.

“My uncle said there was something in this house that mattered more than the house,” he murmured.

“Did he say what?”

“No.”

The cabinet contained three ring binders, a stack of copied invoices, and a handwritten diary.

The diary began in March 2007 and ended on the morning Mara disappeared.

Calder would not share its contents during the investigation.

She did, however, confirm that it referred to Henley and to a contractor named Arthur Vale.

I had expected the discovery to make Iris grateful.

Instead, she became visibly frightened when Calder told her the cabinet had been found.

“He’s going to know,” Iris said.

“Who?” Calder asked.

“Arthur.”

“How would he know?”

Before Iris could answer, a black sedan slowed beside the curb.

It passed our houses without stopping.

Iris stared at its rear window until it vanished.

Then she said something I would remember for the rest of the year.

“Because I told him where the cabinet was three days ago.”

Chapter 11: Three Days Earlier

Detective Calder did not raise her voice when Iris confessed that she had spoken to Arthur Vale.

She simply asked Iris to start at the beginning of their last conversation.

Iris described a call received on Wednesday evening from a number she did not recognize.
