It mentioned that Margaret had declined to speak publicly about the case.

“My mother used to clean Margaret’s house,” Leah said.

“She knew where everything was kept.”

“Including whatever she placed under my window?”

Leah’s hands tightened around her paper cup.

“I didn’t know she had gone back.”

I showed her the camera still without handing over the device.

Her expression collapsed when she saw the canvas case.

“That’s the case she kept in the attic.”

“What was inside it?”

“She told me it held receipts from her cleaning business.”

I waited while Leah worked out how much she wanted to say.

Finally, she leaned forward.

“Three weeks ago, a man came to our house and asked if she’d found Margaret’s notebook.”

“Did she recognize him?”

“She said he had been looking for that notebook for eighteen years.”

The library’s quiet suddenly felt fragile.

Leah reached for the clipping again.

“My mother thinks Mara Voss disappeared because she tried to tell the truth about something Margaret kept.”

“What truth?”

“I don’t know,” Leah said.

“But a week before she died, Margaret called my mother and told her the house was finally going to be sold.”

Leah looked up.

“She told her to make sure the next owner never opened the wrong wall.”

Chapter 5: The Patch Beneath the Sill

Luis arrived the next morning with licensed electrician Jonah Mercer and a building inspector I had hired privately.

We checked the area around the window for wiring and unusual materials before removing anything.

Jonah found no live connection beneath the outer trim.

The inspector approved careful removal of the loose patch after examining the surrounding frame.

Luis worked slowly while I photographed each stage.

Beneath the fresh sealant sat a narrow brass tube no longer than my little finger.

The tube had been pressed into a drilled cavity in the old wood.

Its cap was wrapped in thin rubber to protect it from moisture.

Inside lay a tightly rolled strip of photographic film.

I expected paperwork, a key, or perhaps some kind of tracking device.

The film surprised everyone.

We did not unroll it in the sunlight.

A local photography archivist agreed to handle it in a controlled environment.

She confirmed that the material contained three frames and promised digital scans after examination.

Before leaving, she asked whether I knew who had stored it there.

“My neighbor,” I said.

“Possibly after removing it from somewhere else.”

I had to keep reminding myself that the video showed placement, not the entire history of the film.
