She glanced at the photograph, then toward the office behind her.
"Wait here."
She disappeared through a door.
Five minutes later, a man in a gray suit came out. He introduced himself as Deputy Records Director Alan Mercer.
He examined the file number, then asked me to follow him.
"We have limited access to some older development records," he explained. "Especially those involving municipal infrastructure."
"Why?"
"Because some documents contain engineering information that hasn't been fully digitized."
"That doesn't explain why I can't see the survey."
He stopped beside a locked cabinet.
"Mr. Harrow's company was involved in several disputes with the county. Some files were placed under administrative review."
"That was decades ago."
"Administrative restrictions don't automatically disappear."
He unlocked the cabinet and searched through several folders.
After a few minutes, he found one marked BRIAR GLEN — INITIAL PLANNING.
He opened it, examined the contents, and frowned.
"That's strange."
"What?"
"The original survey isn't here."
"Was it removed?"
"It appears to have been checked out."
"By whom?"
He turned the folder around.
A small yellow slip was attached to the inside cover.
The name written on it was Thomas Vale.
The date was thirty-one years old.
Below the name was a handwritten note:
RETURNED TO ENGINEERING — NOT FOR PUBLIC RELEASE.
"Who is engineering?" I asked.
Mercer shook his head.
"The department was reorganized years ago. Most of those records were transferred."
"Where?"
He studied the note again.
"There's one possibility."
He took a sheet of paper from his desk and wrote down another address.
It was not a government building.
It was a storage facility on the edge of town.
"Some of the old engineering records were moved there during the renovation," he said. "But I can't guarantee anything remains."
I folded the address and put it in my pocket.
"Thank you."
As I turned to leave, Mercer spoke again.
"One more thing."
I stopped.
"Be careful with that chamber."
"Why?"
He glanced at the photograph.
"Because the last time someone requested the Briar Glen survey, it wasn't a property owner."
"Who was it?"
He hesitated.
"Denise Vale."
I felt the room tilt slightly.
"When?"
"About three months ago."
I stared at him.
"Did she get the file?"
"No. She said she was looking for a copy of the original drainage plan. When we couldn't locate it, she left."
"Did she say why she needed it?"
Mercer shook his head.
"She only said it was a family matter."
By the time I returned home, the sun was beginning to sink behind the houses.
My driveway was empty.
The pool sat in the backyard, its dark concrete walls casting long shadows across the floor. The metal plate remained where it had been since the first day, sealed beneath a thin layer of dust.
I walked toward it.
Something had changed.
A narrow line of fresh scratches crossed the surface of the plate.
I crouched down and ran my fingers near the edge.
Someone had tried to pry it open.
Not long ago.
I stood quickly and looked toward the fence.
No one was there.
Then I heard a sound from behind the house.
A soft metallic click.
I turned.
The gate leading to the side yard was moving.
Someone had opened it.
"Hello?"
No answer.
I walked toward the gate, keeping my eyes on the narrow passage between the house and the fence.
A small object lay on the ground beside the latch.
It was a key.
Old, brass, and dark with age.
A strip of paper had been tied through its handle.
I bent down and untied it.
There were only five words written on the paper.
YOUR FATHER DIDN'T DIE ACCIDENTALLY.
I read the sentence again.
Then I realized something.
I had never told anyone about my father.
Not Martin.
Not Peter.
Not Evelyn Shaw.
And certainly not Denise Vale.
I stood motionless in the narrow passage, the key cold in my palm.
For the first time, I understood that the mystery beneath my pool might not have begun with the construction of Briar Glen.
It might have begun long before I bought the house.
And whoever had left that message knew something about my family that I had spent most of my life trying not to remember.
I didn't move for several minutes.
The key rested in my palm, its edges pressing into my skin. The message tied to it seemed impossible to ignore, yet every instinct told me not to believe it.
YOUR FATHER DIDN'T DIE ACCIDENTALLY.
