If the old man's information was accurate, the chamber beneath my pool had never been a simple water storage structure.
It had been part of a much larger system.
I was studying the map when someone knocked on the front door.
Three slow knocks.
I approached cautiously and looked through the peephole.
Denise Vale stood on the porch.
I opened the door but kept the security chain fastened.
"What do you want?"
She looked tired. Her hair was pulled back, and her face was pale.
"We need to talk."
"About what?"
"Your father."
I felt my hand tighten around the edge of the door.
"How do you know about my father?"
"Because he came to see mine."
"When?"
"Before he died."
I stared at her.
"Why didn't you tell me?"
"Because I thought the past was finished."
"Apparently it isn't."
She looked past me into the house.
"Have you found the map?"
I didn't move.
"What map?"
"The original drainage survey."
I felt my pulse quicken.
"Why do you want it?"
"Because if you open that chamber, you'll make the same mistake your father made."
"What mistake?"
She looked directly into my eyes.
"He trusted the wrong person."
"Who?"
For the first time, I saw genuine fear in her expression.
"Martin Cole."
I shook my head.
"Martin told me about Daniel Ruiz. He told me about the falsified report."
"Then he told you what he wanted you to believe."
"Why would he lie?"
"Because he knows what happened to your father."
I felt the air leave my lungs.
"What happened to my father?"
Denise looked down at the porch.
"I can't tell you here."
"Then where?"
"Tomorrow night. The old pumping station."
I stared at her.
"Why should I meet you there?"
"Because there are things beneath that land that were never meant to be found."
"That isn't an answer."
"No," she said. "It isn't."
She reached into her coat and removed a small photograph.
She slid it through the narrow opening in the door.
It showed my father standing beside a young woman.
The woman was Denise.
She looked no older than eighteen.
On the back of the photograph, someone had written a date.
October 6, 1994.
Beneath it were five words.
THE NIGHT ROBERT HALE DISAPPEARED.
I looked up.
Denise was already walking away.
"Wait!"
She stopped at the end of the porch.
"Did my father disappear?"
She didn't turn around.
"That's what the police report says."
"Then why did my mother tell me he died in a car accident?"
Denise stood very still.
Finally, she looked over her shoulder.
"Because your mother was told to say that."
Then she walked toward her house and closed the door.
I remained on the porch, holding the photograph.
The date was impossible.
My father had supposedly died in 2004.
But the photograph was dated 1994.
And Denise had just told me he had disappeared.
For the first time, I wondered whether the accident that had shaped my childhood had ever happened at all.
I didn't sleep that night.
Denise's photograph lay on the kitchen table beside my father's notebook. I had placed a glass paperweight over it, as if a little pressure could keep the past from moving any further into my life.
October 6, 1994.
The date had been written in dark blue ink. My father stood beside Denise, one hand resting on the shoulder of a man I recognized from the photograph Martin had shown me.
Thomas Vale.
They were standing in front of a concrete building with a rusted metal door. Behind them, a narrow drainage channel disappeared into the ground.
My father looked younger than I remembered him from my childhood photographs. His hair was darker, his face thinner, but the expression was unmistakable. He was smiling.
I hadn't seen that smile in years.
On the back of the photograph, beneath the date, someone had added a second line in smaller handwriting.
If Robert returns, do not let him enter alone.
I couldn't tell who had written it.
At seven in the morning, I called my mother again.
This time, she answered immediately.
"Please don't call me about this anymore," she said.
"Mom, I need you to listen."
"I've already told you what I know."
"No. You've told me what you want me to believe."
She was quiet.
I looked at the photograph.
"Was Dad alive in October 1994?"
A long pause followed.
"Yes."
The answer was so simple that it took me a moment to understand it.
