She believed she knew everything about him.
Apparently, she did not.
Margaret immediately called Elizabeth.
Her friend arrived twenty minutes later.
When Margaret showed her the letter, Elizabeth read it twice.
"Have you ever heard of Catherine?"
Margaret shook her head.
"Never."
"Could she have been someone Robert worked with?"
"Perhaps."
Elizabeth examined the photograph.
"Look at the little girl."
Margaret leaned closer.
The child had dark curly hair and a small birthmark near her left eyebrow.
Robert was smiling at her.
It was not the polite smile he gave strangers.
It was the warm, affectionate smile Margaret remembered from their happiest years.
"Who is she?" Elizabeth whispered.
Margaret turned the photograph over again.
"I don't know."
Elizabeth picked up the brass key.
"There must be something connected to this."
Margaret looked at the letter.
At the bottom was an address.
An old building on the east side of town.
She recognized the street.
It was near the neighborhood where Robert had grown up.
"I think we should go there," Margaret said.
Elizabeth hesitated.
"Are you sure?"
Margaret nodded.
"If Robert left something unfinished, I want to understand why."
The address belonged to a small storage building.
It was older than most of the surrounding properties. The paint was peeling, and the windows were covered with dust.
A caretaker greeted them at the entrance.
When Margaret showed him the letter, he studied her face.
"You're Robert's wife?"
"Yes."
The old man smiled sadly.
"I wondered when you would come."
Margaret looked at him.
"You knew my husband?"
"Not well. But I knew what he was trying to protect."
He led them down a narrow hallway and stopped in front of a metal door.
There was a small number engraved above the handle.
217.
Margaret took the brass key from her handbag.
It fit perfectly.
Inside was a collection of boxes, old photographs, documents, and carefully preserved children's drawings.
On a wooden table sat a second envelope.
This one was addressed to Margaret.
She opened it.
My dearest Margaret,
If you're reading this, then I have waited long enough for you to discover something I never found the courage to explain.
Before I met you, I made a promise to a woman who had nowhere else to turn. Her name was Catherine Bennett.
She had a daughter named Lily.
Lily was not my child, but I became someone important in her life during a difficult period.
I helped Catherine find work, paid for Lily's education when necessary, and promised that she would always have a safe place to return to.
I never told you because Catherine eventually moved away, and I believed the matter had been resolved.
But I was wrong.
Margaret paused.
Her eyes moved down the page.
There is something else. Lily grew up believing that I abandoned her. I tried to contact her several times, but circumstances prevented us from meeting again.
If you can find her, please tell her that I never forgot her.
And tell her that the promise still stands.
With all my love,
Robert.
Margaret slowly lowered the letter.
Elizabeth placed a hand on her shoulder.
"Margaret..."
She could barely speak.
"Why would he hide something like this?"
Elizabeth looked at the photographs.
"Maybe he was trying to protect you from something."
Margaret shook her head.
"I don't think I wanted to be protected from the truth."
She looked at the little girl in the photograph.
For the first time, she wondered whether Robert had spent his final years carrying a regret he had never shared with her.
The documents revealed that Catherine Bennett had died eight years earlier.
Her daughter, Lily, was now thirty-four.
She lived in another state and worked as a nurse.
Margaret stared at the information.
A nurse.
The same profession Robert had once admired because, as he frequently said, nurses were people who spent their lives caring for strangers.
There was a phone number in the file.
Margaret hesitated.
What could she possibly say?
Hello, I'm the wife of a man who once promised to help your mother. He died years ago, and I have only just discovered that you exist.
It sounded impossible.
Elizabeth gently took her hand.
"You don't have to explain everything immediately. Just introduce yourself."
Margaret dialed.
The phone rang four times.
Then a woman's voice answered.
"Hello?"
Margaret swallowed.
"Is this Lily Bennett?"
"Yes. Who is this?"
"My name is Margaret Collins. I believe you may have known my husband, Robert."
There was silence.
Then Lily asked a question Margaret would never forget.
"Is he still alive?"
Margaret closed her eyes.
"No, sweetheart. I'm afraid he passed away twelve years ago."
Another silence.
Then Lily whispered:
"I thought he was dead."
