The first thing I saw after six years overseas was my sixty-eight-year-old mother on her knees, scrubbing red wine from the marble floor of the house I had bought for her. My older brother Derek stood above her in a bathrobe while his wife sipped champagne and complained that Mom was “smearing” the stain. Then I saw the plastic badge pinned to her gray uniform: MARGARET — HOUSEKEEPING.

For one second, I thought she had finally decided to leave.

Her arms tightened around me.

I felt her cheek against mine.

Then one of her hands slipped beneath the edge of my coat.

Something small dropped into my pocket.

Cold metal.

Mom pulled away just enough for her lips to reach my ear.

“Don’t let Derek see the key.”

My entire body froze.

She looked directly into my eyes.

The fear in hers was unmistakable.

Then she whispered six words.

“If he finds out, he’ll kill me.”

Derek stepped toward us.

“What did she say?”

My heart was hammering hard enough to hurt.

I forced my mouth into something close to a smile.

“She said she’s happy I came home.”

Mom stared at me.

I squeezed her hand once.

Then I released it.

Every instinct I had screamed not to leave her there.

But another part of me understood what Mom was doing.

She had waited six years.

She had hidden something.

And whatever she had just put into my pocket mattered enough that she believed Derek might hurt her over it.

If I forced the situation now, I might destroy the only advantage she had managed to keep.

I picked up my suitcase.

Derek’s shoulders relaxed slightly.

That almost made me turn around.

“Tomorrow,” he said.

I looked at him.

“Yes.”

He smiled again.

“Tomorrow.”

I walked out through the front door.

I did not look back until I reached my rental car.

Derek stood behind the tall front window.

Watching me.

I put the suitcase in the trunk,

got into the driver’s seat, and locked the doors.

Only then did I reach into my coat pocket.

The object was old brass.

Heavy for its size.

At first, I thought it might be a cabinet key.

Then I saw the square opening at the end.

My hand tightened around it.

I had held that key hundreds of times as a child.

Every Sunday evening, Dad used it to wind the walnut clock that had stood on our mantel when Derek and I were growing up.

After Dad died, Mom continued the ritual.

When she moved into the Georgian house, the clock had gone with her.

The clock that was now missing.

The one piece of furniture I had noticed immediately because its empty space felt wrong.

I stared through the windshield at the house.

Derek had proudly shown me the deed.

He wanted me to see it.

He wanted me angry about it.

He wanted the argument centered on whether Mom had transferred the property.

But Mom had risked slipping me the winding key to something Derek had removed from the room.

Which meant the deed was probably not the secret she was trying to protect.

It was only the secret Derek wanted me to see.
