The little boy ran as fast as he could.

His bare feet pounded against the wet sand.

The blue towel was clutched tightly against his chest like it was the most important thing in the world.

“Dad!”

His voice carried across the dunes.

The man at the top of the wooden stairs turned around.

At first, he smiled.

Then he saw the tears.

The panic.

The way his son could barely catch his breath.

And his smile disappeared.

The boy raced up the stairs two at a time.

“Dad, I found it!”

The man hurried down several steps.

“What happened?”

The boy held out the towel with trembling hands.

“It washed back.”

The father froze.

For a moment he couldn’t speak.

Because he recognized the towel instantly.

A faded blue beach towel.

One that had disappeared years ago.

On the worst day of his life.

The boy wiped his eyes.

“I saw it in the water.”

The father’s hands shook as he unfolded the towel.

Something heavy dropped from inside.

A small metal box.

Rust-covered.

Weathered by years of saltwater.

The boy stared.

“What is it?”

The father didn’t answer.

His face had gone completely pale.

Because he knew exactly what it was.

He had buried that box himself.

Ten years earlier.

The day his wife vanished at sea.

The day everyone told him to stop searching.

The day he gave up hope.

The lock was broken.

Slowly, he opened it.

Inside were photographs.

Letters.

And a waterproof envelope.

The boy looked up.

“Mom?”

The father’s eyes filled with tears.

Written across the front of the envelope were six words.

IF YOU FIND THIS, I’M ALIVE.

The world seemed to stop.

The wind.

The waves.

Even the distant cries of seagulls.

Everything disappeared.

Because the woman everyone believed had died ten years ago had left behind a message.

And somehow…

It had just returned with the tide.
