He dusted the frame every morning.
He never moved her books.
Her unfinished project remained on her desk, with a pencil resting across an open notebook.
Friends and relatives gently encouraged him to accept that she might never return.
But Mahmoud refused.
"Until someone proves otherwise," he would say, "my daughter is alive."
Some people called his faith admirable.
Others feared that it prevented him from healing.
Mahmoud did not care.
He continued visiting the mountain whenever he could.
Sometimes he walked the marked trails.
Sometimes he sat near the stream where the wooden owl had been found.
He spoke to Layan aloud, telling her about ordinary things.
A neighbor's wedding.
A new tree planted in the garden.
A book he thought she would enjoy.
He did not know whether she could hear him.
He simply could not bear the thought of stopping.
Three years passed this way.
Then, on an otherwise unremarkable morning, everything changed.
The Cave No One Had Explored
The discovery began with a group of experienced cave explorers who were mapping a remote limestone formation several miles from the main hiking routes near Santa Catalina.
The team had no connection to Layan's disappearance.
They were interested in underground geology, particularly the network of narrow passages formed by water moving through fractured rock over thousands of years.
A recent period of heavy rain had washed loose sediment from a hillside, revealing an opening partially hidden behind shrubs.
The entrance was barely wide enough for a person to crawl through.
From outside, it looked like a shallow crack.
But when one explorer directed a flashlight inside, the beam disappeared into an unexpectedly deep passage.
The team decided to investigate.
They secured their equipment, checked their lights, and entered one at a time.
The first section was difficult.
Loose stones covered the ground. The ceiling dropped so low that they had to move on their hands and knees. In some places, they squeezed sideways between rough limestone walls.
After several minutes, the passage widened.
The explorers emerged into a sloping corridor where cool air moved steadily through the darkness.
That airflow caught their attention.
It suggested the cave was connected to other openings somewhere deeper inside the mountain.
They continued.
Their footsteps echoed strangely.
Water dripped from the ceiling.
At one point, an explorer noticed scratches on a rock wall.
They appeared too regular to have been caused by natural erosion.
Farther along, another member of the team discovered a short section of old rope.
The fibers were worn and coated with mineral deposits, but the rope seemed to have been tied deliberately around a stone projection.
Someone had been there before.
As the team descended farther, they began noticing other unexpected details.
A flattened area of ground.
Several stacked stones.
A fragment of cloth caught beneath a rock.
Then they reached a chamber with a relatively even floor.
At first, everything looked ordinary.
There were pale limestone formations along the walls and a narrow channel through which water had once flowed.
But near the far side of the chamber, one explorer noticed an unusual shadow.
It had the shape of a seated person.
He raised his flashlight.
The shadow moved.
He stopped walking.
"There's someone here."
The others gathered behind him.
At first, they thought the person might be an injured explorer.
Perhaps someone had become trapped.
Perhaps the figure had entered through another opening.
But when they approached, the young woman sitting near the wall lifted her head.
Her eyes followed the moving lights.
She was wearing a clean, faded blue shirt and dark trousers.
Her hair was neatly tied back.
Her hands rested in her lap.
She looked thin and pale, but not as severely malnourished as someone might expect after years of isolation.
Most disturbingly, she did not seem surprised to see them.
She smiled.
The expression was broad and strangely motionless.
"Hello?" one explorer called.
She gave no answer.
"Are you hurt?"
Still nothing.
The man lowered his flashlight slightly, trying not to shine it directly into her face.
"Can you tell us your name?"
For several seconds, she remained completely still.
Then she whispered something.
The explorer leaned closer.
"Layan."
He froze.
"Did you say Layan?"
The woman nodded.
Another member of the team immediately recognized the name.
He remembered news reports about a university student who had disappeared in the mountains several years earlier.
"Layan Mahmoud?"
She looked at him.
Then she nodded again.
No one spoke.
The explorers had entered an unfamiliar cave expecting to find rock formations.
Instead, they had apparently discovered a missing woman whose disappearance had remained unsolved for three years.
One of them reached for his radio.
Another crouched beside her.
"Layan, we've come to help you."
For the first time, her expression changed.
The smile faded.
Her eyes widened.
And when the explorer moved toward the passage leading out of the chamber, she grabbed his wrist.
"Please," she whispered.
He turned back.
"What's wrong?"
Her fingers tightened around his arm.
"Please don't go out there."
The others exchanged confused looks.
One explorer assumed she feared another rockfall.
Another wondered whether the cave contained an unstable passage that they had failed to notice.
But Layan was not looking toward the entrance.
She was looking behind them.
Into a darker corridor near the bottom of the chamber.
Then the sound began.
Tap.
A pause.
Tap.
The unmistakable noise of wood striking stone.
Between the taps came footsteps.
Slow and deliberate.
Layan's hands began to tremble.
And from the darkness, an elderly man appeared.
The Man With the Wooden Stick
The stranger was thin, with a deeply lined face and a beard streaked with gray.
He wore a loose, weathered garment and carried a wooden walking stick polished by years of use.
His clothes were simple but relatively clean.
He stopped when he saw the explorers.
For several seconds, he said nothing.
