Chapter 1 - THE HAND BENEATH THE FLOOR

“Daddy, he says it is dark.”
Jimena Rivera’s sobbing voice barely reached Mateo over the pounding of his own heart.
His five year old daughter knelt beside the living room floor, pointing toward a darker seam between two pale wooden boards.
Three weak knocks sounded beneath them.
Mateo tightened both hands around the black iron fireplace poker.
For almost one year, he had imagined hearing his missing son everywhere.
In the hallway outside Emil’s bedroom.
Behind playground laughter.
Inside crowded stores whenever a child called for his father.
Each time, hope rose before reason destroyed it.
This was different.
Mateo pressed his ear against the floor.
The house became silent around him.
No traffic.
No heating system.
No movement from the kitchen.
Then came another knock.
Directly beneath his cheek.
His older sister Rebecca rushed into the living room and grabbed his forearm.
“Stop. There is nothing under there.”
Her fingers dug into his skin.
Mateo looked up at her.
Rebecca stood perfectly dressed in a cream blouse and tailored trousers. Her shoulder length dark hair remained smooth. Understated gold jewelry caught the warm afternoon light.
Only her face had changed.
She did not look confused by Jimena’s claim.
She looked terrified that Mateo believed it.
He pulled his arm free without striking or shoving her.
Then he dragged the pale rug completely aside.
The glass coffee table scraped across the floor.
Near the wall, one section of wood was darker than the rest. The boards had been replaced recently and did not align perfectly with the original flooring.
Three months after Emil disappeared, Rebecca had renovated this room.
She told everyone the old boards creaked.
Mateo moved closer.
Something small protruded through the narrow seam.
A dirty fingernail.
Jimena covered her mouth.
Mateo slowly turned toward his sister.
“What did you do?”
Rebecca’s coffee cup slipped from her hand.
It shattered across the floor.
She fell onto both knees.
“I never meant for him to stay this long.”
The words removed the last fragment of doubt.
Mateo pulled Jimena safely behind him.
“Stay near the sofa.”
She obeyed, although every part of her wanted to remain close to the floor.
Mateo forced the pointed end of the poker beneath the weakest seam.
Rebecca grabbed his arm again.
“You cannot break that.”
“My son is underneath it.”
“You will hurt him.”
“Then tell me where the latch is.”
She stared at him.
“Rebecca.”
Her eyes moved toward the decorative fireplace.
Mateo saw a brass key resting inside the ash bucket.
He seized it.
A narrow metal opening had been concealed beneath the edge of the rug. The key turned halfway before stopping.
Something inside the mechanism had been locked from below.
Mateo returned to the loose boards.
He drove the poker into the seam, keeping the point angled upward and away from the space beneath.
The first board cracked.
Cold air escaped from the darkness.
It smelled of damp concrete, old wood, and something medicinal.
Mateo pulled the broken plank aside with both hands.
A small dirty hand immediately reached through the opening and wrapped around his wrist.
Mateo stopped breathing.
“Dad.”
The voice was weak.
Almost unrecognizable.
“Is that really you?”
Mateo dropped the poker.
He gripped the child’s hand with both of his.
“Emil.”
A frightened brown eye appeared beneath the opening.
Dark hair covered part of a thin face.
His son was alive.
Mateo’s body shook with such force that he nearly lost his balance.
“I am here, buddy.”
“Do not leave.”
“I am not going anywhere.”
Jimena crawled toward the opening.
“Emil?”
The eye moved toward her voice.
“Mena.”
She began crying harder.
Only Emil had shortened her name that way.
Mateo widened the opening carefully, pulling loose fragments upward instead of striking again.
He could see the outline of a narrow room beneath the floor.
A thin mattress rested against one wall.
Medicine bottles stood beside a metal cup.
A ventilation pipe ran toward the basement.
Emil’s plastic dinosaur lay beneath the opening.
Jimena had carried that toy everywhere after her brother disappeared.
It vanished from her bedroom during the week of the search.
Rebecca told them grief had made Jimena misplace it.
Laura Rivera entered through the front door just as Mateo removed another board.
She had been delayed at work and arrived expecting cinnamon coffee and an uncomfortable family visit.
Instead, she saw her daughter kneeling beside a broken floor and her husband holding a child’s hand through the darkness.
Laura’s purse fell from her shoulder.
“Mateo?”
He looked at his wife.
His face collapsed.
“It is Emil.”
Laura stumbled toward the opening.
Rebecca backed toward the staircase.
One hand moved behind her body.
She was reaching for her smartphone.
Mateo saw her.
“Put it down.”
“I need to call someone.”
“You need to tell me how to open this room.”
“I cannot.”
“Why?”
Her eyes filled with tears.
“Because he will know.”
“Who?”
Rebecca looked toward the basement ventilation grate.
A faint electronic tone sounded beneath the floor.
Emil’s fingers tightened around Mateo’s wrist.
“He knows you found us.”
“Us?”
Mateo looked deeper into the darkness.
A second backpack rested beyond the mattress.
It was purple and covered with silver stars.
It did not belong to Emil.
Another knock came from farther beneath the house.
Three slow taps.
Then a child’s frightened whisper rose through the opening.
