Chapter 8 - The Key Inside the Cake

The destroyed birthday cake had been removed from the Mercer estate before police secured the property.
No one knew who had taken it.
The catering company denied responsibility. The cleaning staff said Adrian had ordered all food waste loaded into a private disposal van. Security footage from the service entrance had been erased during the hospital blackout.
Daniel returned to the estate with Detective Ross, two forensic technicians, and a police escort.
The house looked like a battlefield preserved beneath chandeliers.
Broken crystal still covered the ballroom floor. Blue frosting stained the carpet. Half-deflated balloons drifted near the ceiling.
Near the courtyard doors, two plastic stools remained beside the trash bins.
Daniel stopped.
The sight affected him more than the shattered banquet.
He imagined Thomas and Mary sitting there while his wealthy guests laughed inside.
He remembered passing his mother near the doors that evening.
Vivian had been smiling.
He had asked whether Clara’s parents had arrived.
She had said they were resting after the drive.
Daniel had accepted the answer because believing his mother was easier than noticing the truth.
Ross watched him.
“Where was the cake?”
He pointed.
“Forensics found traces of metallic dust near the cake stand,” she said. “Possibly from a key or internal support.”
Daniel examined the ruined floor.
A small blue handprint marked the edge of the carpet.
“Leo touched the cake before the party?”
“He wanted to see the decorations.”
Daniel called his son.
Leo answered from the hospital under Mary’s supervision.
“Did you see anything inside your cake?”
“No.”
“Think carefully.”
“There was a castle on top.”
“Did Grandma put something in it?”
Leo went quiet.
“Grandma told me not to touch the silver tower.”
Daniel looked toward Ross.
“What silver tower?”
“The middle one. She said it was expensive.”
“What happened to it?”
“Uncle Adrian took it after you broke the table.”
“Where did he go?”
“Into Grandpa’s study.”
Richard Mercer’s study had remained locked since his death. Vivian kept the only known key.
Daniel led Ross upstairs.
The study door stood open.
Inside, shelves had been emptied. Drawers hung from the desk. A portrait of Richard Mercer had been removed from the wall, revealing a steel safe.
The safe door was also open.
Nothing remained inside except a circular indentation in the velvet lining.
Ross photographed it.
“What was stored here?”
“I didn’t know the safe existed.”
Daniel approached the portrait leaning against the wall.
His father looked young and confident, one hand resting on Daniel’s shoulder. Adrian stood on the other side. Vivian sat in front of them.
Something about the image felt wrong.
Daniel lifted the frame.
The backing had been cut recently.
Inside was an envelope.
It bore his name.
DANIEL, WHEN SHE FINDS THE KEY, DO NOT LET HER OPEN THE GARDEN.
The handwriting belonged to his father.
Daniel unfolded the letter.
Son,
If you are reading this, Vivian has recovered the access key.
The public record states that Orison’s research ended in the fire. That is false.
The primary archive was moved beneath the Mercer estate before the investigation began. We called it the Garden because Vivian believed human behavior could be cultivated, corrected, and harvested.
I helped build it.
I also came to understand what she intended to do.
There are twelve viable bloodlines connected to the original program. Clara belongs to the seventh. Her daughter may represent the twelfth.
The Garden can only be opened by three elements:
The silver access key.
The biometric signature of Subject Seven.
And the living neural response of Subject Twelve.
If Vivian possesses all three, she can activate the archive.
Do not trust Adrian.
Daniel stopped reading.
Ross looked over his shoulder.
“Your father knew Clara.”
“He knew what she was.”
“Continue.”
Daniel read the last lines.
I tried to stop Vivian once.
That is why I will not survive the lake.
The portrait slipped from Daniel’s hand.
“My father’s boating accident was not an accident.”
Ross took the letter.
A sound came from behind the bookshelves.
Both officers raised their weapons.
Daniel moved toward the noise.
A narrow panel stood slightly open.
Behind it, a staircase descended into darkness.
Ross switched on her flashlight.
“Was this here when you were a child?”
“I never knew.”
They descended.
The staircase led beneath the house to a concrete corridor. Electrical cables ran along the ceiling. The air smelled of dust and disinfectant.
At the end stood a circular steel door.
Three overlapping rings were engraved into its surface.
The Garden.
Beside the door, a control panel displayed two illuminated indicators.
SUBJECT 7: VERIFIED.
ACCESS KEY: VERIFIED.
The third indicator remained dark.
SUBJECT 12: PENDING.
Daniel’s phone rang.
Dr. Ortiz was shouting.
“Mr. Mercer, Sophie is missing.”
Daniel stared at the steel door.
“How?”
“Someone triggered the fire alarm. A woman in surgical clothing removed her from the room.”
“Was it Clara?”
“We don’t know.”
The third indicator turned green.
SUBJECT 12: VERIFIED.
Locks began releasing inside the door.
May you like
Ross raised her weapon.
The Garden opened.
