The screen went black.
Harper stared at the laptop, hoping Daniel Pierce’s face would reappear.
Nothing.
Only her own reflection stared back.
Detective Lena Ortiz slowly closed the computer.
“Our forensic team believes the missing portion of the video can be recovered.”
“How long?”
“A day.”
Harper shook her head.
“We don’t have a day.”
Ortiz couldn’t argue.
For the first time since the investigation began, she agreed.
Someone was accelerating their plan.
Nathan spent the night pacing the library.
Every warning Harper had given him echoed in his mind.
The riding accident.
The poisoned butter.
The missing estate file.
Daniel’s disappearance.
He wanted to believe there was a reasonable explanation.
Instead, every answer created another question.
Evelyn entered quietly carrying two cups of tea.
“You should get some rest.”
Nathan accepted the cup but didn’t drink it.
“When did you first meet Daniel Pierce?”
Evelyn looked surprised.
“Years ago, I suppose.”
“You told me you barely remembered him.”
“I didn’t think it mattered.”
“It matters now.”
She sat across from him.
“You’re beginning to doubt me.”
Nathan remained silent.
“I understand why,” she continued. “Harper has been frightened, and fear has a way of spreading.”
Nathan looked into her eyes.
“Did you ever know Charles Mercer’s daughter?”
A long pause followed.
“Emily?”
“Yes.”
“I cared about her.”
Nathan leaned forward.
“Did she ever tell anyone she was afraid of you?”
For the first time, Evelyn didn’t answer immediately.
“When people grieve,” she said softly, “they often remember conversations differently.”
Nathan noticed she had answered a different question.
The next morning, Harper met Zoe outside the public library.
“I keep thinking about my mom’s note.”
“The person you’re looking for isn’t the one everyone fears.”
Zoe folded her arms.
“So who is it?”
“I don’t know.”
“But what if we’ve been chasing the wrong person?”
Before Zoe could answer, Harper’s phone vibrated.
It was Detective Ortiz.
“I need you to leave the estate.”
Harper’s stomach tightened.
“Why?”
“We found evidence someone has been inside your bedroom repeatedly.”
“I already knew that.”
“This is different.”
Ortiz’s voice became firmer.
“We found fingerprints that don’t belong to anyone living in the house.”
Harper froze.
“So someone else has been coming inside.”
“Yes.”
“And until we identify that person…”
“I don’t want you staying there alone.”
Harper returned home only long enough to pack a small overnight bag.
Mrs. Alvarez met her at the foot of the staircase.
“You’re leaving?”
“Just for a couple of days.”
The older woman’s eyes filled with concern.
“Your mother always said this house could keep secrets.”
Harper looked at her.
“What did she mean?”
Mrs. Alvarez hesitated.
“There’s an old service passage behind the west wing.”
“I’ve never heard of it.”
“Most people haven’t.”
“It was built when the house was constructed.”
“Where does it go?”
“Almost everywhere.”
Harper’s pulse quickened.
“Can you show me?”
Mrs. Alvarez nodded.
She led Harper to the old butler’s pantry beside the dining room.
Behind a row of shelves, she pressed against an ornate wooden molding.
A hidden door clicked open.
Cold air drifted from the darkness beyond.
A narrow brick corridor stretched beneath the house.
Harper switched on her flashlight.
The walls were lined with dust.
Cobwebs hung from the ceiling.
Yet one thing immediately stood out.
Footprints.
Fresh ones.
Someone had been using the passage.
Recently.
The corridor twisted beneath the estate before ending behind a concealed panel inside Rebecca’s old study.
Harper slowly pushed it open.
The room appeared empty.
Then she noticed something on the desk.
A single sheet of paper.
It hadn’t been there the day before.
Across the top, in Rebecca’s unmistakable handwriting, were the words:
If you found the passage, you’re close.
Harper’s hands trembled.
The note continued.
There are places in this house that even your father doesn’t know about. If anyone ever tells you I died because I was sick, ask them to prove it. Truth leaves evidence. Lies erase it.
Before Harper could read further, footsteps echoed through the study.
Not from the hallway.
From inside the hidden passage.
Someone else was coming.
Harper switched off her flashlight and slipped behind a tall bookcase.
The concealed panel opened slowly.
A figure stepped into the study.
Dressed in black.
Face hidden beneath a hood.
The intruder walked directly to Rebecca’s desk.
Opened the top drawer.
Removed a sealed envelope.
Then turned toward the hidden passage again.
As the figure reached the doorway, a small object slipped from a coat pocket and landed on the hardwood floor.
The intruder disappeared into the darkness without noticing.
Harper waited until the footsteps faded.
Only then did she emerge from hiding.
She picked up the object.
It was a polished silver cuff link.
Engraved with an ornate letter.
A.
The same letter she had seen on the signet ring worn by the unidentified man in the old charity photograph.
Her pulse raced.
For the first time, Harper had physical evidence that someone besides Evelyn was moving through the house in secret.
And whoever that person was…
They knew every hidden passage in the Calloway estate.
