Not against Jessica.
Not against David.
Against the silence.
Against the lies.
Against everyone who thought death would make her powerless.
But there was still one mystery.
The detective hadn’t told me everything.
And when he pulled me aside after David and Jessica were taken away, he lowered his voice.
“There’s something else you need to know.”
I looked at him.
“What?”
He glanced toward Lily.
“Sarah didn’t only leave evidence against them.”
He handed me another envelope.
“She left evidence against someone else.”
My heart sank.
“Who?”
The detective looked toward the hallway.
“Someone who was inside this house the night your daughter died.”
And suddenly, I realized Sarah’s warning wasn’t finished.
Not even close.
PART 4
The detective looked toward the hallway.
“Someone who was inside this house the night your daughter died.”
For several seconds, I couldn’t move.
The house seemed to become strangely quiet.
Even Lily had stopped crying.
I looked toward the hallway where family members had gathered, each face suddenly appearing unfamiliar.
“Who?” I whispered.
Detective Reynolds didn’t answer immediately.
Instead, he handed me the envelope.
It was smaller than the first one.
My name was written on it in Sarah’s handwriting.
I recognized the letters immediately.
My fingers trembled as I opened it.
Inside was a single photograph.
It showed Sarah standing in the kitchen.
She was smiling.
But behind her, reflected in the dark window, was a figure.
A man.
I couldn’t see his face.
Only his silhouette.
Underneath the photograph Sarah had written:
Mom, this is the person David never told you about.
My stomach dropped.
“Who is he?”
Detective Reynolds leaned closer.
“We believe he’s connected to the financial transfers.”
“David?”
“No.”
“Jessica?”
“No.”
“Then who?”
He pointed to the photograph.
“Your daughter’s accountant.”
I stared at him.
“Martin?”
He nodded.
Martin Blake had handled Sarah’s business accounts for almost four years.
He had been at the funeral.
He had stood near the back of the room.
He had shaken my hand.
He had even hugged me and told me Sarah was like a sister to him.
And I had believed him.
Detective Reynolds continued.
“Martin claims he left the house at 9:15 p.m. the night Sarah died.”
I looked at the photograph.
“Sarah’s death was at 10:40.”
“Exactly.”
My heart began pounding.
“So he was still here.”
“We believe so.”
“Then why wasn’t he arrested?”
“Because we haven’t been able to prove he was inside.”
I looked at the picture again.
“Sarah could.”
“That’s what we’re hoping.”
He pointed to the memory card I had found inside the piano.
“She recorded everything.”
I suddenly understood why Sarah had been so afraid.
She hadn’t been fighting one enemy.
She had been surrounded.
David.
Jessica.
Martin.
Possibly others.
And yet, somehow, she had been planning three steps ahead.
“Where is Martin now?”
The detective looked at the front window.
“He left the funeral shortly after we arrived.”
My blood ran cold.
“Did you stop him?”
“We tried.”
“And?”
“He was gone.”
I stared at the detective.
“You let him leave?”
“We didn’t have enough grounds to detain him.”
He paused.
“But we know where he lives.”
Then Lily tugged my sleeve.
“Grandma.”
I looked down.
“What is it, sweetheart?”
She pointed toward the staircase.
“Mommy said not to go upstairs.”
I froze.
“When did Mommy say that?”
“Before.”
“Before what?”
Lily frowned, trying to remember.
“Before she went to heaven.”
The detective crouched beside her.
“Lily, can you tell me what Mommy said?”
My granddaughter looked at him cautiously.
“She said…”
Her tiny voice became almost a whisper.
“Don’t let Daddy find the blue room.”
My heart stopped.
“Blue room?”
I had never heard of a blue room.
Sarah’s house had four bedrooms.
A home office.
A guest room.
A nursery.
A master bedroom.
No blue room.
I looked toward the stairs.
“Sarah never had a blue room.”
Lily pointed upstairs.
“Yes she did.”
Detective Reynolds and I exchanged a look.
“Where?”
Lily climbed out of my arms and walked toward the stairs.
She stopped at the third step.
Then she pointed to the wall.
“Behind there.”
I stared.
There was nothing unusual.
Just a framed family photograph.
Sarah.
David.
Lily.
Taken three years earlier.
I stepped closer.
The frame looked slightly crooked.
I touched it.
It moved.
I pulled it away from the wall.
Behind it was a small keypad.
My breath caught.
“This wasn’t here before.”
Detective Reynolds examined it.
“Do you know the code?”
I shook my head.
Then Lily spoke.
“Mommy said four numbers.”
“What numbers?”
She looked at me.
“Your birthday.”
I stared at the keypad.
My birthday.
I entered the four digits.
Nothing happened.
I tried Sarah’s birthday.
Nothing.
Then Lily whispered:
“Not your birthday.”
She pointed at the photograph.
“Grandma’s birthday and Mommy’s birthday.”
I looked at the keypad.
Eight digits.
I entered the combination.
There was a soft click.
The wall moved.
A narrow door opened.
Behind it was a small room painted blue.
My entire body went cold.
Sarah had hidden a room inside her own house.
A room she had never told me about.
Detective Reynolds entered first.
There was a desk.
Three computer monitors.
A filing cabinet.
Several boxes.
And photographs covering one entire wall.
Photographs of David.
Jessica.
Martin.
Bank transfers.
Documents.
Dates.
Times.
License plates.
Hotel entrances.
Restaurant receipts.
Everything.
Sarah had been investigating her own husband.
I stepped closer to the wall.
There were photographs of David meeting Jessica.
David entering hotels.
Jessica meeting Martin.
Martin carrying folders from Sarah’s office.
And then I saw something that made me physically sick.
A photograph of David standing beside Sarah’s car.
The date was two days before Sarah died.
Written beneath it:
He knows I found out.
I covered my mouth.
Detective Reynolds opened the filing cabinet.
Inside were dozens of documents.
He began photographing them.
Then he stopped.
“Barbara.”
I looked over.
He was holding a medical report.
“What’s this?”
I read it.
It was Sarah’s medical examination from three weeks before her death.
It stated that Sarah had been experiencing dizziness and headaches.
But beneath that was something else.
A toxicology consultation.
My eyes widened.
“Poison?”
Detective Reynolds looked at me.
“Not confirmed.”
“Then what?”
“Sarah suspected someone was poisoning her.”
I sat down.
The room spun.
“She told me she was tired.”
“She may have been sick.”
“From what?”
He pointed to another document.
A prescription.
Sarah had been prescribed medication for anxiety.
But the bottle found in her kitchen contained something else.
Something that could cause severe dizziness.
Something that could make a person appear intoxicated or disoriented.
Something that could make a fall look accidental.
My hands went numb.
“David.”
Detective Reynolds shook his head.
“We don’t know yet.”
Then his phone rang.
He answered.
“Reynolds.”
He listened.
His expression changed.
“What?”
He looked toward me.
“Repeat that.”
Another pause.
Then he said:
“Send the team immediately.”
He hung up.
“What happened?”
He looked at me.
“Martin Blake’s house is empty.”
My heart sank.
“He ran?”
“No.”
The detective’s voice became quieter.
“His neighbor found his front door open.”
He paused.
“And blood on the floor.”
TWO HOURS LATER
The police searched Sarah’s house from top to bottom.
Nobody was allowed to leave.
Every room was photographed.
Every drawer was opened.
Every computer was secured.
Lily stayed beside me in the living room, watching cartoons with the sound turned low.
I couldn’t stop thinking about the blue room.
Sarah had built an entire secret investigation inside her own home.
She had known she was in danger.
She had known her husband was betraying her.
She had known someone was trying to destroy her.
And still, she had continued protecting Lily.
Detective Reynolds returned around midnight.
He sat across from me.
“Martin is alive.”
I exhaled.
“Where?”
“In a hospital.”
“Was he attacked?”
“Yes.”
“By whom?”
“We don’t know.”
“What happened?”
“He was struck from behind.”
“Is he conscious?”
“No.”
I stared at him.
“Then how do we know anything?”
“We found something beside him.”
He placed a plastic evidence bag on the table.
Inside was a small silver key.
I recognized it.
It was the key to Sarah’s safety deposit box.
The same box Sarah had mentioned in the video.
My heart started pounding.
“He had the key?”
“Yes.”
“Then he knew about the evidence.”
“Apparently.”
I looked at Detective Reynolds.
“Maybe David sent someone.”
“Maybe.”
“Maybe Jessica.”
“Maybe.”
“Maybe Martin was trying to run with the evidence.”
“That’s possible too.”
He leaned forward.
“But there’s something else.”
“What?”
“We found security footage from a gas station near Martin’s house.”
He pulled out his phone.
A video began playing.
A black SUV pulled into the station.
A man got out.
Baseball cap.
Dark jacket.
Face partially hidden.
He walked toward Martin’s car.
Then the footage ended.
“Can you identify him?”
“No.”
“License plate?”
“Covered.”
I stared at the screen.
Then I noticed something.
The man walked with a slight limp.
I had seen that walk before.
My stomach tightened.
“Stop.”
Detective Reynolds paused the video.
“Go back.”
He did.
The man walked past the camera.
I stared.
“No.”
“What?”
“I know him.”
“Who?”
I swallowed.
“David’s brother.”
Detective Reynolds frowned.
“Thomas?”
I nodded.
“Thomas Mitchell.”
David’s younger brother.
The man who had been at the funeral.
The man who had cried.
The man who had hugged me and said, “Sarah was the best thing that ever happened to our family.”
I suddenly remembered something.
At the funeral, Thomas had disappeared for nearly an hour.
He said he had gone outside to make a phone call.
I had thought nothing of it.
Now I couldn’t stop thinking about it.
Detective Reynolds stood.
“Where is Thomas?”
I reached for my phone.
“I’ll call him.”
“No.”
The detective shook his head.
“Don’t.”
“Why?”
“Because if he is involved, we don’t want him to know we’re onto him.”
He took out his own phone.
“I’ll have someone locate him.”
Then Lily suddenly spoke from the couch.
“Grandma?”
I turned.
She was holding Sarah’s old stuffed rabbit.
“Mommy told me something else.”
My heart clenched.
“What did she tell you?”
“She said if Daddy gets angry…”
Lily’s eyes filled with tears.
