Chapter 6 - The Signature Nobody Could Explain
My grandmother’s name was glowing on my phone.
Teresa Landa.
I couldn't move.
The screen continued vibrating in my hand.
My mother stared at it as if it were a loaded weapon.
Mateo stepped toward me.
“Don't answer.”
“Why?”
“Because whoever is calling wants to know whether you found the key.”
“But the caller ID says Teresa.”
“Caller ID can be manipulated.”
The phone stopped.
Silence.
Then it rang again.
Same name.
Same number.
I looked at my mother.
“You said Grandma was poisoned.”
“Yes.”
“You said she died nine days ago.”
“Yes.”
“So why is her phone calling me?”
My mother shook her head.
“I don't know.”
Mateo reached for the phone.
I pulled it away.
“No.”
“Valeria.”
“I need to hear it.”
“What if it's a trap?”
“Then I'll know.”
I answered.
“Hello?”
Nothing.
Only static.
Then a faint sound.
Three soft knocks.
My grandmother used to knock exactly three times on my bedroom door when I was a child.
Always three.
Never two.
Never four.
My heart began pounding.
“Grandma?”
Static.
Then a woman's voice.
Weak.
Breathing heavily.
“Valeria…”
I almost dropped the phone.
“Who is this?”
The voice whispered again.
“Don't trust…”
The line crackled.
“Who?”
“...the…”
A burst of static.
Then silence.
The call ended.
I stared at the screen.
My mother was crying.
Mateo looked furious.
“What did she say?”
I repeated the words.
“Don't trust…”
Then I stopped.
I remembered something.
The voice had sounded exactly like my grandmother.
Not similar.
Exactly.
The same low tone.
The same slight rasp at the end of certain words.
The same pause before saying my name.
My grandmother had been dead nine days.
Unless the recording had been made before she died.
I looked at Mateo.
“Could you record her voice?”
He didn't answer.
“Mateo.”
“Yes.”
“When?”
“Before she died.”
“Why?”
“Because she asked me to.”
My mother looked at him.
“You still have it?”
He nodded.
“Where?”
“In a secure archive.”
“Can I hear it?”
He hesitated.
Then handed me the memory card he'd shown me earlier.
“Everything you need is on this.”
I stared at it.
“You said it contained her last meeting with my father.”
“It contains more than that.”
I inserted the card into my laptop.
A folder appeared.
TERESA — FINAL
Inside were seven audio files.
The first was dated three months before her death.
The second two months.
The third six weeks.
The fourth one month.
The fifth fourteen days.
The sixth three days.
The seventh had no date.
I opened the sixth.
My grandmother's voice filled the kitchen.
“If you're hearing this, Valeria, something has gone wrong.”
My chest tightened.
Her voice continued.
“I don't know whether you'll hear this while I'm alive or after I'm gone.”
I looked at my mother.
She covered her mouth.
Teresa continued.
“Your father believes money is the only thing that matters.”
A pause.
“He is wrong.”
Another pause.
“What matters is evidence.”
The recording crackled.
Then I heard another voice.
My father's.
“You're making a mistake, Mom.”
I froze.
My grandmother answered.
“No, Sergio. You made the mistake three years ago.”
My father's voice became sharper.
“You don't understand what will happen if you expose me.”
“I understand exactly what will happen.”
“You'll destroy this family.”
“You destroyed it when you stole from me.”
Silence.
Then my father said something that made my blood run cold.
“You don't even know what Valeria does.”
My grandmother answered immediately.
“I know exactly what she does.”
I looked at my mother.
She stared at the floor.
My father's voice returned.
“She thinks she's helping people.”
“She is.”
“She doesn't know what she's involved in.”
“Neither do you.”
The recording stopped.
I stared at the screen.
“What does my father mean?”
Mateo said nothing.
I turned toward him.
“What do I do?”
He looked at me.
“You work in forensic document examination and financial fraud analysis.”
My mother closed her eyes.
I felt suddenly exposed.
“You knew.”
Mateo nodded.
“Your grandmother told me.”
I looked at my mother.
“You knew too?”
She nodded.
“But I never understood exactly what you did.”
I laughed bitterly.
“For years, I told you I worked in an office.”
“You did.”
“You made fun of my job.”
“I didn't know what it was.”
“You never asked.”
My mother looked ashamed.
I had spent years keeping my professional life private.
Not because I was ashamed.
Because every time I told my parents something important, they turned it into a competition.
When I became certified in forensic document examination, my father said it was a hobby.
When I began working on financial fraud cases, my mother called it “paperwork.”
When I started consulting for attorneys and investigators, they assumed I was an assistant.
I had let them believe it.
My grandmother was the only person who knew.
And now I understood why.
She had known exactly what I was capable of seeing.
I replayed the recording.
This time, I focused on the background.
There was a faint ticking sound.
Then a door closing.
Then my father's voice.
“Where did you get that document?”
My grandmother answered:
“From the person you thought you had paid.”
My father's breathing changed.
“Who?”
“I won't tell you.”
The recording ended.
I looked at Mateo.
“Who was he talking about?”
“I don't know.”
“You're lying.”
He didn't react.
I opened the next file.
The date was three days before Teresa died.
My grandmother's voice was quieter.
“If you're hearing this, I failed to convince everyone.”
There was a long pause.
“I need you to understand something.”
A chair moved.
Then she continued.
“The will is not the real danger.”
My skin prickled.
“The money is a distraction.”
I leaned closer to the speaker.
“The real danger is the document they believe doesn't exist.”
The recording stopped.
I stared at the screen.
“What document?”
Mateo looked at me.
“The amendment.”
I remembered what he had said.
Three days before her death.
My grandmother had changed something.
“What did she change?”
He looked at my mother.
My mother shook her head.
“Tell her.”
“I can't.”
“Why?”
“Because Teresa didn't trust me with the details.”
I stood.
“Then who does?”
Neither answered.
I opened the seventh file.
No date.
No title.
Just a string of numbers.
The audio began.
At first, there was only breathing.
Then Teresa spoke.
“Valeria, if you're listening to this, you have already found the key.”
I looked at my hand.
The silver key felt suddenly heavy.
“The key opens a safe.”
My heart raced.
“Not a bank safe.”
A pause.
“A room.”
I glanced at Mateo.
He knew.
“You must go there alone.”
My grandmother continued.
“Do not take your father.”
A pause.
“Do not take your mother.”
My mother's eyes filled with tears.
“And do not trust the man who claims he protected me.”
Mateo went completely still.
The recording continued.
“Because he was the reason I needed protection in the first place.”
The audio ended.
Nobody spoke.
I slowly turned toward Mateo.
He didn't move.
“Was she talking about you?”
“No.”
“You expect me to believe that?”
“I don't know who she meant.”
“You were the man protecting her.”
“Yes.”
“And she said not to trust the man who claimed he protected her.”
“Yes.”
“So why shouldn't I think it's you?”
He looked at me.
“Because if I wanted you dead, I wouldn't have brought you here.”
My mother whispered, “Enough.”
I ignored her.
“Where is the room?”
Mateo stared at me.
“You're not ready.”
“I'll decide that.”
He sighed.
“The key opens a private storage room beneath the old Landa warehouse.”
My heart stopped.
“Which warehouse?”
“The one your grandmother supposedly sold three years ago.”
I remembered the company records.
One warehouse had been listed as inactive.
But my grandmother had continued paying taxes on it.
I had assumed it was an accounting error.
Now I knew better.
“Why did she keep it?”
“Because that's where she hid the evidence.”
“What evidence?”
“Everything.”
I grabbed my coat.
My mother stood.
“You can't go there.”
“Why?”
“Because Sergio knows about it.”
“Then I need to go.”
“He may be waiting.”
“I know.”
Mateo shook his head.
“Not tonight.”
I looked at him.
“Why?”
“Because someone has been monitoring the warehouse.”
“Who?”
“I don't know.”
“Then how do you know?”
He didn't answer.
I walked toward the door.
My mother grabbed my arm.
“Valeria, please.”
I turned.
“I spent my entire life believing you and Dad simply didn't understand me.”
She started crying.
“I thought you were embarrassed by my work.”
“I wasn't.”
“You were.”
“I was afraid.”
“Of me?”
“Of what your father would do if he discovered how good you were at finding things.”
That stopped me.
“How good?”
My mother looked at me.
“Good enough to destroy him.”
I left the house.
Mateo followed.
“You shouldn't go alone.”
“I won't.”
He frowned.
“Who is coming with you?”
I looked at him.
“You.”
He stared at me for a moment.
Then nodded.
We drove separately.
The warehouse stood in an industrial district on the edge of the city.
It looked abandoned.
No lights.
No security guards.
No vehicles.
I parked across the street.
Mateo stopped beside me.
“Stay here.”
“No.”
“Valeria.”
“You've lied to me enough.”
He looked at the building.
“I wasn't lying.”
“You withheld information.”
“That was different.”
“It's the same thing.”
We crossed the street.
The main gate was chained.
Mateo produced a key.
I stared at him.
“You had access.”
“Yes.”
“Of course.”
He unlocked the chain.
The warehouse smelled like dust and oil.
We entered.
My flashlight swept across rows of old shelving.
At the back was a metal door.
I took out the silver key.
There was no keyhole.
Instead, there was a small black panel.
Mateo stepped back.
“Put it there.”
I inserted the key.
A light turned green.
The lock clicked.
I slowly pulled the door open.
Inside was a small room.
One desk.
One chair.
One metal cabinet.
And dozens of sealed boxes.
I stepped inside.
A label on the nearest box caught my eye.
AUGUST 14 — ORIGINALS
I opened it.
Inside were documents.
Medical reports.
Bank statements.
Property deeds.
Photographs.
And one handwritten letter.
I recognized my grandmother's handwriting immediately.
The original letter.
I unfolded it.
The first sentence read:
My son Sergio has never been entitled to my fortune.
I exhaled.
Then I read the next line.
But that is not why I am leaving everything to Valeria.
I turned the page.
There was another paragraph.
My hands began trembling.
I am leaving it to her because she is the only person in this family who can uncover what happened three years ago.
Three years.
The missing three years.
I kept reading.
Then I reached the final paragraph.
If Valeria finds this letter, she must look beneath the floor of the warehouse.
I looked down.
Mateo's face changed.
“Don't.”
I stepped backward.
“Why?”
He stared at the floor.
“Because I already looked there.”
A metallic sound came from beneath us.
One of the floor panels shifted.
May you like
Then another.
And from underneath the warehouse floor came the unmistakable sound of a phone ringing.
