He had never mentioned the Mustang.
Never.
Marcus spread the photographs across the workbench.
The discovery transformed the car from a restoration project into something else.
Something personal.
Something connected to his family.
And suddenly Evelyn's warning seemed less ridiculous.
The Mustang really was going to cause him trouble.
Marcus spent the entire night reading the letters.
They had been written more than thirty years earlier.
Most were between his father, David Reed, and a man named Samuel Walker.
Samuel had owned the Mustang.
According to the letters, David and Samuel had been close friends.
They had worked together at an auto shop when they were young.
They had also been involved in something Marcus had never heard about.
Samuel had discovered financial misconduct at the company where they worked.
Money was disappearing.
Invoices were being falsified.
Parts were being sold illegally.
At first, Samuel thought it was simply a small group of dishonest employees.
Then he discovered that the problem went much deeper.
Someone in management was involved.
Samuel had gathered evidence.
David had helped him.
But before they could report everything, Samuel was threatened.
The letters became increasingly worried.
One letter contained a warning:
"They know I have the records."
Another said:
"David says we should go to the authorities."
Then came the final letter.
It was short.
"If I disappear, the evidence is in the car. Do not trust anyone who asks about it."
Marcus stared at the words.
His father had never told him any of this.
Not once.
He searched the rest of the box.
There was no evidence.
No documents proving wrongdoing.
Only photographs, letters, and the brass key.
Marcus looked at the key.
It was tiny.
Possibly for a lockbox.
He searched the Mustang.
Nothing.
Then he noticed a small compartment behind the passenger seat.
The key fit.
The compartment opened.
Inside was an envelope.
Marcus slowly removed it.
His name was written across the front.
Not his father's name.
His.
Marcus.
His hands became cold.
He opened it.
Inside was a letter from his father.
Marcus immediately recognized the handwriting.
His father had written:
"Marcus, if you're reading this, then you found the Mustang's hidden compartment. I hoped you never would."
Marcus stopped.
He sat down.
The letter continued.
"There are things I never told you because I believed keeping you away from this history was the safest thing I could do."
Marcus swallowed.
"Samuel trusted me with information that could have destroyed powerful people. I helped him hide it. After he disappeared, I kept quiet."
Marcus looked toward the garage door.
He suddenly felt as though someone might be watching him.
"I don't know whether the people involved are still looking for what Samuel hid. But if you ever restore the Mustang, remember this: the car isn't valuable because of what it is. It's valuable because of what it carries."
Marcus read the final paragraph.
"If someone suddenly becomes very interested in the car, be careful."
Marcus lowered the letter.
His mind returned immediately to Evelyn.
Her accusations.
Her insistence.
Her strange certainty that the Mustang was causing trouble.
He didn't want to accuse her of anything.
But now he couldn't ignore the possibility that someone else knew about the car.
The next morning, Marcus went to the police station.
He asked for Officer Harris.
When Harris saw him, he immediately noticed the concern on Marcus's face.
"What happened?"
Marcus placed the letters on the desk.
"I found these inside my car."
Harris read them carefully.
"You think this is connected to the complaint?"
"I don't know."
Harris looked at the old photographs.
"Who's this?"
"My father."
"And the other man?"
"Samuel Walker."
Harris studied the name.
"We can look into it."
Marcus nodded.
"There was another thing."
"What?"
"Someone knew about the car before I did."
Harris leaned back.
"Who?"
"Evelyn Carter."
Harris was silent.
"Why do you think she knows?"
"Because of the way she reacted."
Harris didn't immediately agree.
"That's not evidence."
"I know."
"Then don't make accusations based on a feeling."
