Chapter 10 - the last twenty minutes

The video lasted eighteen minutes and forty-three seconds.
Detective Brooks allowed Rachel and Margaret to hear the audio portion two days later.
No images.
The visual evidence remained restricted.
Rachel was grateful.
Hearing Caleb die once was enough.
At 6:24 a.m., a door opened.
Caleb's footsteps entered the kitchen.
He sounded exhausted.
"Where's Mark?"
Vanessa replied.
"Gone."
"What did you do?"
"Nothing."
"I saw the knife."
Silence.
"Vanessa."
"What?"
"What did you do?"
She answered.
"The same thing you were going to do to me."
"What does that mean?"
"You were leaving."
"Yes."
"Taking everything."
"No."
"Taking my child."
"I'm taking Noah away from this."
"I'm his mother."
"And I'm his father."
"You haven't even met him."
"I will."
"You think you're going to raise my son with your mother and Rachel?"
"If that's what keeps him safe."
A chair scraped.
Vanessa's voice changed.
"Safe from me?"
"Safe from this."
"You're calling the police."
"I'm calling an attorney first."
"I knew it."
"Vanessa, I know about Mark. I know about the money. I know about the truck."
Long silence.
Then Vanessa whispered.
"You don't know anything."
"I know enough."
Another sound.
Keys.
Caleb continued.
"Don't follow me."
"Where are you going?"
"Mom's."
"Caleb."
"Move."
"You can't do this."
"I already did."
The next sound was a slap.
Not a hand.
Something striking the counter.
Vanessa screamed.
"You ruined everything!"
Caleb shouted back.
"I didn't steal thirty thousand dollars!"
"You changed the insurance!"
"Because you're stealing from us!"
"You gave everything to a baby who isn't even born!"
"He's my son!"
"He's the reason you started watching every dollar!"
"No. You are."
Footsteps.
A door.
Caleb's voice farther away.
Then Vanessa said something so quietly investigators almost missed it.
"If you leave in that truck, don't expect to come back."
Rachel's blood turned cold.
Caleb replied.
"What?"
Vanessa said nothing.
The mudroom door slammed.
The video continued recording the empty kitchen.
For twenty-three seconds, nothing happened.
Then Vanessa reentered.
She was crying.
She picked up the old phone.
The image moved.
The recording stopped.
Rachel sat motionless.
Margaret had both hands over her face.
Detective Brooks switched off the speaker.
"That isn't proof she cut the line," Rachel said.
Her own voice sounded far away.
"No."
"But she knew."
"It supports that inference."
"Mark says he fixed it."
"Yes."
"Camera shows Vanessa taking a utility knife outside."
"Yes."
"Then she tells Caleb not to leave in the truck."
"Yes."
Rachel stared at Brooks.
"How is she not arrested?"
The detective's phone rang.
She checked the number.
"She may be."
Twenty minutes later, Vanessa Carter was arrested.
Charges initially included child endangerment, financial fraud, evidence tampering, and conspiracy related to vehicle sabotage.
A homicide charge would depend on the prosecutor's review and additional forensic analysis.
Rachel expected relief.
Instead she felt empty.
Police cars appeared on television that night.
Reporters stood outside Vanessa's attorney's office.
Mark's name became public.
So did Caleb's.
Rachel turned off every screen in the house.
Noah didn't need his father's death turned into entertainment.
Three days later, the forensic vehicle examiner called Detective Brooks.
A section of brake line recovered from Caleb's truck showed two distinct areas of tool damage.
One older.
One newer.
The newer cut pattern was consistent with a narrow utility blade.
The same type of blade recovered from Vanessa's garage tool drawer.
That still wasn't perfect proof.
But investigators found more.
A tiny smear of brake fluid on the old gray sweatpants Vanessa had placed in a donation box after Caleb's funeral.
Police had recovered the box during the house search.
Vanessa's attorney argued contamination.
Prosecutors disagreed.
Then Rachel received a letter.
Not from police.
From Vanessa.
Her attorney had approved it.
Rachel almost threw it away.
Margaret told her not to open it.
Rachel waited until Noah was asleep.
Then she did.
Rachel,
You hate me.
I understand.
You think Caleb was perfect because he was your brother.
He wasn't.
He controlled everything.
Money.
House.
My pregnancy.
He watched accounts like I was an employee.
He changed his insurance without telling me.
He planned to take my son.
Mark was a mistake.
The money was a mistake.
The truck was supposed to scare Caleb.
That is the truth.
I never asked anyone to kill him.
What happened that morning was not planned.
He came home angry.
He said he would destroy me.
I wanted him to stop.
I wanted him to feel afraid.
That is all.
As for Noah, you saw one moment after weeks of no sleep.
I would never hurt my son.
You need to remember that he is mine.
Not yours.
You have already taken my husband from me by turning him into some saint.
Do not take my child too.
Vanessa
Rachel read it twice.
The first time with anger.
The second time carefully.
One sentence would not leave her mind.
What happened that morning was not planned.
Rachel took a photograph of the letter and sent it to Detective Brooks.
Brooks called five minutes later.
"Do not respond."
"I wasn't going to."
"This sentence matters."
"I know."
"She may have just placed herself at the center of the final sabotage."
Rachel looked toward Noah's bassinet.
"What happens now?"
"We keep building the case."
Rachel folded the letter.
"How long?"
"As long as it takes."
Weeks, Rachel thought.
Months.
Maybe years.
She wanted an ending.
Instead she had evidence.
Then Brooks said something Rachel had not expected.
"We found Dennis."
Rachel stood.
"The garage owner?"
"Yes."
"I thought you already talked to him."
"He disappeared after the crash."
"What?"
"He closed the shop and left the state."
"Why?"
"He says someone threatened him."
Rachel's fingers tightened around the phone.
"Who?"
May you like
Brooks paused.
"Vanessa."
