Flash Fiction: The driver did it

This short flash fiction piece has a surprising twist at the end that will leave you shocked

---

I enter the car and sit in the back.

"Good evening sir."

"Good evening, Linda."

"So, are you still going to that conference sir?"

"Yes, get me there as fast as you can."

My wife waves goodbye to me, standing in the driveway. My beautiful daughter is there, standing by her mom. I'll buy her a new wardrobe and anything else she asks for, for her birthday. She's turning 14 next week.

I wave back and they start their walk back into the house.

That idiot loan shark thought he could threaten me. "Don't leave your family alone anytime soon," I mockingly repeat his warning to myself. I've got security personnel all over the place, I dare him to try.

"What was that sir?"

"Oh, nothing Linda. Let's go."

"Okay."

She starts the engine and I hear a beeping noise coming from somewhere inside the car.

"What's that noise Linda?"

Linda gets out of the car and shuts the door.

"Linda! What are you doing?"

She walks away and stops a few feet away. I look at her and a dread grips me. I try to open the door to get out, but it's locked. I try all the other ones and find out that I'm locked in.

"Linda!"

She smiles, waves and walks into the house. She's now holding a gun. My phone rings and I answer it.

"Hello."

"You should've given me my money on time."

The beeping sound grows louder and louder, until...... BOOM!!!
