Just then, chilling laughter echoed inside, sending shivers down Raegan's spine.

Raegan scanned the interior. Apart from the chaos unfolding above, the car was empty.

The car's speakers crackled to life. “Hello, how are you?"

Raegan could detect the foreign lilt in the distorted voice.

“Cat got your tongue? Or are you just frightened?" the voice prodded her.

With composed intensity, Raegan asked, "Who's this? Who's behind this?"

The reply came with a mirthless chuckle, skirting a straight answer.

“The person trying to kill you and I are after the same target. But her way of dealing with you is too pedestrian for my taste. I've made some enhancements."

Raegan pressed on, her tone unyielding, "What do you mean by that?"

The voice drew out its response with unnerving calm. "Think of it as a significant upgrade. There's enough firepower in this vehicle to turn a skyscraper to dust.”

A surge of panic raced through Raegan. Her gut screamed at her to bring the car to a halt.

The voice in the speakers gave a knowing laugh. “Just a friendly heads-up. The second you leave that seat, boom. It all goes up.”

Raegan, rooted to her spot, yelled, “You're mad! This is murder! What you're doing is a crime!"

“A crime? Interesting!" The voice treated her accusation as a joke.

“Do you really think you'll make it out of this to point the finger at me?"

"Who are you?" Raegan's voice was sharp with demand.

The caller played coy. "Think of yourself as a failed project of my experiments that I'd like to end you personally."

Her mind racing, Raegan connected the dots. "You're the one who tried to kill me five years ago, with the car crash?"

“Sharp as a tack!" the voice doled out mock praise. "Such a pity you will meet your end soon. Such brains in a pretty package."

Frustration nipped at Raegan. “Katie's behind this, isn't she?"
