Murder she wrote

Prologue: (Non-extended version)

His eyes grew wide as his body collapsed to the floor. I drew the knife from his chest as I watched him gasp for air. He kept heaving, as if gasping for more life. I stood silent as his blood seeped to the carpet. I couldn't watch. I dropped to my knees and looked to the ground until his breathing got slow and unsteady. He made a small grunt in pain.
"Rose", he called out.
A tear streaked down my eye as I heard his final breath. And then...nothing. I walked out the room, not bothering to look back at what I left behind. It was done. He was dead.
My name is Rosalie Cole. And this is my story.
