## The Silent Echo Detective Morgan arrived at the crime scene on a rainy night. The yellow tape fluttered gently in the wind around the house. Raindrops tapped a melancholy rhythm on the wooden porch steps. A single light bulb swayed from the ceiling inside. The victim lay sprawled across the antique Persian living room rug. Blood had seeped into the intricate patterns of the fabric. Detective Morgan knelt down to examine the mysterious golden cufflink. It didn't belong to the victim, a woman named Sarah. Her phone was missing, but her wallet remained untouched nearby. The murderer had been careful, methodical, almost surgically precise perhaps. On the wall hung a family portrait with one face scratched out. Morgan noticed the faint scent of expensive cologne lingering behind. The grandfather clock in the hallway had stopped at midnight exactly. Outside, a neighbor watched from their window with fearful eyes. Something about this scene felt personal, vengeful, and coldly calculated.
