The clock struck midnight in the old mansion’s grand hall. Shadows danced eerily beneath the flickering chandelier’s dim light. Detective Harper stepped inside, noting every detail with sharp eyes. A body lay motionless, sprawled across the antique rug’s center. Blood stained the velvet curtains, dark against the crimson fabric. Glass shattered nearby, hinting at a struggle moments before death. No one else dared enter; the house was locked tight. Whispers echoed down the long hallway, secrets waiting to unravel. Harper knelt, examining the victim’s hand clutching a torn note. The mystery had begun, and answers hid in silent darkness.
