The rain fell hard against the old mansion windows. Detective Cole stepped inside, boots squeaking on polished floors. A single lamp flickered, casting long shadows down the hall. The air smelled thick with dust and something metallic. Voices murmured behind the heavy oak door ahead. He adjusted his gloves, fingers trembling just slightly. A woman’s scream shattered the silence like broken glass. Cole sprinted forward, heart pounding in his chest. The door swung open to reveal a bloodstained room. A body lay sprawled across the Persian rug.
