The clock struck midnight, echoing through the dimly lit mansion. A chilling wind howled outside, rattling the ancient window panes. Detective Harper arrived, his coat flapping like a restless shadow. The grand chandelier flickered, casting eerie shadows on the walls. A scream pierced the silence, sending shivers down Harper's spine. He followed the sound, footsteps echoing on the marble floor. In the library, a body lay sprawled across the carpet. Books lay scattered, as if a struggle had taken place. A single candle burned, illuminating the victim's lifeless, pale face. Harper knelt down, examining the scene with a practiced eye.
