Thunder rattled windows as Detective Lee entered the grand, silent manor. A clock chimed midnight, echoing through halls draped in velvet gloom. Rainwater dripped from Lee’s coat, pooling beside his careful footsteps. A candelabra flickered, casting shadows that danced along ornate portraits. He followed the faint scent of roses mingled with something metallic. In the parlor, guests huddled together, faces pale with silent dread. The butler’s trembling hands pointed toward the library’s slightly open door. Lee pushed it slowly, revealing chaos and a lifeless figure sprawled. Blood stained the carpet beneath the lawyer, Mr. Jameson’s elegant shoes. A single clue remained: one white glove caught beneath the body.
