Midnight rain hammered the cobblestones as Detective Marlowe entered the dimly lit manor, his breath visible through the foggy air. A shattered chandelier hung over the ballroom, its crystal shards glittering like frozen stars against the crimson walls of silence. At the center, a lifeless body lay draped in silk, a silver knife protruding from the chest of dark blood. Marlowe examined the scene, noting the faint scent of lavender mingling with metallic iron, hinting at hidden motives for justice. Suddenly, a mournful violin echoed through corridors, and the portrait eyes seemed to follow, daring anyone to uncover truth alone.
