Rain hammered the cobblestones as Detective Mara entered the dimly lit manor, her coat dripping with midnight mist and silence. A shattered crystal vase lay beside the grand piano, its shards glinting like blood under the flickering chandelier of danger. Mara's flashlight beam revealed a faint, crimson stain on the Persian rug, spreading slowly toward the hallway doorway of trouble. A distant clock struck midnight, echoing through empty corridors as the house seemed to hold its breath, waiting for justice.
