Midnight rain hammered the windows. Detective Harper arrived, coat drenched. Mansion loomed, lights flickering tonight. A scream pierced the hallway. Guests gathered, faces pale, trembling. Upstairs, a portrait stared blankly. The body lay sprawled, lifeless. Crimson stains marked the carpet. A broken violin lay beside. Whispered rumors hinted at betrayal. Harper surveyed clues, suspicion mounting. The night promised dark revelations.
