Rain battered the silent manor. Midnight thunder shook broken windows. Red blood stained antique carpet. Footsteps echoed down empty corridors. A scream pierced heavy darkness. Detective Harper entered crime scene. She surveyed the gruesome tableau. Candles flickered, casting ominous shadows. A shattered mirror reflected horror. Someone whispered secrets in darkness.
