Thunder rumbled above silent manor. Footsteps echoed down deserted hallway. Candlelight flickered against peeling wallpaper. A scream shattered midnight stillness. Detective Valen studied crimson stain. Blood pooled beneath broken chair. Rain tapped against dusty windows. Portraits glared with accusing eyes. Footsteps approached down distant corridor. Someone whispered secrets in darkness. Detective’s heart pounded against ribs. A shadow slipped behind curtains. Silence returned with ominous weight.
