Midnight rain drenched the manor. Crimson footprints stained the carpet. A single candle flickered dimly. Detective Archer surveyed silent hallway. A piercing scream echoed upstairs. Footsteps pounded against wooden floors. Blood spattered across old wallpaper. A lifeless body lay motionless. Glass shattered under frantic footsteps. Archer’s eyes glinted with determination. Night’s secrets awaited their reveal. Silence enveloped ominous grand estate.
