The rain fell silently over the abandoned manor's creaking gates. Inside, a candle flickered, casting shadows across the dusty hallway. A single portrait stared back, its eyes hollow and accusing. The clock struck midnight, its chimes echoing through stone corridors. A sudden scream shattered the silence, echoing from the library. The library's books fell like snow, revealing a bloodstained page. On the page, the victim's name was written in crimson. The ink glowed as if the blood itself had spilled.
