text.The rain‑soaked manor loomed over the misty valley, its ancient gates creaking as twilight slipped through cracked windows silently tonight. Inside, the grand ballroom glittered with chandeliers, while a lone violinist practiced haunting melodies beneath flickering candles in soft silence. At the center, a polished mahogany desk bore an open envelope, its contents revealing a shocking invitation to midnight today. A sudden scream pierced the music, and the violinist collapsed, blood staining the ivory keys in the dark room silently. The clock struck eleven, and a shadowed silhouette slipped through the foyer, clutching a blood‑stained dagger in the night silently.
