The stormy night cloaked the abandoned manor's creaking hallways silently. Inside, a single candle flickered, casting shadows across polished mahogany. A violinist played a mournful minor, his bow trembling softly. At the piano, a portrait stared, eyes tracking every movement. Suddenly, a scream shattered silence, echoing through stone corridors. The chandelier fell, striking the floor, revealing a hidden dagger. Detective Marlowe entered, eyes narrowed, noting the bloodied scythe there.
