The rain fell hard upon the old roof while thunder shook the very walls inside the house. A single candle flickered low within the hall as shadows danced along the floor with quiet grace. The door swung wide to show a man who lay quite still upon the cold and dirty stone. His eyes were open wide to see the ceiling but he saw nothing at all in that dark room. A pool of red began to spread beneath his chest and touched the boots of someone standing near. That person wore a mask of black velvet that covered every feature of their face completely well. They held a silver knife within one hand while wiping blood upon the heavy silk curtain there. Silence filled the space between the lightning flashes that lit up the scene with stark white light. No sound came from the kitchen where a clock had stopped ticking just before the murder happened now. The killer turned around to face the window where the storm raged outside with powerful wind and rain.
