The rain fell heavily upon the dark roof of the old mansion while shadows danced softly within the empty halls. Detective Miller stepped carefully inside the dusty room where the cold body lay still upon the red velvet floor tonight. A single candle flickered weakly near the broken window that showed nothing but darkness outside the heavy wooden main entrance. The blood on his white shirt matched the color of the roses that grew wildly in the nearby garden now.
